National Dam Inspection Program. Sunrise Lake Dam (NDI ID Number PA-00556 DER ID Number 40-216), Delaware River Basin, Pine Creek, Luzerne County, Pennsylvania. Phase I Inspection Report,

Sunrise Lake Dam is a homogeneous earthfill embankment 478 feet long and 27 feet high at its maximum section. The embankment has a curved alignment. A concrete chute spillway is located near the right abutment of the top of the. The approach channel is the reservoir area. The ogee crest is 105 feet long and 7.25 feet lower than the design elevation of the dam. Based on visual inspection, available records, calculations, past operational performance, and according to criteria established for these studies, Sunrise Lake Dam is judged to be in good condition. The spillway capacity is rated as adequate. The spillway can pass the Probable Maximum Flood (PMF) without overtopping of the dam. The headwall at the conduit outlet is tilted and is considered to be unsatisfactory. In the absence of stability computations showing that an adequate factor of safety exists, the downstream slope is considered to have a marginal factor of safety because of the steepness of the slope.
