Ohio plans to treat all 13,000 acres of the state's largest inland lake with a chemical to try heading off the toxic algae blooms that become a perennial problem.

Multiple news outlets report that the state's Environmental Protection Agency is trying to pull together $5 million to spread aluminum sulfate, or alum, over Grand Lake St. Mary's in western Ohio.

Officials said in the fall that a test last year over part of the lake was more successful than expected and killed 56 percent of phosphorous in the treated area.

Phosphorous feeds the blue-green toxic algae, which can sicken humans and kill pets and animals.

Tourism declined at the lake in 2010 as illnesses were reported and officials closed the lake to swimming, boating and fishing.
