National Dam Safety Program. Ward Run. NDI Number PA-01124 PennDER Number 63-75 SCS Number PA-483. Ohio River Basin, Washington County, Pennsylvania. Phase I Inspection Report,
Abstract
PA 483 is a 74-foot high, zoned-earthfill floodwater retarding dam designed by the U.S. Department of Agriculture, Soil Conservation Service (SCS). The dam is owned and operated by the Washington County Commissioners. The dam consists of a 360 foot long embankment, a vegetated earth side channel emergency spillway, and an intake riser and outlet conduit (principal spillway). The dam and appurtenant structures were found to be in good overall condition at the time of the inspection. Hydraulic/hydrologic evaluations revealed that the spillway will pass the Probable Maximum Flood (PMF) without overtopping the dam. PA 483 is a 'High' hazard, 'Intermediate' size dam requiring evaluation for a spillway design flood (SDF) equal to the PMF. Therefore, the spillway is assessed as 'adequate.' The inspection revealed certain items of remedial work which should be performed immediately by the owner.
