Effects of Fluctuating Reservoir Water Levels on Fisheries, Wildlife, and Vegetation; Summary of a Workshop, 24-26 February 1981

摘要

For many years, large reservoirs have been constructed throughout th;e United States to provide flood control, power sources, and recreation areas. Design and operational characteristics of these reservoirs determine the types of habitat available to fish and wildlife species. Periodic fluctuations in water level on reservoirs are of particular concern to natural resource managers. The seasonal fluctuations that occur on many lakes and flood-control reservoirs and the daily fluctuations that are necessary on some hydroelectric projects often result in elimination of shoreline vegetation, which causes erosion, diminished water quality, and habitat loss or degradation. This report presents abstracts of papers presented at a workshop organized to identify the problems resource managers face and to present research results that might be applied to alleviate or moderate the adverse effects of reservoir fluctuation. Sessions were organized under the general topics of vegetation, wildlife, and fisheries. Discussions of the results of the workshop sessions and possible means of resolving conflicts between the requirements of the reservoir biota and the principal operational goals of the reservoir projects are also presented. Addresses of the principal authors are provided to allow readers to seek further information regarding particular studies. (Author)
