Summary

Standing at a height of 27 feet and a length of 1000 feet, the dam holds a maximum storage capacity of 1250 acre-feet and covers a surface area of 206 acres. It is situated on Hurricane Creek and falls under the jurisdiction of NWFWMD for state regulation, permitting, inspection, and enforcement.

The dam features an uncontrolled spillway with a width of 36 feet and outlet gates that are also uncontrolled. Despite being rated with a high hazard potential, the dam's condition assessment as of May 2014 was reported as satisfactory. The risk assessment for Tallavana Dam is moderate, with a DSAC (Dam Safety Action Classification) of 3, indicating a need for ongoing risk management measures to ensure the safety and integrity of the structure.

Water resource and climate enthusiasts interested in Tallavana Dam can appreciate its recreational significance, as well as the engineering complexities involved in its design and operation. With a focus on fire protection, stock, and small fish pond management, the dam serves as a vital resource for the local community while requiring diligent oversight to mitigate potential risks associated with its high hazard potential.

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.
