Values given for Climatic Zones 5 and 6, which cover the study area, were <br /> <br /> <br />interpolated based on elevation for the Norwood and Redvale areas for alfalfa, spring grains, <br /> <br /> <br />and grass hay/pasture. The .Colorado Irrigation Guide" also indicated late season (October) <br /> <br /> <br />gross crop consumptive use values for these crops. Estimates for October were included for <br /> <br /> <br />consistency and were made using the same interpolation procedure described above for April. <br /> <br /> <br />The April and October gross crop consumptive use values estimated for these crops for <br /> <br /> <br />Norwood and Redvale are shown in Tables 1 and 2, respectively. <br /> <br />A portion of the water required by a crop is typically supplied by precipitation. The portion of <br /> <br /> <br />the precipitation which falls on a crop which can be used to satisfy some or all of the <br /> <br /> <br />consumptive use requirements is called effective precipitation.
