About Stevenson Dam
The primary purpose of Stevenson 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 Stevenson Farms (private). It impounds the Burnt Shirt Branch near Chambersburg.
The dam stands 29 feet tall and stretches 365 feet across, creates a reservoir covering 4 acres, has a maximum storage capacity of 27 acre-feet, and collects water from a drainage area of 82 square miles. Completed in 1997, the structure is 29 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.
