Snafu, also known as Middle Sand Coulee, is a federal-owned dam located in Park County, Wyoming, near Belfry, Montana. Built in 1967, this earth dam stands at a height of 40 feet and serves multiple purposes including water supply, recreation, and other activities. The dam holds a storage capacity of 48 acre-feet and is regulated by the State Engineer's Office in Wyoming.

Despite its low hazard potential, Snafu has been assessed to be in poor condition, with a moderate risk level. The dam has a history of poor maintenance and its last inspection in June 2019 revealed deficiencies that need attention. With a drainage area and maximum discharge capacity of 289 cfs, the dam poses a potential risk that requires proper risk management measures to be implemented.

For water resource and climate enthusiasts, Snafu provides an intriguing case study of a federally-owned dam in need of maintenance and risk assessment. With its location along the Big Sand Coulee Creek and the surrounding recreational and water supply uses, the future of Snafu's structural integrity and safety measures will be of interest to those passionate about water resource management and climate resilience.
