Water
Watershed condition is integral to all aspects of resource management and use. Good watersheed management maintains the productive capacity of soils, protects water quality and quantity, sustains native species, provides beneficial uses, and reduces the threat of flood damage to Forest Service infrastructure and downstream values.  Most of the Shoshone is within the upper Missouri River Basin, subdivided by the Wind/Big Horn and Clarks Fork of the Yellowstone River basins. The southern tip of the Shoshone is in the Sweetwater drainage, which flows into the Platte River system.  Principal rivers within the Shoshone's boundary are the Clarks Fork of the Yellowstone River, North and South Forks of the Shoshone River, and the Greybull, Wind/Big Horn, and Popo Agie Rivers.

Air
Federal land managers manage air quality as directed by the Clean Air Act and the Wilderness Act. On the Shoshone, the Fitzpatrick, Washakie, and North Absaroka Wilderness areas are Class I airsheds wehre no deterioration of air quality is allowed. All other areas on the Shoshone are Class II airsheds, where air quality must meet standards set by the Wyoming Department of Environmental Quality.
