National Dam Inspection Program. Boydstown Dam (NDI Number PA-00270 Penn DER Number 10-1), Ohio River Basin, Connoquenessing Creek, Butler County, Pennsylvania. Phase I Inspection Report
Boydstown Dam is a diaphragm earthfill embankment approximately 28 feet high (maximum) and 330 feet long. The spillway is located at the left abutment of the dam. It is uncontrolled, and the broad-crested weir is 60 feet long (perpendicular to flow). An analysis indicated that the spillway will pass only 30 percent of the required Probable Maximum Flood before overtopping will occur. As a result of this analysis and others, the spillway is considered 'seriously inadequate.' The overall condition of the dam was assessed to be very poor because the upper half of the spillway is in such a deteriorated condition that significant damage to the structure may occur if large flows were to pass through the spillway. In addition, several features of the dam do not meet current design standards; the 7 foot crest width, the lack of an internal drainage system, the absence of positive cut-offs along the outlet and water supply pipes, and the lack of information concerning the details and condition of the outlet works.
