Record levels of rain this spring and the resulting agricultural runoff are causing researchers to predict high levels of algae during the summer months that would put recreational water users at risk.
Local water bodies, hit with a combination of fertilizer and increased temperatures, are already beginning to experience algae blooms. These blooms produce toxins like microcystin that can be dangerous to humans and animals in high enough concentrations.
The DNR monitors toxin levels at 38 beaches; if the levels become dangerous, a warning sign is posted.
