Willow Springs Lake Dam dam
Willow Springs Lake Dam
Willow Springs Lake Dam, also known as Arvida Lake Dam, is a private dam located in Roswell, Georgia. Completed in 1955, this earth dam stands at a height of 30.6 feet and has a length of 550 feet, providing recreational opportunities for visitors in the area. With a normal storage capacity of 195 acre-feet and a maximum storage of 360 acre-feet, the dam serves as an important water resource for the surrounding community.
Managed by the Georgia Safe Dams Program, Willow Springs Lake Dam is subject to regular state inspections and enforcement measures to ensure its safety and functionality. Despite its high hazard potential, the dam's condition assessment in January 2020 deemed it satisfactory, with a moderate risk rating of 3. While the dam features uncontrolled spillways and outlet gates, its risk management measures and emergency action plan status remain unspecified.
Enthusiasts of water resources and climate will find Willow Springs Lake Dam an intriguing structure in Fulton County, Georgia, with its mix of recreational and safety considerations. As a privately owned dam, it plays a crucial role in providing water storage and leisure activities for the local community, while also being subject to state regulations and inspections to mitigate potential risks and ensure public safety.
Dam data reference
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 Willow Springs Lake Dam
Where does the data for Willow Springs 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 High 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.
