Abstract:

Raven Run Dam No. 3 is an earth and rockfill dam 1,080 feet long and 40 feet high. The crest width of the dam varies from 10 feet wide to 24 feet wide. A secondary embankment Right Arm is located north of the main embankment. This embankment is 320 feet long and 7 feet high. The crest width is 8 feet. The spillway is located on the main embankment 780 feet from the left abutment. The spillway is rectangular shaped with stone masonry retaining walls forming the sides. The weir length is 40 feet long. The spillway discharges into a gully created by erosion and eventually flows into Raven Run No. 2 Reservoir. The inspection and review of data of Raven Run Dam No. 3 did not reveal any problems which require emergency action. The dam appears to be in fair condition but poorly maintained and operated. The spillway and reservoir are capable of controlling approximately 58 of the PMF. Based on criteria established by the Corps of Engineers, the spillway is termed inadequate.
