Available in PDF, EPUB and Kindle. Book excerpt: "BioSonics was contracted by COE to conduct hydroacoustic studies at Bonneville Dam in 1997 in support of fish passage improvements. The work was organized into two Tasks according to the hydroacoustic methods. Task 1 has three objectives: 1.) Estimate the number of juvenile salmon passing into the sluicechute at the second powerhouse. 2.) Estimate the effects of sluicechute operation on the number submerged traveling screen (STS) guidance efficiency of juvenile salmon entering intake 11A. 3.) Evaluate different types of transducer mounts and mounting locations to estimate juvenile fish passage through the spillway. Task 2 has a single objective: determine the spatial and temporal distribution of juvenile salmon in the forebay of Bonneville Dam, by sluicechute operation, and by day and night. All three objectives of Task 1 were all addressed with fixed-location hydroacoustics. The Task 2 objective was addressed with mobile acoustic techniques." From executive summary.

Available in PDF, EPUB and Kindle. Book excerpt: The Portland District of the U.S. Army Corps of Engineers requested that scientists with the Pacific Northwest National Laboratory (PNNL) and the U.S. Army Engineer Research and Development Center (ERDC) conduct the hydroacoustic fish-passage studies described in this report. The ERDC also contracted with MEVATEC Corporation and Dyntel to provide staff ranging from scientists to technicians for the study. This study supports the Portland-District goal of maximizing fish passage efficiency (FPE) and obtaining 95% survival for juvenile salmon passing the Bonneville Project. This report presents results of two hydroacoustic studies of juvenile salmonids. One was a Project-wide study of fish-passage efficiency, and the other was more narrowly focused upon the approach, vertical distribution, and fish-guidance efficiency (FGE) of fish at Unit 15, where the Portland District extensively modified the gatewell and vertical barrier screen to improve gatewell flow and FGE. The goal of the larger of the two studies was to provide project-wide estimates of FPE, spill efficiency, and spill effectiveness for run-of-river fish passing the Bonneville Project during the 2001 out-migration. This type of study also provides estimates of the horizontal, vertical, and diel distributions of fish passage and FGE by turbine unit. These data will provide a baseline for evaluating the performance of future management efforts to improve juvenile fish passage. The goal of the second study was to assess the effect of gatewell and vertical-barrier-screen modifications on the FGE of Unit 15.

This book was released on 2002 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
