About Sandy Hollow Dam
The primary purpose of Sandy Hollow Dam is hydroelectric. The dam generates hydroelectric power by channeling water through turbines, converting the energy of flowing water into electricity. The dam is owned by Sandy Hollow Power Co. Inc. (private). It impounds the Indian River.
The dam stands 16 feet tall and stretches 106 feet across, creates a reservoir covering 1 acres, has a maximum storage capacity of 13 acre-feet, and collects water from a drainage area of 233 square miles. Completed in 1986, the structure is 40 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 08/04/1999. That was over 26 years ago.
