The Delaware River is the last major free flowing river on the east coast. Originating in the Catskill Mountains of New York, the East and West branches of the Delaware River meet in Hancock, New York and form the main stem of the river. The River flows a total of 375 miles from the Catskills to the sea. Its watershed, includes 12, 765 square miles in portions of four states -- New York, New Jersey, Pennsylvania, and Delaware -- and is home to nearly 6 million people. The Delaware flows through forested mountains, farmlands, small historic towns, suburban sprawl, urban development, industrial complexes, and extensive wetlands before reaching the Atlantic Ocean. While the River drains only 1% of the land, it supplies water to 7% of the population of the United States, approximately 20 million people, many of whom live outside the watershed. The Delaware has been called a "Servant of many masters"-- its uses include recreation, industrial plants, shipping, and drinking water. A wing dam is a manmade barrier that, unlike a conventional dam, only extends partway into a river. These structures force water into a fast-moving center channel which reduces the rate of sediment accumulation, while slowing water flow near the riverbanks.
