Lakes common in US and in Canada?

Answer 1

Although there are likely many other minor lakes that fall on the border between the United States and Canada, perhaps the most significant lakes common to both the U.S. and Canada are in the Great Lakes area.

Starting from the Manitoba-Ontario border, these lakes include:
Lake of the Woods (Manitoba, Ontario and Minnesota), Rainy Lake (Ontario and Minnesota), Lake Superior (Ontario, Minnesota and Michigan), Lake George, Munuscong Lake, Lake Huron, Lake St. Clair (Ontario and Michigan), Lake Erie (Ontario, Michigan, Ohio, Pennsylvania and New York) and Lake Ontario (Ontario and New York).

In fact, of the 5 Great Lakes (Superior, Michigan, Huron, Ontario and Erie) only Lake Michigan is fully in the U.S.A. and therefore does not form part of the border between Canada and the United States.

Other important or famous waterways on the United States-Canadian border are Lake Champlain, the Niagara River (and its Niagara falls), the St. Lawrence River, the Straits of Georgia and Juan de Fuca (between Washington and British Columbia) and parts of the Arctic including Beaufort Sea, where maritime territory disputes still exist between the two countries.
