An unsteady three-dimensional non-hydrostatic model is used in this paper to predict the hydrodynamics and thermal dynamics in the forebay and turbine intakes of McNary Dam. The flow field in the forebay was unsteady and highly three-dimensional due to the influence of the dam structures, reservoir bathymetry, and dynamic atmospheric conditions. The summer flow objective for Lower Granite Dam is based on the June Final water supply forecast. WSU Prosser - IAREC, 24106 N Bunn Rd, Prosser WA 99350-8694, 509-786-2226. At The Dalles Dam, the addition of a spill wall and changed spill patterns has decreased adult fall back (although this was a beneficial side effect of other efforts). This project would make available meaningful volumes of water for instream and out-of-stream uses in the McNary Dam Pool on the Columbia River, both upstream and downstream of the Reservoir.

Facilities requiring potable water included the McNary Lock and Dam powerhouse, two machine-shop and warehouse buildings, a yard fire suppression system, and two outdoor park restrooms. The ASFM uses a technique called acoustic scintillation drift (Farmer & Clifford, 1986) to measure the flow speed of water perpendicular to a number of acoustic paths established across the intake to the turbine. Warm water created lethal conditions for cold-water fish species resulting in one of the worst seasons for Snake River sockeye salmon. tle Goose Dam on the Snake River and hauling them by truck to release sites below Bonneville Dam, the dam furthest downstream on the Columbia (Fig. McNary Dam and Lake Wallula McNary Lock and Dam was authorized by Congress for power and navigation in the 1945 Rivers and Harbors Act. End of turning pool 2, the count station is above the weir. The research objectives at each dam were as follows: McNary Dam - Conduct a pilot study of simultaneous fish behavior and water velocity data in the residential uses of water. The project was originally called the Umatilla Dam, but the River and Harbor Act of 1945 renamed the dam in honor of the late Senator Charles L.
