Book Description
During the mid-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 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.

Book Description
The St. Paul District, US Army Corps of Engineers and the US Geological Survey Upper Midwest Environmental Sciences Center examined the effects of locks and dams (Figure 1) on longitudinal fish movement in the Upper Mississippi River (UMR). The objective of this Long Term Resource Monitoring Program study was to estimate the opportunity for upriver passage through dams by adult migratory fishes. I identified UMR migratory fish species, estimated current velocities through gate openings on UMR dams, compiled information on migration behavior, and estimated the swimming for north performance of UMR migratory fishes. I used this information in combination with river discharge and dam operation records to estimate opportunity for upriver fish passage through the dams. Another objective was to examine the records of fish movements through UMR dams and to determine the head (difference between tailwater and pool water levels) when the fish passed through the dams. These results, reported in an earlier Project Status Report (PSR96 O4), summarized the findings of 126 UMR fish mark-recapture and telemetry studies.
