Summary
This earth dam, standing at a height of 23 feet with a length of 400 feet, serves primarily for recreational purposes along the tributary of Deep Creek. With a storage capacity of 177 acre-feet, the dam has not been rated for its condition assessment and poses an undetermined hazard potential.
Located within the Norfolk District of Virginia, Blenheim Road Se Dam is yet to undergo a comprehensive risk assessment or have an Emergency Action Plan (EAP) in place. Despite its unclassified risk status, the dam remains subject to state inspection, enforcement, and permitting processes. As water resource and climate enthusiasts, the unique characteristics of this dam present an opportunity to study the environmental impact and resilience of such structures within the region.
As the dam continues to attract visitors for recreational activities, the lack of a formal risk assessment raises questions about its long-term safety and management. For those interested in water resource management and climate adaptation, Blenheim Road Se Dam offers a case study in the intersection of infrastructure, regulation, and environmental stewardship. Further research and attention to the dam's condition and emergency preparedness could provide valuable insights into sustainable dam management practices in the face of changing climate conditions.

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.
