Summary
Completed in 1955, this earth dam stands at a height of 12 feet and has a length of 462 feet, with a storage capacity of 67 acre-feet. The dam sits on the TR-Santo Arroyo Creek in the city of Van Norman and is regulated by the state agency DNRC.
With a low hazard potential and a condition assessment of "Not Rated," Virginia serves as a vital resource for water management and conservation in the region. It is equipped with a spillway width of 100 feet and has the capacity to discharge up to 500 cubic feet per second in case of emergencies. Although not currently rated for its condition, the dam is subject to state inspection, permitting, and enforcement to ensure its structural integrity and safety.
Water resource and climate enthusiasts in the area can appreciate Virginia's contribution to fire protection, livestock watering, and aquatic habitat preservation. As a key component of the local ecosystem, this dam plays a crucial role in managing water resources and supporting the surrounding environment. With its strategic location and purposeful design, Virginia stands as a testament to sustainable water management practices in the region, highlighting the importance of responsible stewardship for the future.

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.
