About Rex Gray Dam
The primary purpose of Rex Gray Dam is grade stabilization. Grade stabilization dams prevent erosion by reducing the slope and velocity of water flowing through a channel. They're commonly used to stop gullies from deepening and to protect downstream land and infrastructure. The dam is owned by Rex Gray (private). It impounds the Tr-honey near Chillicothe.
The dam stands 28 feet tall and stretches 441 feet across, creates a reservoir covering 3 acres, has a maximum storage capacity of 44 acre-feet, and collects water from a drainage area of 44 square miles. Completed in 1995, the structure is 31 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 08/24/1996. That was over 29 years ago.
