Lee & Gordon Mill Dam dam
Lee & Gordon Mill Dam
Lee & Gordon Mill Dam, located in Chickamauga, Georgia, stands as a historic structure completed in 1836. With a primary purpose categorized as "Other," this masonry dam on the West Chickamauga River boasts a height of 12.5 feet and a storage capacity of 92 acre-feet. The dam, with a unique buttress core design, spans 65 feet in length and covers a surface area of 23 acres.
Despite being labeled as "Undetermined" in terms of hazard potential and "Not Rated" for condition assessment, Lee & Gordon Mill Dam presents a moderate risk level of 3. It operates with uncontrolled spillways and outlets, indicating a need for further evaluation of its safety measures. The dam, owned by a local government entity, serves as a captivating reminder of Georgia's rich water resource history, attracting climate and water enthusiasts alike with its intriguing historical and structural features.
As climate change continues to impact water resources, Lee & Gordon Mill Dam stands as a tangible representation of the delicate balance between human development and environmental sustainability. With its unique design and historical significance, this masonry dam serves as a focal point for discussions on risk management, emergency preparedness, and the importance of maintaining and preserving our water infrastructure in the face of evolving climate challenges.
Dam data reference
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 Lee & Gordon Mill Dam
Where does the data for Lee & Gordon Mill 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.
