Although now spelled Wankinco, it was previously written as Wankinquoah, which may have been derived from Wonqun, meaning "crooked".
The Wankinco River originates at East Head Reservoir, a pond in the Myles Standish State Forest, and flows southwards through various impoundments and cranberry bogs to join the Agawam River near the center of Wareham, Massachusetts, after which it forms the Wareham River, forming Wareham's main harbor with a depth of about 12 feet (3.7 m). During a portion of its course, it serves as the boundary between Carver and Plymouth, Massachusetts.
