Newnan Waterworks Dam # 3 dam
Newnan Waterworks Dam # 3
Newnan Waterworks Dam # 3 in Coweta, Georgia, is a vital structure owned by a public utility that serves as a water supply source for the area. This earth-type dam stands at a height of 46 feet and stretches 875 feet in length, holding a storage capacity of 690 acre-feet. With a surface area of 28 acres, the dam has a spillway type of 'Uncontrolled' and poses a high hazard potential, although its condition assessment was reported as satisfactory during the last inspection in January 2017.
Situated in the Mobile District and regulated by the Georgia Safe Dams Program, Newnan Waterworks Dam # 3 plays a crucial role in managing water resources in the region. While it has not undergone any modifications in recent years, its risk assessment indicates a moderate level of risk. With state permitting, inspection, and enforcement in place, the dam continues to operate effectively, ensuring the safety and reliability of the water supply system for the community.
For water resource and climate enthusiasts, Newnan Waterworks Dam # 3 represents a significant infrastructure supporting water supply needs in Coweta, Georgia. Its design and construction details, along with regulatory oversight and risk assessment, underscore the importance of maintaining and monitoring such critical structures to safeguard water resources and mitigate potential hazards in the face of changing climate patterns and environmental challenges.

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 Newnan Waterworks Dam # 3
Where does the data for Newnan Waterworks Dam # 3 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.
