Summary

With a height of 13 feet and a length of 1160 feet, this dam has a storage capacity of 668 acre-feet and covers a surface area of 61 acres. Despite being classified as having a high hazard potential, the dam's condition assessment is rated as fair, as of the last inspection in January 2021.

Managed by the Department of Conservation and Recreation in Virginia, B - 1 Pond Dam is subject to state regulation, permitting, inspection, and enforcement. The dam's emergency action plan was last revised in December 2013, and it meets established guidelines for emergency preparedness. While the dam's risk assessment and management measures are currently unspecified, its location within a drainage area of 0.59 square miles underscores the significance of its role in water resource management and climate resilience for the region.

Overall, B - 1 Pond Dam represents a critical infrastructure asset for water storage and management in Isle of Wight, Virginia. Its strategic location and operational capabilities contribute to the conservation and regulation of water resources in the area, highlighting the importance of ongoing monitoring and maintenance to ensure safety and efficiency in the face of changing climate conditions and potential hazards.

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.
