About Smith Dam
The primary purpose of Smith 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 Vince Smith (private). It impounds the Tr- Indian Creek near Coppock.
The dam stands 26 feet tall and stretches 320 feet across, creates a reservoir covering 3 acres, has a maximum storage capacity of 36 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2000, the structure is 26 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.
