National Dam Inspection Program. Lower Birchwood Lake Dam (NDI ID Number PA-00403, DER ID Number 52-145). Delaware River Basin, Dike County, Pennsylvania. 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 Engineers' evaluation guidelines, the size classification of this dam is small and the hazard classification is high. These classifications indicate that the Spillway Design Flood (SDF) for this dam should be in the range of one-half the Probable Maximum Flood (PMF) to the full PMF. The recommended SDF for this dam is one-half of the PMF. Since the spillway discharge capacity and reservoir storage capacity are capable of passing 50% of a PMF without overtopping, the spillway is considered to be adequate.
