Is it safe to fish and swim?

How can you determine if your favorite local lake is safe for fishing and swimming? In Minnesota, the Pollution Control Agency (MPCA) works with local government and volunteers to monitor water quality in lakes, rivers, and streams, and maintains a list of water bodies that are “impaired” by one or more pollutants. Common impairments include high levels of mercury in fish (a concern if you are fishing), as well as nutrients that cause algal blooms, bacteria that make people sick, and sediment that clouds the water (all of which are concerns if you are swimming).
