Summary

Completed in 1979, this dam serves a primary purpose of water supply and is owned by the state of Florida. With a maximum storage capacity of 242 acre-feet and a normal storage of 136 acre-feet, S-338 plays a crucial role in ensuring water availability for the surrounding area.

Standing at a height of 26 feet, S-338 has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. While the last inspection date recorded was in 1905, the dam is subject to state permitting, inspection, and enforcement to ensure its continued safe operation. Although there are no associated structures or federal agency involvement with S-338, its importance in water management for the region cannot be understated.

With its location in the heart of New Tamiami Airport, S-338 is a key component in the infrastructure that supports water supply needs in the area. Climate and water resource enthusiasts can appreciate the vital role that S-338 plays in maintaining water security and mitigating potential risks associated with water scarcity in the region. As efforts continue to manage and regulate this dam, it remains a critical piece of the water resource puzzle in Miami-Dade, Florida.

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.
