The Connecticut River Watershed encompasses approximately 28,500 square kilometers making it the largest river ecosystem in New England (Commonwealth of Massachusetts, 2010). The Connecticut River Watershed includes the states of NH, VT, CT, and MA (Commonwealth of Massachusetts, 2010). The Connecticut River begins at the Fourth Connecticut Lake on the border of Canada and flows approximately 660 km to Old Saybrook, CT where it empties into the Long Island Sound. By the time the river reaches the northern border of Massachusetts, it has descended approximately 58 meters (Connecticut River Joint Commissions, 2010).
