Spalding Lake Dam dam
Spalding Lake Dam
Spalding Lake Dam, located in Roswell, Georgia, is a private-owned structure primarily used for recreational purposes. This earth dam, with a height of 25.3 feet and a hydraulic height of 23.4 feet, stands as a buttress type that spans 120 feet in length. While its hazard potential is classified as low, the risk assessment indicates a moderate level of risk, suggesting a need for cautious monitoring and management.
Despite not being state-regulated, Spalding Lake Dam undergoes inspections every five years, with the last inspection conducted in June 2017. The dam features uncontrolled spillways and outlet gates, emphasizing the importance of emergency preparedness and risk mitigation measures. With a maximum storage capacity of 34 acre-feet and a normal storage level of 25 acre-feet, the dam covers a surface area of 2.5 acres, contributing to the recreational landscape of the area.
As climate change continues to impact water resources and infrastructure, enthusiasts and stakeholders interested in water management and climate resilience can find Spalding Lake Dam as a focal point for monitoring and assessing the intersection of recreational usage and safety regulations. With a focus on risk management and emergency preparedness, this dam serves as a case study for balancing recreational benefits with the need for sustainable and resilient water resource management in the face of changing environmental conditions.

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 Spalding Lake Dam
Where does the data for Spalding 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.
