Impaired Water - Lake Menomin (Lake Menomin)
Dunn County, Wisconsin
LC04
2065900
1,008.65
Water is impaired due to one or more pollutants and associated quality impacts.
Notes
On 303d impaired waters list since 1998 for Total Phosphorus; TMDL was approved in 2012.

TP and/or chlorophyll data from the period 2006-2010 were insufficient to assess per 2012 WisCALM. However, the historical chlorophyll and toxin data indicate recreation use impairment, in addition to the previous fish and aquatic life impairment.

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

This water was assessed during the 2016 listing cycle; total phosphorus sample data exceed 2016 WisCALM listing thresholds for the Recreation use and Fish and Aquatic Life use.

This water was assessed during the 2018 listing cycle; new chlorophyll sample data exceeded 2018 WisCALM listing thresholds for the Recreation use.
This water was assessed during the 2020 listing cycle; new total phosphorus sample data exceeded 2020 WisCALM listing thresholds; chlorophyll data only exceeded REC thresholds, not FAL.

Impaired Water Notes
Blue Green sampling was completed from 2004 - 2006 at multiple sites on the lake. SWIMs ID numbers = 173260, 173261, 173262. Monitoring found very high chlorophyll a numbers and detectable concentrations of toxins in water. In most cases monitoring sites were selected to represent worse case conditions in the lake.
