Floyd is a privately owned earth dam in Campbell County, Wyoming, with a primary purpose of irrigation. Built in 1950 by designer Hugh Lowham, the dam stands at 25 feet high and spans a length of 1063 feet along Prairie Dog Creek. It has a storage capacity of 94 acre-feet and serves multiple purposes including fire protection, stock watering, and small fish ponds.

Despite its low hazard potential and fair condition assessment, Floyd's risk level is moderate. The dam has an uncontrolled spillway with a width of 185 feet and an outlet gate with a single valve. Located in an unnamed ranch in Wyoming, Floyd's emergency action plan status and inundation maps are currently unknown. The last inspection in 2018 showed that the dam was meeting regulatory standards, but its risk management measures and risk characterization are unspecified.

For water resource and climate enthusiasts, Floyd presents an intriguing case study of a mid-century earth dam serving diverse agricultural needs in a rural setting. With its location in the Omaha District and proximity to Congressional District 00 in Wyoming, the dam's historical significance and ongoing regulatory oversight offer valuable insights into the intersection of water management, infrastructure resilience, and environmental stewardship. As Floyd continues to fulfill its role in sustaining local water resources, monitoring its risk profile and emergency preparedness will be critical for ensuring the long-term safety and sustainability of this vital irrigation structure.
