National Dam Inspection Program. Reservation Dam, (NDI Number PA-00014, Pennder Number 38-78) Susquehanna River Basin, Indiantown Run, Lebanon County, Pennsylvania. Phase I Inspection Report
Based on a visual inspection, operational history, and available engineering data, the dam is considered to be in good condition. The size classification of the facility is small and its hazard classification is considered to be high. In accordance with the recommended guidelines, the Spillway Design Flood (SDF) for the facility ranges between the 1/2 PMF (Probable Maximum Flood) and the PMF. Due to the high potential for damage to downstream structures and possibly loss of life, the SDF is considered to be the PMF. Results of the hydrologic and hydraulic analysis indicate the facility will pass and/or store about 77 percent of the PMF prior to embankment overtopping. Consequently the spillway is assessed as being inadequate, but not seriously inadequate. Deficiencies noted by the inspection team included the following: (1) large trees rooted within the downstream embankment face; (2) a damaged and inadequate spillway discharge channel; and (3) a bent gate stem and partially obstructed outlet associated with the blowoff conduit.
