Black Butte, located in Sublette, Wyoming, is a privately owned earth dam completed in 1989 for purposes such as fire protection, stock, and small fish pond. The dam stands at a height of 25 feet and has a storage capacity of 236 acre-feet, with a maximum discharge of 114 cubic feet per second. The primary source agency for Black Butte is the Wyoming state regulatory agency, which oversees permitting, inspection, and enforcement to ensure compliance with state regulations.

Despite being classified as having a low hazard potential, Black Butte is currently in poor condition as assessed in October 2017. With an inspection frequency of 5 years, the dam poses a moderate risk, warranting attention to ensure its structural integrity and safety. The spillway type is uncontrolled, with one uncontrolled outlet gate and a spillway width of 12 feet. As a vital resource for fire protection and wildlife conservation, Black Butte serves as a reminder of the importance of responsible water resource management in the face of changing climates and increasing demands.
