Summary
Standing at a height of 20 feet with a length of 800 feet, this earth dam offers a storage capacity of 90 acre-feet, with a normal storage level of 72 acre-feet. The dam, constructed by the Department of Conservation and Recreation, is regulated by the state and undergoes regular inspections, ensuring its safety and functionality for both recreational and environmental purposes.
Although the hazard potential of Mathews Dam is considered undetermined and its condition is not rated, the structure meets state regulatory guidelines and has not required any emergency action plans thus far. With its picturesque location and ample storage capacity, the dam provides opportunities for activities such as boating, fishing, and wildlife observation. While details about the dam's construction date and modifications remain unspecified, its presence along the TR-Gap Run river contributes to the overall water resource management and climate resilience efforts in the region.
As a notable feature within the Baltimore District, Mathews Dam reflects the commitment to water conservation and recreational access in Virginia. With its state-regulated status and adherence to inspection protocols, the dam serves as a vital resource for both residents and visitors, highlighting the importance of responsible dam ownership and management.

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.
