The 9-foot navigation channel on the Upper Mississippi River was authorized by the Rivers and Harbors Act of July 3, 1930, and other legislation. The great River Environmental Action Team GREAT I study was organized in 1973 to identify and assess the problems associated with multipurpose use of the Mississippi River. One of the main products of the GREAT I study was a 40-year channel maintenance plan for the river. The project discussed in this supplement would implement the general channel maintenance plan for lower pool 5 on the Upper Mississippi River, including the rehabilitation of the 4,000-acre backwater lake, Weaver Bottoms. The primary objectives of the project are to develop a 40-year channel maintenance plan for lower pool 5, reduce maintenance dredging requirements in lower pool 5, and restore the habitat quality to the Weaver Bottoms area, by modifying side channels and constructing islands with maintenance-dredged material.
