Summary

Completed in 1980, this dam has a height of 40 feet and a hydraulic height of 35 feet, with a capacity of 33,000 acre-feet. The dam spans a length of 12,539 feet and sits on the Horse Creek, within the jurisdiction of the Florida Department of Environmental Protection.

With a spillway type of 'Controlled' and a spillway width of 64 feet, Fgh2 Fort Green Mine poses a significant hazard potential and is classified as having a very high risk (1) according to the risk assessment. The dam's condition has not been rated, and the last inspection conducted was in 2006. Although the dam has not been modified in recent years, it remains under state regulation, inspection, and enforcement to ensure public safety and water resource protection in the area.

Located in the city of Duette and managed by a private entity, Fgh2 Fort Green Mine serves as a crucial water management structure in the region, with a surface area of 858 acres and a drainage area of 1.34 square miles. As water resource and climate enthusiasts, understanding the design, purpose, and risk factors associated with dams like Fgh2 Fort Green Mine is essential for promoting sustainable water management practices and ensuring the resilience of our water infrastructure in the face of changing climate conditions.

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. 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

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, 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.
