Green Cabin No. 3, nestled in the picturesque Sheridan, Wyoming, is a privately-owned earth dam with a primary purpose of fire protection, stock, or a small fish pond. Built in 1969, this dam stands at 31 feet tall with a hydraulic height of 22 feet and a structural height of 31 feet, providing a storage capacity of 75 acre-feet. The dam spans 250 feet in length and covers a surface area of 3 acres, serving as a vital resource for the surrounding area.

Despite its low hazard potential and fair condition assessment, Green Cabin No. 3 undergoes regular inspections, with the last one conducted in July 2017. Its uncontrolled spillway, with a width of 35 feet, ensures proper water discharge during periods of excess flow. This dam plays a crucial role in mitigating the risk of flooding and provides essential water resources for fire protection, livestock, and small-scale fisheries in the region.

Located in the Green Cabin Draw and managed by the private owner in Clearmont, Wyoming, Green Cabin No. 3 stands as a testament to sustainable water resource management and the intersection of infrastructure with environmental conservation. Its significance lies not only in its functional purposes but also in its contribution to the local ecosystem and climate resilience efforts in the area.
