• Description:
  During the 1998 spring and summer juvenile salmonid migrations, we continued research to provide biological design criteria for the improvement of conventional juvenile salmonid wet separators, which are currently in use in fish passage facilities at hydroelectric dams on the Snake and Columbia Rivers. In addition, we conducted evaluations to develop the high-velocity flume (HVF) wet separator and tested a preliminary adult and debris separator designed to remove large fish and debris before they reach the juvenile wet separator. Both the conventional and HVF separator units were used to trap river-run smolts from Gatewell 6B at McNary Dam.
