National Dam Inspection Program. Lost Creek Dam McKeesport Y.M.C.A. (NDI ID Number PA-739 PennDer Number 56-83), Ohio River Basin, Lost Creek, Somerset County, Pennsylvania. Phase I Inspection Report

摘要

Lost Creek Dam is classified as a 'small' size, 'significant' hazard dam in accordance with U. S. Army Corps of Engineers dam safety criteria. Based on the evaluation of available design information and visual observations of conditions as they existed on the dates of the field reconnaissances, the general condition of Lost Creek Dam is considered to be good. Wet zones, observed located at the downstream embankment toe, are believed attributable to surface runoff, and are not considered significant relative to dam stability at the present time. However, seepage emanating along the reservoir drain pipe outlet may represent a potential hazard to the dam. The cause and origin of this seepage could not be conclusively established by visual observation and review of construction documents. Therefore, periodic monitoring of the seep is recommended.
