Hall Dam, located in Morrill, Nebraska, is a privately owned structure designed by USDA NRCS to serve the primary purpose of flood risk reduction. Completed in 1970, this earth dam stands at a height of 33 feet with a hydraulic height matching the structural height of 35 feet, and a length of 403 feet. The dam has a storage capacity of 151 acre-feet, with a normal storage level of 13 acre-feet, covering a surface area of 5 acres and draining an area of 1 square mile.

Despite its significant hazard potential, Hall Dam is currently assessed to be in poor condition based on its last inspection in October 2020. The dam is regulated by the Nebraska Department of Natural Resources and undergoes regular state inspections, enforcement, and permitting processes. With a history of modifications and no associated structures, the dam poses a risk that is yet to be fully assessed and managed, highlighting the importance of ongoing monitoring and maintenance to ensure the safety and integrity of this essential flood control infrastructure in the region.
