Located about 80 miles east of New York City, between the North and South Forks at the very tip of Eastern Long Island, the Peconic Bay watershed covers 110,000 acres of land within the five East End Townships. A total of 340 miles of coastline border the Peconic estuarine system from its western boundary at the mouth of the Peconic River to the eastern boundary of Montauk Point. Most of the estuary's primary habitats- sandy beaches, cliffs, dunes, salt marshes, and freshwater wetlands- ramine in fairly natural condition.
