List of rivers of Connecticut facts for kids
Connecticut is a state in the United States known for its many rivers. Most of these rivers flow into a large body of water called Long Island Sound. From there, their waters mix with the huge Atlantic Ocean. A few rivers in the very eastern part of Connecticut flow into Block Island Sound instead.
This article lists the main rivers in Connecticut. It's organized by where the rivers drain their water, starting from the east and moving west. Think of a river basin as a big bowl where all the rain and water eventually flow into one main river. Smaller rivers that flow into a bigger one are called "tributaries."
