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]
Ohio River The Ohio River, which streams westward from Pittsburgh, Pennsylvania, to Cairo, Illinois, is the largest tributary, by volume, of the Mississippi River in the United States. At the confluence, the Ohio is considerably bigger than the Mississippi (Ohio at Cairo: 281,500 cu ft/s (7,960 m3/s);[2] Mississippi at Thebes: 208,200 cu ft/s (5,897 m3/s)[3]) and, thus, is hydrologically the main stream of the whole river system.
