The Lakes

The Great Lakes -- Erie, Huron, Michigan, Ontario and Superior -- are among the most important bodies of water in the world. They are the largest readily accessible source of freshwater on Earth – roughly 20 percent of the total supply -- and contain more than 80 percent of North America’s surface water supply.
