Summary
Standing at a height of 65.5 feet, this earth dam serves primarily for recreational purposes, providing a storage capacity of 14,160 acre-feet of water. With a normal storage level of 9,880 acre-feet and a drainage area of 7.2 square miles, the dam covers a surface area of 500 acres, making it an essential feature for water resource management in the region.
Managed by the Department of Conservation and Recreation in Virginia, Lake of The Woods Dam has a high hazard potential but is currently assessed to be in satisfactory condition as of the last inspection in December 2017. The dam has a designated emergency action plan in place, with regular inspections to ensure its safety and compliance with state regulations. Despite its private ownership, the dam plays a vital role in maintaining water levels and providing recreational opportunities for the surrounding community.
Situated within the Baltimore District, Lake of The Woods Dam is a key infrastructure component for water enthusiasts and climate advocates alike. With its strategic location and storage capacity, the dam not only supports recreational activities but also contributes to water resource management and flood control efforts in the area. As a regulated and inspected structure, it underscores the importance of responsible dam maintenance and emergency preparedness in safeguarding both the environment and the community.

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.
