is lake superior the second largest lake in the world
Lake Superior Lake Superior is the largest of the Great Lakes of North America. The lake is shared by the Canadian province of Ontario to the north, the US state of Minnesota to the west, and Wisconsin and the Upper Peninsula of Michigan to the south. It is generally considered the largest freshwater lake in the world by surface area. It is the world's third-largest freshwater lake by volume and the largest by volume in North America.[6] The furthest north and west of the Great Lakes chain, Superior has the highest elevation and drains into the St. Mary's River.
Flathead Lake Flathead Lake (Salish: člq̓etkʷ [3]) is the largest natural freshwater lake by surface area that is west of the Mississippi River in the contiguous United States,[4][5] if one takes Red Lake and Lake of the Woods to be north of the Mississippi River, rather than west of the river.
