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.

Dredged Material Management Plan: Pool 10, Wisconsin/Iowa

The purpose of the Pool 10 Dredged Material Management Plan is to prepare a coordinated, long-term plan for managing dredged material in Pool 10. This plan was initiated due to needs for dredged material management at upland placement sites, especially in the downstream reach of the pool.

Dredged Material Management Plan: Pool 9, Minnesota/Wisconsin/Iowa

The U.S. Army Corps of Engineers operates and maintains the Upper Mississippi River 9-Foot Channel Navigation Project, and one method used to maintain the 9-foot channel is dredging river soils or “material.” The purpose of the Pool 9 Dredged Material Management Plan is to prepare a coordinated long-term plan for managing dredged material in Pool 9. This plan was initiated due to needs for dredged material management at upland placement sites, especially in the upstream reach of the pool.

Eau Galle Lake, Wisconsin

Authorized purposes of the Eau Galle Lake Project include flood control, recreation, and enhancement of fish and wildlife. Eau Galle Lake is located on the Eau Galle River in Wisconsin.

Flood Risk Management: Section 205, Trempealeau River, Arcadia, Wisconsin

The purpose of this project is to reduce the risk of damages due to flooding in the city of Arcadia, Wisconsin. The city is located on the Trempealeau River, with Turton Creek and Meyers Valley Creek flowing into the Trempealeau River on the east and west sides of the city, respectively.

Hydropower: Federal Energy Regulatory Commission Licensing

Granting licensing of a privately-owned hydropower project on federal property. The project is proposed to be located at Upper St. Anthony Falls lock and dam, in Minneapolis, Minnesota.

Mississippi River Locks and Dams 2–10: Embankment Rehabilitation Adjacent to Structures

This embankment rehabilitation project addresses restoring embankments to meet current design standards. Overtopping protection adjacent to concrete structures is the priority for design and construction efforts; no increase in the height of the embankments is planned.

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.

Mississippi River Locks and Dams 2–10: Tow Rail System

The tow rail system is integral to the operation of Mississippi River Locks and Dams 2 through 10. At each lock, a tow rail system is attached to the top of the lock guidewall to help guide tows through the lock chamber. The tow rail systems of Locks and Dams 2 through 10 have been deteriorating over the past several years, requiring rehabilitation of these systems.

Mississippi River Recreation and Environmental Stewardship

Although navigation was the initial purpose of the Upper Mississippi River 9-Foot Channel Navigation Project, Congress has since authorized the development of recreational facilities, protection of forest resources, and required the consideration of fish and wildlife conservation.

Navigation and Ecosystem Sustainability Program

The Navigation and Ecosystem Sustainability Program (NESP) seeks to provide a safe, reliable, cost-effective and environment-sustainable waterborne navigation system by implementing switchboats at five locks and constructing mooring cells and seven new 1,200-foot locks. NESP will restore the aquatic and terrestrial habitat to a more natural condition on more than 100,000 acres throughout the system through a wide variety of ecosystem projects.

Navigation: Fountain City Service Base Sustainment and Modernization, Wisconsin

The Fountain City Service Base Sustainment and Modernization Project is a two-phase project to improve function and safety throughout the service base. The two objectives of the project are to replace the deteriorated mooring dolphins on the west side of the Fountain City harbor channel and modernize the service base.

Navigation: Routine Dam Gate Maintenance

Maintenance of dam spillway gates are required to avoid degradation and eventual replacement. Cost analyses show it is economically favorable to maintain these gates rather than replace them. There are also reliability and safety concerns with allowing the gates to degrade to the point that they must be replaced.

Tribal Partnership Program

The Tribal Partnership Program provides authority for the U.S. Army Corps of Engineers to perform water-related planning activities and activities related to the study, design and construction of water resources development projects located primarily on tribal lands that substantially benefit federally recognized tribes.

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 9-Foot Channel Navigation Project: Maintenance, Minnesota/Wisconsin/Iowa

The St. Paul District is responsible for maintaining 244 miles of the Upper Mississippi River 9-Foot Channel Navigation Project for inland navigation.

Upper Mississippi River Restoration Program: Lower Pool 10 Island Habitat Restoration, Iowa

Many natural islands bordering the U.S. Army Corps of Engineers-maintained Mississippi River navigation channel and extending into the backwater have eroded and are disappearing. Erosion from wave action and main channel flows reduces the wetland, resulting in the loss of aquatic vegetation and shallow protected habitats necessary for fish and wildlife to survive. The purpose of this project is to reestablish lost habitat and ecosystem health.

Upper Mississippi River Restoration Program: McGregor Lake Habitat Restoration, Wisconsin

The purpose of this project is to support diverse and abundant native fish, wildlife and plants while sustaining a high level of environmental health and promoting recreation opportunities.
