Description:

This study was initiated to evaluate the condition of juvenile salmonids during passage through the fish bypass and collection system at McNary Dam, with an emphasis on identifying guidance structures and turbine operations that may cause fish injuries. Although earlier studies at McNary Dam indicated that juvenile salmonid survival may not differ over a range of turbine discharges, the more turbulent conditions associated with higher discharges, together with debris accumulation, may require structural modifications to protect fish in the gatewells. A rotating vertical barrier screen was installed in gatewell 4A to address this issue.
