About Clema Dam
The primary purpose of Clema 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 Joe Clema (private). It impounds the Middle Fork Salt River near Macon.
The dam stands 30 feet tall and stretches 355 feet across, creates a reservoir covering 7 acres, has a maximum storage capacity of 40 acre-feet, and collects water from a drainage area of 243 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.
