National Dam Safety Program. Crum Creek Dam (NDI-PA-00350, PA-DER-23-20), Delaware River Basin, Crum Creek, Delaware County, Pennsylvania. Phase I Inspection Report
Crum Creek Dam is a masonry gravity structure (cyclopean concrete) about 610 feet long and 25 feet high. A 210-foot long ungated overflow spillway is located along the length of the dam about 80 feet from the right abutment. The dam, which is classified as 'High' hazard, has a Spillway Design Flood (SDF) equal to the Probable Maximum Flood (PMF). A review of the results of the hydrologic and hydraulic analyses indicates that the spillway is capable of passing about 23 percent of the PMF. The spillway is classified as 'Inadequate' for passing the PMF; however, the spillway is not considered 'Seriously Inadequate' since the hazard potential due to a failure of the dam is not significantly greater than the hazard without a failure of the dam. Stability analyses were performed for both the overflow and non-overflow sections for the anticipated range of loading conditions. A review of the results indicates that the resultant of forces is located outside the middle third of the base width for 50 percent of the PMF, PMF and normal pool with ice loading conditions. Based on visual observations, review of the information provided by the Pennsylvania Department of Environmental Resources (DER), Division of Dam Safety, and conversations with the Owner's representative, Crum Creek Dam appears to be in good condition.
