Hagerman Dam, located in Hulett, Wyoming, serves as a crucial irrigation source along Arch Creek. Constructed in 1942, this private-owned earth dam stands at a height of 20 feet with a hydraulic height of 15 feet. With a storage capacity of 737 acre-feet, Hagerman Dam primarily supports irrigation purposes, with a normal storage level of 420 acre-feet and a surface area of 55 acres.

Despite its low hazard potential and fair condition assessment, Hagerman Dam undergoes regular inspections every five years to ensure its structural integrity and safety. With a spillway width of 50 feet and an uncontrolled spillway type, the dam is equipped with a single valve outlet gate for water release. While the risk assessment for the dam is moderate, there is currently no emergency action plan in place, raising the importance of preparedness and risk management measures for potential incidents.

As a vital water resource infrastructure in Crook County, Hagerman Dam plays a significant role in supporting agricultural activities in the region. With its historical significance dating back to the early 20th century, the dam continues to contribute to the local economy and water management efforts. As water resource and climate enthusiasts, it is essential to monitor and maintain the safety of dams like Hagerman to ensure sustainable water usage and environmental conservation in the face of changing climate conditions.
