Description:

In 1998, we conducted research at Bonneville Dam First Powerhouse to determine levels of improvement in fish guidance efficiency (FGE), 24-hour orifice passage efficiency (OPE), and levels of descaling and injury using three extended-length submersible bar screens (ESBSs) installed in Turbine Unit 8. To further improve FGE by increasing flows into the gatewell, operating gates were raised in the A and C slot ofTurbine Unit 8, and the gate was removed in the B slot to accommodate a fyke-net frame for FGE testing.
