Summary
This earth-type dam on the Pagan River stands at a height of 14 feet and has a storage capacity of 172 acre-feet, primarily serving recreational purposes. While the dam's hazard potential is currently undetermined and its condition is not rated, regular inspections are conducted to ensure its safety and functionality.
The dam, with a hydraulic height matching its structural height of 14 feet, is a significant feature in the Norfolk District managed by the US Army Corps of Engineers. Although details about the dam's construction year and length are not specified, its role in providing recreational opportunities in the area is clear. The dam's emergency action plan status, risk assessment, and management measures are currently not outlined, suggesting a potential area for future development and enhancement in ensuring the safety and resilience of this vital water resource.
Overall, Wrenns Dam stands as a crucial asset for water resource management and climate enthusiasts, offering insights into the intersection of infrastructure, recreation, and environmental stewardship. As efforts continue to monitor and assess the dam's condition and functionality, there is a clear opportunity to further enhance its safety measures, emergency preparedness, and risk management strategies. With its location on the Pagan River and its significance in the local community, Wrenns Dam represents a valuable piece of Virginia's water infrastructure landscape that warrants ongoing attention and investment.

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.
