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.

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: 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.

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: 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.

Upper Mississippi River - Illinois Waterway System Navigation and Ecosystem Sustainability Program (NESP)

Navigation and Ecosystem Sustainability Program (NESP) is a long-term program of ecosystem restoration and navigation improvements for the Upper Mississippi River System (UMRS). NESP will improve system capacity and reduce commercial traffic delays through construction of seven new 1,200-foot locks, mooring cells, and switchboat implementation.

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.
