Phase 2 of the Mississippi River - Brainerd Watershed Restoration and Protection Strategy (WRAPS) project will: develop the WRAPS report and the Total Maximum Daily Load (TMDL) study, which allocates pollutant load reductions for impaired waters; implement a civic engagement plan; and develop watershed modeling scenarios to help understand implementation needs in the watershed.
The project goal is to conduct water chemistry monitoring at four subwatershed sites and one basin site in 2016, 2017, 2018 and 2019. Water chemistry monitoring will be conducted at a wide range of flow conditions with emphasis of collecting samples during periods of moderate and high flows after runoff events, as defined in the Watershed Pollutant Load Monitoring Network (WPLMN) Standard Operating Procedures and Guidance. The data collected will be submitted to the Minnesota Pollution Control Agency (MPCA) and used in the FLUX32 model for calculating pollutant loads.
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.
