The Minnesota Pollution Control Agency evaluation of the Minnesota River shows there's still much work to be done for the health of the Minnesota River. The monitoring and evaluation work encompasses most of the river, from Big Stone Lake to where it meets the Mississippi in St. Paul. The study led to these primary conclusions:
- Overall, the Minnesota River is unhealthy. Sediment clouds the water, phosphorus causes algae, nitrogen poses risks to humans and fish, and bacteria make the water unsafe for swimming.
- Too much water flowing into the river plays a big part in all these problems. There’s more rain, more artificial drainage, and not enough places to store this water.

Water quality in the Lower Minnesota River Watershed has persistent problems with excess phosphorus, sediment, bacteria, and other contaminants, according to a new MPCA report.

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.
