Dux Dam, located in Endicott, Nebraska, is a privately owned earth dam constructed in 1968 by USDA NRCS. Its primary purpose is flood risk reduction, serving as a critical infrastructure on TR-Buckley Creek. The dam stands at a height of 17 feet with a hydraulic height of 15 feet and a length of 420 feet, providing a storage capacity of 62 acre-feet and a normal storage of 24 acre-feet for the surrounding area.

Managed by the Nebraska Department of Natural Resources, Dux Dam is regulated, inspected, and enforced by state authorities to ensure its structural integrity and safety. The dam has a low hazard potential and has not been rated for its condition as of the last inspection in April 2018. Despite its low-risk profile, the dam plays a crucial role in managing water resources and mitigating flood risks in the region.

With its location in Jefferson County, Dux Dam contributes to the overall water management strategy in the area, covering a drainage area of 0.6 square miles and capable of discharging up to 319 cubic feet per second. While the dam has not been modified in recent years and lacks detailed risk assessment measures, it remains a key component in the local water infrastructure system, highlighting the importance of ongoing monitoring and maintenance to ensure its continued functionality and safety for the community.
