Dome Lake, located in Sheridan, Wyoming, is a privately owned irrigation dam completed in 1906 on the West Fork Big Goose Creek. With a height of 8 feet and a hydraulic height of 5 feet, this earth dam serves as a crucial water resource for the surrounding area, providing a storage capacity of 525 acre-feet and covering a surface area of 101 acres. The dam's spillway, with a width of 75 feet, is uncontrolled, and it is equipped with a single slide gate as its outlet.

Despite its age, Dome Lake's condition assessment is rated as fair, with a low hazard potential and a moderate risk assessment. The dam is inspected every five years, with the last inspection conducted in September 2020. While the risk management measures and emergency action plan status are not specified in the data, the dam is regulated by the State of Wyoming, ensuring that it meets state permitting, inspection, and enforcement requirements. Water resource and climate enthusiasts interested in the history and maintenance of irrigation dams will find Dome Lake to be an intriguing case study in water management and infrastructure resilience.
