Minish Lake Dam dam
Minish Lake Dam
Minish Lake Dam, also known as Iveys Lake Dam, is a privately owned structure located in Jackson, Georgia. Built in 1970 by the Soil Conservation Service (SCS), this earth dam stands at 25 feet high and spans a length of 225 feet, providing recreational opportunities for visitors in the area. With a storage capacity of 95 acre-feet, the dam is primarily used for recreation purposes and has a low hazard potential.
The dam's uncontrolled spillway and outlet gates contribute to its moderate risk assessment of 3, although it has not been officially rated for its condition. Despite not being regulated by the state, the dam undergoes inspections every 5 years to ensure its safety and integrity. Emergency action plans and risk management measures have not been specifically outlined for Minish Lake Dam, highlighting the need for continued monitoring and maintenance to mitigate potential risks associated with the structure.
Situated in the Nashville District of the US Army Corps of Engineers, Minish Lake Dam serves as a vital resource for water enthusiasts and climate advocates in the region. Its scenic location in Commerce offers a tranquil setting for recreational activities, while also posing moderate risks that necessitate ongoing attention and assessment to ensure the safety of the surrounding community and environment.

About Minish Lake Dam
Where does the data for Minish 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 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 below 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.

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.
