Cardwell, located in Carbon County, Wyoming, stands as a testament to early 20th-century engineering with its Earth-type dam constructed in 1907 for the primary purpose of irrigation. Sitting on the banks of the Little Canyon Creek, this privately owned structure boasts a height of 34 feet and a length of 370 feet, providing a surface area of 16 acres and a storage capacity of 161 acre-feet. Despite its age, Cardwell's dam continues to serve its intended function, albeit with a poor condition assessment and a moderate risk rating.

Managed by the Wyoming State Engineer's Office, Cardwell's dam is regulated, permitted, inspected, and enforced by state authorities, ensuring compliance with safety standards and emergency preparedness protocols. The dam's low hazard potential is offset by its moderate risk rating, prompting ongoing risk management measures to mitigate any potential issues. With Liz Cheney representing the area in Congress, Cardwell remains a vital part of the local irrigation infrastructure, supporting agricultural activities in the region. For water resource and climate enthusiasts, Cardwell offers a glimpse into the historical significance and ongoing maintenance of water infrastructure in Wyoming.
