National Dam Safety Program. Headleys Pond Dam (NJ00790), Delaware River Basin, Tributary to Paulins Kill river, Sussex County, New Jersey. Phase I Inspection Report
Headleys Pond Dam is a gravity dam of stone rubble construction. The spillway which is in the form of a broad crested weir with a concrete cap forms the major portion of the dam. At each end of the spillway section, the dam is formed by earth embankments. Immediately downstream from the dam a paved roadway is located. Discharge from the dam flows under the road by means of a stone arch and concrete box culvert. The culvert has a stone arch section comprising its upstream portion and a concrete box section comprising its downstream portion. The road embankment is braced with steel structural members at each end of the culvert and tied by four steel tie rods. The upstream portion of the brace is partially supported by concrete buttresses at the toe of dam. Based on visual inspection, past operational performance and Phase I engineering analyses, Headleys Pond Dam is assessed as being in fair overall condition. Hydraulic and hydrologic analyses indicate that the spillway is inadequate. Discharge capacity of the spillway is not sufficient to pass the designated spillway design flood (100-year storm) without an overtopping of the dam. The spillway is capable of passing approximately 12 percent of the spillway design flood.
