About Harry Mullock Dam
The primary purpose of Harry Mullock 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 Harry Mullock (private). It impounds the Tr-"x" Branch near Darlington.
The dam stands 30 feet tall and stretches 200 feet across, creates a reservoir covering 13 acres, has a maximum storage capacity of 39 acre-feet, and collects water from a drainage area of 174 square miles. Completed in 1991, the structure is 35 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.
