Lake Michigan (/ˈmɪʃɪɡən/ ⓘ MISH-ig-ən) is one of the five Great Lakes of North America. It is the second-largest of the Great Lakes by volume (1,180 cu mi; 4,900 km3) and depth (923 ft; 281 m) after Lake Superior and the third-largest by surface area (22,300 square miles; 57,757 km2), after Lake Superior and Lake Huron. To the east, its basin is conjoined with that of Lake Huron through the wide and deep Straits of Mackinac, giving it the same surface elevation as its eastern counterpart; hydrologically, the two bodies are a single lake that is, by area, the largest freshwater lake in the world.
