Flowing for 410 miles far; from Canada to Long Island Sound, Connecticut River is the longest river in New England.

With its watershed as wide as 11,000 square-miles, it also stands as the largest watershed in New England.  

Even more, the watershed is one of fourteen American Heritage Rivers.

Along with its journey from Canada through Vermont, New Hampshire, Massachusetts, and Connecticut, 38 tributaries contributes
to the flow of the river.

The flow accounts for 70 percent of the freshwater inflow to Long Island Sound, delivering a daily average flow of nearly 16,000 cubic feet per second. 

The lower 60 miles of the river are tidal, with the boundary between salt and freshwater about 17 miles from its mouth under normal condition.
