Spring Valley Reservoir, a 56 acre artificial lake, was selected for study. Field work extended from May through November, 1964, but certain phases of the laboratory work were not completed until March, 1965. Particular attention has been given to vertical and seasonal variations of zooplankton populations in reference to selected environmental factors such as temperature, transparency, dissolved oxygen, free carbon dioxide, total and calcium hardness, alkalinity, nitrogen, and phosphorous. In addition, emphasis has been given to the mean summer standing crop of zooplankton. Although limnology has been recognized as a distinct branch of science for less than 70 years (Welch, 1952), much has been done to provide an understanding of lake productivity and the numerous factors influencing productivity . Many investigations have been conducted in an attempt to determine characteristics with which to classify the productivity of lakes. As a result, many physical, chemical, and biological measures of productivity have evolved and are now used with varying degrees of success. Some of these limnological methods have been included in the present investigation.", "collection": "Palouse Basin", "contributors": "Idaho Water Resources Research Institute; IWRRI", "publisher": "Idaho Water Resources Research Institute, University of Idaho", "contributing-institution": "University of Idaho", "source": "Idaho Water Resources Research Institute, University of Idaho", "identifier": "IWRRI Number 196501", "language": "eng", "rights": "In copyright, educational use permitted.

Irrigation development costs of bringing the water to the headgates of the farms are not included in this phase of the study. Data was secured for 8 farms by interviewing each farm operator and land owner. To make comparisons between farms and also between enterprises, the data were broken down into per acre variable costs, fixed costs, total returns, net income and the cost of producing a dollar's worth of output. The term "cost per dollar of output " is the ratio of costs to returns. This ratio makes it possible to compare high-valued crops with low-valued crops on a per acre basis. This is a very sensitive measurement. For example, one cent change in the ratio for potato enterprise means a change in net income of $3.25 per acre. The budgeting method of estimating water values in irrigation was used in this study. Long-run planning cost curves were estimated from the budgets by using simple curve linear regression. From the regression equations for each of the four enterprises (grain, sugar beets, potatoes and alfalfa seed), 12 model farms were constructed. The long-run average total cost curve for the model farms, which incorporates a long-run rotation and long-run price and yield expectations, indicated economies of size up to a farm size of 2,400 acres.

A numerical model of regional groundwater flow was developed to evaluate (1) the effects of large-scale increases in groundwater withdrawals on regional groundwater levels and (2) the potential effects of altered recharge rates (associated with conversion of agricultural to urban land use) on regional groundwater levels. The model was constructed using the three-dimensional, finite difference MODFLOW code (Harbaugh et al., 2000; McDonald and Harbaugh, 1988; McDonald and Harbaugh, 1996). The model was calibrated under steady-state hydraulic conditions using the automated parameter estimation code PEST (Doherty, 1998; Doherty, 2000). Horizontal and vertical hydraulic conductivity parameters were calibrated to 200 averaged water level observations and 6 actual and estimated vertical head differences. The model calibrated with higher hydraulic conductivity values in the uppermost aquifer zones, corresponding with known areas of coarser-grained sediments. PEST-calibrated parameter values also indicated relatively high hydraulic conductivity values in areas of the eastern and central portion of the valley associated with fluvial/deltaic deposition. Simulated fluxes between model layers in the base calibration indicated a relatively small amount of water moves vertically between model layers, especially in the lower layers. Based on simulation results, most recharge that occurred in shallow aquifer zones did not reach deeper zones. A 10% increase or decrease in recharge led to minimal changes in water levels or parameter value estimates because shallow groundwater levels in central portions of the basin are controlled, in part, by elevations of surface water channels. Decreased or increased recharge resulted in changes in the rates of water discharging to model drain, general head boundary (Lake Lowell), constant head (Snake River), and river (Boise River) cells. Changes in land use that lead to decreases in shallow-aquifer recharge may not have a substantial effect on shallow groundwater levels until the water table elevations remain below those of nearby surface channels. Simulations indicated that some groundwater level declines might occur with a 20% increase in groundwater withdrawals over 1996 levels. Modest simulated declines were observed in the Boise area in layers 1 and 2. Greater simulated declines were observed in the central portion of the valley (especially in the Lake Lowell area) in layers 3 and 4. The simulated 20% increase in groundwater withdrawals resulted in increased losses from the Boise River (23%), decreased discharge to agricultural drains (62%), and decreased discharge to the Snake River (9%). Simulated water level declines andlor changes in mass balance components reflected a combination of parameter uncertainty and response to a changed hydraulic stress.", "collection": "Boise Basin", "series": "Research Report", "contributors": "IWRRI; Idaho Department of Water Resources; Urban, Scott; Doherty, John", "publisher": "Idaho Water Resources Research Institute, University of Idaho", "contributing-institution": "University of Idaho", "source": "Idaho Water Resources Research Institute, University of Idaho", "identifier": "IWRRI Number 200402", "language": "eng", "rights": "In copyright, educational use permitted.

The additional water is being requested for irrigation, municipal, commercial, and aesthetic uses. The water requested for non-supplemental purposes could represent approximately a 20% increase over 1996 levels of groundwater withdrawals. The potential impact of processing these new well applications on regional groundwater levels was evaluated using the Treasure Valley groundwater flow model (Petrich, 2004a). The Treasure Valley groundwater flow model was constructed with the USGS MODFLOW code (McDonald and Harbaugh, 1996) and calibrated to steady-state hydraulic conditions using the PEST parameter estimation code (Doherty, 2000). The calibration was based on over 200 water level and 6 vertical head difference observations. Predictive analysis (Doherty, 2000) was used to estimate worst (and best) potential outcomes given parameter non-uniqueness in the calibrated model. The simulation results indicated that aquifer level declines might occur if all of these currently unprocessed, non-supplemental, groundwater rights were granted. Water level declines could be in the range of 10 feet to over 40 feet, depending on valley location, actual amount of withdrawals, and depth of extraction. Local areas of simulated declines were noted south of Lake Lowell in an area in the northwestern portion of the model and in portions of an area between Boise, Meridian, and Kuna. These may be associated with unrealistically high simulated stresses or excessively low simulated aquifer parameter values. The simulated declines also may indicate potential problems in supplying the increasing groundwater demands in these areas. The least declines were predicted in the uppermost model layer, which corresponds roughly with the uppermost 200 feet of aquifer. Most of the estimated new simulated withdrawals in the uppermost layer resulted in decreased discharge to drains. The simulated declines presented in this report are the result of both calibration effects and increased withdrawals. Additional comparisons between minimum base calibration heads and prediction heads should be conducted to refine these predicted declines.", "collection": "Boise Basin", "series": "Research Report", "contributors": "IWRRI; Idaho Department of Water Resources; Urban, Scott; Doherty, John", "publisher": "Idaho Water Resources Research Institute, University of Idaho", "contributing-institution": "University of Idaho", "source": "Idaho Water Resources Research Institute, University of Idaho", "identifier": "IWRRI Number 200403", "language": "eng", "rights": "In copyright, educational use permitted.

Mining operations in the past have discharged huge amounts of mining wastes into the South Fork of the river causing a serious pollution problem for the Coeur d'Alene River system. Sediments in the South Fork and the Main Stem of the river are contaminated with arsenic(As), antimony(Sb), cadmium(Cd), Lead(Pb), Zinc(Zn), and other metals. The North Fork water was found relatively uncontaminated and showed very low concentrations of As ( <0.26 ng/mL) and Sb ( <0.17 ng/mL). Water samples collected from the South Fork showed high levels of As (0.16-1.64 ng/mL) and Sb (1.11-8.25 ng/mL). Relatively lower concentrations of As (0.11-1.48 ng/mL) and Sb (0.23-1.90 ng/mL) were found in the main stem of the river. Arsenic(lll) was the predominant form of As in the South Fork and main stem, whereas the North Fork generally had a higher As(V) concentration in water. Antimony(V) was the major Sb species in the three branches of the river. Leaching of As and Sb from the sediments along the main stem depends on the pH of the water and on the iron and manganese content of the sediments. The amount of As and Sb leached was high in acidic or in basic solutions. The enhanced desorption of As and Sb in basic solutions was probably related to the anionic properties of these elements. An accumulation of As and Sb on the surface sediments was also observed in the delta area where the river enters Lake Coeur d'Alene. The releases of As and Sb from the sediments appear to associate with the free iron oxides and manganese oxides in the sediments. The leaching characteristics of Sb are similar to those of As. However, releases of sediment Sb were generally found linear with respect to time while asymptotic limits on As releases were reached. Significant amounts of Zn, Fe, and Mn were also released during leaching, but Cu, Cd, Ph, and Ni were much less leachable. According to this study, interaction of water with the existing sediments is likely to be a major factor controlling the water quality of the Coeur d'Alene River.", "collection": "Coeur d'Alene Basin", "series": "Water for Idaho", "contributors": "Idaho Water Resources Research Institute; IWRRI", "publisher": "Idaho Water Resources Research Institute, University of Idaho", "contributing-institution": "University of Idaho", "source": "Idaho Water Resources Research Institute, University of Idaho", "identifier": "IWRRI Number 198906", "language": "eng", "rights": "In copyright, educational use permitted.

These investigations were made in an attempt to answer questions as to the passage of metallic elements through the aquatic food chain in the study area as well as to determine the critical factors involved in the poor recovery of the South Fork and main stem of the Coeur d'Alene River. Additional work was carried out to determine the water quality of these areas and the Spokane River. Extensive studies were also made upon the substrata and limiting factors for macroinvertebrates of the Upper Spokane River. Artificial substrates (baskets) placed in the unpolluted portions of the Coeur d'Alene River developed abundant and diverse macroinvertebrate fauna comparable to that collected from natural substrata by Surber Sampler. Flooding of Coeur d'Alene River during the spring highwater period transports heavy metals, especially Zn, into the lateral lakes bordering the river. Zinc concentrations in the lake water were highest near the lake inlets. Metal concentrations in fishes from the lakes were higher than those tested from a control lake in the St. Joe drainage. There appeared to be greater Zn concentrations in the muscle tissues of omnivorous fish such as the bullhead than in the same tissue of piscivorous fish such as the largemouth bass. The fishes seem to be exerting some homeostatic control over the metal level in their tissues. The overall water quality of Coeur d'Alene Lake appeared to be relatively the same as the found in our earlier study (Funk, Rabe, and Filby et al., 1973) based upon routine water sampling during coring operations and on data gathered from a water quality station maintained at the lake outlet. Nineteen sediment cores were obtained along the lengthwise axis of the lake and from selected bays. A layer of heavy metals 80-30 cm in thickness occurred in the Coeur d'Alene delta region and lake proper. This layer decreased in thickness as one traversed the lake from off the delta region toward the outlet where the layer is reduced to 5 cm. Coring operations from the delta region of the lake toward the southern end revealed the same phenomenon occurred to a lesser extent to a point between the area of Conkling Park and Chatcolet Lake. This layer of heavy metals could constitute a hazard to aquatic life if Coeur d'Alene Lake eutrophies to the point of anaerobic conditions in the hypolimnion. The biological productivity of the Spokane River is largely controlled by the water quality of Coeur d'Alene Lake as well as by the substrate, temperature and flow of the river. Nutrient additions to the river as it flows toward the city of Spokane increases the productivity of the lower four stations, especially at the Plantes Ferry station. Heavy metals, such as Zn, Cu, and Pb, appear to be concentrated to relatively high amounts in algae, aquatic macrophytes and other vegetation growing along the river. Algae and detritus-consuming macroinvertebrates such as mayflies and stoneflies pass these metals along to the fishes, especially trout because of the trout's predilection for these organisms. However, there appears to be a reduction of concentration of metals in tissues at each trophic level as one moves up the food chain. The organisms appear to be actively excreting the metals. In the fishes, the filter bodies such as the kidneys and liver concentrated the metals several-fold over that of other tissues and therefore tend to confirm this assumption. Nonetheless, the level of Zn, for example, in the muscle tissue of Spokane River fishes may be two to three times that in muscle tissue of the same species taken from undisturbed streams high in Coeur d'Alene drainage. For these reasons it has been concluded by the investigators that additional efforts should be made to curtail and control seepage from tailings ponds as well as reduction and eventual control of wastes and nutrient runoff in the Coeur d'Alene and Spokane river drainage basins.

In certain instances these blooms produce a toxin which can be lethal to fish, aquatic invertebrates, mammals and humans. Black Lake in northern Idaho has experienced massive late summer and fall growths of a toxic algae, Nostoc commune. At times, demonstrated fatal toxicity to cattle and small mammals has resulted in three of the last four years. Since little is known of the exact environmental conditions required to cause toxicity, environmental and phytoplankton parameters were monitored throughout the lake during summer and fall, 1984. Although conditions seemed favorable, and other blooms were intermittent through the summer-fall 1984, Nostoc did not develop to bloom proportions and toxicity did not occur. Algal assay results showed that algal growth potential ranged in the very productive range of -1 9.60 to 12.16 mg dry weight 1 /14 days for the late summer-early fall period. The limiting nutrient switched from phosphorus to nitrogen during the fall months, also indicating the potential for a Nostoc bloom. All indicators showed that Black Lake was highly productive in 1984 despite the absence of a toxic Nostoc bloom. Water transparency ranqed from 0.8 to 3.4 m, averaging 1.2 m from June to October. pH values went as high as 8.2, with the total absence of CO2 in some of the littoral areas. Dissolved oxygen values were at super saturated levels throughout most of the sampling regime. Diatoms (Fragilaria sp., Melosira sp., and Asterionella sp.) dominated the phytoplankton composition with Nostoc only showing up in early August. Chlorophyll 11 a11 values correlated with phytoplankton trends, with highs of 15 to 31 mgl-1, and lows of 0 to 5 mgl-1. The fact that Black Lake is clearly eutrophic, and that the potential for a blue-green bloom was present but did not materialize, may possibly be explained by two factors ... climatological trends and stratification pattern. The absence of a well developed hypolimion along with excessive cloudiness and lack of a protracted calm, bright, and warm fall may have accounted for the lack of a toxic bloom in Black Lake during 1984.", "collection": "Coeur d'Alene Basin", "series": "Water for Idaho", "contributors": "Idaho Water Resources Research Institute; IWRRI", "publisher": "Idaho Water Resources Research Institute, University of Idaho", "contributing-institution": "University of Idaho", "source": "Idaho Water Resources Research Institute, University of Idaho", "identifier": "IWRRI Number 198508", "language": "eng", "rights": "In copyright, educational use permitted.

The project was sponsored by the Idaho Division of Environmental Quality (Coeur d'Alene office). Objectives of the study were to: 1) Characterize baseline river water quality; 2) determine seasonal river water quality variation; 3) assess diel temperature and dissolved oxygen changes for indications of aquatic ecosystem stress; and 4) provide a cursory view of the effects of existing and proposed wastewater discharges on river water quality, to the extent that river water quality data and WWTP data will allow. The study updated earlier work by the University of Idaho and USEPA in 1980 and 1988. The study area covered the 8.1-mile reach of the Spokane River from the outlet of Lake Coeur d'Alene at River Mile 108.8 downstream to just below Post Falls Dam at River Mile 100.7. This reach is typified by swift water currents and cobble bottom channel in the upper section merging to deeper, slower lacustrine conditions in the lower section where channel cobbles yield to fine sediments in lateral embayments. Water depths ranged from 2 to 18 m through the reach. Water flows in the 16-month study ranged from high flows of 31,750 cfs in May, 1990 to low flows of 340 cfs in September, 1990. Retention times of the study reach varied from 4.3 hours at annual high flows in 1990 and 1991, respectively, to 12.7 days at annual low flows in 1990 and 1991. Surface water temperatures peaked at 25.7 and 26.1 C in 1990 and 1991. Vertical thermal stratification was minimal, always less than 3.0 C from surface to bottom. Slight summer temperature increases were noted downstream through the reach. Sample site mean summer dissolved oxygen was always greater than 7.0 mg/1; one sample occurrence was recorded of 5.4 mg/1. Electrical conductivity generally ranged from 30 to 55 umhos. Median pH was slightly on the acid side (5.7 to 7.8) throughout the reach. Secchi depth ranged from 2.4 to 6.5 m with a study average of 4.0 m. High flows coincided with low secchi depths, as a result of suspended sediments and an extended spring algae pulse. Mean year-round chlorophyll a averaged 2.5 and 4.2 mg/m3 at the upper and lower sections of this river reach for an average 73% increase over the 7.6 mile reach. Mean summer chlorophyll a of the lower sections averaged 6.0 mg/m3 in 1990 but only 3.3 mg/m3 in 1991 (= 45% reduction) following 1) a very large spring algae bloom, and 2) 80% phosphorus removal from the Coeur d'Alene WWTP. The 1990 and 1991 chlorophyll a levels place the Spokane River in mesotrophic and meso-oligotrophic productivity ranges, rexi spectively. Mean Kjeldahl nitrogen was 0.18 mg/1 and generally increased >20% below the Coeur d'Alene WWTP at low flows. There was a general trend of TKN increasing downstream through the study reach. The WWTPs contributed 25 to 50% of the TKN load to the Spokane River at low flows. Nitrate nitrogen was typically less than 0.05 mg/1 through summer months with fall-winter maxima of 0.50 mg/1. At low flows, WWTPs supplied 40% of the total nitrate load to the river. Mean total ammonia in the Spokane River arm of Lake Coeur d'Alene was 0.14 mg/1. From RM 111.1 to 108.8, there typically was an average 75% increase of total ammonia in the River, but less than one third of that increase was from the Coeur d'Alene WWTP. However, 30% of the average summer ammonia load to the river was from the Coeur d'Alene WWTP (up to 60% of the total ammonia load in September, 1991 at 340 cfs river flow). Total phosphorus ranged from 0.007 to 0.025 mg/1 with a study mean of 0.014 mg/1 (in the mesotrophic range). Total phosphorus increased 70% between RM 111.1 and 108.8over the entire study. Summer total phosphorus increased 87% between RM 111.1 and 108.8 over the entire study, 187% in 1991, but showed a 30% decline in 1991 after phosphorus removal in the Coeur d'Alene WWTP. WWTPs contributed -50% of the total phosphorus load to the reach at low flows. Upgrading the Coeur d'Alene WWTP in June, 1991 resulted in an effluent TP decline of 79%. Total N:total P ratios indicate phosphorus limitation most of the time with the exception of summer-fall 1990. BODs levels in the Spokane River were moderately high, averaging 3.4 mg/1 over all sites and dates. WWTP BODs levels from the Coeur d'Alene and Post Falls plants averaged 81.2 and 13.2 mg/1, respectively. Mean BODs increased 14% in the lower four river sites compared to the two upstream sites. Ultimate BOD in the Spokane River averaged 10.7 mg/1. WWTP ultimate BOD levels from the Coeur d'Alene and Post Falls plants averaged 644.7 and 371 mg/1, respectively. Mean ultimate BOD increased 11% in the lowest river site compared to the uppermost site. Median fecal coliform bacteria in the Spokane River were -1 colony/100 ml except for immediately below the WWTPs. Median fecal coliform bacteria were 30 and 24 colonies/100 ml in the Coeur d'Alene and Post Falls WWTPs, respectively. Median fecal coliform bacteria increased -30-fold from above to immediately below the Coeur d'Alene WWTP. River fecal coliform levels dropped to background concentrations within two river miles. Median fecal coliform bacteria increased -2-fold from above to immediately below the Post Falls WWTP.

