National Dam Inspection Program. Curtis Dam (NDI ID Number PA-00370 DER ID Number 35-17), Susquehanna River Basin, White Oak Run, Lackawanna County, Pennsylvania. Phase I Inspection Report,
Abstract
Based on visual inspection, available records, calculations, past operational performance, and according to criteria established for these studies, Curtis Dam is judged to be unsafe, nonemergency, because the spillway capacity is rated as seriously inadequate. The existing spillway can pass 17 percent of the Probable Maximum Flood (PMF) without overtopping of the dam. The resulting outflows from the failure of Curtis Dam would probably overtop and cause the failure of Emlhurst Dam. This would result in the loss of life. As a whole, the dam is judged to be in fair condition. If the low areas of the top of the embankment were raised 1.1 feet to the design elevation and if the low areas of the dike were raised 2.0 feet to the design elevation, the spillway could pass 46 percent of the PMF. The spillway capacity would still be rated as seriously inadequate. There is no evidence of stability problems on the embankment. The spillway and auxiliary spillway sections meet the OCE guidelines for stability. A length of the left spillway training wall has failed.
