National Dam Inspection Program. Newtown Dam (NDS I.D. Number PA 01604, DER I.D. Number 9-178, SCS PA 621), Delaware River Basin, Newtown Creek, Bucks County, Pennsylvania. Phase I Inspection Report
Newtown Dam is owned by the Neshaminy Water Resources Authority and maintained by Bucks County. The dam and reservoir are used as a flood control structure for the downstream town of Newtown, Pennsylvania. The impoundment was designed by the United States Department of Agriculture, Soil Conservation Service, in 1976-77 and the structure was officially completed in 1980. The dam and its appurtenant facilities are considered to be in good condition. The dam is classified as an 'Intermediate' size structure with a 'High' hazard classification, consistent with its potential in the event of failure for extensive property damage and loss of life downstream of the dam and in Chalfont, Pennsylvania. In accordance with criteria established by Federal (OCE) Guidelines, the recommended spillway design flood for this 'Intermediate' size dam and 'High' hazard classification is the Probable Maximum Flood (PMF). The Soil Conservation Service designed this dam as a Class C structure, which requires that the spillway systems be designed to pass the PMF. The hydrologic and hydraulic computations presented in Appendix D indicate that the spillway structures are capable of discharging the PMF without overtopping the embankment. Therefore, the structure is considered to have an 'Adequate' spillway system.
