Water is impaired due to one or more pollutants and associated quality impacts.
Notes
This water was assessed during the 2016 listing cycle; total phosphorus sample data exceed 2016 WisCALM listing criteria for the Fish and Aquatic Life use and biological impairment was observed (i.e. at least one macroinvertebrate or fish Index of Biotic Integrity (IBI) scored in the poor condition category). The regional biologist recommends this water for listing for degraded habitat and Sediment/Total Suspended Solids.

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 new biological data (i.e. macroinvertebrate or fish Index of Biotic Integrity (IBI) already scored in previous water evaluation cycles) were available to assess further biological impairment.
