Hartrampf Lake Dam dam
Hartrampf Lake Dam
Hartrampf Lake Dam, located in Fulton County, Georgia, is a privately owned earth dam primarily used for recreation. Standing at a height of 32.4 feet with a hydraulic height of 25.7 feet, this structure was completed in 1970 and has a maximum storage capacity of 58 acre-feet. The dam spans 201 feet in length and covers a surface area of 4 acres, serving as a popular spot for outdoor activities in the city of Dunwoody.
Although classified as having a low hazard potential, Hartrampf Lake Dam is subject to regular inspections, with the last assessment conducted in June 2017. The dam's risk assessment is moderate, indicating a level 3 risk. While the condition of the structure is currently not rated, the dam's emergency action plan (EAP) status and risk management measures are yet to be documented. Despite these uncertainties, Hartrampf Lake Dam continues to provide a recreational haven for locals and visitors alike, contributing to the water resource landscape of the area.
With its serene surroundings and moderate risk profile, Hartrampf Lake Dam stands as a testament to the intersection of water resource management and recreational activities. As climate enthusiasts and water resource advocates explore the dam's features and purpose, its role in providing leisure opportunities while maintaining safety standards becomes a focal point of interest. The dam's presence in the Savannah District underscores the importance of balancing environmental considerations with the need for recreational infrastructure in a dynamic climate landscape.

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 Hartrampf Lake Dam
Where does the data for Hartrampf 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.
