Covering more than 94,000 square miles and draining more than twice as much land, these Freshwater Seas hold an estimated 6 quadrillion gallons of water, about one-fifth of the world's fresh surface water supply and nine-tenths of the U.S. supply.

Fun Facts
Spread evenly across the contiguous 48 states, the lakes' water would be about 9.5 feet deep.

All five of the Great Lakes are among the world's 18 largest lakes by area and volume.

The Great Lakes and islands within them have more than 10,000 miles of coastline.
