Pratt Dam
Pratt Dam is an earth dam located in Gentry County, Missouri, built in 1989. It carries a Low hazard potential classification.
About Pratt Dam
The primary purpose of Pratt 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 Milton Pratt (private). It impounds the Tr-walnut Fork near Darlington.
The dam stands 31 feet tall and stretches 540 feet across, creates a reservoir covering 1 acres, has a maximum storage capacity of 167 acre-feet, and collects water from a drainage area of 51 square miles. Completed in 1989, the structure is 37 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.
