Abstract
Lyman Run Dam is an earthfill dam 920 feet long and 50 feet high. The top width of the dam is 14 feet. The spillway is located at the left abutment of the dam and consists of a concrete lined chute. The weir consists of a 125 foot long concrete ogee. The inspection and review of data of Lyman Run Dam did not reveal any problems which require emergency action. The dam appears to be in good condition with the exception of the seepage, well maintained and safely operated. Lyman Run Dam is a high hazard-intermediate size dam. The Spillway Design Flood is the PMF(Probable Maximum Flood). The spillway and reservoir are capable of controlling the PMF. Based on criteria established by the Corps of Engineers, the spillway is termed adequate.
