National Dam Safety Program. Cozy Lake Dam (NJ00309) Passaic River Basin, Rockaway River, Morris County, New Jersey. Phase 1 Inspection Report

摘要

This dam was inspected on 8 November 1979 by Anderson-Nichols and Company, Inc. under contract to the State of New Jersey. The State, under agreement with the U.S. Army Engineer District, Philadelphia, had this inspection performed in accordance with the National Dam Inspection Act, Public Law 92-367. Cozy Lake Dam, initially listed as a high hazard potential structure, but reduced to a low hazard potential structure as a result of this inspection, is judged to be in poor overall condition. The dam's spillway is considered inadequate since a flow equivalent to one percent of the Spillway Design Flood - SDF - would cause the dam to be overtopped. (The SDF, in this instance, is the One Hundred Year Flood.) The low hazard potential classification means that in the event of failure of the dam, no loss of life and minimal economic loss is expected.
