Mann Lake near Lewiston has been closed due to the presence of harmful algal blooms.
Recent testing revealed concentrations of the toxin-producing algae cyanobacteria that can cause illness to humans and animals. The Idaho Department of Environmental Quality and Public Health – Idaho North Central District issued a health advisory for the lake. According to a news release from the agencies, water from the lake should not be consumed by people, pets or livestock. People and animals should also stay out of the water and avoid activities that lead to contact with it.
The Mann Lake closure is the area’s third body of water to have confirmed algal blooms. Elk Creek Reservoir and Hordeman Pond near Moscow have also been affected by the blooms. (Public Health – Idaho North Central District)
