National Dam Safety Program. Salisbury Lake Dam (Inventory Number VA 04136), James River Basin. Chester County, Commonwealth of Virginia. Phase I Inspection Report
Salisbury Lake Dam is an earthfill embankment with a compacted clay core, approximately 1020 feet long and 37.3 feet high. The Dam is situated on Falling Creek, approximately 1.0 miles north of Midlothian, Virginia, and is used for recreational purposes by the owner, the Salisbury Lake Property Owners Association. Salisbury Lake Dam is a 'small' size - 'high' hazard structure as defined by the Recommended Guidelines for Safety Inspection of Dams. Deficiencies found during the field inspection and office analyses will require remedial treatment. A stability check is not required. Using the Corps of Engineers' screening criteria for initial review of spillway adequacy, the PMF was selected as the SDF for the 'small' size - 'high' hazard classification of Salisbury Lake Dam. The dam would be overtopped by the SDF, and the depth, duration, and rate of overtopping flows are considered detrimental to the embankment. The spillways are capable of passing only 30 percent of the PMF. The spillway is adjudged as seriously inadequate, since dam failure from overtopping would significantly increase the hazard to loss of life downstream from the dam over that which would exist just before overtopping failure.
