About Williams Dam
The primary purpose of Williams 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 Paul Williams (private). It impounds the Llittle Walnut Creek near Nind.
The dam stands 26 feet tall and stretches 300 feet across, creates a reservoir covering 13 acres, has a maximum storage capacity of 22 acre-feet, and collects water from a drainage area of 774 square miles. Completed in 1998, the structure is 28 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.
