Tallman Dam
Tallman Dam is an earth dam located in Schuyler County, Missouri, built in 1997. It carries a Low hazard potential classification.
About Tallman Dam
The primary purpose of Tallman 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 Curtis Tallman (private). It impounds the North Fabius near Bunker Hill.
The dam stands 33 feet tall and stretches 220 feet across, creates a reservoir covering 4 acres, has a maximum storage capacity of 16 acre-feet, and collects water from a drainage area of 270 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 33 feet, this dam is taller than 78% of dams nationwide.
