Summary
Owned by the local government, this dam serves the primary purpose of water supply and also contributes to flood risk reduction in the area. With a height of 37 feet and a length of 1600 feet, it has a storage capacity of 5313 acre-feet and covers a surface area of 187 acres.
Managed by the Department of Conservation and Recreation, South Anna Dam #22 is regulated by the state of Virginia and undergoes regular inspections to ensure its structural integrity. Despite being classified as having a high hazard potential, the dam's condition is reported as satisfactory as of the last assessment in December 2020. The dam plays a vital role in providing water to the local community and managing the flow of Northeast Creek, making it a key asset for both water resource and climate enthusiasts in the region.
With Congresswoman Abigail Davis Spanberger representing the area, South Anna Dam #22 stands as a critical piece of infrastructure that not only safeguards against flooding but also ensures a stable water supply for the residents of Louisa, Virginia. As the climate continues to shift, the importance of well-maintained dams like South Anna Dam #22 in mitigating water-related challenges becomes increasingly evident, making it a focal point for those interested in sustainable water resource management and climate adaptation strategies.

Dam Data Reference
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.
