Summary
Completed in 1976, this dam serves primarily for tailings storage with a height of 50 feet and a length of 13,200 feet. With a maximum storage capacity of 4,375 acre-feet and a normal storage of 3,000 acre-feet, Es-Tech Sa-13 covers an area of 88 acres and has a low hazard potential rating. Despite its low hazard potential, the risk assessment for this dam indicates a very high risk level.
Managed by the Jacksonville District of the US Army Corps of Engineers, Es-Tech Sa-13 is regulated by the state of Florida and undergoes regular inspections, with state permitting, inspection, and enforcement mechanisms in place. Although the dam has not been rated for condition assessment, it meets guidelines for emergency action plans. The spillway type for this dam is controlled, although details on outlet gates, associated structures, and emergency preparedness measures are not provided in the available data. Overall, Es-Tech Sa-13 presents an interesting case study for water resource and climate enthusiasts, with its unique location, purpose, and risk profile.

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.
