National Dam Inspection Program. Fishpond Dam (NDS ID Number PA-899, DER ID Number 19-81), Susquehanna River Basin, Unnamed Tributary to Roaring Creek, Columbia County, Pennsylvania. Phase I Inspection Report.
Abstract
The assessment of Fishpond 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. The inspection and review of data of Fishpond Dam did not reveal any problem which requires emergency action. The dam appears to be in poor condition mainly because of extensive seepage which appears to be increasing. A monitoring program developed by a professional engineer knowledgeable in earth dams should be implemented immediately. Fishpond Dam is a high hazard-small size dam. The SDF for a dam of this size and classification is 1/2 PMF to PMF. Based on the downstream potential for loss of life and property damage the spillway design flood has been selected as the PMF (Probable Maximum Flood). The spillway and reservoir are capable of controlling the PMF. Based on criteria established by the Corps of Engineers, the spillway is termed adequate. (Author)
