The dam and spillway appear to be in good condition and are adequately maintained. Tobyhanna Lake No. 2 Dam is a high hazard-intermediate size dam. The spillway design flood (SDF) for a dam of this size and classification is the PMF. The spillway and reservoir are capable of controlling approximately 58% of the PMF. Based on criteria established by the Corps of Engineers, the spillway is termed inadequate.
