ST. MARYS, Ohio — Water warnings are going up again at Ohio's largest inland lake after another algae outbreak. The state is telling visitors at Grand Lake St. Marys not to swim or wade in the lake because of the algae. It's the same kind that can produce toxins that shut down the lake last summer.
They're also warning against touching any of the algae on the water.
Officials say the algae bloom is visible across the western Ohio lake.
The state is planning to treat the water this summer in hopes of improving quality.
Marinas, campgrounds and other places that count on tourists lost much of their business last year after the state warned against swimming, boating and fishing. Source
