In the Missouri River main stem reservoirs in Montana, North Dakota, and South Dakota, hydrodynamic processes have decreased the lengths of shorelines and changed their configurations during the first 20 to 25 years of impoundment. Physical changes to the shore probably influenced fish abundance and species composition by changing the quality and quantityt of spawning and nursery habitat.

This report contains 367 annotations describing the effects of fluctuating reservoir water levels on fish. Citations on phytoplankton, zooplankton, and water quality that pertain to reservoir fisheries are also included. An index to facilitate location of references dealing with specific topic areas is included as an appendix. (Author).
