Located in the Upper Verdigris Watershed in Kansas, Frd No 9-4, also known as the Upper Verdigris Watershed Dam 9-4, is a crucial structure designed by the USDA NRCS to mitigate flood risks in the area. Completed in 1964, this earth dam stands at a height of 27 feet and has a hydraulic height of 24 feet, offering flood risk reduction for the Halderman Creek-TR stream. With a storage capacity of 848.35 acre-feet and a normal storage capacity of 65 acre-feet, Frd No 9-4 plays a vital role in protecting the surrounding community.

The dam, with a length of 1350 feet and a surface area of 13.43 acres, is regulated by the Kansas Department of Agriculture and undergoes regular inspections to ensure its structural integrity. Despite being classified as having a low hazard potential, the dam is rated as moderately risky due to its age and the potential impact of a failure. The presence of an uncontrolled spillway with a width of 40 feet adds to the dam's risk factor, highlighting the importance of ongoing risk management measures to safeguard the area from potential disasters.

While Frd No 9-4 currently does not have an emergency action plan in place, its risk assessment and condition are regularly evaluated to ensure the safety of the surrounding communities. With its strategic location in the Greenwood County of Kansas, this dam serves as a critical infrastructure for flood control and water resource management in the region, emphasizing the essential role it plays in maintaining the resilience of the local ecosystem in the face of changing climate conditions.
