Impaired Water - Wood Lake (Wood Lake)
Burnett County, Wisconsin
SC11
2649800
521.24
Water is impaired due to one or more pollutants and associated quality impacts.
Notes
This water was assessed during the 2014 listing cycle; chlorophyll sample data exceed 2014 WisCALM listing thresholds for the Recreation use, however, total phosphorus data do not exceed REC thresholds. Total phosphorus and chlorophyll data do not exceed Fish and Aquatic Life thresholds. Additional monitoring is recommended to identify the pollutant causing excess algal growth.

This water was assessed during the 2016 listing cycle; chlorophyll sample data exceed 2016 WisCALM listing thresholds for the Recreation use, however, total phosphorus did not exceed REC thresholds. Total phosphorus and chlorophyll data were clearly below Fish and Aquatic Life listing thresholds.

This water was assessed during the 2018 listing cycle; new chlorophyll sample data exceeded 2018 WisCALM listing thresholds for the Recreation use. Chlorophyll sample data were clearly below listing thresholds for the Fish and Aquatic Life use.
Assessments during the 2020 listing cycle show total phosphorus and chlorophyll levels too high for healthy aquatic communities like plants, fish, and bugs. Both the phosphorus and chlorophyll levels exceeded Recreation and Aquatic Life uses. Eutrophication was added as an impairment in 2020.

Impaired Water Notes
This water was assessed during the 2020 listing cycle; total phosphorus sample data overwhelmingly exceeded 2020 WisCALM listing thresholds for the Recreation use and Aquatic Life use, and chlorophyll data also exceeded REC and FAL thresholds.Based on the most updated information the impairments of Eutrophication were added to the Total Phosphorus listing. The lake was also changed to category 5W in 2020 because it is part of the Implementation Plan for the Lake St. Croix Nutrient Total Maximum Daily Load (2025).
