About Cerva Dam
The primary purpose of Cerva 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 Jim Cerva (private). It impounds the Tr-chariton River near Ardmore.
The dam stands 26 feet tall and stretches 310 feet across, creates a reservoir covering 11 acres, has a maximum storage capacity of 40 acre-feet, and collects water from a drainage area of 179 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.
