National Dam Inspection Program. Middle Dam (NDI-ID-PA-00256) (DER-ID-45-3) Delaware River Basin, Sambo Creek, Monroe County, Borough of East Stroudsburg. Phase I Inspection Report.

Based on visual inspection, available records, calculations, past operational performance, and according to criteria established for these studies, Middle Dam is judged to be unsafe, non-emergency because the spillway capacity is rated as seriously inadequate. Under existing conditions, the spillway can pass only about 22 percent of the Probable Maximum Flood PMF without overtopping of the dam. If low areas on the top of the dam were filled to the design elevation for the top of the dam, the spillway would pass about 33 percent of the PMF. For either condition, it is judged that the dam could not withstand the depth and duration of overtopping that would occur for the 12 PMF. Failure of the dam would cause an increased hazard for loss of life downstream. As a whole, the dam is judged to be in fair condition.
