Lake St. Clair (French: Lac Sainte-Claire) is a fresh-water lake named after Clare of Assisi that lies between the Province of Ontario and the State of Michigan, and its midline also forms the boundary between Canada and the United States of America. Lake St. Clair includes the Anchor Bay along the Metro Detroit coastline. This lake is situated about 6.0 miles (9.7 km) northeast of Detroit, Michigan and Windsor, Ontario. With about 430 square miles (1,100 km2) of water area, this lake is part of the Great Lakes System. It links the Great Lakes system, but is rarely included in the listings of the Great Lakes. There are ongoing proposals for its official recognition as a Great Lake, which would affect its inclusion in scientific research projects, etc., designated as being for "The Great Lakes". Along with the St. Clair River and Detroit River, Lake St. Clair connects Lake Huron (to its north) with Lake Erie (to its south).
