National Dam Safety Program. Wheatlands Dam (Inventory Number VA 06913), Potomac River Basin, Frederick County, Virginia. Phase I Inspection Report.
Abstract
Wheatlands Dam is an earthfill structure approximately 680 feet long and 71 feet high. The dam is owned by Mr. J. L. Bowman and F. L. Glaize of Stevens City, Virginia. The dam is classified as an intermediate size dam with a significant hazard classification. The principal spillway is a 72-inch corrugated metal pipe (CMP) serving as a drop-inlet that passes into a 60-inch CMP that passes through the dam at low level. The emergency spillway is an open channel earthen cut left of the left abutment. The reservoir was designed to provide 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 PMF. The spillways will pass 100 percent of the PMF or 100 percent of the SDF without overtopping the crest of the dam with normal pool established at the present condition. The spillways are adjudged as adequate. In 1978, the 72-inch CMP drop-inlet was damaged during an ice thaw draining the lake to its present lake level. A portion of the upstream slope eroded as part of that failure. The visual inspection revealed no problems that required immediate remedial measures. However, a professional engineering consultant should be retained to inspect the 60-inch CMP spillway.
