National Dam Safety Program. Smithville Dam (NJ 00043) Delaware River Basin, North Branch Rancocas Creek, Burlington County, New Jersey. Phase I Inspection Report.
Abstract
This report cites results of a technical investigation as to the dam's adequacy. The inspection and evaluation of the dam is as prescribed by the National Dam Inspection Act, Public Law 92-367. The technical investigation includes visual inspection, review of available design and construction records, and preliminary structural and hydraulic and hydrologic calculations, as applicable. An assessment of the dam's general condition is included in the report. Based on visual inspection, available records, calculations and past operational performance, Smithville Dam, a high hazard potential structure, is judged to be in fair overall condition. The dam's spillway is considered inadequate because a flow equivalent to 9 percent 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 overtopping failure.
