Water is impaired due to one or more pollutants and associated quality impacts.
Notes
Total phosphorus data from this water were evaluated during the 2012 listing cycle. Some of the evaluated data were collected during extreme weather events, leaving insufficient representative data available to assess. Therefore, additional representative data will be collected during more normal conditions before making an assessment decision.
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).
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, new biological data (i.e. at least one macroinvertebrate Index of Biotic Integrity (IBI) already scored in previous water evaluation cycles) were available to assess further biological impairment.Pollutant
