Summary
Completed in 1989, this earth dam stands at a height of 67.3 feet and has a storage capacity of 29,632 acre-feet. Situated on the Great Creek - VAHU6 CM16 Great Creek river system, the dam covers a surface area of 238.34 acres and has a drainage area of 41.06 square miles.
Managed by the local government, the dam is regulated and inspected by the Department of Conservation and Recreation in Virginia. Despite being classified with a high hazard potential, the dam's condition is assessed as fair as of the last inspection in January 2021. With an uncontrolled spillway system and a maximum discharge capacity of 35,266 cubic feet per second, Great Creek Dam # 6a plays a crucial role in mitigating flood risks in the area while also providing recreational opportunities for the community.
Water resource and climate enthusiasts can appreciate the significance of Great Creek Dam # 6a in safeguarding the surrounding region from potential flooding events. With its moderate risk assessment and fair condition, ongoing management measures are in place to ensure the dam's continued effectiveness in flood risk reduction. The collaboration between local government and regulatory agencies underscores the commitment to maintaining the integrity and safety of this essential infrastructure for the community of Lawrenceville and beyond.

Dam Data Reference
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.
