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. Hydraulichydrologic 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.
