Hydroacoustic Evaluation of a Prototype Surface Collector and In-Turbine Screens at Bonneville Dam Powerhouse 1 in 2000
This study was one of many investigations of the U.S. Army Engineer District, Portland, to resolve critical uncertainties in the implementation of surface-collector technologies at Bonneville Dam. This research tested the efficiency of a six-unit version of the Prototype Surface Collector (PSC) and implementation of extended-length submersible bar screens at the dam's Powerhouse 1. The PSC slot configuration for 2000 consisted of a constant 20-ft- wide slot width for all six PSC units. The primary effects evaluated were weekly changes throughout spring and summer in a variety of juvenile fish passage measures, including numbers passing into and under the PSC, efficiency, effectiveness, diel patterns, and horizontal and vertical patterns of distribution. Detailed statistical methods are presented.
