They're commonly used to stop gullies from deepening and to protect downstream land and infrastructure. The dam is owned by Scott Sump (private). It impounds the Trib To Nodaway River near Braddyville,.
The dam stands 29 feet tall and stretches 414 feet across, creates a reservoir covering 3 acres, has a maximum storage capacity of 33 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2013, the structure is relatively new.
