Undammed
The main stem of the Delaware is the longest free-flowing (undammed) river east of the Mississippi. Tributary river flows are controlled by upstream reservoirs operated by the City of New York. Under a 1954 Decree signed by the United States Supreme Court, in times of normal precipitation and runoff, the average daily flow at the northernmost river gauge in Montague, New Jersey must be maintained at 1,750 cubic feet per second.
Hawk’s Nest Drive, located along the New York State Route 97 Upper Delaware Scenic Byway in the Town of Deerpark, is a favorite filming location for television commercials and movies thanks to its exciting S-curves between a natural rock face and man-made rock walls and majestic views of the Delaware River some 200 feet below from a series of motorist pull-off areas.
