This project proposes to utilize dredged material generated from navigation channel dredging to protect and restore backwater habitat; this is a win-win-win project for the U.S. Army Corps of Engineers, our partner agencies and the environment. The Wisconsin Department of Natural Resources (WDNR) is the non-federal sponsor.
The project is the routine maintenance, including painting and repair of the dam gates. Phase 1 consisted of report development, including alternatives and life cycle costs. Phase 2 of the project analyzed the alternatives, and decided upon an Indefinite Delivery – Indefinite Quantity (IDIQ) acquisition strategy with maintenance performed on site.
Determine whether or not continued operation and ownership of Upper St. Anthony Falls Lock and Dam (USAF) is in the federal interest, and if not, provide supporting information for deauthorization of the project purposes and disposal of the property. USAF is located on the Mississippi River in Minneapolis, Minnesota.
The U.S. Army Corps of Engineers is responsible for maintaining a 9-foot navigation channel as an important component to the inland navigation system. The St. Paul District (MVP) is responsible for maintaining 244 miles of the Upper Mississippi River 9-Foot Channel Navigation Project from the head of navigation at Minneapolis, Minnesota, to Guttenberg, Iowa. The navigation project also includes the lower navigable portions of the Minnesota, St. Croix, and Black Rivers.
The hydrology in the area has changed significantly, driven in part by change in land use and climate. The proposed project aims to improve habitat for aquatic vegetation and migratory waterfowl by providing water level management capabilities that target management goals of the refuge. This study area is located within the Minnesota Valley National Wildlife Refuge in an urban floodplain area near the cities of Shakopee and Savage, Minnesota. The lake and marsh areas are south of the Minnesota River (river miles 15‒21) and include Blue Lake, Fisher Lake, Rice Lake and the adjacent Continental Grain Marsh.
