Notes
Kickapoo River is on the 303(d) list for mercury. In addition, this segment of river was listed for phosphorus during the 2012 listing cycle. This water was assessed for total phosphorus every two-year cycle from 2014 to 2024 and impairment was still found. In 2018, 2020, and 2022 this water was assessed for chloride and no impairment for that parameter was found. Pollutant

Impaired Water Notes
This listing was part of a set removed from the impaired waters list due to a change in fish consumption advisory levels in 2001. In 2001 Wisconsin DNR put into effect a statewide fish consumption advisory for mercury due to atmospheric deposition. Most of the lakes removed from the specific fish consumption advisories list in 2001 were not removed from the impaired waters list even though the thresholds had changed. For the 2020 assessment process WDNR requested delisting of 91 waters with residual mercury listings from prior to 2001. This request was approved by US EPA.
