Fort Green Fg-1 dam
Fort Green Fg-1
Fort Green Fg-1 is a privately owned dam located in Polk, Florida, along the Payne Creek. Built in 1975 for tailings purposes, this earth dam stands at a height of 25 feet and stretches 19,000 feet in length, with a storage capacity of 12,575 acre-feet. The dam is regulated and permitted by the state of Florida, with inspection and enforcement measures in place to ensure its safety and compliance with regulations.
With a significant hazard potential, Fort Green Fg-1 has not been condition rated, and emergency action plans have not been prepared or updated. Despite these gaps, the dam serves as a vital structure for water resource management in the region, providing flood control and storage capabilities. As an integral part of the local water infrastructure, Fort Green Fg-1 plays a crucial role in maintaining the ecological balance and water supply for the surrounding area.
As water resource and climate enthusiasts, it is important to monitor the condition and management of dams like Fort Green Fg-1 to ensure their safety and effectiveness in the face of changing environmental conditions. By staying informed and advocating for proper maintenance and emergency preparedness, we can help protect our water resources and communities from potential risks associated with dam failures.

About Fort Green Fg-1
Where does the data for Fort Green Fg-1 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.

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.
