Lake Superior

Lake Superior is the largest of North America's Great Lakes. It is the largest freshwater lake in the world by surface area with Lake Baikal in Siberia having more volume. (The Caspian Sea is larger, but contains salt water.) Lake Superior has a surface area of 82,000 km² (32,000 sq. mi.), larger than the Czech Republic. It has a maximum length of 350 mi (563 km) and maximum width of 160 mi (257 km). Its average depth is 489 ft (149 m) with a maximum depth of 1,333 ft (406 m). Lake Superior contains 2,935 cubic mi (12,232 cubic km) of water. The shoreline of the lake stretches 2,730 miles (4393 km) (including islands).

It borders Ontario in Canada, and Minnesota, Wisconsin and Michigan in the United States of America. It is an important shipment route for iron ore and is part of the Great Lakes Waterway.

The lake is fed by over 200 rivers. The largest include the Nipigon River, the St Louis River, the Pigeon River, the Pic River, the White River, the Michipicoten River and the Kaministiquia River. Lake Superior drains into Lake Huron by the St. Mary's River. The rapids on the river necessitate the Soo Locks, a part of the Great Lakes Waterway, to move boats over the 25 foot height difference from Lake Huron.

Important towns on Lake Superior include Duluth, Minnesota, Thunder Bay, Ontario, Marquette, Michigan, Sault Ste. Marie, Ontario, and Sault Ste. Marie, Michigan.

The lake was named Lac Supérieur by French explorers because it was the highest in elevation of all the Great Lakes.

The largest island in Lake Superior is Isle Royale National Park.

The Anishinabe were primarily located around the Great Lakes region.
