Ashaway River
The Ashaway River is a river in the U.S. states of Rhode Island and Connecticut. It flows approximately 4 km (2 mi). There are three dams along the river's length. Course 
The river is formed in Hopkinton by the confluence of Parmenter Brook and the Green Fall River, about 500 feet north of Interstate 95, and just a few feet east of the Connecticut state line. From there, it flows south-southwest, briefly entering North Stonington, Connecticut for about 500 feet, before turning southeast and crossing back into Rhode Island and continuing through Hopkinton to its mouth at the Pawcatuck River.
