This 2017 study takes a look at the river from Lake Itasca to downtown Minneapolis, evaluating pollution, fish and other aquatic life.
- The study finds the Mississippi to be a largely healthy river in its northern reaches, owing largely to forested and wetland landscapes it flows through.
- It then acquires significant problems south of St. Cloud, where tributaries from agricultural and more developed landscapes begin to flow into the Mississippi.
MPCA evaluates water quality by measuring and monitoring the health of fish, macroinvertebrates and plants.

The watershed approach is a ten-year rotation for addressing waters of the state on the level of Minnesota’s major watersheds. Since 2007, MPCA and its partners have been implementing this approach as recommended by the Clean Water Council and directed by the state Legislature.
