About Anna Smith Dam
The primary purpose of Anna 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 Anna Smith (private). It impounds the Unnamed Trib To Buck Creek near Atlantic.
The dam stands 29 feet tall and stretches 500 feet across, creates a reservoir covering 1 acres, has a maximum storage capacity of 21 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2023, the structure is relatively new.
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.
