About Epperson Dam
The primary purpose of Epperson 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 Ralph Epperson (private). It impounds the Little Peno Creek near Spencerburg.
The dam stands 28 feet tall and stretches 465 feet across, creates a reservoir covering 7 acres, has a maximum storage capacity of 24 acre-feet, and collects water from a drainage area of 262 square miles. Completed in 1994, the structure is 32 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.
