Dd No 5-1, located in Hodgeman County, Kansas, is a vital infrastructure designed by Agricultural Eng. Assoc. for flood risk reduction along Cottonwood Creek. Completed in 1995, this earth dam stands at a height of 33 feet and spans 2415 feet, providing a storage capacity of 2770.59 acre-feet for debris control and flood risk mitigation. Despite its low hazard potential, the dam's condition remains unrated as of the last inspection in 2011.

The dam features an uncontrolled spillway with a width of 200 feet, capable of discharging up to 6360 cubic feet per second during peak flow events. With a moderate risk assessment rating, Dd No 5-1 falls under the jurisdiction of the Kansas Dept. of Agriculture for permitting, inspection, and enforcement. While the dam has not been modified in recent years and lacks outlet gates, it plays a crucial role in protecting the surrounding area from potential flooding, emphasizing the importance of continued monitoring and risk management practices to ensure its effectiveness in the face of changing climate conditions.
