Wisconsin River Water Quality Improvement Project
The Wisconsin River Water Quality Improvement Project is a water quality monitoring effort designed to improve conditions in the Wisconsin River and its tributaries by focusing actions to reduce algae blooms and pollution. Improving water quality in the Wisconsin River basin is important to our quality of life, the local and state economy, tourism, property values and recreational opportunities.
From Lake DuBay to Lake Wisconsin, flowages experience nuisance summer algae blooms that limit enjoyment and recreation. Blue-green algae blooms have been reported in Petenwell and Castle Rock flowages at levels above World Health Organization standards. Blue-green algae produce toxins that can be harmful to the health of humans, pets, livestock, and wildlife.
