National Dam Safety Program. Upper Wallace Dam, (Inventory Number VA 01516), Potomac River Basin, Augusta County, Virginia. Phase I Inspection Report.
Abstract
Upper Wallace Dam is a homogeneous earthfill structure about 325 ft long and 40 ft high. The principal spillway consists of a rectangular concrete riser and an outlet pipe which extends through the structure. The top of the dam serves as an access road to the Owner's residence with a 10 ft wide gravel surface. An earth emergency spillway is located at the right abutment with a 70 ft wide bottom and 2H:1V side slopes. The dam is located on Poor Creek approximately one mile east of Greenville, Virginia. The lake is for recreational purposes and is owned and maintained by Mr. Gregory Chandler. Based on criteria established by the Department of the Army, Office of the Chief of Engineers (OCE), the appropriate Spillway Design Flood (SDF) is the 1/2 PMF. The spillway will pass 80 percent of the Probable Maximum Flood (PMF) or 160 percent of the SDF. The spillway is judged adequate. An evaluation of the stability condition could not be made since there is no design or construction data for this structure.
