    Beneficial Use of Dredged Material: Section 1122, Upper Pool 4 – Lake Pepin, Bay City, Wisconsin

    This project utilizes dredged material generated from the navigation channel to protect and restore backwater habitat; this is a win-win project for the U.S. Army Corps of Engineers, our partner agencies, and the environment. The Wisconsin Department of Natural Resources is the nonfederal sponsor.

  • Disposition Study: Lower St. Anthony Falls Lock and Dam and Lock and Dam 1, Upper Mississippi River

    This work will determine whether continued operation and ownership of Lower St. Anthony Falls Lock and Dam and Lock and Dam 1 are in the federal interest, and if not, consider alternatives for disposal of the property.

  • Mississippi River Locks and Dams 2–10: Miter Gate Replacements

    Locks and Dams 2 through 10 have used the same miter gates since their construction in the 1930s. Over time, the gates have been damaged and distressed, leading to serviceability and safety issues. This project will replace the gates and upgrade the anchorage systems, increasing navigational longevity and operational readiness while decreasing repair costs and downtime due to maintenance or failure.

  • Navigation: Upper Mississippi River 9-Foot Channel Navigation Project Maintenance

    The U.S. Army Corps of Engineers is responsible for maintaining a 9-foot navigation channel as an important component of the inland navigation system.

  • Upper Mississippi River – Navigation and Ecosystem Sustainability Program: Johnson Island Project, Wisconsin

    The Navigation and Ecosystem Sustainability Program is a long-term program of ecosystem restoration and navigation improvements for the Upper Mississippi River System. Johnson Island is located near Trempealeau, Wisconsin, in Pool 6 of the Mississippi River. Island erosion, island dissection, and sedimentation have greatly reduced the quality and quantity of terrestrial and aquatic habitat in the project area. Project objectives are directed at improving conditions for fish, aquatic and terrestrial wildlife, maintaining emergent vegetation, maintaining submersed vegetation and island stabilization and nourishment to restore connectivity, and promotion of floodplain forest regeneration.

  • Upper Mississippi River – Navigation and Ecosystem Sustainability Program: Sny Magill Project, Iowa

    This Navigation and Ecosystem Sustainability Program study is a partnership with the National Park Service, U.S. Fish and Wildlife Service, Iowa Department of Natural Resources, Wisconsin Department of Natural Resources, and U.S. Army Corps of Engineers. The study will consider alternatives including riverbank stabilization and protection, floodplain restoration, closure or partial closure structures, and in-channel diversion structures.

  • Upper Mississippi River – Navigation and Ecosystem Sustainability Program: Systemic Mitigation Island 4 Project, Wisconsin

    The primary purpose of this project is to address general degradation of habitat quality due to sediment deposition, wind-driven wave action, declining bathymetric diversity, and a decline in aquatic vegetation. Concerns over habitat deficiencies in Upper Pool 4 include reduced habitat diversity and quality, lack of aquatic vegetation and invertebrates, and reduced abundance of fish and wildlife.

  • Upper Mississippi River – Navigation and Ecosystem Sustainability Program: Wacouta Bay Project, Wisconsin

    Concerns over habitat deficiencies in Wacouta Bay, most resulting from sedimentation and turbidity, include reduced aquatic and terrestrial habitat diversity and quality, lack of aquatic vegetation, lack of protected wetlands, and reduced abundance of fish and wildlife. The Wacouta Bay project is a Navigation and Ecosystem Sustainability Program study that will consider alternatives including island building and enhancement, forest enhancement and creation, backwater restoration and dredging, island and shoreline protection, and use of dredged material.
  • Lock and Dam 6, near Tremplealeau, Wis.

    Upper Mississippi River 9-Foot Channel Navigation Project: Locks and Dams, Minnesota/Wisconsin/Iowa

    The U.S. Army Corps of Engineers St. Paul District is responsible for maintaining 244 miles of the Upper Mississippi River 9-foot channel navigation system. The navigation project within the St. Paul District includes 13 locks and dams that are operated and maintained by the U.S. Army Corps of Engineers.

  • Upper Mississippi River Restoration Program: Big Lake, Pool 4, Wisconsin

    The sedimentation of backwater areas of the Upper Mississippi River is an ongoing issue. The project area is greatly influenced by the input of sand from the Chippewa River, entering Pool 4 at approximately river mile 764. Other potential sources of sand are the historic channel maintenance dredging side-cast islands and the four active temporary placement sites within the study area. Big Lake has lost much of its island complex and bottomland forest to wind and wave erosion. The barrier islands between the lake and Catfish Slough have been degraded and/or eliminated over the past several years.
