Microcystin Data

The Lilly Center collects water samples from open water on Kosciusko County’s twelve all-sport lakes and Center and Pike lakes, along with the public swimming beaches at Center, Pike, Syracuse, Waubee, Webster and Winona lakes. Samples are processed and analyzed for microcystin, a blue-green algae toxin relevant in the county. Toxin results will be updated on this page every week. To learn more about microcystin and pet and human health, visit our blue-green algae research hub and the Indiana Department of Environmental Management’s (IDEM) blue-green algae informational site.

As a general guideline, refrain from recreating in water undergoing a blue-green algae bloom! This will often look like a green paint slick on the surface or a pea-soup appearance.
