Gall Dam
Gall Dam is an earth dam located in Macon County, Missouri, built in 1994. It carries a Low hazard potential classification.
About Gall Dam
The primary purpose of Gall 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 Larry Gall (private). It impounds the Mussel Fork near New Cambria.
The dam stands 28 feet tall and stretches 225 feet across, creates a reservoir covering 8 acres, has a maximum storage capacity of 21 acre-feet, and collects water from a drainage area of 390 square miles. Completed in 1994, the structure is 32 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.
