Description:

Submersible traveling screens (STSs) are installed in all turbine units at Bonneville Dam First Powerhouse to guide juvenile salmonid migrants into a juvenile fish bypass system. In tests conducted from 1989 to 1992, fish guidance efficiency (FGE) ofthese screens ranged from approximately 40% for yearling chinook salmon to 60% for coho salmon and steelhead during the spring migrations. During the same testing period, FGE for sockeye salmon was approximately 25%. During the summer migrations, FGE for subyearling chinook salmon was approximately 40% in June, then decreased to less than 10% by the second week in July.
