The U.S. Army Corps of Engineer’s (COE’s) Turbine Survival Program (TSP) is part of the COE’s multi-faceted Columbia River Fish Mitigation (CRFM) program. The TSP was developed to quantitatively evaluate juvenile fish passage through turbines with an emphasis on identifying turbine structures and operations responsible for injury to fish. The first phase (Phase I) of this study includes four main objectives: 1.) Evaluate and recommend operational criteria to improve the survival of fish passing through the Kaplan turbine units. 2.) Identify the biological design criteria for the design of new modifications to the existing turbines. 3.) Investigate modifications to the existing designs that have the potential to increase survival of fish passing through the Kaplan turbine units. 4.) Recommend a course of action for turbine rehabilitation or replacement that incorporates improvements for fish passage survival. As the COE makes decisions to replace or rehabilitate aging turbine units it is important that these objectives be met so knowledgeable decisions can be made to enhance fish passage survival while maintaining cost effectiveness. Rehabilitation of a number of Corps projects is already underway. New Kaplan turbines are being installed into the Bonneville First Powerhouse (B1) and new turbine designs are being developed for the McNary Project. Unit 2 of Ice Harbor will be replaced in 2005 and a rehabilitation plan is being considered for The Dalles Project. Other Corps Projects on the Lower Snake and Columbia rivers have been in service for more than 30 years and will soon require rehabilitation. It is critical to long-term operations that the rehabilitation process considers and includes, where feasible, modifications or new designs that improve fish condition and survival as they pass-through the turbines. This report documents the major work accomplished and results obtained during Phase I of the TSP and represents the completion of Phase I activities.
