National Dam Inspection Program. Fairchance Reservoir Dam. (NDI Number PA-00208, PennDER Number 26-70) Ohio River Basin. Fayette County, Commonwealth of Pennsylvania. Phase I. Inspection Report
Based on a review of available design information and visual observations of conditions as they existed on the date of the field inspection, the general condition of the Fairchance Reservoir Dam is considered to be fair. This classification id based on: (1) The visual observation of the seeps in the pond drain discharge channel; (2) The presence of growing and fallen trees on the embankment slope; (3) Outlet works pipes through the embankment that have no positive upstream flow controls; and (4) An inadequate spillway capacity. The structure is classified as a small size, high hazard dam for which the Corps of Engineers guidelines require a Spillway Design Flood (SDF). For the observed downstream conditions the Fairchance Reservoir Dam SDF is one half the Probable Maximum Flood (PMF). Spillway capacity is inadequate because the non-over-topping flood discharge capacity, as estimated using the HEC-1 computer program was found to be 4 percent of the PMF. The spillway is not seriously inadequate because failure of the structure would not significantly increase the flood stage and risk of loss life downstream.
