Tallman Dam
Tallman Dam is an earth dam located in Schuyler County, Missouri, built in 1990. 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 Eldon Tallman (private). It impounds the Tr-north Fabius River near Memphis.
The dam stands 29 feet tall and stretches 397 feet across, creates a reservoir covering 11 acres, has a maximum storage capacity of 92 acre-feet, and collects water from a drainage area of 465 square miles. Completed in 1990, the structure is 36 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.
