Fort Green Fg-2 dam
Fort Green Fg-2
Fort Green Fg-2 is a privately-owned dam located in Polk, Florida, along Payne Creek. This earth dam, completed in 1977, serves primarily for tailings storage with a height of 23 feet and a length of 13,730 feet. The dam has a storage capacity of 12,144 acre-feet and covers a surface area of 528 acres. Although the dam is not currently rated for condition assessment, it is classified as having a significant hazard potential.
With a maximum discharge of 220 cubic feet per second, Fort Green Fg-2 plays a critical role in water resource management in the region. It is regulated by the state of Florida and is subject to regular inspections, permitting, and enforcement. While the dam has not been modified in recent years and does not have an Emergency Action Plan (EAP) in place, it is essential for stakeholders, especially in the event of a potential emergency or risk assessment in the future.
Located within the Jacksonville District of the US Army Corps of Engineers, Fort Green Fg-2 stands as a vital infrastructure for water control and conservation efforts. As water resource and climate enthusiasts continue to monitor and assess the condition of dams like Fort Green Fg-2, it underscores the importance of sustainable management practices to ensure the safety and integrity of these critical structures for the surrounding communities and ecosystems.

About Fort Green Fg-2
Where does the data for Fort Green Fg-2 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 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.
Dam data reference
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.
