National Dam Safety Program. Crystal Lake Dam (NJ00299), Delaware River Basin, Tributary to Delaware River, Burlington County, New Jersey. Phase I Inspection Report.
Abstract
Based on visual inspection, available records, calculations and past operational performance, Crystal 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 adequacy of the structure, several actions are recommended. The following actions should be initiated within six months from the date of approval of this report: (1) The outlet works should be investigated with respect to operational adequacy and, if necessary, restored to proper operational condition; (2) Rusted CMP surface drain pipe should be replaced by proper inlet and pipe; (3) Erosion of the embankment adjacent to the upstream wingwalls of the bridge should be properly stabilized; (4) Deteriorating riprap on the upstream and downstream faces of embankment should be repaired where necessary; and (5) All trees and adverse vegetation on the embankment should be removed.
