Garnett is a privately owned earth dam located in Big Horn, Wyoming, near the city of Greybull. Completed in 1944, this dam serves primarily for irrigation purposes along the Shell Creek tributary of the Bighorn River. With a height of 30 feet and a storage capacity of 185 acre-feet, Garnett covers a surface area of 16 acres and has a drainage area of 0.4 square miles.

Despite its historical significance, Garnett is facing significant hazard potential due to its poor condition assessment, as reported in the last inspection conducted in May 2021. The dam's spillway type is uncontrolled, with a width of 12 feet, and it features a single valve as an outlet gate. The risk assessment for Garnett is moderate, emphasizing the need for proper risk management measures to mitigate any potential threats to the surrounding area and the dam's structural integrity.

Given its location and purpose, Garnett plays a crucial role in water resource management and irrigation practices in the region. With its proximity to the Bighorn River and surrounding agricultural lands, ensuring the safety and functionality of Garnett is vital for both water users and the local ecosystem. As climate change continues to impact water resources, maintaining and improving the infrastructure of dams like Garnett is essential for adapting to changing conditions and ensuring sustainable water management practices in the future.
