Hall Dam Reservoir Report
Nearby: Fogg Dam Acquinton Dam
Last Updated: February 22, 2026
Hall Dam, located in King William, Virginia, is a state-regulated structure managed by the Department of Conservation and Recreation.
Summary
This earth-type dam on Mehixen Creek serves primarily for irrigation purposes, with a storage capacity of 69 acre-feet. With a height of 12 feet and a hydraulic height of 12 feet, the dam's condition is currently not rated, and its hazard potential is undetermined.
While the dam has not been rated for its condition, it undergoes regular inspections with a frequency of one inspection per year. The dam does not have an Emergency Action Plan (EAP) prepared or updated, nor does it have inundation maps in place. Despite these gaps in emergency preparedness, the dam continues to serve its purpose for irrigation and recreation in the area. As an essential water resource structure in the region, further assessments and management measures may be needed to ensure the safety and functionality of Hall Dam for the surrounding community.

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.
