National Dam Inspection Program. Penn Lake Dam (NDI ID Number PA-00542, DER ID Number 40-28), Delaware River Basin, Wright Creek, Luzerne County, Pennsylvania. Phase I Inspection Report
Penn Lake Dam is an earth embankment approximately 350 feet long and 44 feet high at its maximum section. The spillway consists of twelve 42-inch diameter, 20-foot long pipes located approximately 1,000 feet left (looking downstream) of the dam. Earth swales on both sides of the battery of pipes function as auxiliary spillways. The 56 acre reservoir is used for recreation by members of the Penn Lake Association. Examination of the results of the hydrologic and hydraulic analyses indicates that the spillway (pipes and swales) is capable of passing 48 per cent of the Probable Maximum Flood (PMF) without overtopping of the embankment. Failure of the dam would increase the hazard of loss of life downstream of the dam. The capacity of the spillway system is therefore classified as 'Seriously Inadequate.' The dam is considered to be unsafe (non-emergency). Based on visual observations made during the date of the inspection, the dam is considered to be in poor condition.
