The Platte River is listed by MPCA as impaired for fish bioassessments and water temperature. It is a recreational river used by many swimmers, paddlers and flotation users. The Platte is a major tributary to the Mississippi River which is the primary drinking water supply from St. Cloud to the Gulf. The Mississippi River segment immediately below Royalton is also impaired and therefore remedial efforts above are imperative.
The goal of this project is to decrease nutrient loading in the lake and rivers within the Swan River Watershed. The Local Water Plan currently identifies surface water contamination and declining water clarity as a priority concern of Todd County. Agency members specifically identified the Swan River Watershed as an area of high priority for restoration efforts. Big Swan Lake is specifically mentioned for its roosting site for purple martins and for the unique wildlife resources it makes available in this subwatershed.
