Summary
This public utility structure was completed in 1972 by Stone & Webster Engineering Corp. The dam stands at a height of 28 feet and has a storage capacity of 487,000 acre-feet, serving the primary purpose of water supply for the region.
Managed by the Federal Energy Regulatory Commission, Lake Anna Dam and Reservoir plays a crucial role in water resource management in the area. With a surface area of 13,000 acres and a low hazard potential, the dam ensures the efficient regulation of the North Anna River. Despite its age, the dam's condition assessment is not available, highlighting the need for regular inspections and risk management measures to ensure its continued safety and reliability.
For water resource and climate enthusiasts, Lake Anna Dam and Reservoir - Dike V presents an intriguing case study in infrastructure management and risk assessment. With its strategic location and significant storage capacity, this earth dam serves as a key component in the water supply network of Virginia. As discussions around climate change and water scarcity continue to gain prominence, understanding the role and resilience of structures like Lake Anna Dam becomes increasingly important for sustainable water resource management.

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.
