Encyclopedic overview

Lake St. Clair (French: Lac Sainte-Claire) is a freshwater lake that lies between the Canadian province of Ontario and the U.S. state of Michigan. It was named in 1679 by French Catholic explorers after Saint Clare of Assisi, on whose feast day they first saw the lake.

It is part of the Great Lakes system (although not considered one of the five Great Lakes), and along with the St. Clair River and Detroit River, Lake St. Clair connects Lake Huron (to the north) with Lake Erie (to the south). It has a total surface area of about 430 square miles (1,100 km) and an average depth of just 11 feet (3.4 m); to ensure an uninterrupted waterway, government agencies in both countries have maintained a 30-foot-deep (9.1 m) shipping channel through the shallow lake for more than a century.
