The Warner Gap Hollow Dam, known locally as Edgemont Reservoir, consists of a zoned earth fill embankment approximately 65 feet high and 700 feet long. A puddle wall approximately 5 feet wide by 15 feet deep near the upstream toe is detailed on the design plans. The rip-rap covered slopes rise at 1 12H1V downstream and 2H1V upstream. The spillway is a rectangular concrete channel with the entrance located near the right abutment and discharging approximately parallel to the longitudinal axis of the embankment. The spillway crest is at elevation 901.0, approximately 4 feet below the dam crest.
