Halliday Lake Dam #1 dam
Halliday Lake Dam #1
Halliday Lake Dam #1, located in Lumpkin, Georgia, is a privately owned Earth-type dam primarily used for recreation. Constructed in 1940 by the Natural Resources Conservation Service, this dam stands at 16 feet in height with a hydraulic height of 15.8 feet and a length of 460 feet. With a storage capacity of 81 acre-feet and a surface area of 9 acres, the dam serves the purpose of providing recreational opportunities for visitors in the area.
Despite being a low hazard potential structure, Halliday Lake Dam #1 has a moderate risk assessment rating of 3. This dam does not have any associated structures and is not regulated by the state. It features an uncontrolled spillway and outlet gates, with no recent inspection or condition assessment reported. While the dam's emergency action plan status is unknown, it remains an important piece of infrastructure for the local community and water resource enthusiasts interested in its history and purpose.
As part of the Mobile District in Georgia, Halliday Lake Dam #1 contributes to the regional water management system by providing recreational benefits and enhancing the natural landscape. With its unknown designer and current condition assessment, this dam serves as a reminder of the importance of maintaining and managing water resources for both human enjoyment and environmental conservation. For water resource and climate enthusiasts, Halliday Lake Dam #1 offers a fascinating glimpse into the intersection of infrastructure, recreation, and environmental stewardship in the state of Georgia.

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 Halliday Lake Dam #1
Where does the data for Halliday Lake Dam #1 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.
