Summary

Standing at a height of 20.5 feet and stretching 450 feet in length, this dam boasts a storage capacity of 117.67 acre-feet and covers a surface area of 10.1 acres. Despite its undetermined hazard potential and unrated condition assessment, the dam is subject to regular inspections by state authorities to ensure its safety and compliance with regulations.

The dam, constructed with a primary purpose unspecified in the available data, remains a key feature in the Norfolk District and is overseen by Congresswoman Abigail Davis Spanberger. While specifics regarding its design, type, and foundations are unknown, Ciejek Dam plays a crucial role in water resource management in the region. With a normal storage capacity of 67.67 acre-feet and a hydraulic height matching its structural height at 20.5 feet, the dam serves as a vital infrastructure for water supply and flood control.

As water resource and climate enthusiasts explore the significance of Ciejek Dam, its role in the local ecosystem and community becomes increasingly apparent. With its presence contributing to the overall water management efforts in Virginia, the dam represents a blend of private ownership, state regulation, and sustainable practices. While certain details about its construction and modification history remain undisclosed, the dam's impact on the surrounding environment and its importance in safeguarding against potential risks highlight the critical role it plays in the region's water infrastructure.

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.