The upper sediment layers in Lake Coeur d'Alene are enriched in heavy metals and the lake appears to be becoming more eutrophic. The geologic history of the region contributes to the understanding of the hydrogeology of the study area. The coarse-grained glacial outwash aquifer is bounded below by fine-grained sediments of the Latah formation, and bounded laterally by Precambrian sediments and metasediments. A conceptual model for surface water/groundwater interaction reveals that the cross sectional area of the aquifer increases from the northern end of Lake Coeur d'Alene farther into the aquifer. This could account for the steep hydraulic gradient from the lake to the aquifer. The steep gradient could also be a result of fine sediments which have infiltrated the glacial outwash and have decreased the hydraulic conductivity of the aquifer, adjacent to the lake. Evidence for the infiltration of fine material exists in grain size analyses and unpublished reports. Lake Coeur d'Alene is dimictic and oligotrophic to eutrophic. Oxygen enrichment in the epilimnion and depletion in the hypolimnion are well-documented phenomena in eutrophic lakes. Dissolved oxygen concentrations as low as 52% were measured by the USGS northeast of Blue Point near Harrison in September, 1991. Anoxic, reducing conditions in the hypolimnion during summer stratification of the water column may cause Mn and Fe mobilization from sediments. Dissolved heavy metals in the hypolimnion are likely to coprecipitate with Mn oxyhydroxides (and to a lesser extent iron hydroxides) when the metals encounter more oxygenated water. Seismic profiles of the lake bottom indicate that fine, laminated sediments cover the central portions of the lake and thin out near the lake margins. These sediments contain elevated metals concentrations in both particulate form and in sediment pore water. The concentration gradient of metals in pore waters probably contributes to the upward migration of metals and the development of an enriched band of Fe, Mn and other trace metals in the sediment column. The band of Fe and Mn may reduce the concentration of trace metals in the water column (Sigg, 1987). The bulk of the water which moves from the lake into the aquifer during the summer \"\"low flow\"\" period leaves Lake Coeur d'Alene as underflow. The area through which most water moves is probably within 300 feet (90 m) of the shore, where fine, laminated lake bottom sediments are lacking. This zone is probably well oxygenated for most of the year. Analyses from four monitoring wells at the surface water-groundwater interface reveal that metal concentrations are elevated in groundwater. Concentrations of Fe and Mn exceeded EPA SMCLs in all four wells. Three wells exceeded EPA MCLs for selenium. Well AIP-2 exceeded EPA MCLs for As, Cd and Ph. Clay samples from the well were highly enriched in As, Co and Cu, but only slightly above average background concentrations in Fe, Mn, Zn, U, and Th. The concentrations of Pb, Ni, Sr, V, and Cr in clays were slightly below average background concentrations. Metal migration into the aquifer does not appear to be attenuated by ionic adsorption onto clay materials. Eutrophication may have positive benefits for metal removal from the water column, as algae and Mn adsorb and precipitate trace metals. This benefit may be offset by the reducing conditions and elevated pH which result from aphotic biological activity in the hypolimnion.", "collection": "Coeur d'Alene Basin", "series": "Water for Idaho", "contributors": "Idaho Water Resources Research Institute; IWRRI; University of Idaho Department of Geology and Geological Engineering", "publisher": "Idaho Water Resources Research Institute, University of Idaho", "contributing-institution": "University of Idaho", "source": "Idaho Water Resources Research Institute, University of Idaho", "identifier": "IWRRI Number 199303", "language": "eng", "rights": "In copyright, educational use permitted.

Additional sampling included unpolluted portions of Coeur d'Alene Lake from December, 1969, to November, 1970, and the unaffected St. Joe River during the summers of 1969-70.

Although no water devoid of dissolved oxygen have been measured, 2-4 mg/1 have been measured in the southern portion of the lake. Phytoplankton productivity measurements and bottom organism identification and enumeration have shown that the lake functions at several trophic levels, meso-eutrophic to eutrophic in the southern portion, mesotrophic in the immediate area of the Coeur d'Alene River and oligotrophic in the northern portions. High metal concentrations (1000-7000 mg/kg Zn) in the bottom sediment of the middle and northern portions of the lake did not appear to substantially affect distribution of benthic chironomids or ogliochaetes. Lake sediment cores taken across the delta region of the Coeur d'Alene River penetrated through the region of high metallic concentration and allowed an average sediment deposition rate to be calculated. Algal toxicity tests showed the amount of Zn normally present in the Coeur d'Alene River and Spokane River to be inhibitory to the algal test organism Selanastrum capricornutum. The water quality of the Spokane River was shown to be of good to excellent quality in all parameters tested except for high metallic content, especially Zn. Activation and atomic absorption analysis of metallic content in the tissues of the organisms populating the Spokane River indicated that the algae were the prime concetrators of Zn, Cd, Pb, Hg, Fe, and Mn. Algae and detritus consumers such as the larvae of caddisfly Hydropsyche and the nymphs of the mayfly Baetis reflected high metallic concentrations. Most higher aquatic plants showed relatively lower concentrations. Analysis of fish tissues showed considerably less concentration of metals than the aquatic plants, insects or algae. However, Zn was measured at concentrations of 80-200 mg/kg in liver tissues of several species of fishes. Fillet tissues generally contained less than one quarter of these amounts.

Lake bed sediments in Killarney Lake were sampled at three separate localities using a piston core sampler operated from a raft. The cores collected 3.6 m and 3.5 m of lake bottom sediments from the north and south ends of the lake, respectively, and 6.4 m of sediments from the center of the lake. Lake bed sediments were also sampled to a depth of 59 em using a freezer box sampler.

The area also encompasses some of the foremost pollution problems in Idaho. The primary problems of environmental concern in this area today are the operating and abandoned tailings piles scattered throughout the district, the huge quantities of mine wastes accumulated along the streams, and the acid mine drainage from existing mines in the district. From previous studies, it is known that mine wastes containing iron sulfide (pyrite) in this area are capable of producing acid waters under oxidizing conditions. The redox status of groundwater is an important factor in determining the degree of acid water formation and subsequent leaching of metals from mine tailings and ore bodies in this mining area. A new approach for measurement of the redox status of groundwater involving analysis of water samples for concentrations of two arsenic species, As(V) and As(III), has been studied in this project. Based on thermodynamic equilibrium considerations, the apparent redox conditions can be evaluated from measured ratios of As(V)/As(III) in water. A simple solvent extraction method has been developed for the separation of arsenic species in mine waters using ammonium pyrrolidinedthiocarbamate (APDTC) as a chelating agent. The APDTC extraction method combined with neutron activation technique provides a very sensitive method for determining arsenic species in natural water systems. A detection limit of 0.1 ppb for the arsenic species in natural waters can be easily achieved using this method. This analytical method for arsenic speciation study is in the process of being published by ANALYTICAL CHEMISTRY. groundwater samples were collected from a major lead-zinc mine (the Bunker Hill Mine) and from other locations of the Coeur d'Alene Mining District to study the relationships between the arsenic species and other water quality data. The As(V)/As(III) ratios in ground waters collected from the Bunker Hill Mine were found to vary by more than two orders of magnitude indicating a wide range of redox conditions existing in the mine. The quality of groundwater in the mine is strongly correlated with the ratio of As(V)/As(III) found in the system. Good quality waters were generally associated with low ratios (<1) of As(V)/As(III). The ratio of the arsenic species and the concentrations of dissolved metals in the mine waters varied considerably with time. During the spring run-off, very high As(V)/As(III) ratios were observed in some poor quality waters presumably due to leaching of oxidized ores and mine wastes in certain locations of the upper levels of the mine. In the late summer, the ratio of As(V)/As(III) decreased as the system became more anaerobic and the water quality showed significant improvement correspondingly.

The Middle Fork, the original ''river of no return'', is born at the confluence of Marsh and Bear Valley Creeks: some twenty miles northeast of Stanley, and flows northward for about 100 miles through one of America's deepest gorges to join the min stem of the Salmon Below Shoup. It is a fast-flowing stream with numerous rapids and falls. Stretches of relative calm, however, can ''ease one to sleep'' before the next series of rapids greets the-unsuspecting floater. The lower 80 miles of the river is part of the Idaho Primitive Area. The fast-flowing, relatively pure and primitive characteristics of the river has nude it a national attraction for recreationists . River runners, hunters, fishermen, sightseers, and backpackers commonly confront the rugged confines of the area during the short summer season when snow packs allow access. Until the mid 1940's, only a limited number of hunters, prospectors, trappers, and fishermen used the area. In 1959, the Forest Service constructed a road to the upper reaches of the river that opened the area up and allowed a substantial increase in recreational use. For example, between 1962 and 1971 the number of Middle Fork floaters increased more than five times. The large increase in recreational use on the Middle Fork has helped generate considerable concern on the part of the Forest Service regarding the impact of this use on the environment of the area. Should use be limited? If so, when, how, and why? In an effort to provide some insight into these matters a study was initiated in 1970 to determine the recreational carrying capacity of the Middle Fork.

The timber resource in the Salmon River basin was inventoried and evaluated. Based on the information gathered it was concluded that classification of the river would have little effect on the timber industry in the area. The methodology developed around general steps to take in evaluating the timber resource in relation to the Wild and Scenic Rivers System. It was suggested that once it was decided that the river qualified for the System, the researcher suggest various classification schemes for the river. Then rapid, unrefined estimates be made of the amount and value of the affected timber resource. A market base should be selected and the evaluation done on a sustained yield basis. More refined estimates can be made at a later time if warranted. Also discussed were factors involving forestry and system rivers such as selection of interest rate and a land value base. It was determined that the main ties between forestry and system rivers related mainly to transportation, water quality, water quantity, and aesthetics. Harvest types and techniques and their relation to system rivers was discussed, and an interpretation of the Act and guidelines in relation to system rivers was presented.

The area of the basin is about 58 square miles. The principal water users, City of Moscow and University of Idaho, depend exclusively on groundwater obtained from wells that reach three zones of artesian aquifers in the basalt flows and sedimentary interbeds of the Columbia River Group of Miocene age. The three artesian zones are designated the upper, middle, and Bower artesian zones, The Columbia River Group is overlain by surficial sediments in which water generally occurs under water-table conditions, The Columbia River Group is underlain by a basement of crystalline rocks of pre-Tertiary age that also crops out beyond the limits of the basalt and forms the mountains that rim the basin on three sides. Where exposed at the surface, the crystalline basement contains water under water-table conditions. Neither the surficial sediments nor the crystalline basement will yield large amounts of water; the rocks of the Columbia River Group are the only source of water for public supplies. All groundwater originates as precipitation that falls within the borders of Moscow basin; natural discharge of groundwater is by underflow to the west. Prior to 1960, the entire public supply was obtained from wells reaching the upper artesian zone. The quality of water was unsatisfactory because of excessive amounts of iron and moderate hardness. Between 1960 and 1965, wells were drilled into the middle and lower artesian zones, and by 1965, nearly all water pumped for public supplies was obtained from the middle and lower artesian zones. The waters from the middle and lower artesian zones contain only moderate amounts of iron and are relatively soft. In 1896, water levels In wells in the upper artesian zone were at or slightly above land surface but declined continuously thereafter and, by 1968, static levels were nearly 120 feet below the surface in the vicinity of the City of Moscow wells. This decline led to suggestions that groundwater recharge in Moscow basin was insufficient to balance pumpage. Following the phasing out of heavy pumpage of the upper artesian zone in 1960-1965, water levels rose and recovered to within 65 feet of the surface in 1969. In our studies, two lines of investigation indicate that pumpage was not in excess of recharge during the period 1896-1960. We analyzed the pumpage and water level records of the public supply wells, using a mathematical model aquifer that utilizes the theory of image wells and assumes that there is no recharge to the basin. The results indicate that the decline of water levels in the upper artesian zone was actually much less than it would have been if pumpage was greatly in excess of recharge. We also studied the long-term records of water level fluctuations in observation wells in the basin. The water table in the surficial aquifers remained stable during the time that the water levels in the upper artesian zone declined. We attributed the decline in the water levels in the upper artesian zone to barrier boundary effects rather than to lack of recharge. The results of our studies support the views of previous workers who estimate groundwater recharge to the basin by use of the equation of hydrologic equilibrium. All such estimates indicate that recharge is in excess of pumpage sufficient to meet the demands of the basin through the year 2000, We also used our no-recharge mathematical model aquifers to estimate the total water in groundwater storage in Moscow basin and to predict the decline in water levels that would occur by the year 2000. Although these figures are based on an assumption that we have rejected--no recharge to the basin--they do represent the smallest amount of water and the largest amount of drawdown to be expected. The study indicates that the middle and lower artesian zones would meet the anticipated 1965-2000 demand of 50.1 billion gallons and still have as much as 299.4 billion gallons remaining in storage in the year 2000. Water levels would b e from 50 t o 80 feet lower in 2908 than they were in 1965. This study indicates that groundwater can supply the anticipated needs of Moscow basin well into the 21st century regardless of whether the water is derived from groundwater storage or from recharge. If need for water should exceed natural recharge at some time in the future, artificial recharge utilizing water from sources in and near Moscow basin could furnish more than 1 billion gallons of additional water annually. During a normal year, spring runoff from intermittent streams in the Palouse Range can provide about 300 million gallons over a 90 day period during February through May. The Moscow Wastewater Treatment Plant now discharges about 300 million gallons annually; the discharge should increase to about 1 billion gallons by the year 2000. The effluent could be further treated, then recycled by artificial recharge. Mathematical model studies show that the existing wells in the upper artesian zone can accept artificial recharge at rates of 1000 to 2000 gpm for as many as 100 consecutive days without the cone of impression reaching the surface. Cost of artificial recharge probably is less than the cost of long-distance importation of water. The waters of the surficial aquifers are relatively soft, averaging 87 ppm hardness as CaC03, and are relatively low in dissolved solids, averaging 127 ppm. As the waters move into the upper artesian zone, average hardness increases to 135 ppm and average dissolved solids increases to 190 ppm., probably as the result of solution of magnesium from magnesium-rich minerals in the basalts . As the waters move through the middle artesian zone and into the lower artesian zone, average hardness decreases to 84 ppm, but average dissolved solids increases to 286 ppm,; the decrease in hardness probably is the result of base exchange of sodium for calcium. Calcium and bicarbonate are the dominant ions in most of the ground waters of Moscow basin, but calcium and sulfate or sodium plus calcium and bicarbonate are the dominate ions in a few of the waters. Excessive amounts of iron are moderately common in waters from the surficial aquifers and very common in waters from the upper artesian zone. The iron originates in high-iron clay deposits in the surficial aquifers on the outer margin of the recharge area of the artesian aquifers. The high-iron waters move laterally from the clay deposits into the upper artesian zone. Waters from the middle and lower artesian zones contained only moderate amounts of iron when the aquifers were first placed into use. Continued pumpage could induce the high-iron waters to move into the middle and lower artesian zones. Silica also is somewhat high for ground waters and the origin of the silica probably is related to the origin of the iron. Some of the waters in the surficial aquifers contain relatively high amounts of nitrates and chlorides that indicate possible contamination from septic tanks, fertilizers, and barn-yard wastes .", "contributors": "Idaho Water Resources Research Institute; IWRRI", "publisher": "Idaho Bureau of Mines and Geology", "contributing-institution": "University of Idaho", "source": "Idaho Bureau of Mines and Geology", "identifier": "IWRRI Number 197212", "language": "eng", "rights": "In copyright, educational use permitted.

As water temperatures declined juvenile chinook left stream channels with gravel or shale substrates or moved into available hiding spaces in stream channels with rock and rubble substrate . Fish initially emigrated as temperatures declined below 10 C. I believe the number of emigrants reflects the holding capacity of the substrate and the density of the fish population.

Through the use of these tools, problems can be approached where the solutions at discrete points within the field of interest are sufficient. In this study a finite-element, planar-flow model was applied to a groundwater basin in southern Idaho, using a program developed by Dr. R. L. Taylor of the University of California at Berkeley. The area studied is an intermontane valley in Carnas and Elmore counties, Idaho, and consists of a prairie of valley-fill material that partially fills a valley about 30 miles long and 8-10 miles wide. The valley sides and surrounding areas are composed mainly of igneous and volcanic rocks that are relatively impermeable. The basement rock beneath the valley floor is assumed to be of the same material as the sides . The groundwater system consists of a shallow water table aquifer, a clay unit and 2 artesian aquifers separated by relatively impermeable silty clay. The model program is fitted to the geologic and hydrologic conditions of the area. A finite-element mesh is developed corresponding to a geologic section parallel to the valley axis. Input parameters to the model program are annual precipitation, permeabilities of the various units, boundaries and the geometric positions of positions of the mesh nodes with reference to a spatial coordinate system. The program computes head, potential, flow velocities in 2 directions normal to each other, resultant flow velocity and resultant flow direction with respect to the coordinate system, for each element in the mesh. The model seems to give an adequate representation of the groundwater system of the basin, based on comparison of computed hydraulic heads with actual measurements of water levels and artesian heads. Flow quantities are computed for underflow at the output end of the section, using average annual precipitation as input. Underflow is also computed for simulated situations of 3 and 6 inches more than and less than average annual precipitation. Changes in underflow equivalent to 4-0.03 and -0.05 feet of water input indicate that the artesian aquifers are essentially insulated from changes in annual precipitation in any given year. This type model should have practical use not only for describing a flow system but also for simulating past, future and/or locally changed conditions.", "contributors": "Idaho Water Resources Research Institute; IWRRI", "publisher": "Idaho Water Resources Research Institute, University of Idaho", "contributing-institution": "University of Idaho", "source": "Idaho Water Resources Research Institute, University of Idaho", "identifier": "IWRRI Number 197221", "language": "eng", "rights": "In copyright, educational use permitted.

The Blackfoot River model is steady state, deterministic and one dimensional. It has been calibrated and verified and has been found satisfactory under the limitations of the observed data and the complexity of the ecosystem. The technique of model application has been illustrated with the help of arbitrary waste discharges at selected points in the basin. Two hypothetical combinations of inputs have been assumed. The effects of these discharges on the water quality of the streams have been simulated by the model. The model can be useful in deciding the management policies for phosphate mining and processing operations in order to mitigate or avoid their adverse impacts on water quality of the streams. The model can be adapted to the planning of these operations as well as to the planning and management of other human activities in the area with regard to their water quality impacts.

The proposed method first extracts the trivalent As(III) and Sb(III) as pyrrolidinecarbodithioate (PCDT) complexes into chloroform, followed by a nitric acid back-extraction to recover the elements. Arsenic and Sb in the acid solution are determined by neutron activation analysis (NAA). The pentavalent species, As(V) and Sb(V), are reduced to the trivalent state using potassium iodide and sodium thiosulfate and then are extracted with PCDT for NAA. The two-step preconcentration procedure provides a large enrichment factor, eliminates the interfering matrix species, and extends the useful working range of NAA for As and Sb. The extraction method has also been applied to the determination of low levels of As and Sb in biological samples by NAA. The speciation method has been used to evaluate the distribution of As(III) and As(V) and its relation to other water quality parameters in the groundwater system of a major lead-zinc mine in the Coeur d'Alene Mining District of northern Idaho. It is known that mine wastes containing pyrite (FeS2) are capable of producing acid waters under oxidizing conditions, and the redox status of groundwater is an important factor in determining the degree of acid water formation and subsequent leaching of metals from mine tailings and ore bodies in this mining area. The results obtained from this study show that the relative concentrations of the arsenic redox pair are correlated with the quality of the mine waters studied and the ratio of As(V)/As(III) has the potential to be a redox indicator for groundwater systems. The river sediments of the South Fork and the Main Stem of the Coeur d'Alene River are contaminated with As, Sb, and other heavy metals from past mining activities. The distribution of As and Sb species in the river waters has been studied. Trivalent As(III) is the predominant form of arsenic in the South Fork and the Main Stem, whereas the unpolluted North Fork generally has a higher concentration of As(V). The major Sb species in the three branches of the river is Sb(V). Mobilization of sediment As and Sb during sediHent-water interactions has been investigated using laboratory leaching experiments. The releases of As and Sb are related to the free iron oxides and free manganese oxides of the sediments. The effects of the contaminated sediments on the water quality, with respect to As and Sb, of the creeks surrounding the Blackbird area in east-central Idaho have also been investigated. The pentavalent As(V) and Sb(V) are the major species observed in the creek waters. The field observations are consistent with the leaching experiments performed in the laboratory.

