Water is impaired due to one or more pollutants and associated quality impacts.
Notes
This water was assessed during the 2018 listing cycle; new total phosphorus data were nearly exceeding Fish and Aquatic Life criteria, however new biological (macroinvertebrate and fish Index of Biotic Integrity (IBI) scores) sample data were clearly below 2018 WisCALM listing thresholds for the Fish and Aquatic Life use. Based on biologist's best professional judgment and the TP data this water is proposed for TP listing in 2018.
This water is covered by the Upper Fox & Wolf River Basins TMDL, approved by the US EPA on February 27, 2020. Will be proposed for addition to the UFW TMDL in the 2024 assessment cycle.Pollutant
