About G-87
The primary purpose of G-87 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 C-11s Canal near Sunshine Ranches.
The dam stands 17 feet tall and stretches 175 feet across, creates a reservoir covering 23 acres, has a maximum storage capacity of 300 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1952, the structure is well into its service life at over 50 years old.
This dam has a low hazard potential classification, meaning that failure would cause minimal damage, limited primarily to the dam owner's property, with no expected loss of life. The most recent inspection on record was 07/12/1905. That was over 121 years ago.
