National Dam Safety Program. Openaka Lake Dam (NJ00780), Passaic River Basin, Den Brook, Morris County, New Jersey. Phase I Inspection Report
Openaka Lake Dam consists of a stone masonry spillway section with earth embankments at each end. The spillway section comprising about one-third the length of the dam is constructed with a concrete cap on its top. Immediately downstream from the spillway section is a steel roadbridge. A paved roadway runs along the crest of the embankments and over the steel bridge. A low level outlet transversely penetrates the center of the spillway and discharges downstream from the dam just to the right of the downstream channel. Based on visual inspections, past operational performance and Phase I engineering analyses, Openaka Lake Dam is assessed as being in fair overall condition. Hydraulic and hydrologic analyses indicate that the spillway is inadequate. Discharge from 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 13 percent of the SDF.
