This project will develop a TMDL for all impaired lakes within the Crow Wing Watershed by furthering data collection in the watershed, analysis of data, allocation calculations, and introducing outreach and stakeholder participation activities.
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%).
This project will continue HSPF watershed model construction beyond the initial framework development. The consultant will add representation of point source discharges to the model. The consultant will also compile flow data for the purposes of calibration and validation. Finally, an initial hydrologic calibration will be performed and submitted for approval.
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.
