Summary
This earth dam, with a structural height of 45 feet and a length of 500 feet, primarily serves the purpose of recreation along the TR-White Walnut Run river. Despite its undetermined hazard potential and unassessed condition, the Department of Conservation and Recreation in Virginia ensures that the dam undergoes regular inspections, permitting, and enforcement to guarantee public safety.
Situated in the Baltimore District, Seven Islands Dam is a vital component of the local landscape, offering a storage capacity of 1000 acre-feet. The dam's primary owner, a private entity, collaborates with state agencies to uphold regulatory standards and ensure compliance with inspection protocols. While the dam's risk assessment, emergency action plan, and inundation maps remain pending, the dedication to maintaining this essential infrastructure underscores the commitment to safeguarding water resources and mitigating potential hazards.
As climate change intensifies, the importance of resilient water infrastructure like Seven Islands Dam cannot be overstated. With Abigail Davis Spanberger representing the district in Congress, the focus on sustainable water management and adaptive strategies becomes increasingly crucial. By prioritizing safety, regulatory compliance, and potential risk mitigation measures, Seven Islands Dam serves as a beacon of responsible stewardship in the face of evolving environmental challenges.

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.
