Summary
The dam, primarily constructed for purposes other than flood control or water supply, stands at a height of 8 feet with a hydraulic height of 5 feet. With a storage capacity of 242 acre-feet and a surface area of 25 acres, this Earth dam on the tributary of Hillsborough River plays a crucial role in the local water management system.
Despite its moderate risk assessment rating, Zephyrhills Airport dam has not been modified in recent years and is maintained by the state regulatory agency, FDEP. The spillway of the dam is uncontrolled, with a width of 13 feet, and no outlet gates are present. The last inspection of the structure took place in May 2016, indicating a diligent approach to monitoring and maintaining the dam's integrity. With its strategic location and significance in the local water distribution network, Zephyrhills Airport serves as a key asset in ensuring water resource sustainability in the region.
As climate change continues to impact water resources and infrastructure, the role of structures like Zephyrhills Airport becomes increasingly vital. With its moderate risk assessment and fair condition, ongoing monitoring and maintenance are crucial to ensure the long-term effectiveness and safety of this water resource facility. As water resource and climate enthusiasts, understanding the critical functions and challenges faced by structures like Zephyrhills Airport can deepen our appreciation for the intricate balance between human development and environmental conservation in the face of a changing climate.

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.
