Water is impaired due to one or more pollutants and associated quality impacts.
Notes
This segment of the Black River is impaired by low levels of dissolved oxygen, caused primarily by non-point source pollution.
This water was assessed during the 2018 listing cycle; new total phosphorus sample data exceed 2018 WisCALM listing criteria for the Fish and Aquatic Life use, however, no biological data (i.e. no macroinvertebrate or fish Index of Biotic Integrity (IBI) scores) were available to assess biological impairment.Pollutant
