Abstract:

The assessment of W.H. Walker Dam is based upon visual observations made at the time of inspection, review of available records and data, hydrologic and hydraulic computations, and past operational performance. W.H. Walker Dam, Mountain Lake Reservoir, consits of an earthfill dam with a concrete corewall. The dam is 500 feet long and 21 feet high from the downstream toe. The downstream slope is approximately 2H1V and the upstream slope 1.5H1V. The upstream slope has riprap protection. The crest is approximately 12 feet wide and forms an access road to the spillway. The spillway is a 175 feet long concrete gravity overflow section located at the right abutment. An abandoned powerhouse is located between the earth embankment section and the concrete spillway. The outlet works consists of a 30 inch pipe. The dam is located on the West Branch Conocoheague Creek, approximately one half mile southeast of Fannettsburg, Pennsylvania.
