National Dam Safety Program. Upper Mohawk Lake Dam (NJ00292), Delaware River Basin, Tributary to Paulins Kill River, Sussex County, New Jersey. Phase I Inspection Report.
Abstract
Based on available records, past operational performance, visual inspections and Phase I engineering analysis, Upper Mohawk Lake Dam is asessed as being in good overall condition. Based on investigations of the downstream flood plain made in connection with this report, it is recommended that the hazard potential classification be downgraded from high to significant hazard. The spillway is capable of passing the designated spillway design flood (100-year storm) without an overtopping of the dam and, therefore, is assessed ass being adequate. It is recommended that the following remedial measures be undertaken by the owner in the future: (1) The trash rack at the downstream end of the spillway discharge flume should be reinforced or replaced, and (2) Some trees on the embankment appeared to have been planted for aesthetic purposes while others appeared to be randomly located. Therefore, trees on the embankment should be investigated to assess their detrimental effect on the dam and those found to be adverse should be removed.
