Last Updated November 23, 2007
1.5 metres — How deep the water would be if Lake Huron was drained and flooded across the entire North American continent.
6 — The number of Great Lakes if you live in the United States. On March 6, 1998, former U.S. president Bill Clinton signed Senate Bill 927, which recognized Lake Champlain on the border of Vermont and New York as the sixth Great Lake.
6 quadrillion — The number of gallons of fresh water the Great Lakes contain, making up a fifth of the world's fresh surface water. Only the polar ice caps and Lake Baikal in Siberia contain more.
244,000 square kilometres — The total surface area of the Great Lakes. That's roughly the same size as the United Kingdom. The length of the Great Lakes shoreline is equal to almost 44 per cent of the circumference of the Earth, or halfway around the world.
45 million — the number of Canadians and Americans who call the Great Lakes basin home (15 million and 30 million respectively). The population along the lakes' shores is expected to double by 2025, putting additional pressure on the finite resource.
