The Eastern Continental Divide, in conjunction with other continental divides of North America, demarcates two watersheds of the Atlantic Ocean: the Gulf of Mexico watershed and the Atlantic Seaboard watershed. Prior to 1760, the Divide represented the boundary between British and French colonial possessions in North America. The ECD runs south-southwest from the Eastern Triple Divide in Pennsylvania to the watershed of the Kissimmee River, which drains via the Lake Okeechobee and the Okeechobee Waterway to both the Gulf of Mexico and the Atlantic Ocean.
