Abstract:

Camp Delmont Dam is a concrete capped rockfilled timber crib structure with steel and timber sheetpile abutments about 190 feet long, with a maximum height of 19 feet. The dam has a maximum storage capacity of 236 acre feet and a maximum height of 19 feet which places it in the Small size category. Because of the chance for appreciable damage to several cottages located downstream of the site and little chance for loss of life due to failure of the dam, the dam is judged to be a Significant hazard structure. Due to the inhabitable dwellings located downstream of the dam, fifty percent of the Probable Maximum Flood PMF was selected as the appropriate Spillway Design Flood SDF. An examination of the results of the hydrologic and hydraulic analyses indicates that the spillway and adjacent roadway are capable of passing 36 of the PMF without overtopping the dam abutments. The selected SDF for the dam is fifty percent of the PMF. Since the spillway is not capable of passing the SDF, the spillway is classified as Inadequate. Further examination of the hydrologic and hydraulic analyses indicates that the spillway and adjacent roadway are capable of passing the 100 year event without overtopping the dam abutments. Based on visual observations and a review of the information obtained from Pennsylvania Department of Environmental Resources, Camp Delmont Dam appears to be in good condition.
