National Dam Safety Program. Lake Devolia Dam. (Inventory Number Va 03331), York River Basin, Caroline County, Commonwealth of Virginia. Phase I Inspection REport
Lake Devolia Dam is an earthfill embankment approximately 20.6 feet high and 460 feet long. The principal spillways consist of one 24-inch and one 36-inch diameter corrugated metal pipes (C.M.P.) which pass through the embankment at the right abutment and approximate center of the dam, respectively. The left and right emergency spillway areas are natural overflow areas and are adjacent to the left and right abutments of the dam. The dam is located in Caroline County, approximately 1.8 miles west of Ladysmith, Virginia. The dam is owned by the Lake Land'or Property Owner's Association and is used for recreation. Lake Devolia Dam is a 'small' size - 'significant' hazard structure as defined by the Recommended Guidelines for Safety Inspection of Dams. The dam and appurtenant structures were in poor condition at the time of the inspection. Using the Corps of Engineer's screening criteria for the initial review of spillway adequacy, the 1/2 Probable Maximum Flood (1/2 PMF) was selected as the spillway design Flood (SDF) for Lake Devolia Dam. The SDF was routed through the reservoir and found to overtop the dam by a maximum depth of 1.0 feet with an average critical velocity of 4.6 feet per second (f.p.s). Total duration of dam overtopping would be about 1.2 hours.
