Marsh Lake Ecosystem Restoration Project

The Minnesota Department of Natural Resources, as the Responsible Governmental Unit for environmental review of the Marsh Lake Ecosystem Restoration Project in Big Stone, Lac qui Parle, and Swift Counties, Minnesota, has issued the attached Record of Decision regarding the Need for an Environmental Impact Statement for the project. The project's Environmental Assessment Worksheet (EAW) notice was published in the July 11, 2016 issue of the EQB Monitor (Vol. 40, No. 28).

The DNR has concluded that an Environmental Impact Statement (EIS) is not required because the project does not have the potential for significant environmental effects. The justification for this determination is contained in the Record of Decision. The Record of Decision also contains the Department's responses to all substantive written comments received on the Environmental Assessment Worksheet during the 30-day review and comment period.

Issuing this Record of Decision concludes the State environmental review process for this project according to the Minnesota Environmental Quality Board rules, Minnesota Rules, part 4410.1000 to 4410.1700. This project can proceed to permitting and approvals.

For additional information, or copies of the Record of Decision, please call 651-259-5072.


The proposed project

The Minnesota Department of Natural Resources, Wildlife Section proposes to restore the aquatic and riparian ecosystems within the Marsh Lake project area, which is along the Minnesota River and within the Lac qui Parle Wildlife Management Area (WMA) boundary. Marsh Lake is a 5,000 acre shallow reservoir along the Minnesota River in Big Stone, Chippewa, Lac qui Parle, and Swift Counties. The project includes construction of a rock-ramp fishway, a water control/drawdown structure, a new dam access road and embankment features, restoration of the Pomme de Terre River to its historic channel, additional parking areas, and use of a borrow location for the earthen materials needed for project construction. Modifications to the existing dam structure would provide more natural variability in water levels and also provide habitat connectivity through the rock-ramp fishway.

The Marsh Lake Ecosystem Restoration Project is a cooperative project between the U.S. Army Corps of Engineers, the Minnesota Department of Natural Resources, and the Upper Minnesota River Watershed District.
