Manning Lake Dam No. 1 dam
Manning Lake Dam No. 1
Manning Lake Dam No. 1, located in Newton, Georgia, is a privately owned structure primarily used for recreation purposes. Built in 1970, this earth dam stands at a height of 31 feet and has a storage capacity of 112 acre-feet. The dam, with a length of 405 feet, serves the Snapping Shoals Community, offering a surface area of 8 acres for various recreational activities.
Despite being unlisted as a state-regulated structure, Manning Lake Dam No. 1 is inspected regularly, with the last assessment conducted in 2002. With a low hazard potential and a moderate risk assessment rating, this dam is considered to be in good condition, although its emergency preparedness measures are not specified. The dam's uncontrolled spillway and outlet gates suggest a simple design, catering to the community's recreational needs while ensuring safety and risk management.
For water resource and climate enthusiasts, Manning Lake Dam No. 1 presents an intriguing case study of a privately owned earth dam in Georgia. With its unique design features and recreational focus, this structure exemplifies the intersection of human-made infrastructure and natural water systems, showcasing the importance of maintaining and monitoring dams for both safety and environmental sustainability. Further exploration of Manning Lake Dam No. 1 could provide valuable insights into the management of similar structures in the region and their role in balancing human recreation with water resource conservation efforts.

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 Manning Lake Dam No. 1
Where does the data for Manning Lake Dam No. 1 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.
