Continuing Authorities Program: Beneficial Use of Dredged Material, Section 204, Upper Pool 4 – Lake Pepin

Lake Pepin extends about 22 miles in length from the delta of the Chippewa River to approximately River Mile 787 which is about 3 miles downstream of Red Wing, Minnesota. Upper Lake Pepin consists of channel border islands and backwater lakes grading into an expansive, shallow open water area with little physical structure. Sedimentation and sediment resuspension have caused a loss in water depth diversity of the backwater lakes and isolated wetlands above Lake Pepin as well as a loss in aquatic vegetation.
