National Dam Inspection Program. Keen Lake Dam (NDI Number PA-00092, Der Number 64-13), Delaware River Basin. 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. In accordance with the Corps of Engineer's evaluation guidelines, the size classification of this dam is intermediate and the hazard classification is high. The spillway capacity is inadequate for passing the PMF (Probable Maximum Flood) peak inflow without overtopping the dam. The project is capable of passing only 14 percent of the PMF. Failure of this dam will significantly increase the hazard to loss of life downstream from the dam. The spillway capacity is seriously inadequate. The project, therefore, is considered to be unsafe, nonemergency.
