Summary
Completed in 2002, this Earth-type dam stands at a height of 50 feet with a hydraulic height of 45 feet, serving a primary purpose of tailings storage. With a storage capacity of 25,000 acre-feet and a surface area of 508 acres, the dam presents a significant hazard potential and a very high risk assessment rating.
Despite not having a condition assessment rating, Fgh4 Fort Green Mine's dam boasts a controlled spillway with a width of 128 feet and a maximum discharge of 80 cubic feet per second. The dam has not been modified in recent years and lacks emergency action plans or updated contact information. The risk of inundation is considered very high, making it crucial for water resource and climate enthusiasts to monitor this site closely for any potential environmental risks or safety concerns.
With its location in Hardee County, Florida, Fgh4 Fort Green Mine stands as a critical infrastructure on the Peace River, requiring consistent inspection, enforcement, and risk management measures to ensure the safety and sustainability of the surrounding environment. As water resource and climate enthusiasts, understanding the nuances of this dam's design, purpose, and potential risks is essential in safeguarding the water resources and ecosystems that depend on its proper functioning.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
