National Dam Inspection Program. Heilman Dam (NDI Number PA-00612, DER Number 13-005), Delaware River Basin, Carbon County, Pennsylvania. Phase I Inspection Report
Based on the visual inspection, past performance and the available engineering data, the dam and its appurtenant structures appear to be in poor condition. In accordance with the Corps of Engineers' evaluation guidelines, the size classification of this dam is small and the hazard classification is significant. These classifications indicate that the Spillway Design Flood (SDF) should be in the range of the 100 year flood to one-half the Probable Maximum Flood (PMF). The recommended SDF for this structure is the 100 year flood. The spillway capacity is not adequate for passing the SDF peak inflow without overtopping the dam. The spillway is considered to be inadequate, but not seriously inadequate. Some recommendations presented for immediate action by the owner are: (1) that measures shall be taken to provide an adequate spillway capacity, which shall include the raising of the embankment profile to at least the design crest elevation, (2) that the embankment be cleared of all trees, brush and weeds under the direction of a professional engineer, experienced in the design and construction of earthfill dams, and (3) that access above the floodplain be provided for surveillance.
