About S-30
The primary purpose of S-30 is flood risk reduction. The dam is designed to control downstream flooding by temporarily storing excess water during storms and releasing it at a controlled rate. The dam is owned by Sfwmd (local government). It impounds the Snake Creek Canal (c-9) near Miramar.
The dam stands 14 feet tall and stretches 60 feet across, creates a reservoir covering 21 acres, and has a maximum storage capacity of 292 acre-feet. Completed in 1960, the structure is well into its service life at over 50 years old.
This dam has a significant hazard potential classification, meaning that a failure could cause significant economic damage — flooding roads, bridges, or property downstream — but is not expected to result in loss of life. The most recent inspection on record was 07/12/1905. That was over 121 years ago.
