The Connecticut River is the longest river in the New England region of the United States, flowing roughly southward for through four states. It rises 300 yards (270 m) south of the U.S. border with Quebec, Canada, and discharges at Long Island Sound. Its watershed encompasses , covering parts of five U.S. states and one Canadian province, via 148 tributaries, 38 of which are major rivers. It produces 70% of Long Island Sound's fresh water, discharging at per second. The Connecticut River Valley is home to some of the northeastern United States' most productive farmland, as well as the Hartford–Springfield Knowledge Corridor, a metropolitan region of approximately two million people surrounding Springfield, Massachusetts, and Hartford, Connecticut. History The word "Connecticut" is a corruption of the Mohegan word quinetucket and Nipmuc word kwinitekw, which mean "beside the long, tidal river". The word came into English during the early 1600s to name the river, which was also called simply "The Great River". It was also known as the Fresh River, and the Dutch called it the Verse River. Early spellings of the name by European explorers included "Cannitticutt" in French or in English. Pre-1614: American Indian populations Archaeological digs reveal human habitation of the Connecticut River Valley for 6,000 years before present. Numerous tribes lived throughout the fertile Connecticut River valley prior to Dutch exploration beginning in 1614. Information concerning how these tribes lived and interacted stems mostly from English accounts written during the 1630s. The Pequots dominated a territory in the southern region of the Connecticut River valley, stretching roughly from the river's mouth at Old Saybrook, Connecticut, north to just below the Big Bend at Middletown, Connecticut. They warred with and attempted to subjugate neighboring agricultural tribes such as the Western Niantics, while maintaining an uneasy stand-off with their rivals the Mohegans. The Mattabesset (Tunxis) tribe takes its name from the place where its sachems ruled at the Connecticut River's Big Bend at Middletown, in a village sandwiched between the territories of the aggressive Pequots to the south and the more peaceable Mohegans to the north. The Mohegans dominated the region due north, where Hartford and its suburbs sit, particularly after allying themselves with the Colonists against the Pequots during the Pequot War of 1637. Their culture was similar to the Pequots, as they had split off from them and become their rivals some time prior to European exploration of
