National Dam Safety Program. Elon Water Works Dam (Inventory Number VA 00908), James River Basin. Amherst County, Virginia. Phase I Inspection Report
The Elon Water Works Dam is a zoned earth fill dam approximately 52.1 feet high and 490 feet long. The dam is classified as an intermediate size dam with a significant hazard classification. The emergency spillway is an earthen channel with a trapezoidal cross section at the left abutment. The principal spillway is a concrete drop-inlet with a fixed crest elevation of 663 feet. The reservoir is used for water supply. Based on criteria established by the Department of the Army, Office of the Chief of Engineers (OCE), the Spillway Design Flood (SDF) is the 1/2 PMF. The emergency spillway will pass 32 percent of the PMF or 64 percent of the SDF without overtopping the dam. The SDF will overtop the dam by a maximum of 1.2 feet, reach an average critical velocity of 5.1 feet per second and flow over the dam for 2.4 hours. The emergency spillway is adjudged inadequate, but not seriously inadequate.
