The Delaware River is one of the last large free-flowing rivers left in the contiguous 48 states - one of the last major rivers without any dams or control structures on its main stem. It is considered to be a river of exceptional water quality. For 40 miles the Middle Delaware River passes between low forested mountains with barely a house in sight. Then the river cuts through the mountain ridge to form the famed Water Gap.
