Description:

Juvenile salmonid bypass facilities at hydroelectric dams on the Snake and Columbia Rivers are used to route fish past the dam through a non-turbine route and to collect juveniles for subsequent transportation and release below the dams. A major component of these systems is the primary dewatering screen, which removes excess water from the fish bypass channel and diverts juvenile migrants to holding and collection facilities. A combination of vertical and floor dewatering screens is used as the primary dewatering system at several dams on the Snake and Columbia Rivers.
