Water is impaired due to one or more pollutants and associated quality impacts.
Notes
Jim Kreitlow (NOR) documented dissolved oxygen standards violations while sampling the lake in the mid 1990s. Dissolved oxygen concentrations below 5 mg/l were generally found during the early morning hours, probably a result of algae respiration. Values for pH above 9.0 were documented in 1996, 1997 and 1998.

Impaired Water Notes
Dissolved oxygen concentrations below 5 mg/l were generally found during the early morning hours, probably a result of algae respiration. Values for pH above 9.0 were documented in 1996, 1997 and 1998.
The cause of these impairments is likely the result of excessive nutrient loading (phosphorus) from point and nonpoint sources in the watershed. As a result, the flowage is very eutrophic with abundant algae growth. The University of Wisconsin Stevens Point completed a nutrient and water budget modeling study in 1999 on Petenwell Flowage. Water chemistry data collected in 1996 indicates chlorophyll a concentrations ranged from 8.4 to 66.6 ug/l and total phosphorus concentrations ranged from 85 to 171 ug/l.

Impaired Water Notes
Previous sampling has found high levels of 2,3,7,8-TCDD and 2,3,7,8-TCDF in sediments. PCBs and mercury have also been detected at limited sampling sites. Currently, a fish consumption advisory exists on the flowage for PCBs, dioxin and mercury.
Monitoring conducted in 2003 found frequent pH exceedances during the summer.
