Summary
It was designed by Ardam and Associates and completed in 2002 for the primary purpose of tailings storage. The dam is classified as an earth dam with a height of 40 feet and a hydraulic height of 35 feet, providing a maximum storage capacity of 16,500 acre-feet and a normal storage capacity of 15,995 acre-feet.
With a significant hazard potential and a very high risk assessment rating, Sfm 5 - Mosaic is closely regulated by the Florida Department of Environmental Protection (FDEP). The dam's controlled spillway has a width of 128 feet, and it has never been modified since its completion. The dam covers a surface area of 457 acres and has a drainage area of 0.71 square miles, with a maximum discharge capacity of 80 cubic feet per second.
Although the dam's condition assessment is currently not rated, its last inspection was conducted in January 2006. The emergency action plan (EAP) for Sfm 5 - Mosaic is not rated as meeting guidelines, and there is no available information on the preparation of inundation maps or risk management measures. However, with its strategic location and high-risk potential, continuous monitoring and maintenance are crucial to ensure the safety and integrity of Sfm 5 - Mosaic for the surrounding community and water resources.

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.
