This segment of the South Fork Eau Claire River was evaluated for phosphorus and biology every two-year cycle from 2016 to 2022. Phosphorus levels were found to be too high, which was reflected in poor bug community health. This water is covered by a restoration plan: Healthy Soils and Healthy Waters: A Community Strategy for the Eau Claire River Watershed (expires 2027).
