National Dam Inspection Program. Crescent Lake Dam (NDI-ID Number PA-00413, DER-ID 52-142) Delaware River Basin, Pike County, Pennsylvania. Phase I Inspection Report.
Abstract
Based on the visual inspection, past performance and the available engineering data, the dam and its appurtenant structures appear to be in fair condition. The following recommendations are presented for immediate action by the owner: (1) that the area at both ends of the spillway weir be cleared to a depth of at least 1.5 feet below the top of weir in order to increase the discharge capacity of the structure, (2) that the valve on the outlet pipe be maintained and operated at least once a year, (3) that all brush and high weeds be removed from the embankment on an annual basis, (4) that a formal surveillance plan and downstream warning system be developed for use during periods of high or prolonged rainfall, and (5) that an operation and maintenance manual be prepared for guidance in the operation of the dam during normal and emergency conditions, and that a schedule be developed for the annual inspection of the dam and its appurtenant structures.
