History of Lake Superior Day
According to Lake Superior Magazine, Lake Superior Day was started in the 1990s by lake lovers in Thunder Bay, Ontario. It was then revived a decade later by the late Bob Browne of Superior, who had served in the Lake Superior Binational Forum. Lake Superior is the only one of the Great Lakes which is celebrated annually with its own day, on the third Sunday in July. With 10% of all the world’s fresh surface water in the backyard of Duluth, that’s truly a cause for celebration as well as for learning how to preserve and respect Lake Superior.
Lake Superior is the world’s largest freshwater lake by surface area — 31,700 square miles. It’s the third-largest lake by volume, after Lake Tanganyika (the second largest) in eastern Africa and Lake Baikal (the largest) in Siberia. It holds 10% of the world’s fresh surface water, and its cold waters reach a depth of 1,332 feet. Lake Superior is shared by Ontario to the north, Minnesota to the west, as well as Wisconsin and the Upper Peninsula of Michigan to the south. If the waters of all of the other four Great Lakes combined, Lake Superior alone still holds more water — superior, indeed.
Lake Superior is said to be the cleanest, clearest, and coldest of the Great Lakes. While providing clean drinking water, Lake Superior supports local shipping, commercial fishing, and recreational industries. Each of the 600,000 people living in the Lake Superior basin uses the lake’s water for daily needs. Also, the lake is essential for other creatures like fishes, birds, and plants.
