A tight fit. The clearance between the huge 25-foot rotors and the stators of the two 75,000 kilowatt Shasta Dam generators, being installed at Grand Coulee Dam to make additional power available for war industries, is only 5/8 inch. Lowering this 450 ton wheel into place, the operators of the two powerhouse cranes, that jointly supported the load, were guided by workmen, stationed around the rim, who inserted sticks between the stationary and moving parts to measure the clearance and prevent contact. When the unit goes into service next February, the outer rim of this rotor, which is 7 feet high, will spin at 125 miles per hour. Attached to the rim are 52 magnets, weighing 3300 lbs. each.
The 190-ton scroll case for 103,000 horsepower Allis-Chalmers hydro turbine unit being installed in the west powerhouse at Grand Coulee Dam. This unit consists of several radial and on straight section of welded plate steel riveted with double butt straps. One half of combined unit is lifted by an overhead crane and moved into position. Before being poured in concrete, the scroll case is given hydraulic test of 310 pounds to the square inch. This scroll case, designed for use at Shasta Dam in northern California, is temporarily installed at Grand Coulee Dam by order of the War Production Board, as construction at Shasta Dam had not progressed sufficiently to make immediate use of turbine at that point. With the waters of the mighty Columbia River as a driving force, this turbine now installed is spinning a giant generator at a rate of 138.5 revolutions per minute, producing more than 75,000 kilowatts of electrical energy.
A view of the east end of the left powerhouse, with turbine pit No. 6 in the immediate foreground
Col. Basin Proj., Grand Coulee Dam.--Lowering the turbine runner for the No. 1 Shasta Dam generator, of 75,000 kw. Capacity, moved to Grand Coulee Dam with another machine of like size to expedite delivery of new power to Pacific Coast war industries. The wheel is seen as it is entering the well at el. 979. The weight of the runner with its 41 1/2' shaft is about 85 tons.
Bolts and nuts weighing 193 pounds, couple the sections of the shafts for the two 75,000 kilowatt Shasta generators being installed in the Grand Coulee Dam left powerhouse. The bolts are five inches in diameter and 25 inches long. Each section of the two part shaft is provided with a flange, in which 16 holes have been bored. The bolts will be inserted in these openings, and the nuts, weighing 37 pounds each, attached. To tighten these, a huge steel wrench, three feet long, turned by the blows from a heavy sledge hammer, will be used. Before being seated, the bolts will be cooled to 80 below zero, and shrunk, in a compartment filled with dry ice. While in their contracted form, they will be inserted in the openings in the flanges of the shaft. When their temperature again rises and matches that of the surrounding atmosphere, the fit will be as near perfect as engineers are able to make it.

Needle valve being lowered to base in R-8 of East Powerhouse
An 84-inch needle valve being placed on erection base in bay R-5 of the right powerhouse at Grand Coulee Dam. Eight of these needle valves, transferred from Boulder Dam, are being temporarily installed in the turbine pits by use of steel reducers (elbows) joining the valve with the 18-foot in diameter penstock tubes. A portion of the stream flow of the Columbia River is to be passed through those needle valves during the low water season. The flow through the needle valves, in addition to that portion of the river flow passing through the turbines in the left powerhouse will make unnecessary the use of the spillway. This program of diversion will provide a minimum of turbulence in the water at the foot of the spillway section, facilitating future repair work to the concrete bucket or trough at the base of the spillway. At some future date, the needle valves will be replaced by 150,000 horsepower hydro-turbines, designed to propel 108,000 kilowatt hydroelectric generators.

41 degree, cast steel elbow, installed between penstock reducer section and needle valve in bay R-9 of the right powerhouse at Grand Coulee Dam. Eight needle valves, each having an 84-inch discharge, are being installed in the right powerhouse. The portion of the Columbia River stream flow not used through the turbines in the left powerhouse, is to be passed through the needle valves installed in the right powerhouse during the low water season. This plan will eliminate the use of the spillway during certain months of the year, assuring a minimum of turbulence in the water downstream from the dam, to facilitate necessary repairs to the concrete spillway bucket.

