Fgh3 Fort Green Mine dam
Fgh3 Fort Green Mine
Fgh3 Fort Green Mine, located in Duettes, Florida, is a privately-owned tailings dam that was completed in 1980. This dam, primarily designed by Ardaman & Associates, stands at a height of 40 feet with a hydraulic height of 35 feet and a structural height of 42 feet. It serves the purpose of tailings storage and has a storage capacity of 38,000 acre-feet, with a normal storage capacity of 35,000 acre-feet.
The dam overlooks Horse Creek and has a controlled spillway with a width of 80 feet. With a significant hazard potential and a very high risk assessment rating (1), Fgh3 Fort Green Mine is under state regulation by the Florida Department of Environmental Protection. Although the dam has not been rated for its condition assessment, it undergoes regular state inspections, with the last inspection conducted in January 2006. The surrounding area has a drainage area of 1.56 square miles and a maximum discharge capacity of 60 cubic feet per second.
For water resource and climate enthusiasts, Fgh3 Fort Green Mine presents an intriguing case study in dam construction and management. With its unique design features and risk profile, this privately-owned dam serves as a focal point for understanding the intersection of human activities with natural water systems. As efforts continue to monitor and regulate the dam's operation, it offers valuable insights into the challenges and responsibilities associated with maintaining water infrastructure in a changing climate.

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 Fgh3 Fort Green Mine
Where does the data for Fgh3 Fort Green Mine 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 Significant 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.
