National Dam Inspection Program. Thorn Run Dam, NDI Number PA-271. Ohio River Basin, Thorn Creek, Butler County, Pennsylvania. Phase I Inspection Report.
Abstract
Periodic state inspection reports reveal the dam has been adequately maintained over the years. In fact, the majority of these reports state its general appearance to be good. The inspection reports, however, clearly document what appeared to be a steadily deteriorating condition relative to the concrete. Leaks at various locations along the spillway have also been ovbserved but apparently were never considered significant. In addition, minor settlement of the embankment crest near the spillway was also mentioned. Records indicate that consideration was given to the construction of a new facility around 1960. Subsurface investigations of the dam site and proposed borrow areas were performed, but construction was not undertaken. Thus the facility in existence today is virtually the same one constructed in 1903.
