Abstract:

During the mid-1970s, an assessment of the potential for expansion of the nations hydroelectric generating capabilities was initiated by the passage of the Water Resources Development Act PL 94-587. Economic feasibility studies for small-scale hydropower development were performed for sites on the Upper Mississippi River UMR. The U.S. Fish and Wildlife Service has been asked to provide input into the final feasibility report and draft Environmental Impact Statements for hydropower development at Locks and Dams 5 and 8. This report as the following objective to compile, review, and analyze existing information on movements of adult fish through dams on the UMR from St. Anthony Falls to Lock and Dam 14. Secondary objectives include 1 identification of information gaps about adult fish movements and UMR fisheries in general that would prevent an accurate assessment of the impacts of small-scale hydropower development on UMR fisheries and 2 identification of impact assessment techniques, approaches, and means of obtaining the necessary data for an assessment of the impacts of small-scale hydropower development on ichthyoplankton and UMR fisheries.
