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.
The Flood Risk Management program minimizes flood damages and disruptions caused by recurring flooding of the Minnesota and Chippewa rivers. Montevideo is located in Chippewa County in western Minnesota, approximately 130 miles west of St. Paul, Minnesota. The city is at the confluence of the Chippewa and Minnesota rivers and is subject to flooding from both rivers.
This dam modification and equipment refurbishment project replaces nine sluice gates and associated operating equipment and installs a permanent stop log dewatering system to provide a dry environment to allow for sluice gate and concrete inspection, maintenance, repair and modifications without impeding all flow through the dam. Lac qui Parle Dam is located on the upper Minnesota River 30 miles east of the South Dakota border. The dam is about seven river miles upstream of Montevideo, Minnesota, and 300 river miles upstream of Minneapolis, Minnesota.
The Lac qui Parle dike and emergency spillway is designed to retain the Lac qui Parle Reservoir during times of flood but is designed for overtopping during extreme events. The overtop elevation of the spillway is 940.75 feet. The Lac qui Parle Dam is located on the upper Minnesota River 30 miles east of the South Dakota border. The dam is about seven river miles upstream of Montevideo, Minnesota. The dike and emergency spillway is adjacent to and west of the dam between the dam and County Hwy 75. The damaged area of the spillway extends approximately 2,500 feet from the dam.
The purpose of this project is to modify the existing Marsh Lake Dam to increase the bio-diversity of the Minnesota River/Lac qui Parle/Pomme de Terre River ecosystem without compromising the flood risk management function of the Marsh Lake Dam. Marsh Lake is located on the Minnesota River between Swift and Lac qui Parle counties near Appleton, Minnesota. The U.S. Army Corps of Engineers owns and maintains Marsh Lake Dam as part of the Lac qui Parle Flood Risk Management project. The fixed-crest dam holds a conservation pool in the upper portion of the Lac qui Parle Reservoir.
The Yellow Medicine River is a major tributary to the Minnesota River located in southwestern Minnesota. The study area for this project includes approximately 685 square miles of mostly agricultural lands across five counties. The Yellow Medicine River and Minnesota River wetland project addresses three high priority concerns: (1) mitigate altered hydrology and minimize flooding; (2) minimize transport of excess nutrients, sediment and bacteria; and (3) preserve groundwater quantity and quality.
The study will assess the problems and opportunities being faced by the Lower Sioux Indian Community on their tribal lands and make recommendations related to erosion along the Minnesota River adjacent to and impacting those lands. The Lower Sioux Indian Community is located south of the Minnesota River in Redwood County, approximately 2 miles south of the city of Morton, Minnesota.
The study will assess the problems and opportunities being faced by the Upper Sioux Community on their tribal lands and make recommendations related to erosion along the Minnesota River adjacent to and impacting those lands. The Upper Sioux Community is located south of the Minnesota River in Yellow Medicine County, approximately four miles south of the city of Granite Falls, Minnesota.
The U.S. Army Corps of Engineers is responsible for maintaining a 9-foot navigation channel as an important component to the inland navigation system. The St. Paul District (MVP) is responsible for maintaining 244 miles of the Upper Mississippi River 9-Foot Channel Navigation Project from the head of navigation at Minneapolis, Minnesota, to Guttenberg, Iowa. The navigation project also includes the lower navigable portions of the Minnesota, St. Croix, and Black Rivers.
