Moon Lake Dam Enlargement dam
Moon Lake Dam Enlargement
Moon Lake Dam Enlargement, also known as Lake Legacy Dam, is a private-owned structure located in Kennesaw, Georgia. The dam, primarily used for recreation, is an earth dam with a buttress core type and a height of 20.2 feet. It has a storage capacity of 87 acre-feet, with a normal storage level of 52 acre-feet and a surface area of 6.6 acres.
Although the dam's hazard potential is currently undetermined and its condition is not rated, it is considered to have a moderate risk level of 3. The dam features an uncontrolled spillway and outlet gates, with no associated structures or inspection history available. Given its location in Cobb County, Georgia, the dam plays a crucial role in providing recreational opportunities for residents and visitors alike.
With its picturesque setting and recreational value, the Moon Lake Dam Enlargement project presents an exciting opportunity for water resource and climate enthusiasts to explore and appreciate the importance of sustainable dam management practices. As efforts continue to evaluate and improve the dam's safety and functionality, the project serves as a reminder of the critical role that dams play in providing water resources and recreational opportunities in communities across Georgia.

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 Moon Lake Dam Enlargement
Where does the data for Moon Lake Dam Enlargement 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.
