where does the blackstone river start and end
Blackstone River The river is formed in Worcester, Massachusetts by the confluence of the Middle River and Mill Brook. From there, it follows a rough southeast course through Millbury, Sutton, Grafton, Northbridge, Uxbridge, Millville, and Blackstone. It then continues into Rhode Island, where it flows through Woonsocket, Cumberland, Lincoln, Central Falls, and Pawtucket, where the river then reaches Pawtucket Falls. After that, the river becomes tidal, and flows into the Seekonk River just north of Providence. Other tributaries join the Blackstone along the way, such as the West and Mumford River, at Uxbridge, and The Branch River in North Smithfield.
