Mississippi River Locks and Dams 2–10 Miter Gates Replacement

Locks and Dams (LD) 2 through 10 have used the same miter gates since their construction in the 1930s. Over time, the gates have been damaged and distressed, which has led to serviceability and safety issues. This project will replace the gates and the anchorages system, increasing navigational longevity and operational readiness while decreasing repair costs and downtime due to maintenance or failure. Upper Mississippi Locks and Dams 2 through 10.

Mississippi River Locks and Dams 2–10 Tow Rail System

The tow rail system is integral to the operation of each of the Mississippi River Locks and Dams 2 through 10. It is attached to the top of the lock guidewall and helps guide tows through the lock chamber. Each system is comprised of an operating unit, rail and traveling kevel or “mule.” The Locks and Dams 2 through 10 tow rail systems have been deteriorating over the past several years, requiring rehabilitation of these systems.

Navigation: Routine Dam Gate Maintenance

Maintenance of the dam spillway gates are required to avoid degradation and eventual replacement. Benefit – cost analyses show it is economically favorable to maintain the gates rather than the replacement option. There are also reliability and safety concerns with allowing the gates to degrade to the point that they must be replaced. formed on site.

Pigs Eye Islands CAP 204 Beneficial Use of Dredge Material, St. Paul, Minnesota

The project will beneficially utilize dredge material to create islands that will provide a variety of habitat for fish and wildlife. Pigs Eye Lake is located in Ramsey County, just east of downtown St. Paul, Minnesota, in upper Pool 2 of the Mississippi River. Due to the lake’s close proximity to the Mississippi River, the lake water level is controlled by the level of the river. The lake is located in the Mississippi River Bottomlands Subwatershed.

Pool 2 Dredged Material Management Plan – Hennepin, Ramsey, Dakota and Washington Counties, Minnesota

The purpose of the Dredged Material Management Plan (DMMP) is to prepare a coordinated long-term plan for managing dredged material in Pool 2. This plan was initiated due to increases in dredging volumes throughout Pool 2. Furthermore, three temporary dredged material placement sites need to be excavated in Lower Pool 2.

Pool 2 Wing Dam Modification Project, Upper Mississippi River Pool 2, Minnesota

This project will notch a series of wing dams throughout Pool 2 in order to improve main channel border habitat for fishes. Wing dam notching will enable downstream scouring, which creates overwintering habitat. The project area is in the middle and lower half of Pool 2, Upper Mississippi River, downstream of St. Paul, Minnesota; spanning Dakota, Ramsey and Washington counties, Minnesota.

Small-Boat Harbor Dredging, St. Paul, Minnesota

The St. Paul Small-Boat Harbor is on the lower end of Harriet Island in St. Paul, Minnesota, at Upper Mississippi River mile 839.6 on the right descending bank. The length of the harbor is 2,375 feet; the width varies from 200 to 400 feet. The Corps of Engineers is authorized to maintain the harbor to a depth of 5.0 feet below low control pool elevation of 687.2 feet mean sea level (msl). The city of St. Paul is the non-federal sponsor for the project and is required to furnish a suitable placement site for the dredged material.

Tribal Partnership Program

The Tribal Partnership Program (TPP) provides authority for the U.S. Army Corps of Engineers to utilize TPP 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. To start the process, a tribe submits a study request to the U.S. Army Corps of Engineers. The Corps evaluates the request, and if viable, the Corps works with the tribe to determine a scope of work and enters into a feasibility cost sharing agreement (FCSA). Following the execution of the FCSA, the Corps seeks federal funding for the study.
