Thompson Lake Dam dam
Thompson Lake Dam
Thompson Lake Dam, located in Arlington, Georgia, was completed in 1965 and serves multiple purposes including fire protection and providing a habitat for small fish. The dam is privately owned and stands at a height of 10.8 feet with a storage capacity of 126 acre-feet. With a low hazard potential and a moderate risk assessment rating, Thompson Lake Dam plays a crucial role in water resource management in Baker County.
Despite being unregulated by the state, Thompson Lake Dam undergoes regular inspections every five years to ensure its structural integrity and safety. The dam features an uncontrolled spillway and outlet gates, contributing to its low hazard potential. The surrounding area has a drainage area of 730 acres, with a surface area of 16 acres, making it a significant water resource for the region. With its strategic location and essential functions, Thompson Lake Dam is a vital piece of infrastructure for both water conservation and climate sustainability efforts in the area.
Although not rated for its condition, Thompson Lake Dam remains an integral part of the local ecosystem, providing water storage, fire protection, and recreational opportunities for the community. With a risk management plan in place and regular inspections, the dam continues to serve its purpose effectively while mitigating potential hazards. As climate change impacts water resources, the importance of structures like Thompson Lake Dam in sustainable water management practices becomes increasingly apparent, emphasizing the need for continued monitoring and maintenance to ensure its long-term functionality.

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 Thompson Lake Dam
Where does the data for Thompson Lake 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 Low 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.
