Description:

The Ice Harbor Dam juvenile salmonid sampling facility and bypass system was completed and ready for operation for the 1996 spring outmigration. This bypass system is similar to those at Lower Monumental, Little Goose, and McNary Dams, but does not include a raceway area to hold migrants for transportation purposes. Primary operation is to bypass fish around the dam and return them to the river just downstream from the tailrace area, but samples can be taken on an "as needed" basis. Prior to the facility being operated in the bypass mode, we evaluated the system by visually inspecting the entire fish passage system. We examined both juvenile and adult migrants for descaling and gross external injuries, and analyzed blood samples from juveniles for evidence of stress build-up.
