Water is impaired due to one or more pollutants and associated quality impacts.
Notes
This segment of the Fox River suffers from low dissolved oxygen due total suspended solids and phosphorus levels. Fish tissue from these waters has also been found polluted with PCBs. This water was assessed during the 2014 listing cycle; biological impairment was observed (i.e. at least one macroinvertebrate or fish Index of Biotic Integrity (IBI) average scored in the poor condition category).
This water was assessed during the 2016 listing cycle; total phosphorus sample data overwhelmingly exceed 2016 WisCALM listing criteria for the Fish and Aquatic Life use and biological impairment was observed (i.e. at least one macroinvertebrate or fish Index of Biotic Integrity (IBI) scored in the poor condition category).
This water was assessed during the 2018 listing cycle; available biological data indicated impairment (i.e. at least one fish Index of Biotic Integrity (IBI) scored in the poor condition category) based on the 2018 WisCALM listing criteria for the Fish and Aquatic Life use and biological impairment was observed

Impaired Water Notes
The Barstow Impoundment is centrally located in downtown Waukesha. The impoundment itself, along with other areas upstream, are on the Federal 303(d) list of impaired waters. Sediment has collected and been concentrated behind the dam. The impoundment has seen an increased use by the public in the recent years with public recreation, boating, park access, and subsistence fishing. The Badgerland Ski Team hold scheduled practices and shows all summer within the impoundment. There is concern with the possible pollutant load in fish and sediment in this area. With such an increased use along this stretch of river, it is important to identify any possible sources of health risks to the public. There is a large sediment buildup behind dam and throughout the impoundment. It is a concern that this sediment is becoming suspended and translocating downstream from multiple sources. Previous sediment sampling indicated sediment toxicity issues. Follow-up sampling, including macroinvertebtrate and fish community sampling, will assist in clarifying the accuracy of the 303(d) listing and documenting impacts to the waterbody and to public health. The follow-up conclusions will also update the fish consumption advisory.
