All Minnesota flood control sites include flood risk management, recreation and environmental stewardship business line functions. Each has public use facilities for shore fishing, picnicking, bird watching and other activities. The land is actively managed for habitat enhancement.
Lake Traverse is on the Minnesota–South Dakota border between Browns Valley, Minnesota, and Wahpeton, North Dakota/Breckenridge, Minnesota. It consists of two dams, two reservoirs and the Browns Valley Dike.
Orwell Lake on the Otter Tail River is approximately six miles southwest of Fergus Falls, Minnesota. It consists of an earthen embankment, outlying dikes and a gated service spillway.
Highway 75 Dam is on the upper Minnesota River near Odessa, Minnesota. It impounds the Big Stone National Wildlife Refuge.
Lac qui Parle is on the Minnesota River near Montevideo, Minnesota. It consists of three dams, a diversion channel and several embankments and levees.
Red Lake Dam is located at the outlet of Lower Red Lake in the northeastern part of Clearwater County, Minnesota. It consists of an earthen embankment, a concrete weir with three lift gates and two stop log bays.
Flood risk management, recreation and environmental stewardship activities are completed by U.S. Army Corps of Engineers staff at Lake Traverse, Orwell Lake and Lac qui Parle. These sites also support readiness (emergency) response activities in the Minnesota and Red River basins. Water control activities have a direct impact on flood response in the downstream communities. Low flows are managed for fish and wildlife purposes and for water supply for communities on the Red River of the North. Red Lake Project activities are completed by Corps staff at Grand Rapids, Minnesota. Since their construction, the reservoirs have prevented combined flood damages of over $5,275,000,000.
A $5,700,000 construction contract, awarded in 2020 for dam modification and equipment refurbishment of Lac Qui Parle Dam, is scheduled to finish in late 2022. An architectural engineering contract was awarded in fiscal year 2022 to develop plans and specifications for repair of the emergency spillway at the Lac Qui Parle Dam, which was damaged from high flows in 2019. Infrastructure Investment and Jobs Act (IIJA) funds will be used to award a construction contract in late 2022.
