Lake Superior is the largest freshwater lake in the world by surface area. Lake Baikal in Siberia is larger by volume, as is Lake Tanganyika. The Caspian Sea, while vastly larger than Lake Superior in both surface area and volume, is saline; though presently isolated, in the past, it has been repeatedly connected to, and isolated from, the Mediterranean via the Black Sea.
Lake Superior (48°00’N, 88°00’W) has a surface area of 31,820 square miles (82,414 km²)—which is larger than South Carolina. It has a maximum length of 350 mi (563 km) and maximum breadth of 160 mi (257 km). Its average depth is 483 ft (147 m) with a maximum depth of 1,333 ft (406 m). Lake Superior contains 2,900 mi³ (12,100 km³) of water. There is enough water in Lake Superior to cover the entire land mass of North and South America with a foot (30 cm) of water. The shoreline of the lake stretches 2,726 miles (4385 km) (including islands). The lake's elevation is 600 ft (183 m) above sea level.
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. Marys River. The rapids on the river necessitate the Sault Locks (pronounced "soo"), a part of the Great Lakes Waterway, to move boats over the 25 foot (7.6 m) height difference from Lake Huron.
The largest island in Lake Superior is Isle Royale in the state of Michigan.
The larger towns on Lake Superior include: the twin ports of Duluth, Minnesota and Superior, Wisconsin; Thunder Bay, Ontario; Marquette, Michigan; and the two cities of Sault Ste. Marie, in Michigan and in Ontario. Duluth, at the western tip of Lake Superior, is the most inland point on the Saint Lawrence Seaway.
Among the scenic places on the lake are: the Apostle Islands National Lakeshore; Isle Royale National Park; Pukaskwa National Park; Lake Superior Provincial Park; Grand Island National Recreation Area; Sleeping Giant (Ontario);and Pictured Rocks National Lakeshore.
