Notes
This segment of the Root River was evaluated for phosphorus and biology in 2014 and phosphorus levels were found to be too high. This water was reevaluated for phosphorus in 2020 and 2024; levels were still too high. This water is covered by a restoration plan: Root River Watershed Restoration Plan (expires 2024). Evaluation in the 2022 cycle for chloride and bug data showed good conditions.Pollutant

Impaired Water Notes
This water was assessed during the 2020 listing cycle; new total phosphorus sample data exceed 2020 WisCALM listing criteria for the Fish 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. This lake is covered by the following restoration plan and was classified as Category 5W as a result: Root River Watershed Restoration Plan (2024).
