Course
The river begins in the swamps west of Primrose Pond in North Smithfield and runs southeast past Primrose Pond to Stillwater Reservoir. Below the reservoir, the river continues southeast, providing water to numerous ponds, until going under Providence Place mall and joining the Moshassuck River in front of the One Citizens Plaza building in downtown Providence to form the Providence River. The lower part of the river, below Rising Sun Dam in Olneyville is tidal.
East of Interstate 95, the Woonasquatucket's original riverbed no longer exists and it has been diverted into a man-made channel underneath Providence Place Mall and through Waterplace Park. In Waterplace Park, the Woonasquatucket River is also used as part of Waterfire.
