Summary

This earth dam, standing at a height of 67 feet and spanning 2100 feet in length, serves primarily for flood risk reduction and water supply purposes along the Dry Run river. With a storage capacity of 1232 acre-feet and a surface area of 34 acres, the dam plays a crucial role in managing the water resources in the region.

Managed by the Department of Conservation and Recreation in Virginia, Dry Run Dam #101 has a high hazard potential but is currently in satisfactory condition, as assessed during the last inspection in July 2020. The dam's emergency action plan, last revised in January 2016, ensures that necessary measures are in place for any potential risks. Despite not being under the jurisdiction of the US Army Corps of Engineers, the dam remains a vital asset for flood control and water management in the area, contributing to the overall resilience of the region's water resources and infrastructure.

Located within the Norfolk District and with Congressman Ben Cline representing the area, Dry Run Dam #101 stands as a testament to effective state-regulated water resource management. With its strategic position and significant impact on flood risk reduction in the region, the dam serves as a critical infrastructure for safeguarding communities and ecosystems against the challenges posed by climate change and water scarcity.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
