They're commonly used to stop gullies from deepening and to protect downstream land and infrastructure. The dam is owned by Upland Investments (private). It impounds the Tr-possum Creek near Nebraska City.
The dam stands 23 feet tall and stretches 441 feet across, creates a reservoir covering 9 acres, has a maximum storage capacity of 140 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2021, the structure is relatively new.
