National Dam Inspection Program. Lake Montrose Dam, (NDI ID Number PA-00047 DER ID Number 58-20). Susquehanna River Basin. Snake Creek, Susquehanna County, Pennsylvania. Phase I Inspection Report
Based on visual inspection (18 July 1979), available records, calculations, past operational performance, and according to criteria established for these studies, Lake Montrose Dam is judged to be unsafe, nonemergency, because the spillway capacity is rated as seriously inadequate. The existing spillway can pass only 17% of the Probable Maximum Flood (PMF) without overtopping of the dam. Based on the type of construction and the condition of the dam, it is judged that the dam could not withstand the depth and duration of overtopping that would occur for the PMF or the 1/2 PMF. Failure of the dam would cause an increased hazard to loss of life downstream. As a whole, the dam is judged to be in poor condition. The spillway has undergone a gradual structural failure that has resulted in a reduction of spillway capacity. Continuation of the gradual failure, or perhaps a sudden failure, appears to be possible. There are no functional outlet works for the dam. Maintenance of the project is inadequate. There is no program for regular inspection of the dam.