Columbia Basin Project, Irrigation Division, Long Lake Dam. Assistant Resident Engineer, Donald B. McLaren checking fill moisture by the use of a proctor plasticity penetrometer. Representative material from the spread and processed lift is obtained, given standard laboratory compaction and resistance to penetration of a needle of definite end area is measured. A resistance to penetration range from 1000 to 2000 pounds per square inch indicates that the material contains the proper moisture for compaction. A needle reading less than 1000 pounds per square inch indicates that material is too wet and must be dried out by processing or mixing with drier material. A needle reading greater than 2000 pounds per square inch indicates that the material is too dry and moisture must be added. Harold Foss, photographer.

This aerial view of the Grand Coulee Dam area shows the status of progress on the construction of Grand Coulee pumping plant and feeder canal. The pumping plant is being constructed behind the 600-foot long wing dam extending to the left from near the west abutment end of Grand Coulee Dam. The world's largest pumps will be installed in the pumping plant at a level of 120 feet below the roadway elevation. Each pump will lift water 280 feet from Roosevelt Lake and will discharge it through a steel pipe 12 feet in diameter and about 680 feet in length. Twelve tunnels, from 487 to 530 feet in length, will carry the pipes under the highway and up through the granite canyon wall. Upon emerging from the tunnels, as do the three pipes on the right, they will continue on concrete piers for about 260 feet and discharge into the headworks for the feeder canal. Excavation of the feeder canal has been completed to the cut-and -cover section and is ready for concrete lining.

Approximately 750,000 tons of granite will be used to loop the banks of the Columbia River below Grand Coulee Dam, protecting the shores against the 10-million horsepower in energy which the waves spent after their 350-foot fall over the dam. Above, 20-yard Euclid truck, with two motors and powered steering wheel, dumps a couple of big ones.
Although this truck alone weighs almost 60,000 pounds, it's not uncommon for one or two huge granite armor rocks to lift the front wheels clear of the ground. A dozer, blade visible at left, solved the truck drivers dilemma in this problem. The trucks can carry 20-30 tons, and sometimes one rock is an entire load. Approximately a year and one-half will be required to line the banks for close to one mile downstream from the Grand Coulee Dam.

The new Interstate Highway 80 bridge that will span the entrance to the artificial bay that will be created by the U.S. Army Corps of Engineers' John Day Dam Reservoir on the Columbia River at Arlington, Oregon, will be placed in use in June 1965. Shown in the lower part of the picture is the 15-acre newly prepared business section created by the artificial fill to elevation above the reservoir. The buildings in the center of the picture are not scheduled for demolishing until May 1967; however, access to the present temporary business district will be practically cut off once traffic is diverted across the new Interstate 80 bridge. With creating the John Day reservoir, the water will inundate the present temporary business section occupied by the buildings, and the new Arlington will be provided with a quay-type waterfront. The huge fill riverward is being used as a disposal center for rock and earth being removed in the grading of Interstate Highway 80 along the south-shore cliffs.
A few miles above the south shore axis of the U.S. Army Corps of Engineers John Day Lock and Dam on the Columbia River, the newly relocated Interstate Highway 80N and the Union Pacific transcontinental main line swing across the John Day River. Here is shown the new four lane highway bridge at John Day and the new Union Pacific Bridge necessitated by the relocation work. Riverward from the two new crossings may be seen the old highway bridge and the Union Pacific bridge as they cross the John Day River at the present Columbia River level. Both of these approaches will be inundated with the creation of the John Day reservoir.

Bulldozer Jockeys have a special technique for flood fighting. It is a double action procedure of moving their equipment out into the flood stream bed and with the bulldozer blade widening the stream channel, at the same time pushing the blade load into a shore line embankment. Here is shown a bulldozer operation on the Walla Walla River in the Milton-Freewater area during the recent January flood. The channel widening, bank shoring processes can be visualized from the picture.
A fair-sized acreage of logs, trash, and shore debris marks the 1964 spring runoff hazard at Ice Harbor Dam on the Snake River. The trash and debris are slowly worked towards the disposal tram which carries the debris to high ground for burning. In with this trash are some million or so board feet of commercial saw logs swept downstream when a Clearwater River log boom broke during high water. The private tug in this picture is attempting to pick out these logs for salvage.

