Duck is a privately owned dam located in Yuma, Colorado, along the Arikaree River. Completed in 1954, Duck serves primarily for irrigation purposes, with a storage capacity of 56 acre-feet and a surface area of 5 acres. The dam stands at 18 feet in height and spans 450 feet in length, with a maximum discharge of 1100 cubic feet per second.

Despite its low hazard potential, Duck has been assessed as unsatisfactory in condition, with the last inspection conducted in May 2011. The dam features an uncontrolled spillway and is regulated by the Colorado Division of Water Resources, with state permitting, inspection, and enforcement in place. Risk assessment indicates a moderate level (3) of risk associated with Duck, prompting the need for continued monitoring and potential risk management measures in the future. For water resource and climate enthusiasts, Duck presents an intriguing case study in the management and maintenance of small dams for agricultural purposes in a changing climate.
