Due to the presence of algal toxins found within the water of a number of inland lakes across Ohio and Lake Erie, Ohio EPA, Ohio Department of Natural Resources (ODNR) and Ohio Department of Health (ODH) are releasing a comprehensive list of updated sampling results for algal toxins including microcystin, anatoxin-a, cylindrospermopsin and saxitoxin. All state parks remain open.
Grand Lake
Microcystin levels at Grand Lake St. Marys (Auglaize and Mercer counties) continue to be low. Samples taken this week at Campground, West and East beaches had levels ranging from 4.9 to 6.5 ppb, with East Beach the highest. Anatoxin-a was at the lowest detection limit (0.05-0.1 ppb) at East and West beaches and was not detected at Camp Beach. Saxitoxin and cylindrospermopsin were not detected. The toxin advisory remains in place.
