Summary
Designed by the Virginia Department of Conservation and Recreation, this earth dam stands at a height of 33 feet and serves the primary purpose of flood risk reduction along Fielding Creek. With a storage capacity of 990 acre-feet and a normal storage of 130 acre-feet, the dam covers a surface area of 25 acres and drains a watershed area of 2.85 square miles.
Despite its high hazard potential, South Anna Dam #3 is currently assessed to be in fair condition as of the last inspection in April 2020. The dam has not undergone any modifications since its completion, and it is regulated, permitted, inspected, and enforced by the Virginia Department of Conservation and Recreation. The emergency action plan for the dam was last revised in December 2018, and the structure meets state guidelines for emergency preparedness. With a close proximity to residential areas, this dam plays a crucial role in mitigating flood risks and protecting the surrounding community from potential disasters.

Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
