Summary
With a height of 11.5 feet and a storage capacity of 143.24 acre-feet, this dam plays a crucial role in water resource management in the region. Despite its undetermined hazard potential and lack of a condition rating, the dam is equipped with emergency action plans to ensure the safety of surrounding areas.
The dam, completed in an unspecified year, spans 500 feet in length and covers a surface area of 15.3 acres. Its primary purpose and design specifics are not provided in the data, but it is evident that the dam serves as a vital infrastructure for water storage and regulation. Situated in the Norfolk District, the Cullen Winter Dam stands as a testament to the intersection of private ownership and state regulatory oversight in the management of water resources.
As water resource and climate enthusiasts delve into the details of the Cullen Winter Dam, they will uncover a complex network of state jurisdiction, inspection protocols, and emergency preparedness measures. While certain aspects of the dam's condition and risk assessment remain unclear, its role in maintaining water storage and regulation in Virginia's Accomack County is undeniable. With ongoing monitoring and adherence to safety guidelines, the Cullen Winter Dam continues to be a key player in the region's water infrastructure landscape.

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.
