Show PARE IV FUTURE DEMAND Projections of Demand for Irrigated Land The irrigated acreages by crops for 1965 are presented in Part II under the heading "Contribution of Irrigation to Region's Economy." The acreages of various crops required to meet OBERS projections for 1980, 2000, and 2020 for the three subregions in the Upper Colorado Region are shown in Tables 23,,2.H, and 25 and illustrated below. IRRIGATED ACREAGE AND PROJECTED REQUIREMENTS 1965-2020 BY HYDROLOGIC REGION AND SUBREGION ? REGION GREEN RIVER SUBREGION UPPER MAIN STEM SUBREGION SAN JUAN-COLORADO SUBREGION YEARS Total acreages of irrigated cropland needed to meet the economic de- mands of the region were projected to increase from 1,621,500 to 2,122,100 acres, or by 500*600 acres, during the period 1965 to 2020. An additional 86,800 acres of potentially irrigable land will be needed to replace presently irrigated land expected to be abandoned or converted to urban- ization, reservoir inundation, recreation, and interstate highway right- of-way. Anticipated losses are shown in Table 26. THOUSAND ACRES |
