National Dam Inspection Program. Wanamie Dam (NDI ID Number PA-00552, DER ID Number 40-21), Susquehanna River Basin, Wanamie Run, Luzerne County, Pennsylvania. Phase I Inspection Report
Based on available records, visual inspection, calculations, past operational performance, and consideration of the existing normal pool level, Wanamie Dam is judged to be in fair condition. The existing spillway is a gorge that was eroded when the spillway washed out in 1955. The spillway can pass the Probable Maximum Flood (PMF), which is the Spillway Design Flood (SDF), with 7.9 feet of freeboard. Based on the size and hazard classification of the dam, the recommended SDF varies between the 1/2 PMF and the PMF. The selected SDF is based on the criteria and the downstream conditions. The pool level at maximum PMF level is 5.2 feet below the normal pool level that existed prior to 1955. The spillway capacity is rated as adequate. This rating is dependent upon removal of the remains of the timber structure in the spillway. The only significant stability problem that exists at the embankment is a bulge near the left abutment of the embankment. The owner presently has no intention of returning the dam to its design condition because there is no present requirement for increased water supply storage at the dam. There are no functional emergency drawdown facilities at the dam. Maintenance of the dam is inadequate.
