Gilliam Dam dam
Gilliam Dam
Gilliam Dam, located in Halifax, Virginia, is a private-owned structure regulated by the Department of Conservation and Recreation. Standing at a height of 43 feet, the earth dam's primary purpose is for recreation, specifically on TR-Lawsons Creek. With a storage capacity of 95 acre-feet, the dam is a vital resource for the surrounding community, providing a picturesque setting for outdoor activities and water enthusiasts to enjoy.
Despite its undetermined hazard potential and not yet rated condition assessment, Gilliam Dam remains a popular destination for locals and visitors alike. The dam, which was completed in an unspecified year, offers a serene atmosphere for fishing, boating, and other recreational pursuits. With its strategic location and beautiful surroundings, the dam serves as a focal point for water resource and climate enthusiasts interested in exploring the natural beauty of Virginia's landscape.
As the Wilmington District of the USACE oversees the dam, stakeholders and authorities continue to monitor and inspect Gilliam Dam to ensure its safety and functionality. While the dam's emergency action plan and risk assessment details are yet to be fully established, the community can take comfort in knowing that measures are in place to address any potential risks or emergencies that may arise. With its rich history and recreational value, Gilliam Dam remains a cherished landmark in Halifax, Virginia, inviting all to appreciate the symbiotic relationship between water resources and climate in the region.

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.
Plan around the weather

About Gilliam Dam
Where does the data for Gilliam Dam 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 Undetermined 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.
