About Wilcox Dam
The primary purpose of Wilcox 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 Robert R. Wilcox (private). It impounds the Tr-owl Creek near Smithville.
The dam stands 34 feet tall and stretches 410 feet across, creates a reservoir covering 11 acres, has a maximum storage capacity of 21 acre-feet, and collects water from a drainage area of 180 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.
At 34 feet, this dam is taller than 78% of dams nationwide.