Cat jockeys must know their stuff in preparing the tunnel portal at the U.S. Army Corps of Engineers' Dworshak Dam on the North Fork of the Clearwater River. Here the two Bulldozers push over the cliff the results of a fair-sized blast at the tunnel portal. In the rear may be seen the battery of air drills constantly at work at the tunnel site.
The old business district of the town of Arlington, Oregon, still remains intact, but time is fast running out. The overpass bridge of Interstate Highway 80N is scheduled for completion by the end of the year. By that time the Walla Walla district, U.S. Army Corps of Engineers will have underway the demolishing phase of the project. The present Arlington business district will be transferred to the new site above the pool level of John Day Dam, scheduled for raising in 1968.
Shown here is the town of Boardman on the left side of the picture, showing U.S. Highway 30 to the upper or south of the picture. At the lower left hand corner of the picture may be seen the Union Pacific Railroad right of way. The entire town of Boardman will be moved from this site to a site at the upper left hand side of this picture near the dark area. The new interstate highway 80N will run by the darkened area, with Boardman being in between the new highway and the new railroad right of way, which will be approximately where U.S. highway 30 is now.

Looking downstream on the Columbia River, with Mount Hood in the background, is the U.S. Army Corps of Engineers John Day Lock and Dam. Work on the South or left shore, being carried on behind the 25-acre cofferdam enclosed work area, is nearing the 45 percent completion mark. Here the powerhouse and powerhouse intake section is being constructed, with a total of 578,000 cubic yards of concrete having been placed to date. Meanwhile, the entire flow of the Columbia River is being diverted through the 18 spillway bays while barge navigation is maintained through the North Shore navigation lock by use of a temporary channel feeding into the lock from upstream.
The U.S Army Corps of Engineers' John Day Lock and Dam South Shore Powerhouse section is well past the 40% completion mark under the $73, 356,000 contract held by Vinnell-McNamara-Mannix-Fuller. This picture was taken from the deck of the mid river spillway section of the dam, looking down into the 25-acre South Shore work area.
A battery of high gantry cranes carries on the work of placing the monthly average of over 70,000 cubic yards of concrete into the powerhouse structure at the U.S. Army Corps of Engineers' John Day Locke and Dam on the Columbia River. Vinnell-McNamara-Mannix-Fuller, holders of the $73 million contract for completion of the powerhouse section, is rated as over 41% complete and is on schedule.

Artist's conception of the $210,000 Dworshak Dam two miles upstream on the North Fork of the Clearwater river from the town of Ahsahka, Idaho. Dworshak Dam will be a concrete gravity dam with an initial power production potentially of 400,000 kilowatts from three generators. Three additional generators can be added later to boost the power output to 1,060,000 kilowatts. Dworshak dam will create a reservoir storing 3,454,000 acre-feet of water and will add substantially to the prime power production of hydroelectric plants downstream on the Snake and Columbia Rivers. Also, it will serve a vital role in flood control on the Clearwater, which has wide fluctuations in flow during the year. The Dworshak reservoir will be approximately 53 miles long. Congress appropriated $600,000 in planning funds in 1961 and in 1962 Congress appropriated $2,000,000 in construction funds. Start of construction began April, 1963, with building of access roads to the project.
Fifty-foot high, four decked jumbo drill rig that will be used to bore the diversion tunnel at the U.S. Army Corps of Engineers' Dworshak Dam on the North For Clearwater River. Thirty air-driven "Swedish ladder drills" will be distributed along the face of the mobile drill rig and will be advanced forward yard by yard as the tunnel bore is pushed ahead. The schedule calls for the thirty borings across the face of the tunnel to be loaded with explosives, the drill frame pulled back out of the tunnel, and the charge exploded at each change of shift. The bore will be 1,573 feet in length, with a vertical height of approximately 50 feet and a horizontal width of 40 feet.

In addition to a fleet of trucks, the Guy F. Atkinson Company of San Francisco, California, holder of the first stage construction contract at the U.S. Army, Corps of Engineers' Little Goose Lock and Dam site, has assigned two work barges with tugs. The fabrication of the cofferdam cells riverward from the work area behind which the Little Goose Dam will be constructed, is being carried on the high ground of what was once Little Goose Island. The barges and tugs are necessary to transport equipment from the south shore to Little Goose Island, where the cofferdam cell fabrication is underway. With completion of the cells, the Snake River will be diverted by an earthen embankment towards the north-shore, where and excavated diversion channel has been created.
