Summary
Completed in 1965, this earth dam stands at a height of 10 feet and has a length of 200 feet, with a storage capacity of 59 acre-feet. Situated along Gum Creek in the STEEP HOLLOW HILL area, Thomas Dam plays a vital role in providing water resources for agricultural activities in the region.
Managed by the state of Florida, Thomas Dam is regulated, permitted, inspected, and enforced to ensure its safety and functionality. Despite being classified as having a low hazard potential, the dam's condition has not been rated, and its last inspection dates back to May 1994. While it currently meets the required guidelines, there is no information available regarding emergency action plans, risk assessments, or inundation maps, highlighting the need for updated risk management measures and emergency preparedness.
Water resource and climate enthusiasts interested in the maintenance and operation of dams like Thomas Dam will find this data-rich summary informative. With its historical significance and crucial role in irrigation, Thomas Dam serves as a focal point for understanding the importance of water infrastructure in sustaining agricultural activities and managing water resources in the region. Further research and updates on the dam's condition and risk management measures are necessary to ensure its continued safety and efficiency in the face of changing climate patterns and environmental challenges.

Dam Data Reference
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.
