National Dam Inspection Program. Croops Dam (NDS I.D. Number PA 01063, DER I.D. Number 40-227), Susequehanna River Basin, Tributary to Hunlock Creek, Luzerne County, Pennsylvania. Phase I Inspection Report.
Abstract
Croops Dam is privately owned, and the reservoir is used for recreational purposes. The dam is currently in poor condition. In accordance with criteria established by Federal (OCE) Guidelines, the recommended spillway design flood for this 'Small' size dam and 'Significant' hazard classification is the 100 Year Flood to one-half the Probable Maximum Flood (PMF). Based on the small capacity of the reservoir and the fact that no loss of life is likely during failure of the structure, the 100 year event has been selected as the spillway design flood. Hydrologic and hydraulic computations presented in Appendix D indicate that the spillway structures are not capable of discharging the 100 year event without overtopping the embankment by about 1.18 feet for about 7.0 hours, assuming the spillways are not clogged. If the spillways are clogged by debris, the embankment is expected to be overtopped by 1.24 feet for greater than eight hours. The structure is considered to have an 'Inadequate' spillway as it will not pass the spillway design flood without overtopping the embankment. (Author)
