Abstract: | The construction of a ~145 meter spill wall at The Dalles Dam 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 the new spill wall, spill volume, and a spill pattern, which directs most water though the northern-most spillbays, may have affected behaviors and passage times of radio-tagged adult spring–summer Chinook salmon in 2010. |