Previous surveys of (CDAL) sediment have suggested the majority of the metals are bound in an oxide phase, and if true, contaminated water may result if anoxic conditions occur in the water column. In contrast, data from this study indicate that the majority of the iron and trace elements are bound in a sulfidic phase. Examination of the sediment pore waters shows iron and trace element concentrations to be more than federal drinking water standards. Strongly reducing conditions and an abundant microbial community are also present, indicating that reactions that occur under reducing conditions are predominant in CDAL sediments. In particular, sulfate-reducing bacteria (SRB) are abundant in CDAL sediments. Isolates of native SRB have the ability to form sulfides from soluble metal. In such conditions, metal solubility is low. indicating that SRB may act to mitigate the effects of metal contamination in CDAL. Arsenic shows some different trends as compared with other trace elements. Arsenic solubility is highest in redox potential between the ferric to ferrous couple and the sulfate to sulfide couple. As (III) is not sorbed as well to sediment components, and hence formation of reduced forms of arsenic may encourage arsenic mobilization in anoxic sediments. Bacterial transformations of arsenic have recently been shown to occur in sediments. In this study, arsenic reducing organisms were found to be less abundant than SRB, but still numerous. Additions of soluble As (V) to sediment microcosms were reduced to As (III). This reduction was stimulated by organic acids, and was inhibited by a respiratory inhibitor of SRB. These results suggest that SRB can form metal sulfides, and also mobilize arsenic by creating a reduced mobile form.", "collection": "Coeur d'Alene Basin", "contributors": "Idaho Water Resources Research Institute; IWRRI", "publisher": "University of Idaho", "contributing-institution": "University of Idaho", "source": "University of Idaho", "language": "eng", "rights": "In copyright, educational use permitted.

The four habitat types differed significantly in habitat characteristics based on Rapid Bioassessment Protocols (RBP) scores (F=5.73, P<0.001). All four habitat types scored poor or marginal in substrate/available cover, pool variability, sediment deposition, and riparian zone width. Relative fish abundance as measured by CPUE at stabilized (RR and RR V) shorelines was consistently higher than at unstabilized (FB and V) shorelines among all seasons. Relative fish abundance was not significantly different between stabilized and unstabilized habitat types for gillnetting (F= 1. 9 5, P=0.167), but was significantly higher at stabilized than unstabilized habitats for electrofishing (F=5.66, P=0.020). Differences in species diversity were only evident between sections, not among habitat types or seasons. Fish community differences were apparent among habitat types as well as between sections and among seasons. Brown bullhead Ameirus nebulosus, northern pike Esox lucius, and pumpkinseed Lepomis gibbosus were captured in significantly higher numbers at stabilized than unstabilized sites and longnose suckers Catostomus catostomus were captured in greater numbers at unstabilized than stabilized sites. Water temperature and spawn timing influenced fish abundance and composition in spring. Large diameter riprap supported a higher abundance of fish than did smaller diameter riprap. Overall, stabilized shorelines on the lower Coeur d'Alene River were not found to be adversely affecting overall fish relative abundance, diversity, and species composition under the existing conditions of a low percentage of banks stabilized with riprap (2.5%). Instead, stabilized shorelines provided beneficial habitat in a river system with low quality and diversity of available habitats. This result should not be predicted, however, to apply as increasingly high percentages of the river bank are stabilized, and loss of river function occurs. Data from the above sampling were also analyzed to assess possible impact of piscivores (smallmouth bass Micropterus dolomieui, northern pikeminnow Ptychocheilus oregonensis, and northern pike) on native salmonids, especially Westslope cutthroat trout Oncoryhynchus clarki lewisi. The objectives were to 1) evaluate and quantify salmonid use of stabilized and unstabilized shoreline habitats by season and river section, 2) evaluate and quantify piscivorous species use of stabilized and unstabilized shoreline habitat by season and river section, and 3) determine if an overlap exists between salmonid and piscivore use of stabilized and unstabilized shoreline habitats by season and river section. In all, 81 salmonids were captured, or 2% of the total fish catch. Salmonid catch in the lower river was greatest during spring when water temperatures were low and juveniles were outmigrating to Lake Coeur d'Alene. No significant differences in salmonid catch were evident between stabilized and unstabilized habitats (x2=0.064, P=0.800), though juvenile westslope cutthroat trout showed some affinity for stabilize areas with I 0 out of 12 individuals captured at these sites. In all, 670 piscivores were captured, or 19% of the total fish catch. Piscivore catch was significantly lower in spring, when salmonid numbers were highest, than in fall and summer, when salmonid numbers were lowest (x2=17.465, P<O.OOl). Overall, piscivores were not captured in significantly different numbers at stabilized and unstabilized habitats (x2=0.243, P=0.622); however, northern pike (N=22) were captured in significantly higher numbers at stabilized habitats. The overall effects of habitat type on salmonid and piscivore overlap were not clear. Based on the data available, season seems more important than habitat in affecting salmonid and piscivore impacts. Specific studies are outlined that need to be conducted for a clearer understanding of the relation between salmonids and potential predation from piscivores in the lower river. In comparison of catches between the two gears (gillnetting and electro fishing), species composition (x2=831.46, P<O.OO 1) and length selectivity (t=3 7 .86, P<O.OO 1) were significantly different. Electro fishing captured a greater numbers of individuals (N=2,915) than gillnetting (N=596), but individuals were much smaller for electrofishing (mean length 96 mm) than for gillnetting (mean length 331 mm). Gillnets more readily captured longnose suckers and largescale suckers Catostomus macrocheilus (50% of total catch), whereas electro fishing captured larger numbers of yellow perch Perea flavescens and pumpkinseed (54% of total catch).

Mine wastes from zinc, silver and lead mines were discharged into the river and have been deposited in thicknesses up to seven feet over a large area of the Flats causing significant water quality degradation in the underlying aquifer. Water levels and water quality were monitored in ten pairs of piezometers (10 shallow and 10 deep) through two spring recharge events to study the effects of hydrology on water quality. Heavy metal concentrations measured in the shallow wells were consistently higher than those measured in the deep wells. Despite a significant difference in water quality between the shallow and deep sets of piezometers, dissolved constituents change congruently in the deep and shallow piezometers. Zinc concentrations in the shallow wells varied widely across the Flats. Zinc concentrations could be correlated with depth in the deep piezometers implying the existence of a downward concentration gradient away from the wastes above the aquifer. A linear relation between zinc and cadmium concentrations and to a lesser extent between zinc and lead concentrations supports the use of zinc as an indicator of contamination by the mine waste. While overall zinc concentration correlates positively with electrical conductivity collectively, well by well correlation is not consistent. Zinc concentration correlates negatively with pH in the deep wells but this correlation is not conclusive in the shallow wells. Variations in zinc concentrations are associated with antecedent precipitation and therefore recharge more than with water level rise. Therefore remediation efforts should focus on decreasing recharge. A conceptual model of heavy metal influx has been established consisting of three stratigraphic layers. Infiltrating groundwater passes through the first layer and dissolves heavy metal ions. The heavy metal bearing water then moves downward through the second layer and mixes with horizontally migrating groundwater of lower zinc concentration in the third layer.

Possible environmental management plans in the region may include dredging and bank stability projects. Two different studies were initiated to look at potential contaminant release from proposed dredging of Lake CDA and from natural flooding events in the MSCDR and SFCDR. In the first study, an ex-situ experiment was conducted to determine how dredging releases heavy metals from contaminated lake sediments. The procedure used is as follows: 1) pore water total metal concentration, 2) total metal abundance in the organic, amorphous, crystalline and sulfidic fractions of the solid phase, 3) simulated dredging while measuring pH, Eh, and contaminant release over time, and 4) comparison of experimental data with results predicted from the MINTEQA2 speciation program. To simulate dredging operations, cores taken by gravity drilling were placed into a reaction vessel and mixed while being oxygenated for 800 hours. During the 800 h, solution As and Pb concentrations were found to be higher (0.0838 and 0.57 ppm, respectively) than the maximum contaminant levels allowed for drinking water and therefore would be detrimental to water quality within the lake. Zinc contaminant levels are of concern because they remain consistently high throughout the dredging simulation (8.3 ppm). The sediments remaining from the two dredging trials were also analyzed by selective dissolution analysis; partitioning of contaminants after dredging shifted from the organic fraction to the amorphous and crystalline metal-oxide fraction. The results suggest that management efforts that include dredging could have short-term impact on water quality in the Coeur d'Alene Basin. An environmental remediation plan is necessary to control the release of heavy metals as flooding occurs in this region. In order to address the environmental ramifications of flooding, water quality in the river system was assessed, contaminates in the riverbank sediments were geochemically phase partitioned, and their release were measured under simulated laboratory flooding experiments. To simulate flooding experiments, 18 columns were constructed allowing the sediment-water interface to be monitored for pH, Eh and dissolved concentrations of As, Fe, Mn, Pb, and Zn. These columns were subjected to two flooding events. The first event involved the addition of N2(g) and 0 2(g> purged river water to the columns and the second event also had a nutrient source (D-glucose) added to the solution in the columns. During the first event Zn was released at an average concentration of 10.41 mg/L into solution from sediment taken along the MSCDR at Cataldo, ID. For the second event, nutrient loading stimulated microbial activity which in turn increased contaminant levels drastically at all three sites; mean values of trace element contaminants from the three sites are As= 1.54, Pb = 7.57, and Zn = 79.29 mg/L. The release of contaminates due to flooding is degrading water quality in the river system and proving to be extremely detrimental to the aquatic biota. Results indicate that sediments currently situated in the riverbanks are releasing contaminants into the river system as flooding occurs and a remediation plan is necessary to eliminate this problem. In particular, extreme precaution must be used in the region to limit nutrient additions into the river system.", "collection": "Coeur d'Alene Basin", "contributors": "Idaho Water Resources Research Institute; IWRRI", "publisher": "University of Idaho", "contributing-institution": "University of Idaho", "source": "University of Idaho", "language": "eng", "rights": "In copyright, educational use permitted.

Mine wastes were deposited on the flood plain or in the channel of the South Fork of the Coeur d'Alene River. In the early 1900s, a series of dams were built across the South Fork of the Coeur d'Alene River at the western end of Smelterville Flats in an attempt to control the downstream transport of mine wastes. Mine wastes and other sediments were deposited behind this dam. The site, known as Smelterville Flats, is the largest uncontrolled deposit of mining wastes that remains in the South Fork of the Coeur d'Alene River Valley. Water levels and water quality samples were collected from existing monitoring wells within the Smelterville Flats study area. A more intensive study was conducted on a small sub-area of the Smelterville Flats study area known as the Bureau of Land Management (BLM) sub-area. Ten sets of piezometers were installed to monitor water quality and water levels in the upper aquifer beneath Smelterville Flats in the BLM sub-area. A pumping well and observation wells were installed in the BLM sub-area in order to conduct a pumping test in the upper aquifer to determine aquifer coefficients. groundwater level gradients in the study area indicate that the groundwater flow direction is from east to west, following the general gradient of the valley of the South Fork of the Coeur d'Alene River. Water levels also indicate that the South Fork of the Coeur d'Alene River is a losing stream in the east end of the study area and a gaining stream in the west end of the study area. Shallower monitoring wells in the upper aquifer within the BLM sub-area consistently had higher concentration of ions associated with mining wastes than deeper monitoring wells installed in the same aquifer at the same location. Oxidation of the mine wastes may occur in the unsaturated zone in the presence of oxygen, or in the presence of oxygen and water if the film of water is thin enough to allow the diffusion of oxygen to the reaction sites. The thin layer of water surrounding the wastes may become a concentrated solution of soluble reaction products. Infiltration of precipitation, and rises in groundwater levels flush and transport the soluble reaction products from the reaction sites on the wastes into the shallow groundwater system. The oxidation products are removed from the reaction sites, thereby producing fresh reaction sites for the next influx of oxygen. The reaction products may then be transported by the groundwater flow system, which ultimately discharges to the South Fork of the Coeur d'Alene River at the western end of Smelterville Flats. Based on the data collected, potential mitigative measures were evaluated and analyzed in order to minimize the adverse long-term effects of mine waste on the groundwater and surface water systems. Potential mitigative measures that are evaluated include treatment of the shallow aquifer water, elimination or reduction of groundwater flow through the shallow aquifer, removal of the major sources of metal ions, and no action. The continuation of research to identify or develop a mechanism to extract marketable metals from the wastes on Smelterville Flats appears to constitute the most appropriate course of action.", "collection": "Coeur d'Alene Basin", "contributors": "Idaho Water Resources Research Institute; IWRRI", "publisher": "University of Idaho", "contributing-institution": "University of Idaho", "source": "University of Idaho", "language": "eng", "rights": "In copyright, educational use permitted.

Along this reach, cadmium, lead, and zinc concentrations in soil and pore water are known to be elevated as a result of historic mining activity within the Coeur d'Alene watershed. In order to identify sources of heavy metals release to the river, a conceptual hydrogeological model and metals loading analyses were completed along the subject reach. Based on the results of the hydrogeologic investigation completed at 23 groundwater and 16 surface water sites, the dredge materials constitute a perched water table system that show little, if any, connection to the Coeur d'Alene River. Based on the results of an approximate loading analysis (using USGS gaged flows and water sampling) on six sections along the reach, no significant increases or decreases in dissolved cadmium, lead, or zinc loadings were identified. These results indicate that no significant inflows of impacted groundwater containing high levels of heavy metals can be identified along the Cataldo Mission Flats reach. From a remedial perspective, this suggests that large-scale excavation of the dredged materials along this reach is not necessary and that attention should be focused on remediation and stabilization of impacted and erodible material, which has the potential to be suspended during high flow times. Based on these results, it is recommended that in areas where erodible and impacted dredged materials have been identified, which are not well vegetated, these materials should be stabilized by armoring or using heavy metals-tolerant vegetation. Where a riparian environment is established over impacted dredge materials, these bank areas should be stabilized so as to promote continual development of the riparian zone and minimize resuspension of the sediments and destruction of the riparian zone during high flow events. An additional recommendation is that a similar multi-location loading study of dissolved and suspended metals be repeated during high flow when bank sediments are being resuspended by erosion to identify specific locations of sediment loading.", "collection": "Coeur d'Alene Basin", "contributors": "Idaho Water Resources Research Institute; IWRRI", "publisher": "University of Idaho", "contributing-institution": "University of Idaho", "source": "University of Idaho", "language": "eng", "rights": "In copyright, educational use permitted.

Bureau of Land Management (BLM). Smelterville Flats lies within the Bunker Hill Superfund Site which is located along the South Fork of the Coeur d'Alene River in northern Idaho. The Flats have been the repository of over 100 years of uncontrolled mine waste dumping. These mine wastes degrade the shallow groundwater and are being studied to evaluate possible mitigative measures. Natural recharge events such as spring snowmelt or locally intense rainstorms are observed to influence temporal fluctuations in groundwater quality and groundwater levels observed at the BLM site. These recharge events must be considered in light of the metals content of the mine waste, the local fluvial sediment stratigraphy, and the local infiltration history. These factors control the residence time of any particular pulse of infiltrating moisture within the mine wastes and governs the impact of this infiltration on groundwater quality and groundwater levels. Three months of artificial recharge conducted on the BLM site made no observable impact on measured groundwater levels or groundwater chemistry. The spatial patterns of groundwater quality in this study area are controlled by the geology, hydraulic conductivity, and metals content of mine waste in the neighborhood of the piezometer, as well as the local sedimentary stratigraphy. Poor quality shallow groundwater samples can be associated with flotation slimes containing relatively high amounts of metals and having a relatively low hydraulic conductivity. The mine wastes can be separated physically, statistically, and geochemically into jig tailings and flotation slimes. The jig tailings are oxidized in appearance, sandy, and typically contain about one-half the zinc content of the flotation slimes. The flotation slimes appear black to dark gray, and are composed of silt to clay sized particles. The spatial distribution of the mine wastes within the BLM portion of Smelterville Flats is controlled by fluvial and lacustrine depositional environments, by the morphology of the pre-mining fluvial plain, by the production histories of the mine and mill wastes, and by subsequent surficial weathering and fluvial reworking. Consideration of the impact of natural recharge events should be included in the design of extractive mitigative efforts at Smelterville Flats.

The Project provides a mechanism for the coordination of various programs and activities designed to achieve these goals. The Coeur d'Alene Basin Restoration Project Framework is a roadmap for environmental protection and restoration of the basin. A task outlined in the framework, is the identification of attainable uses of stream segments in the basin. This task is the primary objective of this study. Recovery of beneficial uses of water bodies impacted by past land use activities is best assessed by in-stream water quality monitoring with results compared to specific water quality criteria. The beneficial uses of any given water body determine a set of water quality criteria necessary to support those beneficial uses. For this reason, beneficial use attainability assessments were conducted on a wide range of stream segments in the basin. Other objectives of the Coeur d'Alene Basin use attainability analysis are to: refine existing chemical water quality criteria and determine physical habitat and biological criteria necessary to support specific beneficial uses; and assess the status of beneficial uses of waters in the basin. Essentially, beneficial support status as determined by the current study provides a qualitative indication of the current support level of uses deemed attainable for a given waterbody; refined water quality criteria quantitatively identify the desired future condition necessary to achieve full support of beneficial uses. Future monitoring of beneficial use recovery will utilize quantitative water quality criteria to gauge restoration success. In meeting the study objectives, this study reviewed beneficial use designations currently incorporated in the Idaho Water Quality Standards. A total of 21 streams have use designations in the Lake Coeur d'Alene basin, of which 11 were verified. This study identifies the need to revise the remaining use designations to accurately reflect the actual attainable and existing uses. An additional 155 streams in the basin were assigned beneficial use classifications based on a structured scientific approach set forth in Idaho's standard use attainability protocol. This study documents the attainable and existing beneficial uses for a wide range of water bodies in the Lake Coeur d'Alene basin based on background information provided by cooperating agencies and field verification results from the IDEO 1992 field surveys. In addition, the status of beneficial uses (full support, partial support or non-support) in the basin is assessed. The information generated in the study provides the impetus for anticipated revisions and inclusions of use designations in the Idaho Water Quality Standards, which are necessary for protection and restoration of water quality in the basin.

