Asimus Dam, located in Holt, Nebraska, is a privately owned structure designed by the USDA NRCS for irrigation purposes on the TR-NIOBRARA RIVER. Completed in 1962, this earth dam stands at a height of 31 feet with a hydraulic height of 30 feet, serving a drainage area of 2.9 square miles. With a storage capacity of 84 acre-feet, it covers a surface area of 7 acres and has a maximum discharge rate of 298 cubic feet per second.

Despite being regulated by the NE DNR and regularly inspected, Asimus Dam is assessed to be in poor condition with a low hazard potential. The last inspection in April 2018 revealed this assessment, and the structure has been deemed to require attention for maintenance and upgrades. Although the dam has not undergone modifications in recent years, its functionality for irrigation purposes remains critical for the local agricultural community. Enthusiasts of water resources and climate change will find the history and current status of Asimus Dam to be a compelling case study in managing and maintaining essential infrastructure in the face of evolving environmental challenges.
