The Connecticut River flows from the U.S.-Canadian border to Long Island Sound, its 410 miles creating the border between Vermont and New Hampshire, and traversing the midsections of Massachusetts and Connecticut.
In the early days, the river was a main thoroughfare of transportation for the entire New England region. The river provided rich natural resources and a fertile flood plan so that agriculture thrived. The water power of the river and its tributaries allowed a booming Industrial Revolution and growth of towns along its banks. It was on the Connecticut River that the first steamboat was invented and the first submarine was launched.
The Connecticut River is designated as an American Heritage River.
