Great Creek Dam # 6a dam
Great Creek Dam # 6a
Great Creek Dam # 6a, also known as County Park At Great Creek, is a vital asset located in Brunswick, Virginia, serving multiple purposes including flood risk reduction, recreation, and water supply. 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.

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.
- 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.
- 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.
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, environmental 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.

About Great Creek Dam # 6a
Where does the data for Great Creek Dam # 6a come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the High hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
