The dam at Bog Meadow Reservoir is an earth embankment approximately 280 feet long, 17 feet high with an average crest width of 30 feet. A stone masonry uncontrolled spillway is located at the right abutment of the dam. The outlet works is llocated near the left abutment and consists of a reinforced concrete intake structure, two 24- inch diameter conduits through the dam, and a gated outlet below the embankment. As a result of the visual inspection and the review of limited available data regarding this facility, the dam is considered to be in POOR condition. To assure the long term performance of this structure, several, items of concern require attention the apparent seepage along the downstream toe of the dam, the eroded and worn embankment slopes and crest, the deteriorated spillway stonework, the overgrowth of brush and small trees, and the sloughing of the stone armor protection on the upstream slope of the dam. The maximum capacity of the spillway, under a stillwater condition is equal to 819 CFS and represents more than 100 percent of the test flood outflow, under stillwater conditions, will produce a reservoir pool water level that has a freeboard allowance of only 0.20 feet below the top of the dam.
