Summary

Built in 1984, this earth-type dam stands at a height of 60 feet and has a maximum storage capacity of 2000 acre-feet. The dam serves primarily for tailings storage purposes and has a significant hazard potential, with a moderate risk assessment rating.

Despite being in a state-regulated jurisdiction with permitting, inspection, and enforcement protocols in place, Temple Terrace (Ne) A has not been rated for its condition. The dam's spillway type is uncontrolled, with a width of 16 feet, and it has a downstream drainage area of 0.05 square miles. The dam's hydraulic height is 55 feet, while the structural height reaches 65 feet, and the dam length spans over 5000 feet.

In the event of an emergency, it is crucial for the owners of Temple Terrace (Ne) A to ensure that an Emergency Action Plan (EAP) is prepared and regularly updated. With its location along the Hillsborough River and its significant hazard potential, it is essential for stakeholders to prioritize risk management measures and follow guidelines to mitigate potential risks associated with this dam.

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.
