Green Lake Dam dam
Green Lake Dam
Green Lake Dam in Pickens, Georgia, is a privately owned earth dam completed in 1970 primarily for recreational purposes. Standing at 29 feet high and stretching 285 feet long, the dam holds a storage capacity of 36 acre-feet, with a normal storage level of 26 acre-feet. Despite being unregulated by the state, Green Lake Dam is inspected periodically, with the last assessment conducted in June 2016, revealing a low hazard potential and a moderate risk assessment rating.
Located within the Mobile District of the US Army Corps of Engineers, Green Lake Dam boasts a serene surface area of 3 acres within a drainage area of 39 square miles. The dam features an uncontrolled spillway and outlet gates, making it a popular destination for water resource and climate enthusiasts seeking outdoor recreational activities. While the condition assessment is currently not rated, the dam's risk management measures are under constant evaluation, ensuring the safety and enjoyment of visitors to this picturesque water resource.
With its tranquil setting and ample storage capacity, Green Lake Dam offers a unique opportunity for visitors to explore and appreciate the intersection of water resources and climate. Despite its age, the dam continues to provide a safe and enjoyable environment for recreational activities, serving as a testament to the importance of responsible dam management in sustaining our natural landscapes. Whether admiring the earth dam's structure or partaking in water-based activities, Green Lake Dam remains a captivating destination for those passionate about our planet's interconnected ecosystem.

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 Green Lake Dam
Where does the data for Green 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.
