National Dam Safety Program. Fleming Dam (Inventory Number VA 04904), James River Basin, Cumberland County, Commonwealth of Virginia. Phase I Inspection Report.
Abstract
Fleming Dam is an earthfill embankment 29.4 feet high and approximately 423 feet long. The principal spillway consists of a 36 inch diameter corrugated metal pipe (CMP) riser connected to a 24 inch diameter CMP outlet. The emergency spillway is a 50 foot wide vegetated earth channel adjacent to the right abutment. The dam, located on Maxey Mill Creek approximately 3.7 miles northeast of Cumberland, Virginia, is used for recreation and as a stock pond. The dam is owned by Mr. John T. Clayton of Cumberland, Virginia. Fleming Dam is a 'small' size - 'significant' hazard structure as defined by the Recommended Guidelines for Safety Inspection of Dams. Visual inspection and office analyses indicate deficiencies requiring further investigation and remedial treatment. A stability check is not required. Using the Corps of Engineers' screening criteria for initial review of spillway adequacy, the 100-year flood was selected as the spillway design flood (SDF). The spillway is capable of passing up to 45 percent of the SDF or 8 percent of the PMF without overtopping the dam. Overtopping flows during the SDF are not considered detrimental to the embankment. The spillway is adjudged as inadequate. The spillway is not adjudged as seriously inadequate since dam failure from overtopping would not significantly increase the hazard to loss of life downstream from the dam over that which would exist just before overtopping failure.
