The Seekonk River is a tidal extension of the Providence River. It flows approximately 5 miles. Most historical scholars agree that the name is derived from two Native American words, sucki (meaning black) and honc (meaning goose).
The river begins where the Blackstone River reaches sea level below Pawtucket Falls. From there it flows due south between Providence and East Providence, picks up the flow from the Ten Mile River, and eventually flows into the Providence River between Bold Point and India Point. The Seekonk River is the northernmost point of Narragansett Bay tidewater.
