Download or read book Evaluation of Fishway Modifications to Improve Passage of Adult Chinook Salmon and Steelhead Through the Transition Pool at Lower Granite Dam 2008 written by T. S. Clabough and published by . This book was released on 2009 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Previous studies of Pacific salmon migration behaviors at Snake River dams indicated slow passage at transition pools in adult fishways. In 2001 and 2002, we conducted an experiment to evaluate if modified weirs affected adult salmon and steelhead passage times and route selection through the Lower Granite Dam transition pool. Attraction flows through weir orifices were experimentally manipulated using removable aluminum panels. Results from the 2001-2002 studies indicated a greater percentage of radiotagged spring–summer Chinook salmon passed straight through the transition pool and median transition pool passage times were significantly lower when the panels were deployed. Based on these results, the U.S. Army Corps of Engineers modified the fish ladder at Lower Granite Dam in 2006 prior to the migration season. Modifications included narrowing the transition pool and increasing the weir crest height of the lowest eleven weirs. To evaluate the effectiveness of the modifications, we radio-tagged and monitored adult spring-summer and fall Chinook salmon and steelhead as they passed Little Goose and Lower Granite dams and compared their performance to that measured during previous years without modifications in place. Transition pool passage times at Lower Granite Dam for spring-summer Chinook salmon were significantly faster in 2006 than in 2003 and 2004 (non-modified years). Spring-summer Chinook salmon passage times were also faster in 2008, though the results were not statistically different (P > 0.05) than in 2003 and 2004. The other runs exhibited similar, though not statistically different responses. The frequencies of downstream exits from the Lower Granite transition pool to the tailrace for spring Chinook salmon in 2006 and 2008 were lower than in 2003 and 2004. We also compared the difference in passage times by individual fish at Little Goose and Lower Granite dams in an effort to statistically control for interannual variation in river environment. Comparisons of interannual differences in passage times at the two dams indicated that passage times decreased for individual fish at Lower Granite Dam compared to Little Goose dam in modified years compared to the non-modified years. Passage times through the Lower Granite transition pool were also faster in 2006 and 2008 than in 2003 and 2004. However, the transition pool passage times were not as low as those achieved during the experimental weir modifications in 2001 and 2002 and passage behavior only improved for spring-summer Chinook salmon during 2008 with the permanent modification. This difference may have been caused by differences in river conditions among years, differences in fishway hydraulics between the experimental and permanent modifications, or both."--Abstract (page iii).

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.