In some areas the flood peaks were the second highest ever recorded and exceeded flows that have a 1% chance of occurring during any given year. The focus of this study was to expand the understanding of the influence of biological and physical processes and landscape patterns at the scale of watersheds and subbasins on the distribution, abundance and persistence of westslope cutthroat trout Oncorhynchus clarki lewisi. During the summer of 1996, I sampled 62 second and third order tributaries within the Coeur d'Alene River basin using a stratified random sampling design. Streams were divided into three reaches of equal length, and three sites within each reach were randomly chosen for single pass electrofishing. One of the nine sites in each stream was randomly selected for an estimate of absolute abundance using multiple pass electrofishing. Capture efficiency was estimated from the multiple pass sites using a maximum likelihood estimator. Mean capture efficiency was 68% and ranged from 23 to 100%. Single pass catches were adjusted using the average capture efficiency for the basin, and the adjusted catches were used to compute density estimates for all streams. All streams sampled contained westslope cutthroat trout, suggesting that local extinctions did not occur following the January 1996 flood. The mean stream density in 1996 for the entire basin was 0.057 fishlm2 and ranged from 0.001 to 0.219 fish. Estimated densities were highest in tributaries to the Main Coeur d'Alene River ( x = 0.083 ), followed by tributaries to the Upper Coeur d'Alene River ( x = 0.048 ), tributaries to Shoshone Creek ( x = 0.067) and tributaries to the North Fork Coeur d'Alene river ( x = 0.039 ). Mean densities for the Main Coeur d'Alene and North Fork Coeur d'Alene sub basins were not significantly different in 1996 than 1995 (p = 0.868 and p = 0.271 ). Mean densities in both the Upper Coeur d'Alene and Shoshone Creek sub basins were significantly lower in 1996 than 1995 (p = 0.063 and p = 0.008), but these differences can be accounted for by three streams in the Upper Coeur d'Alene drainage and one stream in the Shoshone Creek drainage. Densities in the North Fork Coeur d'Alene were nearly significantly different from densities in the Main Coeur d'Alene (p = 0.090) and Shoshone Creek (p = 0.1 08) in 1996, however, no other drainages showed significant differences in densities in 1996. Age-0 cutthroat trout were not found in any streams with wetted widths wider than 8 m. Logistic regression was used to model the probability of encountering cutthroat trout fry, and the best model used gradient to predict the probability of encountering age-0 cutthroat trout (p = 0.0005). Estimated density of westslope cutthroat trout was significantly related to large woody debris counts per 1000 m of channel, and cumulative equivalent clearcut acreage (R2 = 0.505, p = 0.004). Densities decreased with increased wetted width, increased with increased large woody debris count, and decreased with increased cumulative equivalent clearcut acreage. My results showed that cutthroat trout densities are better predicted by variables measured at the stream or watershed level than at the site or habitat type level. Cutthroat trout in the Coeur d'Alene River basin were able to persist following significant disturbance including disturbance due to land management activities, disturbance due to severe flooding, and the cumulative effects of both.", "collection": "Coeur d'Alene Basin", "contributors": "Idaho Water Resources Research Institute; IWRRI", "publisher": "University of Idaho", "contributing-institution": "University of Idaho", "source": "University of Idaho", "language": "eng", "rights": "In copyright, educational use permitted.

Recent environmental studies have generally demonstrated an improved condition in the Coeur d'Alene River, lateral lakes, and downstream Lake Coeur d' Alene since the early monitoring. We sampled largemouth bass (Hicropterus salmoides), northern pike (Esox lucius), black crappie (Pomoxis nigromaculatus), brown bullhead (Ictalurus nebulosus), and yellow perch (Perea flavescens) from Killarney Lake, a lateral lake on the Coeur d'Alene River in northern Idaho and analyzed edible flesh for concentrations of zinc, lead, mercury, cadmium, copper, and arsenic. Mean concentrations (n=lO) of zinc were highest in yellow perch (4.79 mg/kg -wet weight) and lowest in brown bullheads (2.95 mg/kg), considerably lower than the 45 mg/kg action level from the literature. Mean concentrations (n=10) of copper ranged from 0.265 mg/kg in black crappie to 0.31 mg/kg in yellow perch, northern pike and largemouth bass, also well below the recommended action level of 20 mg/kg. Mean concentrations (nlO) of lead ranged from 0.014 mgjkg in largemouth bass to 0.183 mg/kg in brown bullheads, compared to the 3.50 mg/kg action level. Mean concentrations (n10) of cadmium ranged from 0.018 to 0.04 mg/kg, highest in brown bullheads and lowest in northern pike. Action levels listed in the literature for cadmium were 0.07 mg/kg. Mean mercury concentrations ranged from 0.034 mg/kg in brown bullheads to 0.093 mg/kg in yellow perch, also less than the 1 mg/kg action level. Concentrations of arsenic were generally below detection limits (<0.04 mg/kg) for all species but varied considerably between two laboratories which conducted analysis on replicate tissue samples. Comparisons of all species of fishes with the metals tested resulted in significant increases in body content as a function of size in largemouth bass for copper and mercury in yellow perch and zinc in black crappie. Comparisons of fish flesh content with allowable human intakes resulted in estimation of a maximum allowable consumption of 3.1 kg/week of fish from Killarney lake. Tolerance limits calculated for the various flesh concentrations of metals indicated that we were 99% confident that 99% of the populations were at or below action levels for the species sampled for zinc, copper, and lead. Tolerance limits for cadmium in yellow perch and brown bullheads exceeded the recommended action limits, while those in northern pike and black crappie were at the action level. Based on our sample results from 10 fish, additional sampling is needed to adequately describe the distribution of lead in brown bullheads (N 50) and yellow perch (N 26) from Killarney lake. Differences in detection limits of heavy metals, differences in concentrations from the same fillet from two laboratories, and between-site variation all suggest a cautious approach to the interpretation of heavy metal analysis data from surface waters.", "collection": "Coeur d'Alene Basin", "contributors": "Idaho Water Resources Research Institute; IWRRI", "publisher": "Bureau of Land Management; University of Idaho", "contributing-institution": "University of Idaho", "source": "Bureau of Land Management; University of Idaho", "language": "eng", "rights": "In copyright, educational use permitted.

This report presents the results of a study of potential water quality problems from abandoned flotation tailing impoundments and offers specific reclamation plans designed to minimize water quality degradation. A summary of current reclamation technology is presented, followed by field studies of three abandoned impoundment sites. An inventory of all abandoned tailing impoundments in the South Fork basin was conducted. Based on the field studies and inventory of all sites, a number of factors important in site abandonment were identified and categorized as either physical, chemical, or esthetic. Classification of each site with respect to the identified factors was then possible. A general reclamation plan was drafted which deals with each of the identified factors important in site abandonment. Application of the general reclamation plan to each of the sites listed in the abandoned impoundment inventory ends the report. It is concluded that the major problems posed by the abandoned tailing impoundments are physical rather than chemical.

Contamination in these areas is often reported as total contaminant concentration per mass of soil, and assumes that the contaminants are homogenously distributed throughout the soil. However, pedogenesis causes distinct secondary mineral redistribution within soil profiles, and leads to selective partitioning of contaminants within the profile at macro (em) to sub-micron scales. This study examined the variability of redoximorphic features within a wetland, and contaminant enrichment in redoximorphic features relative to landscape position and water table height. Six distinct categories of Fe and Fe/Mn-rich cemented redoximorphic features were identified. The Fe and Fe/Mn-cemented redox features were found to have Cd and Pb concentrations up to four and six times greater in magnitude than soil averages. Iron and Fe/Mn-cemented redox features also had elevated levels of As and Zn. The Fe/Mn-cemented aggregates had the highest Mn concentrations (approximately 3.4%), were most common in the 1-2 mm size fraction, and contained the highest concentration of Pb (approximately 2.6%). Iron-cemented root channel linings and Fe-cemented aggregates had comparable concentrations of As, Cd, Mn, Pb, and S. Coarse sand aggregates and Fe/Mn-cemented aggregates had similar concentrations of Cd, Mn, P, and Zn. Iron-cemented aggregates and cemented root channel linings had physical similarities, while coarse sand aggregates and Fe/Mn-cemented aggregates also appeared similar. The Fe and Fe/Mn-cemented redox features were found primarily in the top 15 em of soil and decreased with soil depth. Results from this study show that pedogenesis in Coeur d'Alene wetland soils results in distinct redoximorphic features and non-homogeneous metal concentrations. Among these features are Fe and Mn - cemented aggregates that range in size from 1 to 2 mm in diameter. These aggregates have unique mineralogy and concentrate metals within the soils. Understanding contaminant partitioning and speciation in soils will allow for improved management and risk assessment of the contaminated soils.", "collection": "Coeur d'Alene Basin", "contributors": "Idaho Water Resources Research Institute; IWRRI", "publisher": "University of Idaho", "contributing-institution": "University of Idaho", "source": "University of Idaho", "language": "eng", "rights": "In copyright, educational use permitted.

In the early days, jig tailings containing sphalerite and other heavy metal sulfides were discharged directly into the South Fork Coeur D' Alene River resulting in the elimination of aquatic life. Over the past 20 years, water quality legislation and modern milling techniques have combined to reduce sediment load and eliminate point source pollution from mine and mill sites, thereby improving the water quality along the South Fork. However, ''background'' levels of metals continue to pose problems for aquatic life in the river. This project recorded 18 sampling stations along the South Fork and Main Stem of the Coeur D' Alene River over a six month period; these values are compared to the metal concentrations reported in historic data collected by Mink (1969) and the EPA (Environmental Protection Agency) (1972-1984). The sampling station at Cataldo on the Main Stem and the stations upstream of Wallace on the South Fork did not exhibit excessive concentrations of the elements analyzed. Zinc displayed the highest overall concentrations during the study period; it exceeded toxicity limits for the survival of aquatic life. Station 12, located downstream of Smelterville Flats, exhibited the highest consistent concentration of zinc along the river. The highest zinc concentrations of all occurred in March from overland runoff through tailings, from the smelter dust on the land surface mixed with runoff, from the Smelterville Flats aquifer, and in July from groundwater inflow. May displayed the lowest overall zinc concentration during the sampling period. Past EPA studies indicate that cadmium and lead, although declining in concentration, still exceed EPA toxicity limits for the survival of fish along the South Fork. Since 1980, zinc levels at Smelterville Flats exceeded EPA's standard drinking levels. Although still above chronic levels for aquatic life, zinc concentrations are on the decline. Zinc levels at Cataldo have declined steadily since 1976 and have not exceeded drinking standard limits. The 1988 data compared to Mink's data from 1969 at Cataldo on the Main Stem indicate somewhat of a decrease in zinc concentrations. Station 12 at Smelterville Flats is variable for 1969 and 1988; but the majority of the 1988 zinc concentrations are lower than Mink's data, particularly during July and August. EPA bioassays conducted in 1986 record a number of benthic insect species living along the South Fork; a good return of game fish downstream of the South Fork confluence has been detected in the Main Stem of the Coeur D' Alene River.

Water samples collected from 34 stations on the Coeur d'Alene River system over a sixteen-month period indicate zinc and cadmium concentrations above toxic limits for fish survival over much of the South Fork and Main Stem; with the exception of fluoride which is high at two stations during low flow, concentrations of most other elements are comparable to or slightly greater than concentrations observed in the North Fork. The water quality data indicate one major source for zinc, cadmium, and fluoride and one less easily identifiable source. High river stage also increases total mass of zinc transported in solution, which suggests a source during high flow in addition to present day mine waste disposal operations. Elimination of the high zinc and cadmium concentrations is considered to be essential to the complete recovery of the river. Basin-wide installation of settling ponds for mill wastes (not for all industrial wastes) by December 1968 has greatly improved the quality of water, particularly with respect to suspended solids. As a result, macrobenthic fauna recently have been discovered in the South Fork and a greater number of species found in the Main Stem, which indicate that the river is beginning to recover.

Section 304 (I) of the Water Quality Act of 1987 requires each state to list all stream segments that receive point source discharges of toxic pollutants and do not support appropriate beneficial uses even after effluent limitations are in place. In 1989 the U.S. Environmental Protection Agency (EPA) provided funding to the Idaho Division of Environmental Quality to assess the water quality and biotic integrity of the South Fork near Mullan, Idaho in Shoshone County. Water quality information was collected during the 1990 water year. The water chemistry and biological data were used to determine the support status of the beneficial uses and the relevance of the segment boundary listed in Idaho Water Quality Standards. Specific objectives of this study include the following: 1) determine point source and nonpoint source heavy metals contributions to the South Fork above the Morning District bridge near Mullan, Idaho; 2) determine the effect of heavy metals on aquatic life uses in the study reach; and 3) determine the relevance of the stream segment boundary between stream segments PB-130s and PB-140s. Metals loading to the South Fork above Mullan, Idaho was modest compared to other reaches within the drainage, as estimated by the 1989-1990 data. Nonpoint source additions were the primary source of heavy metals to the river above Mullan. Between 1989 and 1990 treated wastewater from Hecla's Lucky Friday mining operation generally contributed less than 3.0 % of the cadmium, copper and zinc load in the river. Lead contribution to the river from Hecla discharges were generally less than 9%, although low flow total lead contribution from pond 001 was estimated at 42% of the load at the lowest river station. Fish and benthic macroinvertebrate communities were assessed at all the river stations in the study area. Macroinvertebrate data analysis does not conclusively indicate impairment of the use at the sampling stations from point source additions. Fisheries data was insufficient to determine the effect of point source metals discharges on fish communities at the sampling sites. Due to equipment failures, proper fish collection procedures were not followed therefore, comparisons of population estimates between each sample station were unavailable. However, qualitative analysis of fisheries information do not suggest substantial differences in beneficial use support status throughout the study reach. Impairment of beneficial uses and/or water chemistry of a waterbody attributed to point source pollution discharges, should be demonstrated in order to warrant 304 (I) listing. The data do not support the 304 (I) listing of segment PB-130s since impairment of cold water biota is not apparent. In addition, water quality data indicate point source contributions of metals to the river in PB-130s are minor compared to nonpoint sources. Toxicological effects of metals on aquatic organisms (if any) in segment PB-130s cannot be attributed to point source additions within the scope of the current study design. The information generated in this study was also used to evaluate the appropriateness of the segment boundary location between segments PB-140S and PB-130s. The designated beneficial uses of segment PB-140s (lowermost) differ from the range of uses designated for segment PB-130S. The existence of such a boundary implies beneficial uses change and therefor water quality management changes at a given boundary. However, the observed appropriate beneficial uses do not change throughout the length of the study reach. The beneficial use of cold water biota and salmonid spawning are existing and attainable everywhere in the study reach. These data do not support placement of a segment boundary anywhere within the current study site. Reliable toxics criteria for cold water biota in the study site apparently are not available.

The abandonment of mine tailings piles may have detrimental effects on the water resource system in the immediate area by leaching of metals from the movement of precipitation through the pile material. This report presents the results of a study by the Idaho Bureau of Mines and Geology and the University of Idaho College of Mines, in cooperation with the U.S. Bureau of Mines, on the hydrogeologic factors that control the movement of groundwater through the abandoned Page tailings pile in the Coeur d'Alene Mining District in northern Idaho. A data collection network was installed to collect data on groundwater flow systems and groundwater quality in and surrounding the pile. Analysis of water level data showed the existence of a groundwater mound under the east portion of the tailings pile. The flow system in the pile is dynamic and responds both to precipitation events and to periods of no recharge. A finite element steady-state mathematical model was constructed to help interpret the groundwater flow system in the Page pile. A sampling and testing program of the pile provided information on values of hydraulic conductivity. These data were incorporated as input to the mathematical model. Operation of the model showed that the location and fluctuations of the regional groundwater table and the quantity of recharge to the tailings pile from precipitation were the primary controlling factors for the location and height of the groundwater mound under the east side of the pile. The rate of discharge of subsurface water from the pile was estimated from model operation to be about 2000 gallons per day per acre. This rate of discharge along with water quality data from the tailings pile showed that zinc reaches the immediate area outside the pile at a rate of about 17.8 pounds per day equal to about 0.1 percent of the total daily quantity of zinc carried by the South Fork of the Coeur d'Alene River at Smelterville during low flow.", "collection": "Coeur d'Alene Basin", "contributors": "Idaho Water Resources Research Institute; IWRRI", "publisher": "University of Idaho", "contributing-institution": "University of Idaho", "source": "University of Idaho", "language": "eng", "rights": "In copyright, educational use permitted.

Controlled greenhouse studies of garden vegetables and crops grown in trace metal contaminated soils from this locale suggest that most species suffer adverse growth effects and that all species accumulate the trace metals. A rapid decrease of trace metal concentrations in soils with increasing depth in the South Fork Coeur d'Alene River Valley indicates that these soils have become contaminated primarily as a result of atmospheric fallout/washout of smelter emissions. Under laboratory conditions the solubilization of these contaminants generally appears to have a linear relationship with time and rapidly reach equilibrium concentrations which are dependent on the pH of the soil solution and relative soil characteristics. Due to the high solubilities of the oxidation weathering products of the trace metal emissions and the river deposited mine wastes potentially high concentrations of trace metals can be rapidly leached from the contaminated soils by rainfall and high stage water tables.", "collection": "Coeur d'Alene Basin", "contributors": "Idaho Water Resources Research Institute; IWRRI", "publisher": "University of Idaho", "contributing-institution": "University of Idaho", "source": "University of Idaho", "language": "eng", "rights": "Copyright to this item is held by the author.

Without a clear understanding of contaminant redistribution, tailings transport, and metal cycling within this region, sound management decisions to protect environmental quality are difficult. Our objective was to better define the biogeochemical reactions controlling toxic metal cycling within sediments of Lake CDA and wetlands in the Basin. Sediment from contaminated sites in the Lake and Basin wetlands were collected as cores and interstitial water samples obtained using equilibrium dialyzers. Solid phase associations of Fe, S, and As were probed using x-ray absorption (XAS) spectroscopy. In Lake CDA sediments we identified a gradient from oxic conditions at the sediment-water interface to anoxic conditions below 10 cm, thus creating a dynamic redox environment that controls metal(loid) sorption and solubility. The oxic cap at the sediment-water interface traps many of the contaminant metal(loids) decreasing their flux into the overlying water column. However, flood events bury the oxic cap materials transitioning them to asuboxic zone in which reductive dissolution of the oxides releases metal(loid)s into the sediment interstitial water. High Fe:S ratios inhibit the formation of metal(loid)-containing sulfide precipitates in the anoxic zone, thus resulting in chronically and acutely toxic concentrations of soluble metals within the sediment interstitial water. In contrast, constantly saturated wetlands within the Basin do not maintain an oxic sediment cap and concentrations of metal(loid)s in sediment interstitial waters are consequently much lower than those in Lake CDA sediments. This series of reactions and processes presents a dilemma for lake management since promoting reduced conditions at the sediment-water interface in Lake CDA is an unacceptable method to decrease pore water metal(loid) concentrations. Decreased soluble metal(loid) concentrations in the sediments will only occur by minimizing the transport of contaminated materials to Lake CDA.", "collection": "Coeur d'Alene Basin", "contributors": "Idaho Water Resources Research Institute; IWRRI", "publisher": "University of Idaho", "contributing-institution": "University of Idaho", "source": "University of Idaho", "language": "eng", "rights": "In copyright, educational use permitted.

Data was secured for 8 farms by interviewing each farm operator and land owner. To make comparisons between farms and also between enterprises, the data was broken down into per acre variable costs, fixed costs, total returns, net income and the cost of producing a dollar's worth of output. The term 'cost per dollar of output' is the ratio of costs to returns. This ratio makes it possible to compare high-valued crops with low-valued crops on a per acre basis. This is a very sensitive measurement. For example, one cent change in the ratio for potato enterprise means a change in net income of $3.25 per acre. The budgeting method o f estimating water values in irrigation was used in this study. Long-run planning cost curves were estimated from the budgets by using (curvilinear) regression. From the regression equations for each of the four enterprises (grain, sugar beets, potatoes and alfalfa seed), 12 model farms were constructed. The long-run average total cost curve for the model farms, which incorporates a long-run rotation and long-run price and yield expectations, indicated economies of size up to a farm size o f 2,400 acres.

The laboratory study involved measuring the permeability of frozen soil columns at various initial moisture contents.

Two hundred, 400, and 600-acre farms were analyzed at irrigation efficiency levels of 50, 55, 60, and 65 percent. The farms were analyzed using differing numbers of wells. The 200-acre farm was the most restrictive because per acre returns were the lowest of the farms analyzed. Average conditions for a ZOO-acre farm showed water being delivered from one well at an irrigation efficiency of 55 percent. The economic maximum lift for this system was 389 feet. The economic maximum lift was 679 feet on a 400-acre farm with two wells and an irrigation efficiency of 55 percent. The economic maximum lift on a 600-acre farm with three wells and an irrigation efficiency of 55 percent was 767 feet.", "collection": "Boise Basin", "contributors": "Idaho Water Resources Research Institute; IWRRI", "publisher": "Idaho Water Resources Research Institute, University of Idaho", "contributing-institution": "University of Idaho", "source": "Idaho Water Resources Research Institute, University of Idaho", "identifier": "IWRRI Number 196908", "language": "eng", "rights": "In copyright, educational use permitted.

