Summary
Constructed in 1970, this dam stands at a height of 100 feet, with a hydraulic height of 80 feet and a structural height of 110 feet. It has a maximum storage capacity of 3400 acre-feet and a normal storage capacity of 3000 acre-feet, serving the purpose of tailings storage. The dam spans a length of 11200 feet and covers a surface area of 50 acres.
The dam is situated on the Hillsborough River and is regulated by the Florida Department of Environmental Protection (FDEP). It is classified as having a significant hazard potential, with a very high risk assessment rating. The spillway type for Temple Terrace Cell D is controlled, with a spillway width of 16 feet. Despite its condition being listed as "Not Rated," the dam is subject to regular state inspection, permitting, and enforcement to ensure its safety and integrity. With its strategic location and crucial role in water resource management, Temple Terrace Cell D represents a key infrastructure for climate and water resource enthusiasts to monitor and study.

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.
