Water is impaired due to one or more pollutants and associated quality impacts.
Notes
The Petenwell and Castle Rock Flowages Comprehensive Management Plan was completed in 1996. This report indicates severe algal blooms cause periodic shifts in dissolved oxygen. During photosynthesis, dissolved oxygen values are high (11-12 mg/l) but during respiration, they can drop below 5.0 mg/l (Storet, 1992 was referenced). The report also indicates blue-green algae are the dominant phytoplankton in the Petenwell and Castle Rock Flowages. The report also references sediment sampling has been completed in both flowages, however additional sampling is recommended. Previous sampling found high levels of 2,3,7,8-TCDD and 2,3,7,8-TCDF in the sediments. PCBs and mercury have also been detected at limited sampling sites. Currently, a fish consumption advisory exists on the flowage for PCBs, mercury. New fish tissue data in the 2016 listing cycle indicates that the Dioxin listing can be removed.
This water was assessed during the 2018 listing cycle; new macroinvertebrate sample data exceeded 2018 WisCALM listing criteria for the Fish and Aquatic Life use (i.e. at least one macroinvertebrate Index of Biotic Integrity (IBI) average scored in the poor condition category).

Impaired Water Notes
The Wisconsin River at Castle Rock Flowage, WBIC 1179900, incorrectly had pH and nitrogen as pollutant/impairment. The correct listing is now shown (same for the assessment unit Castlerock Flowage). Pollutant: TP, Impairment: Eutrophication. The nitrogen/Elevated pH was listed in error and should have been corrected in 2008. Most likely it was originally listed for nutrients, and accidentally someone chose N instead of P.
