Delaware River Basin Lakeville Creek Wayne County Pennsylvania Locklin Pond Dam Ndi Id Nopa 00139 Der Id No64 31 Clifton And Lewis Locklin Phase 1 Inspection Report National Dam Inspection Program

Based on available records, visual inspection, calculations, and past operational performance, Locklin Pond Dam is judged to be in good condition. Based on the size and hazard classification of the dam, the recommended SDF at the dam varies between the 100-year flood and the 1.2 PMF. Based on the criteria, the selected SDF is the 1.2 PMF. Based on existing conditions, the spillway will pass about 8 percent of the PMF before overtopping of the dam occurs. No stability problems are evident at the dam. There are no emergency drawdown facilities at the dam. Maintenance at the dam needs to be improved.

Based on available records, visual inspection, calculations, and past operational performance, Craft Pond Dam is judged to be unsafe, nonemergency, because the spillway capacity is rated as seriously inadequate. The recommended Spillway Design Flood (SDF) for the size and hazard classification of the dam varies between 1/2 of the Probable Maximum Flood (PMF) and the PMF. The selected SDF is the 1/2 PMF. The existing spillway will pass only about 23 percent of the Probable Maximum Flood (PMF) before overtopping of the dam occurs. It is judged that the dam could not withstand the depth and duration of overtopping that would occur for the 1/2 PMF. Failure of the dam would cause an increased hazard for loss of life downstream. Overall, the dam is in good condition. The maintenance of the dam is considered to be good; only a few minor maintenance deficiencies were observed. The other deficiencies observed were low spillway walls and an inoperable outlet works.
