National Dam Inspection Program. Laurel Run Number 2 Dam. (NDI ID Number PA-00550, DER ID Number 40-23), Susquehanna River Basin, Laurel Run, Luzerne County, Pennsylvania. Phase I Inspection Report
Based on available records, visual inspection, calculations, and past operational performance, Laurel Run No. 2 Dam is judged to be in good condition. The spillway will pass about 7 percent of the Probable Maximum Flood (PMF) before overtopping of the dam occurs. The recommended Spillway Design Flood (SDF) for the size and hazard classification of the dam varies between the 1/2 PMF and the PMF. Based on the criteria and the downstream conditions, the SDF is the PMF. The spillway capacity is rated as inadequate. It is judged that the dam could withstand the depth and duration of overtopping that would occur for the PMF. Records show that the dam has withstood an overtopping of 7 feet. No stability problems were evident at the dam. Although there is significant leakage at the masonry joints in the dam, records show that the leakage has existed for at least 65 years without any detrimental effects on the dam. The leakage is judged not to be a hazard to the dam at present. The ability of the emergency drawdown valve to function is uncertain because it has not been operated recently.
