The relation between streams and ground-water flow systems within the Pullman-Moscow Area of Washington and Idaho Item Info

A three-dimensional computer model of ground-water flow in the Pullman-Moscow area of Washington and Idaho was constructed in 1987 to address concerns over increasing pumpage rates and declining ground-water levels in the Grande Ronde Formation of the Columbia River Basalts. An integral part of the model is the interconnection of ground water and surface water. Streamflow measurements from a 1984 USGS survey suggest that a significant amount of ground water 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 ground-water discharge/recharge is occurring. Stream temperature surveys and geologic cross sections were used to identify and describe possible ground-water discharge areas. Results of the study suggest that sedimentary deposits located along the eastern terminus of the Roza Member of the Wanapum Formation are a source for ground-water discharge along Union Flat Creek, the North Fork of the Palouse River, and Four Mile Creek. Knowledge of the spatial and areal extent of the ground-water discharge zones will increase the accuracy of the Pullman-Moscow ground-water-flow model.
