  1. Includes reservoir evaporation as a use.
  2. In the Bear River Basin study, a Mid Scenario was not completed for agriculture. Includes agriculture estimate.
  3. Wind/Bighorn River Basin industrial use and projections are based on water rights rather than actual consumption. This tends to overstate oil and gas industry use as well as other uses.
