About Norman Cook Dam
The primary purpose of Norman Cook 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 Norman Cook (private). It impounds the Chariton Creek near Chariton.
The dam stands 28 feet tall and stretches 460 feet across, creates a reservoir covering 2 acres, has a maximum storage capacity of 42 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2020, the structure is relatively new.
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.
