The Great Lakes

Lakes Superior, Huron, Michigan, Ontario and Erie make up the largest body of fresh water on Earth, accounting for one-fifth of the freshwater surface on the planet with 6 quadrillion gallons.

The area of all the Great Lakes is 95,160 square miles (246,463 square kilometers) and span 750 miles (1,200 km) from west to east. The square mileage is larger than the state of Texas.
The lakes are on the U.S. and Canadian border, touching Ontario in Canada and Michigan, Wisconsin, Minnesota, Illinois, Indiana, Ohio, Pennsylvania, and New York in the United States. The St. Lawrence River connects Lake Ontario to the Gulf of St. Lawrence, which leads out to the Atlantic Ocean.


As of 2017, more than 30 million people live in the Great Lakes basin, according to the US Environmental Protection Agency. This equates to 10 percent of US residents and 30 percent of Canadian residents. More than 3,500 species of plants and animals inhabit the Great Lakes basin, as well as more than 170 species of fish.
