Water is impaired due to one or more pollutants and associated quality impacts.
Notes
Lake Chetek was documented as having hypereutrophic total phosphorus levels in 1996. Sediments and nutrients which may drive algae blooms to the point of being dominated by blue-greens which have the potential to produce toxins as well as suppress D.O. levels. Much of this can be attributed to nonpoint source runoff from agricultural sources. This water is covered by a watershed plan: A Water Quality Strategy for the Land and Waters of the Red Cedar River Basin (expires 2026).Pollutant
