Summary
This earth dam stands at a height of 18 feet and serves primarily for recreational purposes, with a storage capacity of 66 acre-feet in its reservoir. Situated along a tributary of the North Anna River, the dam's hazard potential is currently undetermined, with its condition yet to be rated.
Despite lacking certain details such as completion year and condition assessment, Little Anna Dam remains a vital asset for water resource and climate enthusiasts in Virginia. Its presence not only offers recreational opportunities but also contributes to the overall water management and conservation efforts in the region. With state regulation, inspection, and enforcement in place, the dam ensures the safety and sustainability of its surrounding ecosystem.
As a part of the Baltimore District, Little Anna Dam adds to the network of water infrastructure in the area, providing not only recreational benefits but also potentially aiding in flood control and water supply management. While more information is needed to fully assess its risk and condition, the dam stands as a significant feature in the local water resource landscape, inviting further exploration and study for enthusiasts interested in the intersection of water management and climate resilience.

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.
