National Dam Inspection Program. Pomeroy Memorial Reservoir Dam (NDI ID Number PA-40 DER ID Number 8-2), Susquehanna River Basin, West Branch Sugar Creek, Bradford County, Pennsylvania. Phase I Inspection Report
The Pomeroy Memorial Reservoir Dam appears to be in poor condition and poorly maintained. The concrete on the upstream slope of the dam is in a deteriorated condition as is the concrete in the spillway section. The spillway retaining walls are visibly deteriorated and a section of the right spillway wingwall has cracked and fallen away from the structure. Maintenance of the dam and operating facilities is considered poor. The drainline valves have not been operated in the recent past. Pomeroy Memorial Reservoir Dam is a high hazard-small size dam. The recommended spillway design flood (SDF) for a dam of this size and classification is in the range of 1/2 PMF to PMF. Based on the downstream potential for loss of life, the spillway design flood has been selected as the PMF. The spillway and reservoir are capable of controlling approximately 9% of the PMF without overtopping the embankment low spot. If the low spot elevation were to be filled to an elevation consistent with the remaining portion of the embankment crest the spillway and reservoir would be capable of controlling approximately 20% of the PMF without overtopping the embankment. Based on criteria established by the Corps of Engineers, the spillway is termed inadequate.
