The data collected in this workplan is the foundation for an accurate TMDL allocation and accurate implementation strategy design. Current and historic phosphorus inputs will be calculated and evaluated as to source. Nutrient and algal history and trends in sedimentation will be reconstructed to identify ecological changes that have occurred in the lakes both recently and historically.
The Crow Wing River Watershed consists of approximately 1,959 square miles in the north to north central portion of the Upper Mississippi River Basin in Central Minnesota. The watershed encompasses all or parts of Becker, Cass, Clearwater, Crow Wing, Hubbard, Morrison, Otter Tail, Todd and Wadena Counties. The dominant land use within the watershed is forested (41%), agriculture (32%), grass, shrub and wetland make up 17%, water (7%) and urban (3%).
Approximately 70 percent of all Minnesotans rely on groundwater as their primary source of drinking water. Wells used for drinking water must be properly sealed when removed from service to protect both public health and Minnesota’s invaluable groundwater resources. The Minnesota Department of Health protects both public health and groundwater by assuring the proper sealing of unused wells.
Clean Water funds are being provided to well owners as a 50% cost-share assistance for sealing unused public water-supply wells.
