About Gibbs Avenue Dam
The primary purpose of Gibbs Avenue Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Disputed. It impounds the Tr-st. Johns River near Saratoga Harbor Estates.
The dam stands 19 feet tall and stretches 280 feet across, creates a reservoir covering 4 acres, and has a maximum storage capacity of 108 acre-feet. Completed in 1960, the structure is well into its service life at over 50 years old.
This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. Its condition is rated satisfactory, indicating no existing or potential dam safety deficiencies are recognized. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 08/01/2014. That was 11 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
