National Dam Safety Program. Laurel Creek Dam (Inventory number VA 07704), New River Basin, Grayson County, Virginia. Phase I Inspection Report
Laurel Creek Dam is an earthen structure about 250 feet long and 17.5 feet high. The dam is classified as a small dam with a significant hazard classification. The principal spillway is a 30-inch corrugated metal pipe (CMP) drop-inlet with a 36-inch CMP control at normal pool. The emergency spillway is an open channel cut in the left abutment. The reservoir is used for recreation. Based on criteria established by the Department of the Army, Office of the Chief of Engineers (OCE), the Spillway Design Flood (SDF) is the 100 Year Flood. The spillway will pass 9 percent of the PMF or 19 percent of the SDF without overtopping the crest of the dam. The SDF will overtop the dam by about 1 foot, flow over the dam about 4 hours and reach a maximum velocity of 4.6 feet per second. Overtopping velocities are not considered detrimental to the dam. The spillway is adjudged as inadequate but not seriously inadequate.
