Prairie, also known as Bargum, is a private-owned irrigation dam located in Fremont, Wyoming. Completed in 1915, this earth dam stands at a height of 17 feet and spans a length of 1840 feet, with a storage capacity of 771 acre-feet. Situated on Dry Muddy Creek, Prairie serves the primary purpose of irrigation and is regulated by the State of Wyoming.

Despite its age, Prairie has a low hazard potential but is currently assessed to be in poor condition. The dam features an uncontrolled spillway, with a spillway width of 40 feet and one valve outlet gate. Its location in a moderate risk area underscores the importance of regular inspections and maintenance to ensure its structural integrity and safeguard against potential risks to downstream communities and ecosystems. It is crucial for water resource and climate enthusiasts to track the condition and management of dams like Prairie to mitigate potential hazards and ensure the sustainable use of water resources in the region.
