Impaired Water - Sinissippi Lake (Hustisford) (Sinissippi Lake)
Dodge County, Wisconsin
UR08
859900
1,647.77
Water is impaired due to one or more pollutants and associated quality impacts.
Notes
The lake was listed in 2002 due to eutrophication and degraded habitat impairments caused by total phosphorus and sediment/TSS, respectively. TMDL approved 2011.

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; total phosphorus sample data overwhelmingly exceeded 2016 WisCALM listing thresholds for the Recreation use and Fish and Aquatic Life use, and chlorophyll data overwhelmingly exceeded FAL thresholds and exceeded REC thresholds.

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.
