Where is the deepest part of the Delaware River?

The deepest point of the Delaware is the Big Eddy at Narrowsburg, N.Y., at ~113 ft. The Delaware Water Gap National Recreation Area was one of the top ten visited national park sites in 2020.



The deepest point of the 330-mile-long Delaware River is located at The Big Eddy in Narrowsburg, New York. At this specific bend in the river within the Town of Tusten, the water plunges to a depth of approximately 113 feet (34 meters). This is a dramatic contrast to the rest of the river; most of the non-tidal section ranges between 2 to 20 feet deep. The Big Eddy is famous among geologists and local residents for its powerful circular currents created by the sheer depth and the river's path through the narrow rock-faced valley. While the lower Delaware Estuary near Philadelphia and Wilmington is heavily dredged for industrial shipping, no part of that man-made channel matches the natural, extreme depth found at this scenic spot in the Upper Delaware Scenic and Recreational River area near the New York and Pennsylvania border.
