FOND DU LAC, Wis. (AP) -- The University of Wisconsin-Milwaukee is testing the water quality of Lake Winnebago to find out whether blue-green algae produces toxins in drinking water.
The state's largest inland lake provides water for more than 200,000 people in Oshkosh, Appleton, Neenah and Menasha.
The Reporter Media reports the Wisconsin Department of Natural Resources is also warning swimmers and boaters to watch out for blue-green algae blooms.
The agency says bloom reports typically spike in August because the water has warmed up and conditions are most conducive for algae growth.
Some algae species produce toxins that can cause ailments including stomach aches, flu-like symptoms, rashes and hives.
The research is being funded by a $750,000 grant from the National Institution of Environmental Health Sciences and the National Science Foundation.
