Pagination or Media Count:
As part of its long-term statutory mission the U.S. Corps of Engineers maintains a nine-foot navigation channel in the Mississippi River by a system of locks and dams supplemented by maintenance dredging. Largely sand, the dredged material has been placed in the flowages each year to create dredge spoil sites, which appear as islands or sand bars. This report on recreational use of these artificial islands or sites is one phase of an overall study of the Mississippi River underway by the Great River Environmental Action Team GREAT. Major agencies participating in this interdisciplinary study group are the U. S. Army Corps of Engineers, U.S. Fish and Wildlife Service, USDA Soil Conservation Service, U.S. Geological Survey, as well as state conservation commissions, state historical societies, state departments of natural resources, and state departments of transportation. A major concern of the GREAT study is to develop a plan to resolve any problems environmental or otherwise of the dredge materials disposal. GREAT work groups are exploring uses and places where the dredged materials can be an asset, means to minimize sedimentation, and acceptance of disposal sites for recreational use.
