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.

Location

McGregor Lake is a 200-acre backwater lake in Pool 10 of the Mississippi River. The McGregor Lake project is located on the Wisconsin side of the Upper Mississippi River in the middle of Pool 10, near Prairie du Chien, Wisconsin. The site lies within the Upper Mississippi River National Wildlife and Fish Refuge.

Description

McGregor Lake and the surrounding area have undergone degradation in the recent past. Emergent and submergent vegetation are lacking, and shorelines are eroding, which impacts floodplain forest as well as the federally protected Higgins eye pearly mussel.

The McGregor Lake project aims to improve lake habitat for backwater fish species, increase emergent vegetation growth, increase submergent vegetation growth, increase age and species diversity of self-sustaining floodplain forest, and protect aquatic and terrestrial habitat by reducing erosion. Project features include backwater habitat deepening, floodplain forest creation, shoreline protection, and wetland creation. The McGregor Lake project has used over half a million cubic yards of clean sand from the navigation channel.

Status

The construction contract for Stage 1 was awarded in September 2020 and completed in 2023. The contract for Stage 2 was awarded in September 2022 and will be completed in 2025.

Authority

Congress originally authorized the Upper Mississippi River Restoration Program in Section 1103 of the Water Resources Development Act (WRDA) of 1986, Public Law 99-662 (codified as amended at 33 U.S. Code 652). Section 8345 of WRDA 2022, Public Law 117-263, increased the authorized program funding to a combined $90 million annually.

The project was planned and designed as part of a cooperative effort of the U.S. Army Corps of Engineers, the U.S. Fish and Wildlife Service, the Iowa and Wisconsin Departments of Natural Resources, and local interests.

Funding

Project design and construction will be 100% federally funded because the project is located on lands managed as a national wildlife refuge. Operations and maintenance will be 100% federally funded and a responsibility of the U.S. Fish and Wildlife Service.

Federal funds allocated to date $23,566,854
Estimated project construction costs $24,317,000
