Ohio’s largest inland lake will be treated this spring with a chemical aimed at heading off the toxic algae blooms that have hurt tourism.
The state says it will treat all 13,000 acres of Grand Lake St. Marys, instead of just part of it, with aluminum sulfate beginning April 1.
The alum is used to neutralize phosphorous, which gets into the lake from manure and chemical runoffs.
The phosphorous feeds blue-green toxic algae, which produces a nerve toxin that can sicken humans and kill pets and other animals.
