Notes
This water was evaluated every two year cycle from 2014 to 2018; elevated phopshorus was found each cycle and it was listed on the Impaired Waters List. In 2020 the phophorus listing was placed on the Waters In Restoration List (Category 4) because it is covered by the Upper Fox & Wolf Basins TMDL, approved by the US EPA in February 2020. New water quality data reviewed in the 2024 cycle indicated no additional pollutants.Pollutant
