Summary
Built for purposes other than flood control or water supply, this earth-type dam was designed by Froehling and Robertson, Inc. Despite being regulated and inspected by the Department of Conservation and Recreation in Virginia, its hazard potential is currently categorized as undetermined, with a fair condition assessment as of November 2019.
As a key component of the local water resource infrastructure, Acquinton Dam plays a vital role in managing water levels and ensuring the stability of the surrounding area. While the dam's primary purpose may not be conventional, its impact on the local environment and community cannot be understated. With its location in Congressional District 01, Virginia, Acquinton Dam stands as a testament to the importance of private ownership in maintaining crucial water management structures.
Enthusiasts of water resources and climate will find Acquinton Dam to be a fascinating study in the intersection of private ownership, regulatory oversight, and environmental impact. Its presence highlights the complex network of dams and reservoirs that contribute to water management efforts in Virginia, serving as a reminder of the ongoing need for infrastructure maintenance and risk assessment in the face of changing climate conditions.

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.
