National Dam Safety Program. Lower Kakeout Dam (NJ00822), Passaic River Basin, Stone House Brook, Morris County, New Jersey. Phase I Inspection Report
Based on visual inspection, available records, calculations and past operational performance, Lower Kakeout Dam, a high hazard potential structure, is judged to be in poor overall condition. The dam's spillway is considered inadequate because a flow equivalent to 3% of the Spillway Design Flood (SDF) would cause the dam to be overtopped. (The SDF, in this instance, is one half of the probable maximum flood). The decision to consider the spillway 'inadequate' instead of 'seriously inadequate' is based on the determination that dam failure resulting from overtopping would not significantly increase the hazard to loss of life downstream from the dam from that which would exist just before failure. To ensure adequacy of the structure, the following are among the recommended minimal actions: (1) The spillway's adequacy should be determined by a qualified professional consultant engaged by the owner using more sophisiticated methods, procedures and studies within six months from the date of approval of this report. Within three months of the consultant's findings remedial measures to ensure spillway adequacy should be initiated; and (2) Within six months from the date of approval of this report the owner should initiate a program to have the observed leakage monitored on a periodic basis by a professional engineer experienced in the design and construction of dams in order to detect any changes in volume or condition. Also, with the impoundment drawn down or diverted, the entire concrete dam structure should be thoroughly inspected and evaluated.
