Impaired Water - Unnamed (Odana Pond)
Dane County, Wisconsin
LR08
3000513
13.72
Water is impaired due to one or more pollutants and associated quality impacts.
Notes
This water was assessed during the 2012 listing cycle, and total phosphorus and chlorophyll sample data exceed 2012 WisCALM listing criteria for both recreation and fish and aquatic life uses. Chloride levels also exceed the acute toxicity threshold of 757 mg/L in eight sampling events.

This water was assessed during the 2014 listing cycle; total phosphorus sample data overwhelmingly exceed 2014 WisCALM listing thresholds for the Recreation use and Fish and Aquatic Life use and chlorophyll data exceeded REC and FAL thresholds.

This water was assessed during the 2016 listing cycle and chloride sample data exceed 2016 WisCALM listing criteria for the Fish and Aquatic Life use.

This water was assessed during the 2018 listing cycle; new total phosphorus and chlorophyll sample data exceeded 2018 WisCALM listing thresholds for the Recreation use and Fish and Aquatic Life use.

New total phosphorus and chlorophyll data were assessed during the 2020 listing cycle. Both parameters showed conditions unclear for Recreation and Aquatic Life uses.

Impaired Water Notes
Based on the total phosphorus criteria excursions and the corroborating biological assessment (chlorophyll concentration), this water is proposed as a new listing due to the eutrophication and excess algae growth impairments caused by elevated total phosphorus concentrations.
