Notes:
a Measured at Low Water Datum.b Land Drainage Area for Lake Huron includes St. Marys River.
Lake Erie includes the St. Clair-Detroit system.
Lake Ontario includes the Niagara River. c Including islands. d These totals are greater than the sum of the shoreline length for the lakes because they include the connecting channels (excluding the St. Lawrence River).
