Water is impaired due to one or more pollutants and associated quality impacts.
Notes
This portion of Moore (Morris) Creek was evaluated in 2012 for phosphorus and biology. Phosphorus levels were too high and this was reflected in poor biology. Reevaluation in 2020 showed continued high levels of phosphorus, but all seven sites sampled for biology showed fish and bug communities in good health. The 'degraded biological community' impairment was removed form this water in 2020.Pollutant

Impaired Water Notes
Based on the total phosphorus criteria excursions and the corroborating biological assessment (poor scoring fish IBI), this water is proposed as a new listing due to the “degraded biological community” impairment caused by elevated total phosphorus concentrations.

Impaired Water Notes
This water was assessed during the 2020 listing cycle; new total phosphorus sample data exceed 2020 WisCALM listing criteria for the Aquatic Life use, however, available biological data do not indicate impairment (i.e. no macroinvertebrate or fish Index of Biotic Integrity (IBI) scored in the "poor" condition category).
