National Dam Inspection Program. Lake Jo-Ann Dam (Bracco Dam) (NDI Number PA 00504, PennDER Number 63-60), Ohio River basin, Branch of Peters Creek, Washington County, Pennsylvania. Phase I Inspection Report,
Abstract
Lake Jo-Ann Dam, formerly known as Bracco Dam, is classified as a 'High' hazard - 'Small' size dam. The dam and reservoir, owned by Mr. Daniel Carapellucci, Sr., are used for recreational purposes. The dam was found to be in fair overall condition at the time of the inspection. Hydraulic/hydrologic evaluations, performed in accordance with procedures established by the Baltimore District, Corps of Engineers, for Phase I Inspection Reports, revealed that the spillway will pass 27.5 percent of the Probable Maximum Flood (PMF) before overtopping of the dam occurs. A spillway design flood (SDF) in the range of the 1/2 Probable Maximum Flood (1/2 PMF) to the PMF is required for Lake Jo-Ann Dam. Because the dam is on the low end of the 'Small' size category, the 1/2 PMF was selected as the SDF. It was determined that during the 1/2 PMF the embankment would be overtopped by a maximum depth of 0.89 foot and a total duration of 5.00 hours. Because a limiting criteria of one foot or greater of overtopping and duration in excess of 2 hours was estimated for this dam, it was concluded that a dam failure during the 1/2 PMF is unlikely to occur.
