First Powerhouse, Bonneville Dam, Columbia River, Oregon, Report 2, Tracking Velocities: Hydraulic Model Investigation

Abstract

Surface collectors are being studied as a possible solution for bypassing juvenile salmon around the turbines. Juvenile fish tracking studies were conducted in 1998 in the forebay of the powerhouse in the vicinity of the surface collector. A 1:40-scale model of the powerhouse was utilized to obtain three-dimensional velocity information in the same vicinity of the surface collector. The velocity information was provided to Portland District to overlay with the fish tracking data to determine if the juvenile salmon were following the flow lines into the surface collector.
