Summary
Lucie, Florida, is a state-regulated earth dam designed for flood risk reduction along the C-23A & C-24 rivers and streams. Completed in 1960, this dam stands at a height of 53 feet and has a maximum storage capacity of 3,420 acre-feet, with a normal storage capacity of 1,825 acre-feet. The dam spans 67 feet in length and covers a surface area of 65 acres.
Despite its significant hazard potential, S-49's condition assessment has not been rated, and its last inspection date was recorded as far back as July 1905. It is unclear whether this dam meets emergency action plan guidelines or has inundation maps prepared. The dam's risk management measures, risk assessment, and emergency contact information are also not currently updated or available.
Water resource and climate enthusiasts interested in S-49 will be intrigued by the dam's crucial role in flood risk reduction in the St. Lucie area. With its state-regulated status and strategic location along the C-23A & C-24 rivers, S-49 serves as a key infrastructure for managing water flow and protecting nearby communities from potential flooding events. However, the lack of recent inspections and updated emergency preparedness information raise concerns about the dam's current safety and resilience in the face of changing climate conditions. Addressing these gaps in monitoring and risk management will be essential for ensuring the long-term effectiveness of S-49 in safeguarding the surrounding environment and residents.

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.
