About William Ory Dam
The primary purpose of William Ory 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 William Ory (private). It impounds the Trib To Bulger Creek near Desoto.
The dam stands 31 feet tall and stretches 440 feet across, creates a reservoir covering 2 acres, has a maximum storage capacity of 33 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2018, 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.
