The facilities included in the initial stage for irri- gation are designed to provide water for both supplemental and new irrigation for approxi- mately the following areas: Area supplied with water Supplemental New Projects under construction.....

In addition 188,000 kilowatts are under construction by local private and public agencies, 234,000 kilowatts are in authorized Federal projects. Although the fore- going installations would provide over 1 million kilowatts of additional capacity, it has been esti- mated that the power load in the region will require more than 3 million kilowatts in new capacity dur- ing the next 20 years. It will therefore be necessary during the initial stage to provide approximately 2 million kilowatts of capacity in addition to that included in the specific projects listed above. This additional capacity could be obtained partially from fuel- electric plants and partially from hydroelectric plants, both single-purpose and multiple-purpose. The undeveloped hydroelectric power possibilities that would be available for both the initial and long- range needs are estimated to be some 4.6 million kilowatts capacity, with potential annual generation of 22.5 billion kilowatt-hours. Further studies will be required for selection of the more favorable of these for early construction. Operation of reservoirs included in the initial stage for flood control and related channel improve- ments would provide increased flood control for more than 40 existing urban areas and almost 2 million acres of rural land. The improvement of watershed conditions is an important element of the initial stage of develop- ment in Central Valley. On forest lands this calls for, among other things, an intensified fire control program, reforestation of denuded areas, construc- tion of access roads, and public acquisition of forest lands that cannot be properly managed under private ownership. The proper stocking and rehabilitation of eroding range lands should be ac- complished in the initial stages of basin develop- ment. The stabilization of upstream drainage ways and small tributaries by structures and vege- tative plantings is needed. At the present rate of adoption of conservation practices on cultivated lands, it will be more than a century before the productivity of these lands will be stabilized. In the meantime great loss of soil resources will have occurred. The adoption of conservation practices on croplands needs to be in- 911610-51- -12 155 Organization |
