Heusman Dam, located in Johnson County, Nebraska, is a privately owned structure with a primary purpose of flood risk reduction. Built in 1960 by the USDA NRCS, this earth dam stands at 26 feet high and stretches 411 feet in length. It has a storage capacity of 68 acre-feet, with a normal storage level of 23 acre-feet, covering a surface area of 4 acres and draining a 0.83 square mile watershed.

Despite its low hazard potential, Heusman Dam has been assessed as being in poor condition as of May 2017. The dam is regulated, permitted, inspected, and enforced by the Nebraska Department of Natural Resources, ensuring its compliance with state regulations. The dam's emergency action plan status and risk management measures are currently unknown, suggesting potential areas for improvement in the future.

Water resource and climate enthusiasts may find Heusman Dam an interesting case study for its design, construction, and management by the USDA NRCS. With its important role in flood risk reduction along the TR-N FK Big Nemaha River, this dam serves as a vital infrastructure in protecting the surrounding community from potential water-related disasters. The dam's condition assessment and risk management practices offer valuable insights into the ongoing efforts to maintain and improve water infrastructure in Nebraska.
