National Dam Inspection Program. Camp Sinoquipe Lake Dam (NDI ID Number PA-1058, DER ID Number 29-29), Susquehanna River Basin, Plum Run, Fulton County, Pennsylvania. Phase I Inspection Report
Abstract
The assessment of the Camp Sinoquipe Lake Dam is based upon visual observations made at the time of inspection, review of available records and data, hydraulic and hydrologic computations and past operational performance. In general, the dam appears to be in fair condition. No major erosion was observed on the embankment crest or slopes during the inspection. The retaining wall located at the junction of the embankment and the spillway should be repaired due to undercutting caused by flows in the discharge channel. The condition of the reservoir drainline is questionable, based on a 1966 memorandum in the DER files which indicates the construction of the drainline deviated from the original design. Two seepage areas were observed during the inspection. One area was observed on the downstream slope in the area of the masonry retaining wall located at the junction of the embankment and spillway. The Camp Sinoquipe Lake Dam is a low hazard-small size dam. The recommended spillway design flood (SDF) for a dam of this size and classification is in the range of the 50-year storm to the 100-year storm. No homes were observed to exist in the potential downstream flood plain associated with a dam failure and no significant structures were observed in the flood plain. A township road exists approximately 1200 feet downstream of the dam and agricultural areas exist approximately one mile downstream of the dam. The spillway design flood has been selected as the 100-year storm. The visual observations, review of available data, hydrologic and hydraulic calculations and past operational performance indicate that the Camp Sinoquipe Lake Dam is capable of controlling the spillway design flood (100-year storm).