The discussion section concludes with possible restrictions on range use if the river was classified. Next, a test case is given in which the method presented is used. Alternative classifications are presented, an inventory made, resource maps considered, alternative classification evaluated and conclusions drawn. It was estimated that there were about 2.7 million acres of forest land and 2.4 million acres of range land grazed in the Basin. The AUM's on national forest land were approximately 129,000 and on BLM land, 239,000 respectively. The total number of permittees reported was 583.

There doesn't seem to be much conflict between grazing and river classification. Generally, there is little, if any, grazing in the areas which would be classified as scenic or wild and it is an established practice in the recreational portion. In the case of recreation, livestock grazing may present some problems in terms of river access. These primarily related to disturbing cattle on ranges and opening and closing of gates.

This project was designed to explore the role played by carbon and its subsequent use by bacteria on various chemical and biological parameters in Dworshak reservoir. Carbon contribution to the reservoir is primarily from the existing organic material present on the pre impoundment floor. This study defines methodology enabling prediction of the levels of carbon in a reservoir prior to impoundment and explores some of the effects of that carbon. In addition, these methods can be used to determine the amount of leached carbon, readily usable, by heterotrophic bacteria. The effect of carbon utilization by bacteria on algal growth is also explored. In the laboratory this symbiotic effect leads to significant increases in algal biomass even at carbon levels as low as 1. 3 ppm.

Middle Fork managers correctly predicted user reactions to more than three-fourths of the questionnaire statements presented in this study. Sampling included 253 of 367 floaters and all Forest Service personnel questionnaires were returned. Eighty percent of the statements were correctly perceived by managers. Forest Service personnel, however, did not accurately perceive many of the characteristics of users,. First, managers indicated that only 35% of the users would belong to conservation organizations while this study found that more than half (52%) of the users belonged to such organizations. Second, managers did not have a good indication of the educational level and income of floaters -- managers indicated that only 49% of the users would have a college education or higher and an average income of $15,000 while this study found that 69% of the users had a college degree or higher and an average in come of $26, 000. Finally, managers did not have a good indication of the types of user floating the Middle Fork managers indicated that 77% of the users fell into the commercial group while this study found that only 68% of the users fit into this category. Managers did not feel as strongly about environmental issues as did users. Fifty percent of the users showed a definite ''strong purist'' attitude about the environmental statements presented while managers indicated a less intense purist attitude. Users responded more intensely than managers to the importance of solitude in the wild river experience. Eighty percent of the users felt solitude was ''very important'' to the floating experience while only 58% of the managers indicated solitude was ''very important'' to the wild river experience. Managers appeared to be more development-oriented than did users. Ninety-two percent of the managers felt that users would be ''bothered'' at camping in places with no sanitary facilities or developed areas while 65% of the users indicated they would ''enjoy'' such areas. Forest Service personnel stressed stronger feeling toward the need for controls on the Middle Fork than did users. All managers favored controlling use of the river at the present time while only 64% of the users were in favor of such action. In addition, all Forest Service personnel indicated that limiting the size of parties floating the river is necessary while only 73% of the users favored party size limitations. The responses to management alternatives were not generally perceived by managers. Forest Service personnel indicated that users would oppose the restriction of limiting use to only those with prior river experience when in fact more than 20% of the users favored such action. In addition, approximately 80% of the Forest Service personnel responding felt users would favor the issuance of a limited number of permits on a first-come, first-served basis. A majority of the users (55%) indicated they were opposed to this alternative. Also, managers felt users would favor the assignment of campsites when in fact 59% of the users opposed this alternative.

An interview-type survey was obtained from the study area located in Ada and Canyon Counties, Idaho, for the purpose of completing partial farm budgets. Regression analysis applied to this data resulted in a unit cost curve showing slight economies of size for large farm acreages as opposed to smaller acreages. The unit cost curve was incorporated in the objective function of a linear programming model utilizing land, labor, and water as real restrictions. Artificial resources were Included in the activity analysis as restrictions to determine the optimum allocation of these resources for commodity production on 160, 320, 480, and 640 acre model farms. The outcome showed that the allocation of the resources for commodity production resulted in positive net returns for the three larger model farms. Also the activity analysis resulted in water being the most limiting resource. But the value of the irrigation water was shown to be comparable to water costs of other Southern Idaho irrigation areas. Projections of Income and population changes resulting from primary agricultural production on the project lands were also estimated. The data of the activity analysis were adapted to aparametric linear programming analysis to research the effect of varying potato and sugar beet commodity prices has on the resource allocation and production plans of the model feme. The conclusion of this analysis was that production of these two commodities is stable as large commodity price changes are necessary to alter the current resource allocation for changes in the production of either potatoes or sugar I beets.", "collection": "IWRRI", "contributors": "Idaho Water Resources Research Institute; IWRRI", "publisher": "Idaho Water Resources Research Institute, University of Idaho", "contributing-institution": "University of Idaho", "source": "Idaho Water Resources Research Institute, University of Idaho", "identifier": "IWRRI Number 197340", "language": "eng", "rights": "In copyright, educational use permitted.

Using Emerald Creek in northern Idaho as a study stream two types of in-stream modification structures, flow constrictors and drop structures, were designed, constructed and evaluated. Contour maps and thalweg profiles of the before and after modification conditions are presented for each of the five stream modification sites. Three drop structures were constructed at two sites on the upper reach of Emerald Creek. These structures concentrate the energy of the flow and scour a hole downstream of the structure. Considerations in the design of drop structures include forces on the structure, backwater caused by the structure, and depth of scour below the structure. In general the log drop structures per formed favorably. Scour holes formed downstream of two of the drop structures to a depth of 1.0 ft and 1.5 ft as compared to a predicted scour depth of 2.0 ft and 3.0 ft respectively. The scour holes were lined with rock from six to ten inches in diameter. The flow constricting structures were designed to reduce the width and increase the depth of flow during low flow periods to increase the sediment transport capacity of the stream thus flushing the silts and fine sands from the modified reach leaving cobble and small boulders. Gabion deflectors were used at two sites on the lower reach of Emerald Creek to constrict the flow. Log dikes were used at one site to constrict the flow and train the stream to follow a meandering flow path. Design considerations for flow constrictors include forces on the structure, location of structure, meander dimensions, and constriction dimensions. The performance of the gabion constrictors was acceptable at one site. Silts and sands were removed from the reach leaving cobble and boulders. Performance at the other gabion constrictor site was fair. Small amounts of silt and sand were removed from the reach. Cobble and small boulders moved into the constricted flow area from an upstream riffle. The log dikes used to form a meandering flow pattern during low flow appeared to be functioning as planned but were removed by high flows before analysis of the modification was completed. A method for measuring the streambed hydraulic conductivity using standpipes is suggested as a means for determining the change in bed characteristics resulting from deposition of silt. Calibration curves for the standpipes were developed in the laboratory for future testing in the field.", "collection": "IWRRI", "contributors": "Idaho Water Resources Research Institute; IWRRI", "publisher": "Idaho Water Resources Research Institute, University of Idaho", "contributing-institution": "University of Idaho", "source": "Idaho Water Resources Research Institute, University of Idaho", "identifier": "IWRRI Number 197416", "language": "eng", "rights": "In copyright, educational use permitted.

Where these barriers are transverse to the dip of the basalt layers, groundwater reservoirs are formed. Many such reservoirs are present in mountainous areas or on the flanks of mountain uplands, and their water has been little used to date.

Crumarine Creek watershed (1570 acres) is located approximately eight miles northeast of Moscow, Idaho. The watershed is mostly forested with a small amount of winter wheat grown near the outlet. The objectives of this thesis were to determine the amount and monthly pattern of deep percolation within the watershed by use of a monthly water balance equation and to analyze hydrologic responses of the watershed to rainfall and snowmelt. The hydrologic responses were analyzed by separating hydrographs into direct runoff and baseflow. HEC-1, the Army Corps of Engineers' (1981) flood hydrograph model, was also applied to the watershed to examine the disposition of excess precipitation. An annual deep percolation value of 7.5 inches was found to occur on Crumarine Creek watershed based on data from the 1969 to 1973 water years.

A three-dimensional numerical computer model of groundwater flow is constructed to guide this management. Basalt aquifer thicknesses of 0 to 3500 feet are determined by a magnetotelluric geophysical survey in support of the study. The model incorporates a Grande Ronde Basalt layer, a Wanapum Basalt layer, and an overlying surficial loess layer. A recharge rate of 139 cubic feet per second to the upper layer of the groundwater flow model is calculated using a recharge model developed by the U.S. Geological Survey. groundwater discharge is modeled as stream inflow and seepage where a layer is incised by a river. Cross-sectional models distributed across the domain of the three-dimensional model along flow lines provide an efficient means of obtaining hydraulic coefficient input for the three-dimensional model. The three-dimensional model is calibrated using the time-average method and evaluated through a history match procedure. The model incorporates numerous assumptions and simplifications; model predictions therefore are indicative only of general trends for the future. The model suggests that it is possible for groundwater levels to stabilize if groundwater pumpage stabilizes at a constant level. groundwater level declines will continue into the foreseeable future as long as groundwater pumpage continues to increase.", "collection": "Palouse Basin", "contributors": "Idaho Water Resources Research Institute; IWRRI", "publisher": "Idaho Water Resources Research Institute", "contributing-institution": "University of Idaho", "source": "Idaho Water Resources Research Institute", "language": "eng", "rights": "In copyright, educational use permitted.

An investigation of the groundwater resources in the Genesee area included well location, water level measurements, collection of pumpage records, and the compilation of geological and hydrological data for Moscow, Pullman, Lewiston, and Clarkston. A hydrogeological conceptual model was created for Genesee from comparisons of this data. The model indicates that several locations are not recommended for further development of the Wanapum aquifer because of contamination, elevation, low yield, and well interference. Based on the model, development of the upper aquifer may require the drilling of several test wells to obtain the desired yield. No conclusions can be made for the availability of water in the lower (Grande Ronde) aquifer. Careful collection of all geologic and hydrologic data is recommended during the construction of any new well. Water levels, water quality, and pumpage data should be collected on a regular basis.", "collection": "Palouse Basin", "contributors": "Idaho Water Resources Research Institute; IWRRI", "publisher": "University of Idaho", "contributing-institution": "University of Idaho", "source": "University of Idaho", "language": "eng", "rights": "In copyright, educational use permitted.

The purpose of this thesis is to characterize the surface-groundwater relation at the University of Idaho Groundwater Research Site (UIGRS), in the Pullman-Moscow basin, Washington and Idaho. Eighteen wells at the UIGRS; six wells are completed in alluvial sediments and broken basalts, and twelve at different depths and fracture zones in the Wanapum basalt. Two main fracture zones define two aquifers: theE-fractured and the W-fractured basalt aquifers. The surface-groundwater relation was defined by using qualitative analysis. The methodology used in this analysis was the interpretation of the water changes throughout a four-year period and on specific events using hydrographs of stream stage and groundwater levels, as well as precipitation. The water level of the creek and the shallow and E-fractured basalt aquifer wells followed the same fluctuation pattern, whereas the W-fractured aquifer wells behaved in a different manner. The difference may be related to the barometric effect' and/or to different sources of recharge. The character of the fluctuation for the shallow and Efractured aquifer was defined by the distance from the creek and by the intensity and distribution of precipitation. During the summer and early fall, as well as often during maximum streamflow events, Paradise Creek may recharge the shallow and E-fractured basalt aquifers. The main source of water may be direct precipitation throughout the rest of the year. It is suggested that continuous data recording and chemical data analyses would contribute valuable additional information about the recharge and discharge mechanisms of the Pullman-Moscow basin.", "collection": "Palouse Basin", "contributors": "Idaho Water Resources Research Institute; IWRRI", "publisher": "University of Idaho", "contributing-institution": "University of Idaho", "source": "University of Idaho", "language": "eng", "rights": "In copyright, educational use permitted.

The Palouse area relies almost entirely on groundwater for its supply of municipal, domestic and institutional water. The majority of the groundwater comes from two aquifers in the Miocene basalts of the Columbia River Basalt Group (CRBG) with associated interbedded gravel, sand, silt and clay. The upper aquifer is in the Priest Rapids Member of the Wanapum Formation and deeper aquifer is the Grande Ronde Formation. Decline in water levels in both aquifers has been the focus of considerable research into the hydrogeology of the system since the early 1970's. Groundwater research has added tot the general overall understanding of the region but no geologic or hydrogeologic model has adequately predicted or explained the system. Little geologic research has been conducted at scales less than 1:250,000. Previous investigations of rare outcrops along with sporadic detailed lithologic well data suggested that the basalt units are undeformed and nearly horizontal. Several isopach and structural contour maps were constructed for the basalt and sedimentary units. These maps indicate that the rock units are not horizontal and undeformed. A review of old and new geologic data supports the conclusion that the basalts are not horizontal, and that in places they are folded into narrow anticlinal ridges separated by wide sinclinal troughs. These structural features divide the Palouse area into at least two different sub-basins. Drainage pattern difference sin the Palouse area also suggest different sub-basins. In places, stream patterns can be related to structures identified on subsurface maps and/or existing geologic maps. Selective hydrogeological data were re-interpreted, and can be related to these sub-basins. These data consist of: groundwater pump tests, static groundwater levels and hydrographs. The combination of the structural contour and isopach maps, geological trends, drainage patterns, and re-interpreted hydrogeological data strongly indicate that the Palouse area is subdivided into at least two groundwater sub-basins with identifiable subsurface structural features.", "collection": "Palouse Basin", "contributors": "Idaho Water Resources Research Institute; IWRRI", "publisher": "University of Idaho", "contributing-institution": "University of Idaho", "source": "University of Idaho", "language": "eng", "rights": "In copyright, educational use permitted.

This thesis presents the results of a radiocarbon dating study completed in the Palouse Basin of eastern Washington and northern Idaho. The groundwater age or residence time, implies the amount of time elapsed between groundwater recharge and the time when the groundwater sample was collected. Estimates of groundwater age typically require extensive interpretations of physical, chemical and biological processes that act on 14C and should not be considered as a true age, but rather as a ''model age.'' Thirty-one samples were collected throughout the Palouse Basin between 2001 and 2003, in the loess, granite, Wanapum basalts, and primarily the Grande Ronde basalts. In the Palouse Basin, 14C concentrations indicate generally increasing age with increasing depth below the land surface. Relative ages of the groundwater in the four major pumping centers range from oldest in the Palouse and Moscow areas to youngest in the Pullman and Colfax areas. Historically, nonpumping water levels throughout the basin have shown relatively flat horizontal gradients compared to steep, vertical gradients, suggesting relatively high horizontal hydraulic conductivity in the basalt aquifers, and very low vertical hydraulic conductivity in the interiors of basalt flows. It is conceptualized that the Palouse Basin is characteristically shaped like a ''bathtub'' filled with basalt lava flows and interbedded sediments. Vertical groundwater recharge to the deep basalt aquifers is dominated by extremely slow vertical migration rates relative to current pumping withdrawals.", "collection": "Palouse Basin", "contributors": "Idaho Water Resources Research Institute; IWRRI", "publisher": "University of Idaho", "contributing-institution": "University of Idaho", "source": "University of Idaho", "language": "eng", "rights": "In copyright, educational use permitted.

Streamflow measurements from a 1984 USGS survey suggest that a significant amount of groundwater may be discharging from basalt aquifers and associated interbeds to streams within the area. Six Pullman-Moscow area streams which are incised into the basalt stratigraphy were investigated to locate zones where groundwater discharge/recharge is occurring. Stream temperature surveys and geologic cross sections were used to identify and describe possible groundwater discharge areas.

We measured bedload sediment transported in the streams during the spring snowmelt runoff and the summer lowflow periods for 2 years, to test the applicability of the Meyer-Peter, Muller equation for estimating such transport. In both years the streams transported all the sediment available, including that under the armor layer of the stream bottom in the first year. The modified MeyerPeter, Muller equation proved accurate in estimating the transport capacity of such streams using measurements of slope, hydraulic radius and mean diameter of streambed material. In artificial stream channels, benthic insect density in fully sedimented riffles(> 2/3 cobble imbeddedness) was one-half that in unsedimented riffles, but the abundance of drifting insects in the sedimented channels was not significantly smaller. In a natural stream riffle, benthic insects were 1.5 times more abundant in a plot cleaned of sediment, with mayflies and stoneflies 4 and 8 times more abundant, respectively. Riffle beetles (Elmidae) were more abundant in the uncleaned plot. During both summer and winter, fewer fish remained in the artificial stream channels where sediment was added to the pools. The interstices between the large rocks in the pools provided essential cover necessary to maintain large densities of fish. Fish in sedimented channels exhibited hierarchical behavior, while those in unsedimented channels were territorial in behavior. In small natural pools ( 100 to 200 m^2 ), a loss in pool volume or in area deeper than 0.3 m from additions of sediment resulted in a proportional decrease in fish numbers. We did not, however, find significant correlations between riffle sedimentation and fish density in the two natural streams we studied. Fish abundance was significantly correlated with insect drift abundance in one stream, but not in the other. The amounts of sediment in the two streams studied did not have an obvious adverse effect on the abundance of fish or the insect drift on which they feed.", "collection": "IWRRI", "contributors": "Idaho Water Resources Research Institute; IWRRI", "publisher": "Idaho Water Resources Research Institute, University of Idaho", "contributing-institution": "University of Idaho", "source": "Idaho Water Resources Research Institute, University of Idaho", "identifier": "IWRRI Number 197701", "language": "eng", "rights": "In copyright, educational use permitted.

This three-dimensional model was transferred from the University of Idaho mainframe computer to personal computer compatible files. These original file are retained for time-averaged, history-match and predictive simulations. The Pullman-Moscow groundwater flow model includes several assumptions which are difficult to support with the current level of information. Probably the greatest concern is the uncertainty of recharge and discharge to the deepest model layer in the Grand Ronde basalt. Most recharge to and discharge from this layer can not be directly measured. Evidence suggests, however, that discharge along the Snake River canyon has been overestimated. Over-estimation of this discharge would have adversely affected model calibration.

The specific conductance of groundwater in well USGS-59, as measured in the borehole, ranged from about 450 to 900 flS/cm at standard temperature (25 C). The pumping cycle of the production wells at the Idaho Chemical Processing Plant causes changes in borehole circulation patterns, and as a result the specific conductance of groundwater at some depths in the well varies by up to 50% over a period of about 14 hours. However, these variations were not observed at all depths, or during each pumping cycle. The temperature of groundwater in the well was typically between 12.8 and 13.8 C The results of this study indicate that temporal variations in specific conductance of the groundwater at this location are caused by an external stress on the aquifer - pumping of a production well approximately 4000 feet away These variations are believed to result from vertical stratification of water quality in the aquifer and a subsequent change in intra well flow related to pumping.

Removal of barometric effects on well-water elevations allows measurement of external stresses [such as changes in drawdown during aquifer tests] that could be obscured by well-water fluctuations caused by barometric pressure changes. Multiple-regression deconvolution reveals that the wells penetrate confined aquifers and that well-water levels in one well are affected by wellbore storage or skin effects. Application of a simple linear regression model between barometric pressure and spring discharge at National Fish Hatchery #15, Blind Canyon Springs, and Sand Springs suggests that changes in spring discharge may be independent of barometric pressure. Alternatively, changes in spring discharge are less than the precision of the instruments measuring discharge. Because the hydraulic gradient in parts of the ESRP aquifer is as low as 1 ft per mile [0.0002 ft/ft], the addition of atmospheric head to elevation head should be further evaluated.

