National Dam Safety Program. N.J. No Name Number 56 Dam (NJ00804), Whippany River Basin, Malapardis Brook, Morris County, New Jersey. Phase I Inspection Report
Based on visual inspection, available records, calculations and past operational performance, N.J. No Name No. 56 Dam, initially listed as a 'high hazard' potential structure, but reduced to a 'significant hazard' potential structure, as a result of this inspection, is judged to be in fair overall condition. The dam's spillway is considered inadequate because a flow equivalent to 7% of the Spillway Design Flood would cause the dam to be overtopped. To ensure adequacy of the structure, the following actions, as a minimum, are recommended: (1) The spillway's adequacy should be determined by a qualified professional consultant engaged by the owner using more sophisticated 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 following remedial actions should be initiated: Erosion of the channel immediately downstream of the dam should be repaired, and the channel properly stabilized, All trees and adverse vegetation on the embankment should be removed, and the embankment suitably graded and protected against erosion, The concrete wall along the upstream side of the embankment should be repaired, etc.
