Dondlinger Dam, located in Fairbury, Nebraska, is a privately owned structure designed by the USDA NRCS and regulated by the Nebraska Department of Natural Resources. Completed in 1964, this earth dam stands at a height of 20 feet and serves primarily for flood risk reduction along the Little Blue River. With a storage capacity of 154 acre-feet and a drainage area of 0.7 square miles, the dam plays a crucial role in managing water flow and mitigating potential flooding in the region.

Despite its low hazard potential, Dondlinger Dam has been assessed to be in poor condition as of April 2017. The dam's inspection frequency is set at every 5 years, with the last inspection date recorded in April 2017. While emergency action plans and risk assessments are yet to be fully detailed, the dam continues to be monitored and maintained to ensure its structural integrity and effectiveness in flood control. As a key infrastructure in Thayer County, Nebraska, Dondlinger Dam stands as a testament to the collaborative efforts between private owners and regulatory agencies in safeguarding water resources and communities against potential hazards.