During the period from 1995 through 1998, the National Marine Fisheries Service (NMFS), the U.S. Fish and Wildlife Service, and the Nez Perce Tribe investigated migration characteristics of hatchery-raised, subyearling fall chinook salmon (Oncorhynchus tshawytscha) in the Snake River Basin (Muir et al., 1999). Hatchery raised subyearlings were used as surrogates for wild subyearlings in the survival research. The studies showed that estimated survival from points of release to the tailrace of Lower Granite Dam could be correlated with all three environmental variables examined (flow rate, water temperature, and turbidity). Estimated survival decreased throughout the season, as flow volume and turbidity decreased and water temperature increased (Muir et al., 1999). These correlations have provided the primary basis for the continuation of flow augmentation from reservoirs in the Snake River and Clearwater River Basins (NMFS, 1999). The purpose of this report is to provide a review of the data considered in the Muir et al. (1999) study within the context of determining the efficacy of flow augmentation for enhancing the survival of subyearling fall chinook. In particular, relationships between flow rates, water temperatures, travel times, and estimated survival of hatchery-raised, subyearling fall chinook salmon between points of release and detections at Lower Granite Dam are examined. This report includes analyses of: (1) flow rates and water temperatures at Lower Granite Dam; (2) estimated survival with 5th percentile flow indices; (3) estimated survival and 5th percentile water temperature indices; (4) estimated survival versus release dates; (5) estimated survival versus release groups; and (6) fall chinook travel times and numbers of detections. Finally, these comparisons are used to draw conclusions about flow rates, travel times, subyearling survival, and effectiveness of flow augmentation.", "collection": "IWRRI", "contributors": "Idaho Water Resources Research Institute; IWRRI", "publisher": "Idaho Water Resources Research Institute, University of Idaho", "contributing-institution": "University of Idaho", "source": "Idaho Water Resources Research Institute, University of Idaho", "identifier": "IWRRI Number 200003", "language": "eng", "rights": "In copyright, educational use permitted.

Nitrate-n concentrations ranged from 0.1 to 2.2 mg/L, well below the USEPA recommended limit of 10 mg/L. The mean specific conductance was 371 micromhos/cm at 25 C. Mean concentrations of nitrate-n, chloride, and orthophosphate from surface-water samples were 0.44, 1.8, and .015 mg/L, respectively. groundwater levels were measured in approximately 60 wells from which a water-table contour map and a groundwater/surface-water profile were constructed for July-August, 1983. The profile indicates hydraulic connection between groundwater and surface water in much of the study area.

One of the anticipated drivers of future needs and supply constraints is climate change, and one anticipated response is to provide additional storage capacity to mitigate the effects of altered patterns of runoff from mountain snowpack. Local aquifers can potentially provide additional storage. Managed aquifer recharge means to intentionally place water in the aquifer at times when supplies exceed current needs, for later withdrawal when supplies are short. It may provide storage at lower cost than building new surface-water structures, protects water from evaporation, and does not carry the threat of catastrophic flood from infrastructure failure. Aquifer recharge can also mitigate the potential loss of surface storage capacity due to increased flooding risks posed by climate change. With a robust and active aquifer recharge program, carryover water that is at high risk of being spilled for flood-control purposes can be moved to storage in the aquifer and thereby retained in the basin for future use. This paper provides an initial look at managed recharge, to set the stage and provide context for consideration by participants in the CAMP process. It addresses: (1) Hydrogeology and current aquifer conditions. (2) Potential storage capacity of the Treasure Valley Aquifers available for managed recharge. (3) Location of potential recharge sites. (4) Capacity to deliver water to the recharge sites. (5) Approximate residence time of water stored in the aquifer, before it is depleted by migration to hydraulically-connected surface-water bodies.", "collection": "IWRRI", "contributors": "Idaho Water Resources Research Institute; IWRRI", "publisher": "Idaho Water Resources Research Institute, University of Idaho", "contributing-institution": "University of Idaho", "source": "Idaho Water Resources Research Institute, University of Idaho", "identifier": "IWRRI Number 201102", "language": "eng", "rights": "In copyright, educational use permitted.

The investigations showed that the present systems are quite inefficient due to soils with high water intake rates, long irrigation runs and duplication of many irrigation canals. Engineering and economic analyses were made to determine the least cost method of rehabilitating the present system and to determine the capability of the area to support various rehabilitation schemes. Both analyses utilized linear programming models to determine optimum solutions subject to various social and legal constraints. The results obtained indicate that present practices are the most economical for the present cost and availability of water. Wells equipped with high head pumps supplying sprinkler systems appear to be the best alternative if a marked increase in overall irrigation efficiency is to be achieved.

The effect of discharge on aquatic insect population below Dworshak Dam on the Clearwater River, Idaho was measured during different peaking regimes. Insects were sampled using a cylindrical bottom sampler, drift nets, basket samplers and embedded canisters. The benthic insect community below Dworshak Dam has remained relatively stable during and after the filling of Dworshak Dam but shorelines experiencing daily fluctuations are not readily colonized by stoneflies, mayflies and caddisflies; chironomid midges are the most resilient stranded insects in these unstable areas and the first ones to recolonize the flooded areas. The insects collectively reflected an obvious diel drift pattern with largest numbers drifting at night. Samples selected from three depths (15, 30 and 45 em) yielded the largest numbers of insects at the 45 em depth. When converting numbers of drifting insects to a volume-flow relationship, largest numbers of insects were captured at the 15 em depth. Basket sampling at depths of 1 and 2 m revealed no major differences in the insect community at these depths. A total of 98 species from eight orders of insects were recorded from the Clearwater River. Flows in a diversion channel (3.5 m in width) on the South Fork of the Salmon River were manipulated to experimentally simulate flow fluctuations below a power dam. An upstream section (20m in length) tested insects; a downstream section (60 min length) tested fish at 24-hour sequences of 57, 17, 3 and 51 1/sec. Analysis of vertical distribution of insects in the controlled flow channel indicated that the insects did not generally seek greater interstitial depths during dewatering and that many of the insects had become displaced via drift during the dewatering cycle. Stepwise reduction of discharge caused corresponding reductions in the number of chinook salmon (Oncorhynchus tshawytscha). The carrying capacity of the channel was 250% greater in the summer when salmon were smaller (<59 mm) and stream temperatures were higher (8-17 C) than in the fall when fish were larger (95-102 mm) and temperatures lower (4-15 C). Although the summer and fall carrying capacities differed, the proportion of fish remaining in the channel after each reduction in flow was about the same. The number of chinook in an experimental laboratory flume also changed directly with variation in the rate of flow. These findings corroborated with those for the diversion channel. Extreme reductions in flow significantly increased the amount of insect drift and the rate of ingestion by salmon in the diversion channel.", "collection": "IWRRI", "contributors": "Idaho Water Resources Research Institute; IWRRI", "publisher": "Idaho Water Resources Research Institute, University of Idaho", "contributing-institution": "University of Idaho", "source": "Idaho Water Resources Research Institute, University of Idaho", "identifier": "IWRRI Number 197610", "language": "eng", "rights": "In copyright, educational use permitted.

However, they are more likely to use those practices that are least costly and troublesome to adopt rather than those known to be most effective. Farmers believe they are doing more to control erosion than self-reported behavior indicates. Greater use of erosion control measures tends to be positively associated with larger farm sizes, higher gross incomes, and higher educational levels. Absentee land ownership is an important part of Palouse farming; the average farmer leases 55 percent of the land he farms.

Some of the large pools in the Snake River contained more than 200 sturgeon, according to our estimates. By expanding the population estimates we made for several pools in the river, we believe 8,000-12,000 sturgeon resided in the study area during the period 1973-1975. Small sturgeon (less than 3 feet) were the most abundant (86%) of the fish caught. Sturgeon 3-6 feet in length were least abundant (4%) and large fish (over 6 feet in length) comprised 10% of the fish we caught. There was some tendency for the small 2 to 3 foot sturgeon to move downstream, whereas the larger sturgeon did not move far from the original site of capture. Growth of sturgeon produced since dams were constructed in Hells Canyon was less than for sturgeon produced prior to damming of the river. Sturgeon are reproducing successfully in the middle section of the Snake River but the population may not thrive as in past years if the growth rate has indeed slowed and if critical habitat for the rearing of 3-6 foot sturgeon has been eliminated by dams in the lower Snake River", "collection": "IWRRI", "contributors": "Idaho Water Resources Research Institute; IWRRI", "publisher": "Idaho Water Resources Research Institute, University of Idaho", "contributing-institution": "University of Idaho", "source": "Idaho Water Resources Research Institute, University of Idaho", "identifier": "IWRRI Number 197708", "language": "eng", "rights": "In copyright, educational use permitted.

The concept and application of pumped storage are discussed, particularly as they relate to the Pacific Northwest. An overview of the Hell's Canyon area is presented, focusing on its physical characteristics, history, and current National Recreation Area status. Eighteen potential pumped storage sites are noted, and three of the most promising are selected for more detailed analysis. For the three selected sites, preliminary designs are developed based on characteristics of actual pumped storage projects. Also presented are the results of a computer study of the reservoir water level fluctuations which would be induced by pumped storage operation. The computer program developed for the study is documented in the Appendix. The three sites are analyzed for economic feasibility, based on a procedure developed by the U. S. Army Corps of Engineers. It is concluded that pumped storage in the area is too expensive to be competitive at the present time, but may be feasible in the future. Possible major social and environmental effects are noted, although no actual analysis was performed. The three selected sites are compared, and one (Barber Flat in Idaho) is recommended for further consideration. Two possible alternative uses of pumped storage in the Hell's Canyon area are briefly discussed: (1) the use of pumped storage to relieve Hell's Canyon Dam of objectionable peaking duties; and (2) the use of a pumped storage reservoir to cool a nuclear power plant.

Macroinvertebrate biomass and diversity values varied significantly (P<.05) both between different stream orders, and between streams of the same order. Biomass and diversity variability was correlated with physical and chemical factors by stepwise regression analysis. A large percentage (>85%) of the variance in both biomass and diversity was accounted for by changes in four to five physical and chemical factors, which included substrate size, gradient, suspended sediment water temperature, alkalinity, stream order and width. This indicates that predictive modeling of macroinvertebrate community structure is possible in a small, relatively undisturbed watershed. Basket, multiple-plate and Surber macroinvertebrate samplers were used to determine which sampler is most applicable for use in small relatively undisturbed streams. Comparisons were made on the basis of sample biomass) diversity and taxonomic composition. Basket samples had more biomass and higher diversity than multiple-plate samples throughout the watershed, probably because they provided a better imitation of the natural substrate. Basket sample diversities were similar to Surber sample diversities in first and second order streams, but were much lower in third and fourth order streams. Both basket and multiple-plate samplers were found to be adequate for stream survey work.

The study examined two important changes in the River: 1) effects of hydropower releases from Dworshak Dam on the aquatic insect community in the free flowing reach of the Clearwater River, and 2) backwater effects of Lower Granite Dam on benthos in the lower five miles (8 km) of the Clearwater River. As result of the operational mode of Dworshak Dam, late summer and fall flows are greater than during the pre-project era. Although hydropower releases cause frequent and marked fluctuations in discharge, there is a stable post project low flow. This higher late summer flow guarantees the submergence of additional substrate, thereby increasing macrobenthic habitat. Over 120 species of aquatic insects exclusive of Chironomidae have been collected from the Clearwater River. While small to moderate shifts in seasonal densities of principal species have occurred between intensive study sites above and below the influence of Dworshak Dam, present evidence does not indicate these shifts are attributable to hydropower releases. Approximately one month was required for sterile rocks to support a standing crop similar to that of continually watered rocks. In most instances, numbers of species and densities increased with increasing depth of 15, 30 and 45 cm. Numbers of drifting insects were greatest during the nights. Drift rates and standing crop relationships above and below the influence of Dworshak Dam suggest insects drifted more in response to daily fluctuations than to the factor of bottom density. Within the lower five miles of the Clearwater, variable backwater effects of Lower Granite Reservoir have a far more pronounced effect on the amount of potential benthic habitat available than do releases from Dworshak Dam.

It is used in determining total irrigation water requirements and in sizing the irrigation system components. Irrigation efficiency is not a deterministic parameter; the occurrence and sequencing cannot be predicted with complete reliability.

A Bayesian decision theory optimization model was developed that explicitly incorporated the uncertainties inherently associated with the probabilistic hydrologic and irrigation efficiency phenomena.

A soil erosion model was coupled with the Idaho version of the USDAHL watershed model which supplied primary information such as rainfall, snowfall, snowmelt, overland flow, stream flow, soil moisture and crop growth index to the erosion model. The main factors used by the erosion model are: overland flow, rainfall, snowmelt, snow covered area, organic material covered area, soil moisture, rill development on upland areas and stream flow for channel scouring. These are used to calculate soil particle detachment and transport capacity of raindrop and overland flow. There are several coefficients which are used to estimate the conditions for or against soil erosion. This first generation Palouse erosion model was fitted to measured sediment discharge by using trial-and-error techniques. The model was tested on two different size watersheds (3.3 hectare and 59.4 hectare) near Moscow, Idaho. The results showed poor simulation on a daily basis. The monthly and yearly simulations were good compared with the observed except for the period of high stream flow simulated at the start of the water year. The eroded particles from each hydrologic zone cascades to a lower zone and finally to the channel. This cascading system shows the amount and location in terms of zones, where the erosion and deposition occur. Rill depth and distribution for any erosion period are the most important part of the model since rill erosion is calculated as a function of them. From field measurements rill erosion has proven to be one of the most serious erosion sources in the Palouse. Channel scouring erosion is not as significant as upland erosion. High stream flow does not necessarily cause high soil loss and vice versa. Many of the problems, particularly with upland erosion, can be traced to inadequacies in the hydrologic model. This is the first study of its type in the Palouse area. There must be further calibration and modification of both the hydrologic and erosion model in order to improve the simulation of erosion in this area.", "collection": "IWRRI", "series": "Water for Idaho", "contributors": "Idaho Water Resources Research Institute; IWRRI", "publisher": "Idaho Water Resources Research Institute, University of Idaho", "contributing-institution": "University of Idaho", "source": "Idaho Water Resources Research Institute, University of Idaho", "identifier": "IWRRI Number 197815", "language": "eng", "rights": "In copyright, educational use permitted.

Mud Lake has been modified by the construction of dikes and levies to provide storage of approximately 64,200 acre feet. The water supply is furnished by surface runoff from Beaver Creek and Camas Creek and by artesian and pumped wells from the Snake Plain Aquifer. Beaver Creek, with a drainage area of approximately 510 square miles is tributary to Camas Creek at a point near Camas, Idaho, and normally dries up in late spring. There are irrigation diversions on Beaver Creek above Camas Creek serving approximately 5,800 acres. The topography of the Beaver Creek drainage confines the stream except for the lower reach just above Camas. Camas Creek originates in the Beaverhead mountains and irrigates approximately 8,100 acres above Camas. Major tributaries are West Camas, East Camas, and Beaver Creeks. A dam was constructed on Camas Creek near Lone Tree but is not currently functioning. The diversion structure at Lone Tree is capable of diverting approximately 1000 cfs into the basalt and lava flows east of Camas Creek. This diversion has been used in the past to divert flood flows from Camas Creek which then sink into the fractured basalt. Another main diversion from Camas Creek is the Warm Creek channel through which up to 200 cfs can be diverted in the NE 1/4 SW 1/4 Sec 28 T 8N R 36E. Flows in Warm Creek fill depressions and ponds in the upper areas of the wildlife refuge, with the remainder returning to the Camas Creek channel. Camas Creek drains an area of approximately 1130 square miles above Mud Lake and flows through the Camas Wildlife Refuge into Mud Lake through a regulating structure called the Bybee gates or Bybee structure. The gates at the Bybee structure can be closed to retain Camas Creek discharge in the refuge area or opened to fill Mud Lake. Rays Lake, within the Camas Wildlife Refuge, is served by Camas Creek and also serves as a reservoir for irrigation pumping for lands to the south of Camas Creek. Also within the Camas Wildlife Refuge are numerous artesian and pumped wells which are used by the Federal Fish and Wildlife Service to maintain water levels in the surface ponds. Artesian flow from wells is collected in ditches and transported to Mud Lake during both the winter and irrigation periods. These wells are generally shallow wells penetrating the basalts of the Snake Plain Aquifer which is partially confined in the area just north and east of Mud Lake. The primary groups of users which utilize well water are the Independent Water Users, the Owsley Canal, and the Holly Water Users. Normally, these wells flow under artesian conditions in the winter and spring and are pumped after the irrigation season begins; however, the wells are pumped during late winter and spring during low water years. During years when flood conditions are imminent, these wells can be, and have been, capped to reduce inflow into Mud Lake. Mud Lake and the watersheds of Beaver Creek and Camas Creek are administered by Water District 66. The watermaster for this district is Mr. Don Shenton, who has held that position since 1960. During the irrigation season, the watermaster allocates water according to a federal decree which includes all water users. Because of the relationships between surface water and groundwater systems and the complicated operation of artesian well systems, evaluation of the effects of changes in surface flows or utilization of wells on Mud Lake is not possible without a computer based water balance model. In order to evaluate the efficiency and/or impacts of possible flood control measures on Mud Lake, a simplified water balance model of the system was developed.", "collection": "IWRRI", "series": "Water for Idaho", "contributors": "Idaho Water Resources Research Institute; IWRRI", "publisher": "Idaho Water Resources Research Institute, University of Idaho", "contributing-institution": "University of Idaho", "source": "Idaho Water Resources Research Institute, University of Idaho", "identifier": "IWRRI Number 198802", "language": "eng", "rights": "In copyright, educational use permitted.

In addition, variables related to predicting diversions were presented and their relationships described. The physical model developed was designed to accurately represent the physical processes of water conveyance and use in an irrigation system. Required inputs included crop consumptive use and irrigation efficiencies in conjunction with time variables such as irrigation interval, irrigation application time and traveling time in the system. Results from the physical model indicated that more data would be necessary for accurate predictions in addition to updating procedures to account for seasonal variations within the system and management. Statistical models were developed using multiple regression techniques. Required inputs included evapotranspiration, precipitation, weekly variation of water use, previous diversions and dummy variables used to account for monthly and seasonal variations of soil moisture management.

The results obtained from the simulation and field studies clearly indicate catastrophic influences of volcanic ash deposition and transport on attached benthic algae biomass and on the dislocation of invertebrates and interruption of food-chain relationships.

Increases in groundwater pumping rates, primarily for irrigation, have led to changes in surface streamflow, affecting previously allocated surface water rights. However, the magnitude of this effect and its variability over time remain difficult to estimate. The primary objective of this study was to develop a multivariate monthly flow model for Camas Creek, based on stream flows in neighboring basins, and to test whether such a model is sensitive enough to detect, at some statistical level of significance, any streamflow changes that may have resulted from groundwater withdrawals. Monthly streamflow records from Camas Creek and three similar neighboring basins were used to develop a multivariate monthly streamflow model of Camas Creek. Model parameters were based on the recorded statistics for the record period common to groundwater development within the Camas Creek basin. The model was developed and tested for its ability to adequately reproduce the historic pre-irrigation time series for Camas Creek. Then the model was applied to the time period in which significant groundwater withdrawals occurred. A comparison of the modeled streamflow with the actual flows for this period was used to estimate the impacts of groundwater pumping on monthly, seasonal, and annual streamflows. The differences between the two time series were related to the history of groundwater development within the basin. Although the model appeared to simulate the overall historic time series reasonably well, its performance varied by month and season. The application of the model to the time period in which the Camas Creek basin groundwater withdrawals were significant produced a simulated record with lower streamflows than those observed. This may be attributed to the fact that most of the large wells have pumped from deep aquifers, with no connection to the surface stream aquifers.", "collection": "Boise Basin", "series": "Water for Idaho", "publisher": "Idaho Water Resources Research Institute, University of Idaho", "contributing-institution": "University of Idaho", "source": "Idaho Water Resources Research Institute, University of Idaho", "identifier": "IWRRI Number 198902", "language": "eng", "rights": "In copyright, educational use permitted.

