National Dam Inspection Program. Hopewell Dam (NDS I.D. Number PA 00724, DER I.D. Number 6-401), Delaware River Basin, Scotts Run, Berks County, Pennsylvania. Phase I Inspection Report,
Abstract
Hopewell Dam is a recreational structure located in French Creek State Park and owned by the Commonwealth of Pennsylvania. Visual inspection and review of the design and construction documentation indicate that the dam and appurtenant structures of Hopewell Dam are in good condition, although the condition of the dormant vegetation appeared to be fair at the time of the inspection. In accordance with criteria established by Federal (OCE) Guidelines, the spillway design flood for this Small size dam and High hazard classification is one-half to the full Probable Maximum Flood (PMF). As the dam's total capacity is near the upper limit of the size classification and Hopewell village is located at a narrow section of the floodplain, the selected spillway design flood is the full PMF. Hydrologic and hydraulic computations presented in Appendix D indicate the spillway is capable of passing approximately 33 percent of the PMF without overtopping the embankment. as the one-half PMF is estimated to cause failure of the structure and to significantly increase the potential for downstream damage, the spillway system of this structure is considered to be Seriously Inadequate and the dam is in an unsafe, nonemergency condition.
