The Watershed of Long Island Sound includes nearly all of Connecticut and western Massachusetts, large swathes of Vermont, New Hampshire and Rhode Island, along with relatively small areas of New York state. (The map is miscolored in two places: the area called "5" is part of the watershed, as is the area called "9" on Long Island; the line dividing Long Island is the southerly limit of the watershed, which includes only a small fraction of the island, along the northern coast)
