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.
Overview. Lake Ontario, the 14th largest lake in the world, is the smallest of the Great Lakes in surface area. It ranks fourth among the Great Lakes in maximum depth, but its average depth is second only to Lake Superior. Lake Ontario lies 325 ft (99 m) below Lake Erie, at the base of Niagara Falls. The falls were always an obstacle to navigation into the upper lakes until the Trent-Severn Waterway, along with the Welland and Erie Canals were built to allow ships to pass around this bottleneck.
