Shirley Bell Dam Reservoir Report
Last Updated: February 22, 2026
Shirley Bell Dam, located in Prince William, Virginia, is a privately owned structure that falls under the jurisdiction of the Department of Conservation and Recreation in the state.
Summary
Standing at a height of 33 feet, the dam has a storage capacity of 24.02 acre-feet and a normal storage level of 17.8 acre-feet. With a surface area of 1.6 acres, the dam's hazard potential is currently listed as undetermined, and its condition has not been rated.
Despite lacking detailed information on its construction and specific purposes, Shirley Bell Dam serves as a vital water resource in the region. Its presence contributes to the regulation of water levels and storage, playing a crucial role in managing water flow and potential flooding in the area. As water resource and climate enthusiasts, understanding the infrastructure and maintenance of dams like Shirley Bell is essential for ensuring the sustainability and safety of our water systems in the face of changing climate patterns and increasing water demands.

Dam Data Reference
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.
