National Dam Inspection Program. Shickshinny Lake Dam (NDS-ID Number PA-572, DER-ID Number 40-220), Susquehanna River Basin, Shickshinny Creek, Luzerne County, Pennsylvania. Phase I Inspection Report
Shickshinny Lake Dam is an earthfill dam, 365 feet long and 33 feet high. The crest width of the dam is 17 feet. The upstream slope is 3H:1V and the downstream slope is 2.5H:1V. Both the upstream and downstream slopes are grass covered. Some riprap exists on the upstream slope. The principal spillway consists of a reinforced concrete riser and a 30 inch reinforced concrete pipe which passes under the dam. The top of the riser unit is provided with an anti-vortex device. A gate valve is provided on an inlet pipe just inside the riser unit. Based on our hydraulic and hydrologic analysis it was determined that the spillway and reservoir are capable of controlling approximately 52% of the PMF. Based on criteria established by the Corps of Engineers, the spillway is termed inadequate. No major deficiencies were observed during the inspection. Seepage was noted at the left abutment contact and did not appear to be excessive. Erosion was observed at the outlet structure for the spillway and drainline.
