State officials posted a public health advisory at Kiser Lake State Park in Champaign County on Friday after sampling showed a high level of toxin at the popular recreational site.
The recreational health advisory indicates that an algal bloom has been detected, and the Ohio Department of Health says swimming and wading aren't recommended for children, pregnant or nursing women, those with certain medical conditions and pets.

The Ohio Department of Natural Resources conducted sampling at the lake, and detected levels of microsystin, a toxin produced by the algae. Sampling found levels of about 11.7 parts per billion, according to information from the state’s BeachGuard website.
Any level detected higher than 6 ppb prompts a health advisory, state officials said.
