About Kelly Dam
The primary purpose of Kelly 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 Kelley Church (private). It impounds the Nick Branch near Adair.
The dam stands 30 feet tall and stretches 474 feet across, creates a reservoir covering 6 acres, has a maximum storage capacity of 47 acre-feet, and collects water from a drainage area of 325 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.
