National Dam Inspection Program. Lake Jamie Dam (NDI ID Number PA-00778, DER ID Number 45-220). Delaware River Basin, Leavitt Branch of Brodhead Creek, Monroe County, Pennsylvania. Phase I Inspection Report,

Based on available records, visual inspection, calculations, and past operational performance, Lake Jamie Dam is judged to be in fair condition. The recommended Spillway Design Flood (SDF) for the size and hazard classification of the dam varies between the 1/2 Probable Maximum Flood (PMF) and the PMF. Based on the criteria and the downstream conditions, the selected SDF at the dam is the PMF. Based on existing conditions, the spillways will pass about 46 percent of the PMF before overtopping of the dam occurs. However, it is judged that the dam could just withstand the depth and duration of overtopping that would occur for the 1/2 PMF. If the low areas on the top of the embankment were filled to the design elevation, the spillways would pass about 77 percent of the PMF. For either condition, the spillway capacity is rated as inadequate, but not seriously inadequate. The steep downstream slope and the seepage at the dam indicate that the embankment stability may be marginal for the normal operating condition. The main spillway weir is judged to be stable. The ability of the emergency drawdown facility to function is uncertain. The dam has significant deviations from the design data. Maintenance at the dam needs to be improved. (Author)
