Edwards Lower Twin Lake Dam dam
Edwards Lower Twin Lake Dam
Edwards Lower Twin Lake Dam, located in Barrow, Georgia, was completed in 1955 with the primary purpose of recreation. This private earth dam stands at 18 feet high and spans 200 feet in length, creating a surface area of 7 acres and a storage capacity of 90 acre-feet. The dam is classified as having a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment.
Although the dam is not state-regulated, it is important to note that it poses a moderate risk level, indicating potential vulnerabilities that need to be addressed. The dam features uncontrolled spillways and outlet gates, with no designated inspection frequency listed. Despite its age, the dam has not undergone any significant modifications in recent years, with the last recorded inspection dating back to January 2003.
For water resource and climate enthusiasts, Edwards Lower Twin Lake Dam serves as a focal point for understanding the intersection of recreational infrastructure and environmental stewardship. Its presence not only provides a scenic backdrop for outdoor activities but also underscores the importance of ongoing monitoring and maintenance to ensure the safety and sustainability of our water resources.

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 Edwards Lower Twin Lake Dam
Where does the data for Edwards Lower Twin 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.
