According to new draft reports, surface waters in the Mississippi River-Sartell Watershed are in fair condition but phosphorus and E. coli pollution are threatening aquatic life and recreation in several streams and lakes, the Minnesota Pollution Control Agency reported Monday, Sept. 14.
In addition, a stretch of the Platte River was classified as an exceptional use stream and is a focus for protection.
The Mississippi River-Sartell Watershed has 880 miles of rivers and streams, 232 lakes, and includes parts of Benton, Crow Wing, Mille Lacs, Morrison, Stearns, and Todd counties.
The first report, known as a total maximum daily load, establishes the amount of each pollutant that a water body can accept and still meet water quality standards, and the amount of reductions needed in current levels of pollution. Monitoring results indicate that 16 stretches of streams are not meeting water quality standards for aquatic life due to excess phosphorus and nitrates, and low dissolved oxygen, and 24 stream sections are not meeting aquatic recreation standards due to E. coli or fecal coliform bacteria.
The second report, a watershed restoration and protection strategy, is required by the state Clean Water Legacy Act and uses the total maximum daily load, monitoring results, and other information to develop strategies for addressing all pollution sources in the watershed. The Mississippi River-Sartell a watershed restoration and protection strategy report recommended ways to reduce excess bacteria in streams, including:
Feedlot management practices,
Septic system maintenance and upgrades,
Stormwater control measures in cities and towns.
Strategies for reducing phosphorus in lakes include internal lake and shoreline management, cover crops and living cover, low-till or no-till practices on farm fields, nutrient and fertilizer management, buffers, and septic system maintenance and upgrades.
The reports are part of the MPCA’s approach to gauging the health of Minnesota’s 80 major watersheds, each of which will have an approved comprehensive watershed management plan by 2025. After intensive watershed monitoring, the agency and partners evaluate biological conditions in lakes and streams. Waters that fail to meet standards are placed on the Impaired Waters List, and the agency develops information and strategies that are used to restore impaired waters and protect healthy ones.
While several bodies of water in the watershed do not meet water quality standards, a number of streams and lakes are demonstrating improving trends in water clarity. The watershed’s water bodies provide important recreational and economic benefits to citizens and visitors. Watershed conditions are also critical to downstream waters, where both St. Cloud and the Twin Cities draw on the Mississippi River for drinking water.
