About White Dam
The primary purpose of White 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 Mark White (private). It impounds the Middle Fork Salt River near Macon.
The dam stands 25 feet tall and stretches 477 feet across, creates a reservoir covering 9 acres, has a maximum storage capacity of 29 acre-feet, and collects water from a drainage area of 150 square miles. Completed in 1998, the structure is 28 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.
