Ramsden Lake Dam dam
Ramsden Lake Dam
Ramsden Lake Dam, located in Stone Mountain, Georgia, is a privately-owned earth dam primarily used for recreation purposes. Standing at 23 feet tall with a hydraulic height of 17 feet, this dam holds a storage capacity of 80 acre-feet, with a normal storage level of 58 acre-feet. The dam spans 450 feet in length and covers an impressive surface area of 8 acres.
Despite being unregulated by the state and having a low hazard potential, Ramsden Lake Dam has not been inspected since February 1984 and is currently rated as "Not Rated" in terms of its condition assessment. However, with a moderate risk assessment of 3 out of 5, there is a need for further evaluation and potential risk management measures to ensure the safety of the surrounding area. While the dam has not been modified or updated in recent years, its uncontrolled spillway and outlet gates may pose a moderate risk to its overall integrity.
Overall, Ramsden Lake Dam serves as a key recreational spot in DeKalb County, but its outdated inspection records and moderate risk assessment highlight the importance of continued monitoring and maintenance to mitigate potential hazards. As climate change continues to impact water resources, it is crucial for dam owners and regulators to prioritize safety measures to protect the surrounding community and environment.

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 Ramsden Lake Dam
Where does the data for Ramsden 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.
