where does the connecticut river begin and end
Connecticut River The Connecticut River is the longest river in the New England region of the United States, flowing roughly southward for 406 miles (653 km) through four U.S. states. It rises at the U.S. border with Quebec, Canada, and discharges at Long Island Sound.[3] Its watershed encompasses five U.S. states and one Canadian province, 11,260 square miles (29,200 km2) via 148 tributaries, 38 of which are major rivers.[4] It produces 70% of Long Island Sound's fresh water, discharging at 19,600 cubic feet (560 m3) per second.[4][5]
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.
