National Dam Inspection Program. Mahanoy Township Dam Number 2. (NDS ID Number PA-685, DER ID Number 54-34) Mahanoy Township Municipal Authority. Susquehanna River Basin, Cold Run, Schuylkill County, Pennsylvania. Phase I Inspection Report.
Abstract
The assessment of Mahanoy Township Dam No. 2 is based upon visual observations made at the time of inspection, review of available records and data, hydraulic and hydrologic computations and past operational performance. Mahanoy Township Dam No. 2 is a high hazard-small size dam. The spillway design flood (SDF) for this dam is the 1/2 PMF to PMF. Based on the downstream potential for loss of life the SDF is the PMF. The spillway and reservoir are capable of controlling approximately 73% of the PMF without overtopping the embankment. Based on criteria established by the Corps of Engineers, the spillway is termed inadequate. No seepage or wet areas were observed during the inspection on the abutments, slopes nor along the toe of dam.
