National Dam Inspection Program. Dunmore Number 1 Dam (NDI ID Number PA-00364, DER ID Number 35-25), Susquehanna River Basin, Little Roaring Brook, Lackawanna County, Pennsylvania. Phase I Inspection Report,
Abstract
Based on visual inspection, available records, calculations and past operational performance, Dunmore No. 1 Dam is judged to be in good condition. The spillway can pass 84 percent of the Probable Maximum Flood (PMF) without overtopping of the dam. The spillway capacity is rated as inadequate. Two culverts, immediately downstream of the dam, may provide significant tailwater effects at the dam. If the top of the dam were raised 0.4 foot to its design elevation, the spillway can pass 90 percent of the PMF. The spillway capacity would still be rated as inadequate. Because there is no analysis available, the structural stability of the masonry gravity spillway is unknown. The spillway right training wall does not have any significant deviations from the guidelines for stability. There is no evidence of instability on the embankment.
