    Marsh Lake Ecosystem Restoration Project, Minnesota

    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.
  • Minnesota River Basin Integrated Watershed Study

    The Minnesota River had been recognized as highly degraded and a significant sediment source filling Lake Pepin on the Mississippi River and delivering nutrients to the Gulf of Mexico. The Minnesota River Basin Reconnaissance Study, Section 905(b) Analysis recommended an “Integrated watershed, water quality management, and ecosystem restoration analysis, leading to the development of a basin scale watershed management plan” for the Minnesota River Basin. The purpose of this Minnesota River Basin Interagency Study (MRBI Study) was to implement that recommendation by engaging agency partners and using advanced hydrologic modeling and environmental benefit analysis. The intent was to understand water, sediment, nitrogen and phosphorus transport across large landscapes to evaluate hydrologic, sediment and nutrient runoff response to historic, existing and probable future conditions.
