None supplied. From executive summary: The Turbine Survival Program (TSP) was developed to investigate means to improve the survival of juvenile salmon as they pass through Kaplan turbines located at Columbia and Snake River dams. The TSP is one part of the U.S. Army Corps of Engineers (COE) multi-faceted Columbia River Fish Mitigation Program. The purpose of this annual report is to document the studies and findings that were conducted under the TSP in FY97. Funding and regional support for the TSP was provided in April 1997. Thus, work was initiated on the program about halfway through FY97. Technical staff from the COE Portland and Walla Walla Districts, Waterways Experiment Station (WES) and Hydroelectric Design Center (HDC) are team members on the TSP. The objectives of the TSP are: (1) Develop modifications to the way existing Kaplan turbines are currently operated to improve fish passage survivability and condition as they pass through the existing turbines, (2) Identify biological design criteria that will provide the basis for the development of improved turbine designs, (3) Investigate improved fish passage turbine designs or modifications to existing designs that could be implemented to assist the recovery of Columbia and Snake River salmon stocks, and (4) Provide information on turbine passage survival, which can be factored into the 1999 system configuration decisions. The TSP is organized along three functional elements and disciplines that must be investigated and integrated to achieve the objectives of the program. These are biological, engineering, and hydraulic model investigations.
