About Cook Dam
The primary purpose of 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 Larry Cook (private). It impounds the West Locust Creek near Reger.
The dam stands 27 feet tall and stretches 456 feet across, creates a reservoir covering 6 acres, has a maximum storage capacity of 63 acre-feet, and collects water from a drainage area of 192 square miles. Completed in 1995, the structure is 31 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.
