Description:In 2007, we evaluated behavior, passage distribution, and survival of yearling Chinook salmon and steelhead at Ice Harbor Dam to determine effects of the recently installed removable spillway weir (RSW) during two different spill operations. A portion of study fish were those collected and surgically tagged with both a radio transmitter and PIT tag for similar evaluations at Lower Monumental Dam. Treatment groups for the Ice Harbor evaluation were the 663 yearling Chinook salmon and 665 juvenile steelhead released 5 km above Lower Monumental Dam and the additional 635 yearling Chinook and 646 juvenile steelhead released into the tailrace of Lower Monumental Dam.
