National Dam Inspection Program. Ironworks Dam, (ID Number Pa. 00789) Delaware River Basin, Ironworks Creek, Bucks County, Pennsylvania. Phase I Inspection Report
Ironworks Dam and Springfield Lake have been in continual service since 1944 and are owned by the Philadelphia Suburban Water Company. It has been classified as having a 'High' hazard potential. Based on the visual inspection, evaluation of the records, and past operational performance, the dam is judged to be in good condition. The dam was not designed to pass the probable maximum flood as required by the Federal (OCE) Guidelines, but it does pass 70 percent of the calculated PMF without overtopping. Therefore, the spillway is considered 'Inadequate'. If the parapet wall is reconstructed to accommodate additional storage, or if the emergency spillway is lowered one foot, this structure could pass the PMF and be upgraded to an 'Adequate' classification. The visual inspection of the dam and reservoir facilities detected no symptoms of uncontrolled seepage, instability, significant deterioration or other conditions that would suggest impending hazardous conditions. Some wet zones were noted downstream in addition to the development of woody vegetation on the downstream slope and emergency spillway. Some upstream riprap sloughing was noted.
