National Dam Inspection Program. Kennametal Reservoir Dam. (NDI Number PA-00482, Penn DER-Number 65-120) Ohio River Basin, Miller Run, Westmoreland County, Pennsylvania, Phase I Inspection Report,
Abstract
Based on a review of available design information and visual observations of conditions as they existed on the date of the field inspections, the general condition of the Kennametal Reservoir Dam is considered to be good. The structure is classified as a 'small' size, 'high' hazard dam. Corps of Engineers guidelines recommend 1/2 to one times the Probable Maximum Flood (PMF) for ('small' size, 'high' hazard dams. Kennametal Reservoir Dam's Spillway Design Flood is 1/2 the Probable Maximum Flood (PMF). Spillway capacity is 'inadequate' because the non-overtopping flood discharge capacity, was estimated using the HEC-1 computer program, was found to be 13 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 of life downstream. The visual inspection indicated minor deficiencies which are considered correctable.
