Lake Superior 1  ... is the largest freshwater lake in the world by surface area and the third largest by volume (Lake Baikal in Siberia and Lake Tanganyika in East Africa contain more water). 2  could hold all the water in the other Great Lakes, plus THREE MORE Lake Eries. 11,000 years ago: Glacial Lake Duluth, the precursor to Lake Superior, forms as the ice sheet retreats northeastward. 2  The lake's torrential outflow near present-day Duluth carves the St. Croix River Valley and feeds the Mississippi River.
Lake Superior is located on the northern edge of Wisconsin and stretches between the Upper Peninsula of Michigan north to Ontario Canada. It also spans west to the eastern edge of Minnesota. Lake Superior is the largest of the Great Lakes by surface area and volume.It is like a mini-freshwater ocean, you can't even see the other side from the Wisconsin shoreline.he land area surrounding the lake also provides Lake Superior with water in the form of rain and snowmelt runoff from Michigan, Minnesota, Wisconsin and Ontario Canada. Most of the land around Lake Superior is heavily forested. Not many people farm near the lake because the temperatures are cool and the soil is poor.
