National Dam Inspection Program. Virgin Run Dam (NDS I.D. Number PA-00196, PennDer I.D. Number 26-85), Ohio River Basin, Virgin Run, Fayette County, Pennsylvania. Phase I Inspection Report,
Abstract
Base on a visual inspection, operational history, and available engineering data, the dam is considered to be in fair 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 is the Probable Maximum Flood (PMF). Results of the hydrologic and hydraulic analysis indicate the facility will pass and/or store about 62 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 heavy overgrowth across the downstream toe, a questionable structural and foundation design associated with the spillway, and an inadequate emergency warning system.
