Rocky Mtn Dam G dam
Rocky Mtn Dam G
Rocky Mtn Dam G, also known as Auxiliary Pool II - Dam G, is a private-owned structure located in Floyd, Georgia, specifically in the city of Armuchee. Completed in 1991, this earth dam stands at a height of 46 feet with a hydraulic height of 47 feet, serving a primary purpose of recreation and other activities. Designed by HARZA Engineering, the dam boasts a multi-arch core type with a rock foundation, providing a storage capacity of 6,500 acre-feet and a normal storage level of 1,800 acre-feet.
Situated on Heath Creek and the Armuchee River, Rocky Mtn Dam G offers a surface area of 200 acres for various water-related activities. Despite its low hazard potential, the dam is regulated by the Federal Energy Regulatory Commission and undergoes inspections every three years, with the last inspection conducted in June 2021. While there are no spillways or outlet gates associated with the structure, its risk assessment indicates a high level of risk management measures in place, ensuring the safety and stability of the dam for both the surrounding community and the environment.
Overall, Rocky Mtn Dam G is a vital component of the water resource infrastructure in Georgia, aligning with the state's jurisdiction and regulations. With its impressive design and capacity for recreation, this dam serves as a testament to responsible water management and the importance of maintaining critical structures for climate resilience and sustainable water use in the region.

About Rocky Mtn Dam G
Where does the data for Rocky Mtn Dam G 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.
