National Dam Safety Program. Beatties Millpond Dam (Inventory Number VA 08535), York River Basin, Hanover County, Virginia. Phase I Inspection Report
Beatties Millpond Dam is an earthfill embankment approximately 13.9 feet high and 365 feet long with a 32 foot wide broad-crested concrete weir spillway located at the left abutment. The dam, located about 2.3 miles northeast of Old Cold Harbor, Virginia, is used for recreation. Beatties Millpond 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 good overall condition at the time of inspection. Maintenance of the dam is considered to be inadequate. A stability check of the dam 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 40 percent of the SDF or 8 percent of the PMF without overtopping the dam. A 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. However, overtopping flows from the SDF are considered detrimental to the earth embankment. Therefore, the spillway is adjudged as inadequate but not seriously inadequate.
