Abstract: Measurements to define agricultural water consumption have been taken in the Green River Basin of Wyoming throughout the summers of 1983 and 1984. The weekly measurements included water use from 14 lysimeters consisting of eight with mountain meadow vegetation, three with alfalfa and three with alta fescue as a reference crop. In addition, pan evaporation was taken at three of the lysimeter sites. Water use for both alfalfa and mountain meadows exceeded or was near pan evaporation at all sites having pan data. Seasonal consumptive use and water use efficiencies are given for sites throughout the Basin.
