Overview Located between lakes Huron and Erie, Lake St. Clair is the smallest lake in the Great Lakes system. Heart-shaped and shallow (averaging only 10 feet/3 meters deep), the lake requires periodic dredging to ensure bottom clearance for large ships. The northeastern portion of Lake St. Clair is an extensive delta system, the largest within the Great Lakes. The Michigan portion of the delta has been urbanized, while Ontario has set aside much of the wetlands as the Walpole Indian Reservation. Wetland loss from urban and recreational encroachment continues to be a problem on the U.S. side; and in Ontario, many of the wetland areas have been wiped out by agricultural drainage.
