Providence Road Lake Dam dam
Providence Road Lake Dam
Providence Road Lake Dam, located in Roswell, Georgia, is a privately owned earth dam primarily used for recreation. Standing at a height of 28 feet with a hydraulic height of 26 feet, this dam spans 190 feet in length and holds a maximum storage capacity of 82 acre-feet. The dam's surface area covers 2.6 acres, providing a serene backdrop for outdoor enthusiasts to enjoy various water activities.
Designed by McGill - Schnabel, the Providence Road Lake Dam has an undetermined hazard potential and is currently rated as "Not Rated" in terms of condition assessment. Despite being deemed as moderate risk, the dam has not been inspected since June 2017, with an inspection frequency of 5 years. While it remains unregulated by the state, the dam's uncontrolled spillway and outlet gates add to its unique design features, making it a point of interest for water resource and climate enthusiasts.
With its picturesque location and potential for recreational use, the Providence Road Lake Dam offers a tranquil setting for visitors to appreciate the beauty of nature while also highlighting the importance of maintaining and monitoring dam safety. As climate change continues to impact water resources, understanding the risk management measures associated with dams like Providence Road Lake Dam becomes crucial in ensuring the safety and preservation of these structures for future generations.

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 Providence Road Lake Dam
Where does the data for Providence Road 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 Undetermined 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.
