Allard Dam
Allard Dam is an earth dam located in Macon County, Missouri, built in 1997. It carries a Low hazard potential classification.
About Allard Dam
The primary purpose of Allard 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 Gail Allard (private). It impounds the Painter Creek near New Cambria.
The dam stands 37 feet tall and stretches 398 feet across, creates a reservoir covering 6 acres, has a maximum storage capacity of 50 acre-feet, and collects water from a drainage area of 268 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.
At 37 feet, this dam is taller than 84% of dams nationwide.
