This book was released on 2009 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Previous studies have identified Lower Granite Dam fish ladder as having as high temperature differentials during summer months. In 2008, we monitored water temperatures within the fish ladder and the passage of radio-tagged adult salmonids at Lower Granite Dam. Water temperatures in the fish ladder were cooler than in previous study years, with only five percent or less of all radio-tagged fish passing the dam when water temperatures differences between upper and lower segments of the fishway exceeded 1 °C. The warmest average monthly temperatures occurred in August and differences in temperature between the top and bottom of ladder the ladder exceeding 1 °C occurred on one day in July and one day in October. A significantly higher percentage of spring-summer Chinook salmon (O. tshawytscha) exited the fish ladder to the tailrace when temperatures exceeded 18 °C than when water ladder temperatures were less than 18 °C. We did not find differences in the percent of steelhead (O. mykiss) and fall Chinook salmon that exited the ladder when temperatures were greater than or less than 18 °C. Median dam and transition pool passage times were higher for all runs of radio-tagged fish when water ladder temperatures exceeded 18 °C. Most tagged fish that exited the dam to the tailrace did so after reaching the transition pool area of the ladder regardless of temperature. We found a higher percentage of fish overnighted when water temperatures were greater than 18 °C. Since 2008 was a relatively cool year, future studies may be needed to more effectively evaluate the relationship between fish passage and temperature gradients within the fish ladder at Lower Granite Dam."--Abstract.

This book was released on 2008 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Evaluation of fishway entrance use and passage through fishways by spring–summer Chinook salmon Oncorhynchus tshawytscha, steelhead O. mykiss, and sockeye salmon O. nerka at Bonneville Dam were objectives of the adult salmon and steelhead passage project in 1997, 1998, 2000, 2001, and 2002. Critical parameters studied were times for a fish to first approach and first enter a fishway, total time to pass over the dam, which openings were approached, where fish entered and exited fishways, and fish passage through transition pools and over the dam. We report here on study results from five years of spring–summer Chinook salmon data, four years of steelhead data, and one year of sockeye salmon data."--From executive summary (page v).
