Summary

Built in 1969, this structure on the C-32C (Trout-Joel Canal) is owned by the state and is subject to state permitting, inspection, and enforcement. With a low hazard potential and a height of 19 feet, S-58 has a storage capacity of 73,000 acre-feet and a normal storage level of 43,000 acre-feet.

Although S-58 is primarily used for flood risk reduction, it also serves irrigation purposes in the area. The dam has a structural height of 14 feet and a length of 50 feet, covering a surface area of 3,842 acres. Despite its age, S-58 has not been rated for its condition assessment, and there is no information available on its emergency action plan or risk management measures. The dam is not operated by the US Army Corps of Engineers and has not been modified in recent years.

Overall, S-58 plays a crucial role in managing water resources in Osceola County, Florida, and contributes to the overall water infrastructure of the region. As a state-regulated structure with a focus on flood risk reduction, it is essential for ensuring the safety and well-being of the surrounding communities. Further assessments and updates may be needed to enhance the dam's resilience and preparedness for potential risks and emergencies in the future.

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.
