National Dam Safety Program. Cedar Lake Dam (NJ00805), Passaic River Basin, Tributary to Rockaway River, Morris County, New Jersey. Phase I Inspection Report.
Abstract
Based on visual inspection, available records, calculations and past operational performance, Cedar Lake 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 good overall condition and the spillway is considered adequate. To ensure the adequacy of the structure the following remedial actions are recommended: (1) Within one year from the date of approval of this report the owner should initiate a program of monitoring the observed seepage on a periodic basis by a professional engineer experienced in the design and construction of dams in order to detect any changes in condition; and (2) The following actions should be completed within one year from the date of approval of this report: The spillway discharge culvert should be properly repaired or replaced, Soil on the downstream side of the embankment should be properly compacted and stabilized, Trees and adverse vegetation on the embankment should be removed, and The owner of the dam should develop written operating procedures and a periodic maintenance plan to ensure the safety of the dam.
