Notes
The Chippewa River was put on the impaired waters list in 1998 for PCBs in fish tissue and sediment. It was also listed for mercury from 1998 to 2008; new fish tissue samples showed mercury levels below the statewide advisory level. This river segment has been evaluated for phosphorus in 2014 and every two years between 2018 and 2024; levels were appropriate for healthy aquatic communities like plants, bugs, and fish. Evaluated bug communities in 2018 and 2020 confirmed this.
