1 Lake Erie is the twelfth largest lake in the world (in area), and its border includes four states (New York, Pennsylvania, Ohio, and Michigan) and one Canadian Province (Ontario).  Lake Erie is the southernmost, shallowest, warmest, and most biologically productive of the five Great Lakes.
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.
