National Dam Safety Program. Cumberland Pond Dam, (NJ00824). Delaware River Basin, Manumuskin River, Cumberland County, New Jersey. Phase 1 Inspection Report.
Abstract
The dam is an earth embankment supporting the roadway of N.J. Highway Route 49. A timber stoplog spillway is located at the upstream end of a concrete bridge near the left end of the dam. The outlet works is formed by the stoplogs which comprise the spillway. Based on visual inspection, past operational performance and Phase I engineering analyses, Cumberland Pond Dam is assessed as being in good 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 (SDF) without an overtopping of the dam. (The SDF of Cumberland Pond Dam is equal to one-half the probable maximum flood.) The spillway is capable of passing approximately 26 percent of the probable maximum flood or 52 percent of the SDF. Therefore, the owner should engage a professional engineer experienced in the design and construction of dams in the near future to perform more accurate hydraulic and hydrologic analyses relating to spillway capacity.
