Show PART IV FUTURE DMAED The most significant characteristic of the acreages shown in Ta"ble 30 is that approximately four-fifths of the land required for irrigation by 2020 is now privately owned, including individual or corporate ownerships and Indian tribal or individual ownerships held in trust by the Bureau of Indian Affairs. The remaining one-fifth of the land is in Federal and State ownership, with most of it in public domain administered by the Bu- reau of Land Management for multiple uses. Ownership of these lands con- trasts with that of the total land area of the region, in which nearly two-thirds is in public ownership under Federal, State, or local adminis- tration. In developing the ^Qj.k million acres of potentially irrigable land for irrigation, consideration will be given to the pattern of ownerships and their relationship to developed lands. "Where undeveloped public lands are interspersed with privately owned irrigated lands in relatively small tracts, "they may be incorporated into existing farm units through a land sale program to private individuals. This can be done under present Bu- reau of Land Management policy and public land laws governing disposition of public domain lands. Where large noncontiguous areas of public or privately owned lands occur, these will be included in new farm units. The transfer of land from public to private ownership will require considerable planning and coordination. Under Reclamation law, for in- stance, an individual cannot receive water from a reclamation project for more than 160 acres of Class 1 land or its equivalent of Class 2, 3> and k land. The types of farm development on Indian-owned irrigable lands may include tribal corporate, development lease, individual or combina- tions of these. Land use The projected crop distribution by hydrologic subregions in the Up- per Color-ado Region is shown in Tables 23, 2k, and 25. In 1965 the pri- mary uses of irrigated cropland for hay, pasture, corn silage, and feed grains accounted for 87 percent of all irrigated lands. In 2020 these same crops are expected to account for 86 percent of all irrigated lands while other crops and idle lands are expected to account for 14 percent. The projected acreages of orchard and truck crops remain the same throughout the study period. Projected yields increased at about the same rate as projected output requirements. Both orchard and truck crops, however, account for only a minor part of the expected use of the total irrigated acreage. Crop yields and production Projections of crop yields and total production from irrigated land for I98O, 2000, and 2020 are shown by %drologic Subregions in the Upper Colorado Region in Tables 31 to 36, inclusive. |
