6.0 PROJECTIONS
Table 6-15 presents the current and projected future water demands for each of the seven river
basin planning areas and a total for the state for all sectors. These projections are presented by future
scenario. The table presents both surface water and groundwater demands (demands presented in Table
6-15 may be compared to legally available flows as shown in Table 7–2).

In the Bear River Basin study, a Mid Scenario was not completed for agriculture. Includes agriculture estimate.

Wind/Bighorn River Basin industrial use and projections are based on water rights rather than actual consumption. This tends to over state oil and gas industry use
as well as other uses.
