About Walter Smith Dam
The primary purpose of Walter 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 Walter Smith (private). It impounds the Tr-mussel Fork near New Boston.
The dam stands 30 feet tall and stretches 200 feet across, creates a reservoir covering 5 acres, has a maximum storage capacity of 25 acre-feet, and collects water from a drainage area of 590 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.
