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.

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.

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 - 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.
