National Dam Inspection Program. Placid Lake Dam, (NDS I.D Number PA 00616, DER I.D. Number 13-97), Delaware River Basin, Laurel Run, Carbon County, Pennsylvania. Phase I Inspection Report,

Abstract

Placid Lake Dam is owned by the Holiday Pocono Civic Association, Inc. The dam and reservoir are used for recreational purposes. The dam was built as part of a residential community and was completed in 1963. Visual inspection indicates that the spillway system of Placid Lake Dam is in fair condition. It is recommended that the following measures be undertaken immediately. (1) A detailed hydrologic/hydraulic investigation should be performed to determine the best method of increasing the spillway capacity. (2) The flashboard structure should be permanently removed from the top of the spillway drop inlet. (3) An investigation should be made into the actual cause of the apparent piping voids in the vicinity of the inlet conduit. (4) The spillway conduit joints should be sealed and the two downstream pipe lengths should be monitored for possible horizontal movement. (5) Erosion of the upstream face should be halted and the damaged embankment repaired. (6) The inlet sluice gate and the resevoir drain gate valve should be lubricated and exercised on a regular basis to insure their operational status. (7) All trees and brush should be removed from the downstram embankment face, the embankment returned to its original condition, and measures taken to establish a good stand of vegetation. (8) The rock dam in the diversion channel should be removed.
