Connecticut River rises in northern New Hampshire, and forms the boundary between that state and Vermont. It then cuts across Massachusetts and Connecticut to empty into Long Island Sound. The river is 407 miles (655 kilometers) long. Industrial towns grew up along its middle course to take advantage of the power from its falls and rapids. Today, hydroelectric projects still produce electric power for area residents and businesses. Traditional industries along the river have included paper mills, sawmills, and textile mills.