Using data from a study done by the U.S. Geological Survey in the 1970's and up-to-date data collected for this study, a three-dimensional numerical computer model of the groundwater-flow system was constructed to provide an understanding of the geohydrology of the study area. The groundwater-flow model incorporates three layers -- an overlying surficial loess layer, a Wanapum Basalt layer, and a Grande Ronde Basalt layer. A groundwater-system recharge rate was estimated using a methodology developed by the U.S. Geological Survey. groundwater discharge was modeled as groundwater pumping, flow to rivers and streams, and flow out of seepage faces, where a layer is incised by a river valley. Three cross-sectional flow models, distributed across the domain of the three-dimensional model along estimated flow lines in the Grande Ronde Basalt, were used to obtain hydraulic coefficient input for the three-dimensional model. The three-dimensional model was calibrated using the time-averaged method for the period 1974-85, and was evaluated by simulating historical pumpage rate changes (1890-1985) and comparing simulated with observed water-level changes. Model results suggest that groundwater levels would stop declining if groundwater pumpage were to stabilize at a constant level. However, groundwater levels will continue to decline in the foreseeable future as long as groundwater pumpage continues to increase. Further study of the recharge, movement, and discharge of groundwater in the area is needed to increase the accuracy of any groundwater-flow model to predict the response of the flow system to future pumping stresses.", "collection": "Palouse Basin", "publisher": "Idaho Water Resources Research Institute, University of Idaho", "contributing-institution": "University of Idaho", "source": "Idaho Water Resources Research Institute, University of Idaho", "identifier": "IWRRI Number 199004", "language": "eng", "rights": "In copyright, educational use permitted.

The overall thickness of the soil cover was measured with a hand auger at 60 locations across the landfill. A field procedure using cheese-cloth and resin was successfully used to collect large, undisturbed specimens of coarse-grained soils. Water retention tests of the large cores and smaller specimens comprised of the fine fraction (particles smaller than 2.0 mm) provided relationships of capillary pressures vs. water content. Historical meteorological data from a 31-year record was used to estimate the amount of water available for annual infiltration through the soil cover (i.e., recharge). The median value of annual (PPT-ETA) was combined with block-kriged maps of cover thickness, percent-fines in Layer 1, and percent-fines in Layer 2 to generate maps depicting the estimated annual infiltration through the cover (in 50 x 50 ft. cells) for a \"median year. Based on results, regulatory closure f CFA Landfill II will require the design and construction of a soil cap.

The canal system was simulated using the hydraulic simulation model CANAL, developed at Utah State University. The objectives were to determine the effects of the non-continuous turnout operation and to evaluate the effects of alterations to the canal system upon fluctuating flow rates and water levels. Simulations evaluated increasing the number and size of spillways, modifications to channel cross sections, modification and addition of check structures, and restricting the timing and number of turnouts with non-continuous flow. Non continuous turnout operation was found to cause little variation in water level in some areas of the canal system, and large variation in others.

Feasible alterations to the canal system had limited effects upon the fluctuations in flow rate and water levels caused by the non-continuous turnout operation.

The approximation of a groundwater flow system with a numerical model incorporates many simplifications. Accuracy of the model results is dependent on model construction and the validity of the input values that characterize the system. A sensitivity analysis is conducted on model responses to variations in: a) areal recharge to the groundwater basin, b) seepage discharge from the face of the Snake River Canyon, and c) constant head versus constant flux boundary conditions. Sensitivity studies demonstrate that simulated water levels in the Grande Ronde Basalt near Pullman and Moscow are relatively insensitive to changes in areal recharge, Snake River Canyon seepage, and model boundary conditions. This is believed to result from model construction and may not be conceptually correct.

Structures were built in six canals in southeastern Idaho. Design discharges ranged from 100 to 600 cubic feet per second, while tailwater depths range from 2.75 to 5.45 feet.

Demonstrated fatal toxicity to cattle and small mammals occurred in 1981, 1982, 1983, and 1985. The eutrophication and subsequent toxic blooms in Black Lake can be related to its large nonpoint nutrient input from the surrounding watershed. The presence or absence of cattle on adjacent meadows may be a major determining factor in bloom formation. Despite a high proportion of sediments (55 percent) exposed to anaerobic conditions during summer stratification, it appears that internal loading alone does not play a significant role in the triggering of a toxic bloom in Black Lake. Development of A. flos-aquae bloom in Black Lake is dependent on a series of interdependent environmental controls. The most important conditions in Black Lake appear to be high spring nutrient load (compounded by the presence of cattle), high fall water temperature, and stable water column conditions in the fall. The A. flos-aquae strain present in Black Lake formed surface concentrations and produced anatoxin-a, despite comprising only 1 to 2 percent of the total algal biovolume in the water column.

The model incorporates a Grande Ronde Basalt layer, a Wanapum Basalt layer, and an overlying surficial loess layer. A recharge rate of 139 cubic feet per second to the upper layer of the groundwater flow model is calculated using a recharge model developed by the U.S. Geological Survey. groundwater discharge is modeled as stream inflow and seepage where a layer is incised by a river. Cross-sectional models distributed across the domain of the three-dimensional model along flow lines provide an efficient means of obtaining hydraulic coefficient input for the three-dimensional model. The three-dimensional model is calibrated using the time-average method and evaluated through a history match procedure. The model incorporates numerous assumptions and simplifications; model predictions therefore are indicative only of general trends for the future. The model suggests that it is possible for groundwater levels to stabilize if groundwater pumpage stabilizes at a constant level. groundwater level declines will continue into the foreseeable future as long as groundwater pumpage continues to increase.", "collection": "Palouse Basin", "series": "Water for Idaho", "publisher": "Idaho Water Resources Research Institute, University of Idaho", "contributing-institution": "University of Idaho", "source": "Idaho Water Resources Research Institute, University of Idaho", "identifier": "IWRRI Number 198713", "language": "eng", "rights": "In copyright, educational use permitted.

(2) Irrigation disposal of effluent will cause little if any fluoride contamination of the shallow aquifer. (3) The irrigation method best suited for disposal is surface irrigation with borders. The irrigation system will experience problems with cold weather operation. Crop emergence will be hindered by border irrigation.

(4) Investigation of the relationship between heat input, snow covered area, and runoff. The development and comparison of the simplistic and typical snow covered area maps revealed that there were differences between the two representations. Since the SSARR model, which is presently used for runoff forecasting by the Corps of Engineers uses the simplistic representation of snow depletion, these differences could lead to some possible problems in the model's snowmelt prediction routines. The slope aspect studies revealed that the distribution of slope aspects within and between subbasins was not equal. Since slope aspect can affect snowmelt patterns, this unequal distribution could present problems to the runoff modeling process if these distributions are not accounted for in the model. The average snow line studies revealed that snow lines were not at constant elevations for given snow covered areas as is assumed in the present modeling scheme. Graphs are provided to help determine a realistic snow covered area after estimates of snow line are determined from snow flight data.

It continued work begun in the late 1980s to assess the vulnerability of groundwater of the Snake River Plain aquifer in southern Idaho (Rupert et al. 1991). There were three main tasks in this study. The first task was to apply the rating system developed by Rupert et al. (1991) to other types of aquifers in Idaho. The second task was to perform a verification of the rating system for its validity and reliability. The third task was to map the components of groundwater vulnerability at a scale of 1:24,000, modifying the vulnerability assessment method as necessary. An area in western Jerome County was chosen for examination and mapping at that scale. In task one, the Rupert rating system was applied to the Rathdrum Prairie aquifer in northern Idaho, to the Big Wood River-Silver Creek aquifer in south central Idaho, to a portion of the Snake River Plain aquifer near Burley, and to the Jerome County study area. In task two, a statistical analysis was performed on the application of the rating system to each of the aquifers as well. The results of tasks one and two are reported in the section, \"Application and Analysis of Rupert et al. Rating System.\" The results of task three, mapping at a scale of 1:24,000, are presented in the \"Jerome Pilot Project\" section. The last section of the report, \"Conclusions and Recommendations\" summarizes what has been learned in the two studies and makes recommendations for future approaches to groundwater vulnerability mapping.

In an effort to gain an understanding of the area geohydrology, the city contracted with the University of Idaho Water Resources Research Institute to develop a numerical groundwater flow model for the aquifer underlying the city of Twin Falls. The steady state groundwater flow model was developed based on recharge and discharge data from the last twenty years. The primary source of recharge to the area is irrigation by the Twin falls Canal Company. Evapotranspiration and unmeasured springs to the Snake River and other surface streams are important sources of discharge from the aquifer. A water budget for the basin was developed using precipitation, surface flow and crop distribution data. Evapotranspiration was calculated using average crop distributions and reference evapotranspiration values. Applied irrigation water was calculated from diversions, measured irrigation returns and land use data. Underflow from tributary basins was estimated or obtained from the literature. The steady state numerical groundwater flow model was calibrated to water level measurements taken from December 1995 to December 1996. The network of 113 wells was measured five times in that thirteen month period. The model parameters which were calibrated were model hydraulic conductivity and spring conductance. Comparison of simulated water levels with measured water levels resulted in a mean absolute error of 17.5 ft. and a root mean square of 24.4 ft., with eighty-one percent of simulated water levels being within 30 feet of measured water levels. As stresses on the aquifer grow, water levels are dropping, causing concern over increased pump lifts and reduced spring flows.

A demonstration field was selected at each of two farms for a pilot groundwater project primarily to monitor potential nonpoint source groundwater nitrate contamination and to evaluate the effectiveness of two United States Department of Agriculture (USDA) recommended Best Management Practices (BMPs): (1) a nutrient management BMP through crop rotation and (2) a nutrient management BMP through reduced irrigation water application. An EPA suggested paired watershed approach was used to evaluate independently a different BMP at each demonstration field. For the paired watershed approach, each field was split into a control half and treatment half, and two periods of study were evaluated, a calibration period and a treatment period. The focus of this investigation was to evaluate MBP treatment period effects on groundwater nitrated concentrations in shallow, perched aquifers underlying both demonstration fields, that are highly susceptible to agricultural nitrate contamination. A geostatistical approach was developed to evaluate nitrate concentration distributions and BMP effectiveness. A monitoring network of lysimeters, groundwater point samplers, and/or shallow wells based, in part, on a geostatistical-oriented design was installed at each demonstration field. Monthly nitrate data collected for these monitoring networks were evaluated using two different types of geostatistical approaches. A sequential Gaussian (SGS) simulation approach was used to evaluate groundwater and soil water nitrate concentration distributions at the crop rotation BMP demonstration field (i.e., Forgeon Field). A trend surface analysis (TSA) approach was used to evaluate groundwater and soil water nitrate concentration distributions at the irrigation BMP demonstration field (i.e., Moncur Field).

The Snake River Plain aquifer, underlying the eastern Snake River Plain, is hosted in layered basalts and interbedded sediments and is an integral part of the basin water resources. In some places, the flow of the Snake River is composed predominantly of aquifer discharge. Aquifer water levels and spring discharges increased through the first half of the century, but have been declining in the past several decades. The long-term changes are in response to changes in recharge and discharge associated with surface and groundwater irrigation. These changes are driving conjunctive management of surface and groundwater resources and the use of a numerical groundwater model to understand and help manage the aquifer. The University of Idaho and the Idaho Department of Water Resources developed a two-dimensional finite difference model of the Snake River Plain aquifer in the 1970s. That model has evolved into the model documented in this report. Most recently, the model has been adapted to use the U.S. Geological Survey's MODFLOW code and the domain has been expanded to include the northeastern part of the aquifer system. The model has been calibrated to a one-year period from April 1980 to March 1981. The transient calibration was conducted in two parts. The first part was the original model domain, calibrated by the Idaho Department of Water Resources. The second part, the area near and including the extended domain in the northeast, was calibrated by the University of Idaho. Extending the domain resulted in revisions to the model water budget and created a discrepancy between estimated recharge and discharge components. Further work should be performed to improve the model's reliability. Priority should be given to improving the conceptual understanding and quantitative behavior of the interaction with the Snake River.

This report documents another step in the evolution of this model. The most recent changes to the model include the conversion from a specially developed model code to the U.S. Geological Survey's MODFLOW code and an extension of the model domain to include the northeast corner of the Snake River Plain aquifer. Comparison of the simulation results for the April 1980 through march 1981 period verified that the conversion to MODFLOW did not change any significant features of the model and that the previous model generated reproducible results. The equivalent model adapted to the MODFLOW code allows for easier and wider use among scientists and facilitates application of commercial user interfaces and provides greater opportunities for model enhancement. Extension of the model domain to the northeast allows the inclusion of reaches of the Snake River that were previously not simulated. The introduction of 110 new model cells required that a localized calibration be performed that was consistent with the 1997 calibration of the previous model domain. A localized transient calibration was performed to the April 1980 through March 1981 period. The calibrated model replicated river gains and losses in the northeast portion of the model well; however, differences in simulated and measured aquifer heads were relatively large in some areas. Part of the difference is attributed to uncertainties in the estimates of initial aquifer head and inconsistencies with the understanding of river gains and losses.

The complexity of water allocation is magnified by the size of the basin and the varied types of interests competing for water. Irrigation interests, municipalities, flood control operators, tribal needs, industrial uses, domestic supply, recreation and species habitat requirements are all exerting demands on the water system. To enhance decision making abilities as related to water allocation, the United States Bureau of Reclamation initiated the Snake River Resources Review (SR3). The SR3 project involves all Snake River drainage areas upstream from Brownlee Dam, located on the Idaho Oregon border. In support of the SR3 study, this report addresses the groundwater surface water interactions between the tributary basins and Snake River. The entire study area was subdivided into geographic areas utilizing the hydrologic unit boundaries (HUCs) established by the U. S. Geological Survey (USGS). Data were accumulated to identify areas where groundwater use may be sufficient to materially impact surface water flow. The data sets include: (1) groundwater-rights (location, amount, priority date), (2) water table fluctuations, (3) agricultural land use, and (4) recorded stream flow measurements. Current rules for conjunctive management of the surface water and groundwater systems were also reviewed. Aquifers in much of the Snake River basin in Idaho have been modeled by previous efforts. In this study, individual HUCs were compared to one another utilizing the criteria suggested by the Idaho Department of Water Resources (IDWR) for prioritizing areas where additional or more detailed groundwater modeling should be performed. From this basin wide approach, 6 areas received a High Priority ranking: Teton, Raft, Big Lost, Big Wood, Portneuf, and Salmon Falls. Areas receiving a Medium Priority include Middle-Snake Succor, Bruneau, C. J. Strike Reservoir, Camas, and Blackfoot. Water table fluctuations observed in wells, measured by the USGS, indicate that not all wells in a given region show an equal response to stresses on the water system.

(2) \"Simulation of groundwater flow in the Boise Front geothermal aquifer (Zyvoloski et al., 2003). This study arose from a request by the City of Boise to expand current levels of production (with corresponding re-injection) under existing water right permits.

The proposed production increase led to concerns about possible water level and/or temperature changes in the geothermal system by other users. The City of Boise and other major users therefore sought additional hydraulic, thermal, and hydrogeologic information about the geothermal aquifer system, and the development and implementation of a monitoring plan. The purpose of this study was to provide insight and tools for the long-term management of the Boise geothermal aquifer system. Specific objectives included the following: (1) Review and refine the current conceptual understanding of the Boise Front geothermal aquifer system. (2) Consolidate existing hydrogeologic and production data into a single database. (3) Conduct a mass measurement of water levels and/or pressures in selected geothermal wells throughout the system.

Design Documents DDW-001, DDW-002, and DDW-005 through DDW-017 discuss various aspects of this calculation. Recharge on non-irrigated lands was calculated according to procedures presented in Design Document DDW-003. Knowledge of land use or cover was required to determine which calculation method to use, and to apply the appropriate parameters in calculating recharge. There are large differences in recharge rate, depending on the land use. Wetlands that are interconnected with the aquifer may result in a recharge of negative two feet per year or more (Goodell 1988), while other non-irrigated lands may have positive recharge of a few tenths of a foot (Garabedian 1992). Irrigated lands may have positive recharge rates of up to several feet. These large differences in recharge rate make it important to correctly identify the land use within the study area.

These minor-area lands were represented as separate polygons to which a fixed net recharge rate was applied. The outcome was a single GIS grid map per stress period, covering the entire plain and representing recharge for non-irrigated land use. In calculating the water budget, the recharge tool (comprised of a GIS component and a Fortran component) considered maps of irrigated lands and applied either the irrigated-lands recharge calculation or the recharge depth from the GIS grid map to appropriate areas of each model cell.

The purpose of flow augmentation has been largely to increase the velocity and/or reduce the temperature of water flowing through mainstem reservoirs in the lower Snake and Columbia Rivers. Although improved adult returns are generally associated with good water years (e.g., high natural flow and spill) during juvenile outmigration, the efficacy of flow augmentation as a substitute for good water years has not been defensibly established. During the period from 1995 through 1998, the National Marine Fisheries Service (NMFS), the U.S. Fish and Wildlife Service, and the Nez Perce Tribe investigated migration characteristics of hatchery-raised, subyearling fall chinook salmon (Oncorhynchus tshawytscha) in the Snake River Basin (Muir et al., 1999). Hatchery raised sub yearlings were used as surrogates for wild sub yearlings in the survival research. The studies showed that estimated survival from points of release to the tailrace of Lower Granite Dam could be correlated with all three environmental variables examined (flow rate, water temperature, and turbidity). Estimated survival decreased throughout the season, as flow volume and turbidity decreased and water temperature increased (Muir et al., 1999). These correlations have provided the primary basis for the continuation of flow augmentation from reservoirs in the Snake River and Clearwater River Basins (NMFS, 1999). The purpose of this report is to provide a review of the data considered in the Muir et al. (1999) study within the context of determining the efficacy of flow augmentation for enhancing the survival of subyearling fall chinook. In particular, relationships between flow rates, water temperatures, travel times, and estimated survival of hatchery-raised, subyearling fall chinook salmon between points of release and detections at Lower Granite Dam are examined. This report includes analyses of: (1) flow rates and water temperatures at Lower Granite Dam; (2) estimated survival with 5th percentile flow indices; (3) estimated survival and 5th percentile water temperature indices; (4) estimated survival versus release dates; (5) estimated survival versus release groups; and (6) fall chinook travel times and numbers of detections. Finally, these comparisons are used to draw conclusions about flow rates, travel times, subyearling survival, and effectiveness of flow augmentation.", "publisher": "Idaho Water Resources Research Institute, University of Idaho", "contributing-institution": "University of Idaho", "source": "Idaho Water Resources Research Institute, University of Idaho", "identifier": "IWRRI Number 200003", "language": "eng", "rights": "In copyright, educational use permitted.

To accomplish this, spatial distributions of key hydrochemical parameters were analyzed with respect to aquifer stratigraphy. Occurrence of tritium (3H) in most of the groundwater samples taken from the upper 200 to 300 feet of stratigraphic section near the NYC provides strong evidence of rapid recharge of Snake River Group aquifers. groundwater residence times range from several years in shallow, perched aquifers adjacent to the canal to approximately 100 years in deeper, confined, or semi-confined aquifers. Elevated concentrations of nitrate (NO3) and carbon dioxide (CO2) in aquifers underlying irrigated fields west of the canal demonstrate the effect of flood-irrigation on groundwater recharge. groundwater in aquifers east of the canal do not underlie irrigated land and do not exhibit elevated concentrations of NO3 and CO2. A groundwater divide directly beneath the canal appears to minimize mixing of these waters. Lack of 3H and NO3 and an abrupt decrease in conductivity (Cs) in groundwater from wells that penetrate thick, blue clay layers at approximately 2,400 feet below mean sea level suggests that these aquifers do not receive substantial recharge from overlying groundwater. Previous analysis of groundwater ages suggest that these aquifers contain paleo-water and are part of a much larger, regional groundwater system.

