Summary
Standing at 55 feet tall with a hydraulic height of 50 feet, this dam on the Peace River has a storage capacity of 37,000 acre-feet and covers a surface area of 654 acres. With a controlled spillway width of 128 feet and a maximum discharge of 80 cubic feet per second, this dam plays a crucial role in regulating water flow in the region.
Managed by the Florida Department of Environmental Protection (FDEP), Sfm1 Mosaic is subject to regular state inspection, enforcement, and permitting to ensure its structural integrity and compliance with environmental regulations. Despite being classified as "Significant" in terms of hazard potential, the condition of the dam is currently listed as "Not Rated." With a risk assessment rating of "Very High (1)", it is evident that Sfm1 Mosaic is a key asset in water resource management in the area, especially given its location along the Peace River in Fort Meade.
As a vital component of the water infrastructure in Polk, Florida, Sfm1 Mosaic serves as a critical structure for flood control, water storage, and environmental protection. With its significant storage capacity and strategic location, this dam plays a crucial role in mitigating flood risks and supporting sustainable water resource management practices in the region. As climate change impacts continue to pose challenges for water resources, the management and maintenance of dams like Sfm1 Mosaic will be essential in ensuring the resilience and sustainability of water systems in the face of a changing climate.

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.
