Show PART VII COMPARISONS AND CONCLUSIONS will receive supplemental water in connection with new land development, except for the 1968 OBERS alternative. It is assumed in the 1968 OBERS level that agricultural activity will increase only by importing feed and feeder calves for projected feedlot operations. Timber production under on-going programs will increase about 5 per- cent in each time frame of the projected period. The 1968 OBERS timber production shows an increase of four times the present production by 2020. For the framework plan and the three states' alternatives, production will increase about sevenfold over the present. Livestock grazing production under on-going programs is estimated to increase only 0.3 million AUM's by 2020. The 1968 OBERS projections would require a reduction in going programs with a resultant waste of the resource. The framework plan shows an increase of 1.3 million AUM's. Op- timum grazing production would provide an increase of over 2 million AUM's. This production is available as an alternative for the framework plan and the three states' alternatives. In Table 23 it is shown only under the "water at site" level of development, because grazing is not affected by the alternative water supplies analyzed under the other two states' alter- natives. Industrial activity Two significant sectors of industrial activity in the region are production of minerals and thermal-electric power. Thermal-electric power capacity installed to supply local use and for export would increase from the present 1,300 to Vf,600 megawatts at the highest level of develop- ment. Mineral activity planned for the states' alternative levels includes four shale oil plants with a total capacity of k million barrels-per-day. Coal conversion by hydrogenation is planned. This, together with coal mined for thermal-power production, approximates 200 million tons annually. Uranium production will increase significantly. Trona production in Wyo- ming is projected to increase to four times the present level. Fish and wildlife - recreation Present sport hunting and fishing demand is projected to nearly double by 2020 under both the on-going and the framework plan. Alterna- tive plans are based upon projected population changes. Recreation de- mand, 97 percent by nonresidents, will increase fourfold. Watershed management Watershed management is planned to reduce the average annual dama-ges by about 50 percent from man-created watershed problems and about 10 per- cent relative to natural problems. This program also includes improving water yield in terms of quantity, quality, and timing as a result of vege- tal manipulation. The going program will accomplish about kO percent of the framework plan. 99 |