Final model documentation will include all of the design documents, edited to ensure that the \"as-built\" condition is appropriately represented. This is the final as-built document describing determination of the source of irrigation water. Recharge from surface-water irrigation is the largest component of aquifer recharge, and a large source of model uncertainty. The second-largest component of aquifer discharge is net withdrawals (calculated as consumptive use, or evapotranspiration) due to groundwater irrigation. The source of water for individual parcels must be identified so that diverted volumes of surface water are applied to the appropriate spatial locations. The source of water also affects the calculation of consumptive use, which depends in part on evapotranspiration (ET) adjustment factors, application method (sprinkler or gravity), and the reduction factor for non-irrigated inclusions within irrigated lands. For an individual parcel, the ET adjustment factor and sprinkler percentage from the local surface-water irrigation entity or the local groundwater irrigation polygon are applied, depending on the water source identified for the parcel. The reduction factor assigned is a weighted average of the sprinkler and gravity reduction factors, depending on the sprinkler percentage assigned to the parcel. Assigning these parameters for calculation purposes requires information on the water source for the individual parcel. An additional need to identify the source of irrigation by parcel is in use of the model, when a hypothetical scenario representing curtailment of irrigation may be tested. Many irrigated lands are either 100 percent surface-water irrigated or 100 percent groundwater irrigated. However, some irrigated lands have mixed groundwater and surface water sources. This has typically occurred where surface water sources were inadequate, and supplemental groundwater sources have been developed. This paper describes the method used to determine the source of irrigation water, the method used to calculate recharge on mixed-source lands, and the potential effects of errors in determining the mix ratio.", "collection": "Boise Basin", "series": "ESPAM", "publisher": "Idaho Water Resources Research Institute, University of Idaho", "contributing-institution": "University of Idaho", "source": "Idaho Water Resources Research Institute, University of Idaho", "identifier": "IWRRI Number 2004010", "language": "eng", "rights": "In copyright, educational use permitted.

In other cases the aquifer bottom is defined by gradual changes in material properties. An example of this for the Snake Plain Aquifer might be diagenetic alterations within the basalts gradually reducing permeability as the older and deeper basalts age.

The purpose of this model is to assist in managing the surface water and groundwater resources within the Eastern Snake Plain Aquifer and the Snake River. Therefore the model boundaries should encompass the boundaries of the Eastern Snake Plain aquifer. Decisions regarding where to place the model boundary must be made where the Eastern Snake Plain aquifer interfaces with tributary aquifers. These decisions should be based on the model purpose and data availability. Extending model boundaries to bedrock outcrops in tributary basins allows incorporation of seasonal and long-term changes into the model simulation rather than estimating them external to the model. Extending the boundaries to Include land with similar irrigation practices is desirable, if the resulting boundary does not cross a hydrologic barrier.

This document discusses whether the Eastern Snake Plain Aquifer will be represented as a confined or an unconfined aquifer. The decision to use state-of-the-art parameter estimation techniques makes this decision more difficult. The existing IDWR/UI aquifer model (Cosgrove et al, 1999) uses an unconfined representation for the Eastern Snake Plain Aquifer and Garabedian (1992) employed an unconfined representation also. Thus, a choice of an unconfined representation for the Eastern Snake Plain Aquifer would be consistent with tradition. However, a confined aquifer model representation requires fewer computations and behaves more stable numerically than an unconfined aquifer representation. These two factors present significant advantages when using parameter optimization tools that run the model thousands of times to select a parameter suite that minimizes the differences between observations and modeled values.", "collection": "Boise Basin", "series": "ESPAM", "publisher": "Idaho Water Resources Research Institute, University of Idaho", "contributing-institution": "University of Idaho", "source": "Idaho Water Resources Research Institute, University of Idaho", "identifier": "IWRRI Number 2004020", "language": "eng", "rights": "In copyright, educational use permitted.

Final model documentation will include all of the design documents, edited to ensure that the \"as-built\" condition is appropriately represented. Calculation of net recharge from surface-water irrigation and calculation of net discharge from groundwater irrigation require estimates of crop evapotranspiration (ET). The details of the calculations proposed for the Eastern Snake Plain Aquifer Model Enhancement Project are discussed in Design Document DDW-002. The calculations involve diversion volumes that are large relative to the overall aquifer water budget. The proposed calculations are: (1) Field Delivery = Diversions - Canal Leakage - Return Flows (2) Net Recharge (surface)= (Field Delivery + Precipitation) - (ET x Adjustment Factor) (3) The calculation for net recharge from groundwater irrigation (typically a negative recharge, or net withdrawal) is: Net Recharge (ground) = Precipitation - (ET x Adjustment Factor). These are commonly used and accepted methods (Burt 1999) and are the methods used by the US Geological Survey (Garabedian 1992) and Idaho Department of Water Resources (1997) in former Snake Plain modeling efforts. The ET adjustment factor is an innovation added in this effort to accommodate differences between potential and actual crop conditions. ET adjustment factors are discussed in Design Document DDW-021. Calculation of recharge on irrigated lands will include a consideration of antecedent soil moisture and available irrigation diversions, to allow reduction of ET when water supplies are reduced. This helps avoid under-predicting recharge on surface-water irrigated lands, and avoids over-predicting extraction on groundwater irrigated lands. This paper describes the data sources and methods proposed for determining the basic ET rate for these calculations. Evapotranspiration is controlled by climate as well as crop and soil characteristics. Climate affects the evaporative power of the atmosphere, reflecting the capacity of air to accept evapotranspired water and the energy available to drive evapotranspiration. Soil and plant characteristics control the crop's ability to extract water from the soil, and biological characteristics of the crop that control the transpiration response to evaporative power. Soil texture, surface wetness and condition and shading by crop plants control the soil's evaporation response to evaporative power. Final as-built.

Final model documentation will include all of the design documents, edited to ensure that the \"as-built\" condition is appropriately represented. In the Eastern Snake Plain Model Enhancement Project, the basic equation for calculating net recharge from irrigated agriculture is: (1) Net Recharge = (Field Delivery + Precipitation) Evapotranspiration (ET) (2) Where Field Delivery = (Surface Water Diversions Returns Canal Leakage). The base ET in equation (1) will be calculated as described in Design Document DDW-010. When the water source is groundwater, surface water diversions are zero and the calculated net recharge is negative (net withdrawal). These are commonly used and accepted methods (Burt 1999) and are the methods used by the US Geological Survey (Garabedian 1992) and Idaho Department of Water Resources (1997) in previous Snake Plain modeling efforts. In the recharge tools of the model enhancement project, ET is expressed first as a depth, then multiplied by irrigated area within each model cell to obtain a volume of ET. Various conditions have the potential to alter the actual field ET depth from the wellwatered- disease-free condition represented by typical planning ET calculations and tables. The actual consumptive use depth may also be different than calculated ET if there are consumptive fates for diverted water other than those contemplated by equations (1) and (2). Finally, the actual volume of ET calculated can be affected by bias in the data used for irrigated area within each model cell. If these differences can be identified and quantified, an ET adjustment factor may be applied to correct the calculation of net recharge: (3) Net Recharge = (Field Delivery + Precipitation) (ET x Adjustment). The recharge tools allow for two ET adjustment factors per groundwater entity or surfacewater polygon, one for sprinkler application and one for gravity application. These potentially could be adjusted by the PEST software during parameter estimation. This Design Document explores the conceptual basis for ET adjustment factors and describes the proposed approach to calculate these factors.", "collection": "Boise Basin", "series": "ESPAM", "publisher": "Idaho Water Resources Research Institute; University of Idaho", "contributing-institution": "University of Idaho", "source": "Idaho Water Resources Research Institute; University of Idaho", "language": "eng", "rights": "In copyright, educational use permitted.

The aquifer system lies within the Boise Front groundwater management Area. Proposed increases in thermal water use have led to concerns about potential long-term impacts to the geothermal aquifer system, and the ability of current aquifer monitoring to detect possible changes. The purpose of this study was to provide insight and tools for the long-term management of the Boise geothermal aquifer system. Specific objectives included (1) conducting a mass measurement (i.e., \"simultaneous\" measurement of numerous wells over a short period of time) of water levels and/or pressures in the geothermal wells, (2) developing a relational database using existing data, (3) reviewing hydrologic conditions in the aquifer, and (4) constructing a numerical model to simulate aquifer productions. The primary areas of interest for this study included the Harris Ranch, downtown Boise-Table Rock, and Stewart Gulch areas. This report provides a summary of hydrogeologic conditions in the geothermal aquifer system. A description of numerical model construction and simulations results are presented in a separate volume (Zyvoloski et al., 2003). [...] The downtown Boise-Table Rock and Stewart Gulch areas have experienced a number of water level decreases and increases since the early 1980s. Despite these observations, it is not possible to conclude that there has not been water level response in the Stewart Gulch area from geothermal withdrawals in the downtown area, or vice versa. Conceptually, faulting along the Boise Front would provide a basis for hydraulic connections between these areas. Although geothermal water in these areas has different chemistry characteristics and residence times (Mariner et al., 1989), the water shares a common source (Idaho Batholith granitics). It is conceivable that stresses from the downtown area could influence water levels in the Stewart Gulch area, or vice versa, depending on the magnitude and duration of the stress.

The Eastern Snake River Plain Aquifer Model (ESPAM) has been updated to version 1.1, and the results of re-running the Curtailment Scenario with the updated model are presented here. The Curtailment Scenario is one of many Snake River Plain aquifer model scenarios being developed to assist in resolution of conflicts among water users and guide future water management such as implementation of managed recharge. Water management should be guided by a collective perspective from many of the scenario evaluations rather than a single document. The present version of the ESPAM was developed with funding provided by the State of Idaho, Idaho Power Company, the U.S. Geological Survey, and the U.S. Bureau of Reclamation. The model was designed with the intent of evaluating the effects of land and water use on the exchange of water between the Snake River Plain aquifer and the Snake River. This evaluation is part of the application of the model towards this purpose. This \"Curtailment Scenario\" is intended to answer the question \"If all groundwater rights with priorities after a specified date were to be curtailed, what would the effect be on spring discharge and Snake River gains and losses?\" This set of scenario simulations assesses this question for groundwater rights with priorities junior to the following dates: a) the onset of groundwater irrigation (1870) b) January 1, 1949 c) January 1, 1961 d) January 1, 1973 e) January 1, 1985. The underlying theory of this set of scenario simulations is that if all groundwater rights junior to a certain priority date were to be curtailed, benefits would be accrued to the river gains and spring discharges from the eastern Snake River Plain aquifer. These simulations illustrate the model-predicted increases in river gains and spring discharges over time. Benefit to river gains could be in the form of increased aquifer discharge to the river, decreased losses from the river to the aquifer or increased spring discharge from the aquifer. Future reference to increased river reach gains in this report will include all three of these cases.", "collection": "Boise Basin", "series": "ESPAM", "publisher": "Idaho Water Resources Research Institute, University of Idaho", "contributing-institution": "University of Idaho", "source": "Idaho Water Resources Research Institute, University of Idaho", "identifier": "IWRRI Number 200601", "language": "eng", "rights": "In copyright, educational use permitted.

For example, in the eastern Snake River Plain, estimates of evapotranspiration (ET) were used to represent the consumptive portion of groundwater irrigation pumping in calibration of an aquifer model, and in applications of that model to determine effects of pumping upon spring discharge (Cosgrove et aI., 2006). ET estimates are often used in water balance analyses to help determine lesser-known components such as aquifer recharge. Remote sensing can be a valuable tool in estimating evapotranspiration on large scales due to the high areal variability of ET and the difficulty of obtaining crop-mix data for large areas. In previous work, algorithms such as METRIC (Allen et aI., in press, a; Allen et aI., in press, b) and SEBAL (Bastiaansen et aI., 1998) have made use of the thermal band data of satellites such as LANDSAT in energy-balance calculations of ET. However, the continued use of these tools is in jeopardy due to the planned discontinuation of distribution of the thermal band of data from LANDSAT (Allen, 2005 a). Additionally, SEBAL and METRIC require significant expertise and processing time, and rely upon operator selection of \"hot\" and \"cold\" pixels. The purpose of this project was to develop and evaluate alternative means of determining the magnitude and areal distribution of irrigated ET, using visible and near-infrared bands from LANDSAT. The goal of this effort was to identify methods that are: 1. not reliant on thermal-band data, 2. low cost, 3. easily applied and, 4. objective and repeatable.", "collection": "Boise Basin", "publisher": "Idaho Water Resources Research Institute; University of Idaho", "contributing-institution": "University of Idaho", "source": "Idaho Water Resources Research Institute; University of Idaho", "language": "eng", "rights": "In copyright, educational use permitted.

The Eastern Snake Plain aquifer consists of a series of basalt flows with interlayered pyroclastic and sedimentary material. It extends across southern Idaho in a swath about 170 mi long and 60 mi wide. The Eastern Snake Plain aquifer encompasses the broad depression extending from King Hill in the southwest to Ashton in the northeast. Its lateral boundaries are formed by contacts with less permeable rocks at the margins of the plain.Numerous investigators have modeled all or parts of the Eastern Snake Plain aquifer. Two models of particular interest include one constructed by The University of Idaho for the Idaho Department of Water Resources (IDWR) described in Cosgrove and others (1999) and one by the U.S. Geological Survey (Garabedian, 1992). The Garabedian model was constructed largely as an investigative tool to explore concepts of regional groundwater flow and improve scientific understanding of the aquifer. The IDWR model was designed primarily as an aquifer planning and management tool. The modeling effort this document supports, the Eastern Snake Plain Aquifer Model Enhancement Project, was undertaken to facilitate conjunctive management of the Eastern Snake Plain aquifer. Thus, the model must necessarily represent both the Snake River and the Eastern Snake Plain aquifer as accurately as possible. The modeling process includes establishing calibration targets, identifying adjustable parameters, and quantifying known model inputs. For this effort, the calibration targets include aquifer water levels and Snake River reach gains and losses. The adjustable parameters include aquifer transmissivity, specific yield, and riverbed and drain conductance. The known inputs include precipitation, evapotranspiration, surface water irrigation, groundwater pumping, seepage from rivers other than the Snake River, and underflow from tributary aquifers.", "collection": "Boise Basin", "series": "ESPAM", "publisher": "Idaho Water Resources Research Institute; University of Idaho", "contributing-institution": "University of Idaho", "source": "Idaho Water Resources Research Institute; University of Idaho", "language": "eng", "rights": "In copyright, educational use permitted.

This evaluation is part of the application of the model towards this purpose. The model was developed by the Idaho Water Resources Research Institute (IWRRI) under the guidance, and with the participation, of the Eastern Snake Hydrologic Modeling Committee (ESHMC). The effort was led by the Idaho Department of Water Resources (IDWR) and active participants in the Committee included Idaho Power Company, the U.S. Geological Survey, the U.S. Bureau of Reclamation, and IWRRI. The ESHMC has also served to guide and review the scenario evaluation process. Documentation of the model and related activities are available from the Idaho Department of Water Resources and the Idaho Water Resources Research Institute at the University of Idaho. This scenario, Hydrologic Implications of Continued Drought and Potential Recovery from Drought, is intended to answer the questions: \"What is the expected magnitude of impacts to the Snake River and springs if the drought continues?\" and \"How rapid might recovery be when the drought ceases?\" The modeling results predict the spatial and temporal distribution of the hydrologic impacts to springs and rivers from three different synthetic drought and recovery regimes. bDRAFTThis scenario, Hydrologic Implications of Continued Drought and Potential Recovery from Drought, (also known as the \"Drought Scenario\") is one of many simulations using the Snake River Plain aquifer model to provide information and assist in resolution of conflicts among water right holders and guide future water management such as implementation of managed recharge. The purpose of the Drought Scenario is to provide context for the other scenarios, which largely examine anthropogenic stresses to the aquifer, Snake River and springs. All the scenarios use the revised Snake River Plain aquifer model to predict hydrologic response to various hypothesized aquifer stresses.

This practice has been called \"soft conversions.\" Soft conversions are attractive on a practical basis because more of the infrastructure to deliver surface water to the parcels may already be in place. They are attractive administratively because surface-water irrigation rights, often with relatively senior priority dates, are already in place. The legal authority and ability to deliver water to these lands is more certain than for other uses of water that may benefit the aquifer. When additional surface water is delivered to soft conversions, the benefit is essentially doubled; the first benefit is that groundwater pumping for irrigation is reduced, and the second benefit is that incidental recharge from surface-water irrigation is increased. [...] The study addressed four fundamental questions: (1) How many of these mixed-source parcels (parcels with both surface-water and groundwater rights) are actually supplied only from groundwater? (2) What is the degree and cost of infrastructure improvement needed to deliver surface water from existing canals to these parcels?

This will provide additional documentation of project history and the development of ideas. The ESPAM 1.1 model was calibrated in 6-month stress periods over the 1980-2001 period and model results were matched to both long term and seasonal variations in aquifer head and Snake River gains and losses. All recharge and discharge events and river stage are assumed constant for the length of a stress period, although aquifer heads may be computed at more frequent time steps. In ESPAM 1.1, the stress periods were selected as May through October (higher recharge irrigation season), and November through April (lower recharge non-irrigation season). Recharge and discharge data for each stress period are assembled and processed in the GIS-Fortran based Recharge Program which will work on stress periods of different lengths. In most cases recharge and discharge data and stream stage are available at a higher frequency than semi-annual periods. During model calibration the outputs of aquifer head and river gains and losses are compared to measured or estimated values. Estimates of the aquifer properties of transmissivity (or hydraulic conductivity) and storativity are adjusted to achieve a good fit between simulated and measured values. These property estimates subsequently control model results in simulations performed to guide aquifer management and administration. A more accurate description of recharge and discharge and river stage as model input should result in a better fit to historic measured values and improved calibration of aquifer properties, ultimately generating greater reliability of management and administrative simulation results. Since recharge, discharge, and river stage must be assumed constant during a stress period, it would seem that the shorter the stress period the more accurate the representation of reality. This is true to the extent that a) data are collected at short intervals, and b) there are not unknown or unrepresented elements of storage or lag in the system.", "collection": "Boise Basin", "series": "ESPAM2", "publisher": "Idaho Water Resources Research Institute, University of Idaho", "contributing-institution": "University of Idaho", "source": "Idaho Water Resources Research Institute, University of Idaho", "identifier": "IWRRI Number 200807", "language": "eng", "rights": "In copyright, educational use permitted.

(2008) developed response function maps and a spreadsheet tool for assisting water interests with assessing surface water impacts resulting from changes or proposed changes in aquifer recharge or discharge. The response functions were calculated using the SVRP aquifer model developed by Hsieh et al. (2007). Those response function products are valid so long as surface and groundwater interaction respond in a near linear fashion. The purpose of this report is to describe the potential error in SVRP response functions that results from linear approximations to non-linear conditions represented in the SVRP aquifer model developed by Hsieh et al.

As discussed in analysis for ESPAM 1.1, Design Document DDW-024 (Erickson, Nelson, and Contor, 2004) some streams in the Snake River Plain that are perched are believed to be hydraulically contributing to the aquifer because of seepage. This design document describes perched river seepage from streams and other water bodies in the Eastern Snake Plain. Some surface water bodies that are represented in ESPAM 1.1 as perched are likely connected to the aquifer, which includes Mud Lake and parts of the Big Lost River and Camas Creek. These were not represented as hydraulically connected because simulating impacts to those water bodies was not part of the purpose of ESPAM 1.1. Because these are tributary to the regional aquifer, this doesn't change the water balance nor does it materially change the propagation of impacts to the Snake River or springs. These water bodies (Mud Lake, parts of the Big Lost River and Camas Creek, part of Twin Falls Canal, and Lake Murtaugh) will be simulated the same as they are in ESPAM 1.1 and will therefore not be discussed in this design document.
