Warren River

The Warren River, historically called the Sowams River, is a tidal extension of the Palmer River in the U.S. state of Rhode Island. It flows approximately 6.5 km (4 mi). There are no dams along the river's length.

Course
The river begins where the Palmer River widens just over the border from Swansea. From there it flows due south between the towns of Barrington and Warren to its confluence with the Narragansett Bay.
