During the nid-1970's, an assessment of the potential for expansion of the nation's 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 was performed for sites on the Upper Mississippi (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 Dam 5 and 8. The following report has these objectives: first, to compile, review, and analyze existing information movements of ichthyoplankton through dams on the UMR from above St. Anthony Falls to Lock and Dam 14. Secondly, to identify information gaps about ichthyoplankton drift and UMR fisheries in general that would prevent accurate assessment of the impacts of small-scale hydropower development on UMR fisheries; and also to identify 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.
