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.

This book was released on 2015 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the Abstract:Columbia River hydropower is an economic mainstay of the Pacific Northwest. However, it is well known that the construction of hydropower dams has added anthropogenic pressure to Columbia River salmon populations. Juvenile salmon that pass through powerhouse turbines at large hydropower dams display higher mortality rates than salmon passing through alternative routes; thus at Priest Rapids Dam, a top-spill fish bypass was constructed as a safer alternate downstream passage. To investigate the efficacy of this new passage structure, an acoustic telemetry study was conducted in the spring of 2014 to determine the ability of the bypass to collect and safely pass juvenile steelhead and Chinook salmon. The bypass collected 47% of the monitored steelhead and 38% of the monitored yearling Chinook salmon. Analysis of route choice identified forebay temperature, powerhouse discharge, spillway discharge and forebay approach patterns as significant drivers of passage selection. Immediately following dam passage, steelhead and Chinook salmon that used the bypass had higher survival and migrated faster compared to powerhouse route fish. The Priest Rapids Fish Bypass served its intended purpose by reducing the anthropogenic footprint of this hydroelectric facility on migrating juvenile salmon, which will aid the potential recovery of Columbia River salmon.

Available in PDF, EPUB and Kindle. Book excerpt: This study compares hydroacoustics-based estimates of fish passage and passage metrics for two spill treatments (30- and 64-percent spills) and concomitant powerhouse operations at The Dalles Dam during the 1000 spring and summer juvenile salmon passage seasons. Data were analyzed for significant differences (Wilcoxen Signed-Rank Tests, alpha = 0.05) in daytime nighttime, and total daily fish passage and passage metrics over six 3-day treatment blocks in spring and summer. Horizontal distributions of fish passage at spillway and powerhouse and vertical distributions of fish at sluiceway and powerhouse are presented by treatment and time of day for each season. Project fish-passage efficiency (FPE) and spill efficiency were significantly higher with the higher spill and lower powerhouse generation treatment at night but not during days in both seasons. Sluiceway efficiency was higher with the lower spill and higher generation treatment at night in spring and both night and day in summer. Spill passage was not significantly different during day or night in spring but was higher with the higher spill treatment during summer nights (but not days). Sluiceway passage was higher during spring days and nights during the 30-percent spill than during the 64-percent spill but not different during days or nights in summer. Turbine passage was higher with the lower spill treatment at night in both seasons. Results should be considered in light of the confounding effects of higher spill vs. lower generation and the converse, which was inherent in the experimental design. Statistical methods, a detailed evaluation of the 'acoustic screen model', and an evaluation of two methods for estimating passage at unsampled spill bays are presented in the appendixes.

Book excerpt: Odeh (Conte Anadromous Fish Research Center) presents 13 contributions which explore the technical possibilities of constructing effective fish bypass systems for hydroelectric dams, especially those that are due for relicensing in the context of new regulations. The articles consist of case studies in the effectiveness of such techniques as surface bypass systems, modular inclined screens, hydroacoustic evaluation of fish entrainment patterns, surface collection, surface spill gates, and radio-tagging and radar tracking behavior evaluation strategies.
