About West Dam
The primary purpose of West 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 Dan West (private). It impounds the Long Branch near Macon.
The dam stands 25 feet tall and stretches 193 feet across, creates a reservoir covering 4 acres, has a maximum storage capacity of 27 acre-feet, and collects water from a drainage area of 110 square miles. Completed in 1996, the structure is 30 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.
