When state boundries were originally set (many moons ago), a portion of the boundry between Delaware and New Jersey was defined as the eastern side of the Delaware River, to just south of Reedy Island, DE, then westerly out to the 'center' of the river, to continue south into Delaware Bay. Subsequently, land mass was added (by filling) into the Delaware River, at Salem Nuclear Plant. This land mass projected north, crossing this (imaginary) east - west state line, putting it's tip on the Delaware side of line. This can be seen on most state maps of the area about, seven miles south of Salem, New Jersey.
