National Dam Inspection Program. Upper Owl Creek Dam (NDS-PA-00673, DER-54-96), Delaware River Basin, Schuylkill County, Pennsylvania. Phase I Inspection Report.
Abstract
Upper Owl Creek Dam is an earthfill embankment with a concrete core wall located on the centerline of the dam. The 9-inch thick concrete core wall is founded on rock over most of its length. The left end of this wall is founded on sandy clay. The embankment has a length of approximately 1300 feet with a maximum fill height of 38 feet. The spillway is located in the right abutment and has a crest length of 50 feet at approximately 4 feet below the top of dam. Based on the visual inspection, past performance and the available engineering data, the dam and its appurtenant structures appear to be in fair condition. In accordance with the Corps of Engineers' evaluation guidelines, the spillway capacity is inadequate to pass the PMF (Probable Maximum Flood) peak inflow without overtopping the dam. The project is capable of passing 45 percent of the PMF without overtopping.
