The issue at hand is an algae bloom in Lake Erie.
The harmful blue-green algae feast on nutrients such as phosphorus and nitrogen, which have been entering Lake Erie en masse recently from farm runoff and sewage-treatment plants. The buildup causes algal blooms, and leads to water that can cause rashes, kidney and liver problems, as well as throw off the ecosystem. Source Wall Street Journal, August 3, 2014
The takeaway here is if you live near a lake, have your water tested, especially if you start seeing a large growth of algae in the water. Coming in contact with the algae can cause issues in issues like diarrhea, vomiting and dizziness. If you are concerned about your own lake water, consider a microcystin analysis – $35.00 .

Microcystins are toxic peptides, produced in large quantities during blooms of the bacteria genus microcystis or planktothrix cyanobacteria (i.e. the genus species Microcystis aeruginosa). Cyanobacterial blooms, often called blue-green algae bloom, can cause oxygen depletion, alter food webs, posing a major threat to drinking and irrigation water supplies, and to fishing and recreational use of surface waters worldwide. Cyanobacteria are one of the oldest microorganisms on Earth, predating predators, 3.5 billion years ago. Source Wikipedia
