Lake Superior is the world’s largest freshwater lake by area (31,700 mi2 /82,100 km2). It is also the coldest and deepest of the Great Lakes, with a maximum depth of 406 meters (1,332 feet).
By most measures, it is the healthiest of all the Great Lakes. It is a lake of extraordinary biodiversity, including a plentiful fishery, diverse coastal habitats, and a predominantly forested watershed. The Lake Superior drainage basin is the least developed and least populated of all the Great Lakes. In the state of Michigan, only 2 percent of the state’s population resides within the watershed.
Michigan's Upper Peninsula is a popular tourist destination for those looking to experience the wonders of the 917 miles of Lake Superior shoreline. Lake Superior partners are dedicated to conserving, restoring, and protecting this great resource.
