Lewis Mill Lake Dam dam
Lewis Mill Lake Dam
Lewis Mill Lake Dam, located in Dooly, Georgia, was completed in 1958 with a primary purpose of recreation. This private earth dam stands at a height of 15.6 feet, with a hydraulic height of 14.9 feet, and a length of 420 feet. The dam has a storage capacity of 510.5 acre-feet and a surface area of 41.4 acres, making it a popular spot for water activities and outdoor enthusiasts in the area.
While the dam has a low hazard potential and is currently not rated for its condition, it is inspected every 5 years to ensure its safety. The spillway type is uncontrolled, with uncontrolled outlet gates. The risk assessment for Lewis Mill Lake Dam is moderate (3), indicating a need for ongoing monitoring and risk management measures. Despite not being state-regulated, the dam is under the jurisdiction of Georgia, with inspections conducted to maintain its integrity and safety for the surrounding community.
With its picturesque location in Vienna, Georgia, Lewis Mill Lake Dam offers a serene setting for recreational activities and serves as a vital water resource for the local area. Enthusiasts of water resources and climate will appreciate the significance of this dam in providing leisure opportunities and contributing to the environmental landscape of Dooly County.

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 Lewis Mill Lake Dam
Where does the data for Lewis Mill 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.
