The largest non-Futures Projects irrigable land groups are the Westside Irrigation Project in the
Upper Bighorn River subbasin, lands on the YU Bench in the Greybull River subbasin, and lands on the
Polecat Bench in the Shoshone and Clarks Forks subbasins. More information is contained in the river
basin plan.
Another water use by the agriculture sector is livestock water. While this use is relatively small,
it is closely associated with irrigated agriculture and the production of forage for livestock. Table 6-6
presents estimates of livestock water usage for the three scenarios.
