Wayne Hansen Dam, located in Saline County, Nebraska, is a privately owned structure designed by the USDA NRCS and regulated by the Nebraska Department of Natural Resources. Completed in 1999, this earth dam stands at a height of 25 feet with a hydraulic height of 22 feet, serving primarily for flood risk reduction along the TR-Turkey Creek. With a storage capacity of 180 acre-feet, it covers a surface area of 6 acres and drains a 1.3 square mile watershed.

Despite its low hazard potential and satisfactory condition assessment as of 2017, Wayne Hansen Dam undergoes regular inspections every 5 years to ensure its structural integrity. The dam's emergency action plan status, risk assessment, and management measures are currently undisclosed, suggesting a need for further risk evaluation and preparedness. With Congressman Adrian Smith representing the area, the dam plays a crucial role in mitigating flood risks for the community of Dewitt and the surrounding region, showcasing the importance of water resource management and climate resilience efforts in the face of changing environmental conditions.
