【 摘 要 】

This report describes a study conducted by Pacific Northwest National Laboratory to identify populations of migrating juvenile salmonids with a potential to be impacted by repeated exposure to turbine passage conditions. This study is part of a research program supported by the U.S. Department of Energy Wind/Hydropower Program. The program's goal is to increase hydropower generation and capacity while enhancing environmental performance. Our study objective is to determine whether the incremental effects of turbine passage during downstream migration impact populations of salmonids. When such a potential is found to exist, a secondary objective is to determine what level of effect of passing multiple turbines is required to decrease the number of successful migrants by 10%. This information will help identify whether future laboratory or field studies are feasible and design those studies to address conditions that present the greatest potential to improve dam survival and thus benefit fish and power generation.
