Wiley is a privately owned irrigation dam located in Park County, Wyoming, near the city of Byron. Built in 1971 by designer Lee Graham, this earth dam on Sage Creek stands at a height of 31 feet and has a storage capacity of 1365 acre-feet. Despite its low hazard potential, the dam is currently in poor condition, as per the last inspection in June 2019.

With a surface area of 331 acres and a drainage area of zero, Wiley serves primarily for irrigation purposes. Its spillway type is uncontrolled, with a width of 6 feet. Although the dam has not been modified in recent years, it is subject to regular state regulation, inspection, and enforcement. Its location in a congressional district represented by Liz Cheney underscores its importance in the water resource management of the region.

While Wiley may have a moderate risk assessment, its role in supporting agriculture and water supply in the area cannot be overlooked. As a key structure on Sage Creek, it highlights the intersection of water resource management and climate resilience. With its historical significance and ongoing regulatory oversight, Wiley continues to be a focal point for water resource and climate enthusiasts interested in sustainable infrastructure development.
