- Abstract:
- At The Dalles Dam, construction of a ~145-m spill wall was completed in April 2010 and was designed to improve the survival of spillway-passed juvenile salmonids by directing them toward deep water with fewer predators. We evaluated how behavior and passage time of radio-tagged adult and jack spring-summer Chinook salmon Oncorhynchus tshawytscha and sockeye salmon O. nerka in 2013 were affected by three factors: 1) a new spill wall, 2) changing spill volumes, and 3) a spill pattern that directs most water though the northern-most spillbays. We focused analyses on fish size and use of the north fishway.
