Catching the flush of pollutants is the job of the Watershed Pollutant Load Monitoring Network. This network of state and local partners monitor the quality of major rivers throughout Minnesota.
The MPCA uses the data in studies and watershed restoration and protection strategies it develops with local partners. Local partners then use the data for planning and to implement the best strategies in priority locations.
Their work is important for detecting whether water quality is getting better or worse, tracking the impact of restoration work, and identifying sources of pollution and ways to reduce them.
