Connecticut River

geography Maturity 7-9 Next article →

The Connecticut River is a very important river in the New England region of the United States. It is the longest river in that entire region. The river flows mostly toward the south through four different states. It begins about 300 yards south of the border with Quebec, Canada. Eventually, the river flows into the Long Island Sound. This happens between the towns of Old Saybrook and Old Lyme in Connecticut.

The river works like a massive water system for the land. Its watershed covers parts of five U.S. states and one Canadian province. Many smaller rivers, called tributaries, flow into it. There are 148 of these, and 38 are major rivers. The Connecticut River provides 70% of the fresh water for Long Island Sound. This constant flow of water helps the land stay green and healthy.

Long ago, many different tribes lived in the river valley. People lived there for 6,000 years before modern history began. The Pequot tribe lived in the southern part of the valley. The Mohegan tribe lived further north near where Hartford is now. The Pocomtuc tribe lived near Springfield, Massachusetts. They lived in villages like Agawam, which means "landing place."

European explorers arrived in the area in the early 1600s. A Dutch explorer named Adriaen Block charted the river in 1614. He called it the "Fresh River" because it was not salty. Later, Puritan settlers arrived to build new towns. They founded the city of Hartford in 1635. They also founded the city of Springfield in 1636.

Today, the river valley is a very busy and productive place. The soil is rich, so it is great for farming. Many people live in the Hartford–Springfield Knowledge Corridor. This area has about two million people living around the two cities. The river also helped cities grow during the Industrial Revolution. Many mills used the river's water and falls for power.
