摘要

The overall goal of the Red Bluff Research Pumping Plant (RPP) biologicalevaluation program was to determine whether Archimedes lifts and internal helical pumps could be used to deliver water to the Tehama-Colusa canal without harming fisheries resources in the Sacramento River, with emphasis on chinook salmon. From February 1997 through May 2000, 133 trials were conducted to evaluate species, numbers, and characteristics of fish entrained from the river into the RPP. Trials lasted 24 hours and were segmented into diurnal and nocturnal periods. After passing through a lift or pump, fish were captured in downstream holding tanks, identified, measured (length), and assessed for mortality and injury. The specific objectives addressed in this study were: (1) determine diel and seasonal patterns of entrainment, (2) compare mortality and injury to fish passed through Archimedes lifts and the internal helical pump, (3) estimate the number of chinook salmon entrained annually, and (4) estimate the fraction of juvenile chinook salmon passing Red Bluff Diversion Dam that were entrained into the RPP.
