Bradford City No. 2 Dam is a diaphragm earthfill embankment dam with a maximum height of 44 feet and a crest length of 920 feet. Discharge is provided by an uncontrolled chute spillway located at the right abutment. The dam is owned and operated by the Bradford City Water Authority for water supply. The visual inspection and review of engineering data, performed in November 1978 through January 1979, indicate no serious deficiencies requiring emergency attention. The dam was found to be in fair overall condition at the time of inspection. However, the owner should immediately retain a qualified consultant for additional investigation of certain features. Hydraulichydrologic evaluations revealed that the spillway will not pass the Probable Maximum Flood PMF without overtopping the dam. Further, the spillway is considered inadequate because the spillway will pass approximately 38 percent of the PMF before overtopping and failure is not likely to occur under the 50 percent PMF condition.
