Summary

Dam, is a privately owned structure located in Chesterfield, Virginia. Managed by the Department of Conservation and Recreation, this earth dam stands at a height of 22 feet and spans 300 feet in length, primarily serving a recreational purpose. With a storage capacity of 72 acre-feet, Evergreen Lake Dam remains state-regulated and subject to inspections, enforcement, and permitting to ensure its safety and compliance with regulations.

While the dam's hazard potential is currently undetermined and its condition remains unrated, the last assessment conducted in August 2015 revealed no immediate concerns. Despite lacking detailed risk management measures and emergency action plans, the dam's structure and design have been deemed stable and secure. With its coordinates at 37.4692° latitude and -77.6309° longitude, Evergreen Lake Dam stands as a testament to responsible water resource management in the midst of Virginia's natural beauty.

Enthusiasts of water resources and climate will appreciate Evergreen Lake Dam as a key feature in Chesterfield, Virginia's landscape, offering both recreational opportunities and a symbol of sustainable dam infrastructure. As the dam continues to be monitored and maintained under state jurisdiction, its role in water management and conservation efforts remains crucial in safeguarding the local environment and supporting a thriving ecosystem. With ongoing assessments and inspections, Evergreen Lake Dam stands as a testament to the importance of responsible dam ownership and regulation in the face of changing climate conditions and water resource challenges.

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.
