No full textDocument: Appendix to Pacific Southwest Water Plan of August 1963 as modified January 1964 "Bureau of Reclamation Appendix", January 1964, page 14Pumping Energy and Generation Associated with Proposed Initial Plan Facilities in California--The initial plan of development tentatively proposed in the Pacific Southwest Water Plan Report for the conservation and conveyance of 1,200,000 acre-feet of water from the North Coastal area of California to southern California will require an estimated 5,900,000,000 kilowatt-hours of energy annually for pumping under full development. At the same time, this plan of development would generate 3,540,000,000 kilowatt-hours annually from the power plants included in the plan. This leaves 2,360,000,000 kilowatt-hours annually at full development to be supplied from sources outside the plant itself. In the report it was assumed that power purchased from appropriate sources would be utilized to meet the remainder of the load required by this portion of the Pacific Southwest Water Plan in excess of that to be generated.
The following table shows the breakdown of pumping energy requirements and generation for each of the segments of the conservation and conveyance of the 1,200,000 acre-feet of water from the North Coast area of California to southern California.

Pacific Southwest Water Plan - Appendix of August 1963
No full textDocument: Appendix to Pacific Southwest Water Plan of August 1963 as modified January 1964 "Bureau of Reclamation Appendix", January 1964, page 11The reservoir storage systems and related diversions to Sacramento River proposed under this plan should be authorized for construction and operation by the Bureau of Reclamation as part of the Pacific Southwest Water Plan even though they will be integrated closely with existing and proposed features of the Federal Central Valley Project.
The east side San Joaquin Valley areas are very conscious of their existing and increasing needs for additional water. They will be alert, particularly to any plan which proposes increased exportation of water from the Central Valley Basin unless that plan also includes service to the San Joaquin Valley areas. For that purpose, therefore, in addition to the aforedescribed facilities for storing and conveying water to southern California, service also would be provided under this plan to the southern portion of the East Side Division by including incremental canal capacity of 3,000 c. f. s. in the California Aqueduct from the Delta to Wheeler Ridge. From that location a 3,000 c.f.s canal would extend to Tule River. Two off-stream storage reservoirs with a combined capacity of about 1,800,000 acre-feet and associated pumping plant facilities would be included with this proposed development. The estimated capital cost of these proposed conveyance and off-stream storage facilities for East Side Division service is estimated, on a reconnaissance basis, at 375,000,000. Costs of required distribution systems are not included These proposed facilities, through integration with the Millerton Lake system, could supply about 1,400,000 acre-feet of additional water to the east side area. Inclusion of the increased conveyance capacity for East Side Division in the California Aqueduct, if it were increased for additional conveyance to southern California, would provide the least expensive and most rapid method of providing initial service to the southern San Joaquin Valley. It is highly important that this be done if the plan for increased conveyance through the California Aqueduct were adopted
The estimated annual OM&R costs for these East Side Division facilities. exclusive of pumping energy are 1,450,000. Pumping power costs are estimated at $9,400,000 for the east side service. Subsequently early authorization of additional works would be required to provide increased East Side Division service through facilities on the east side of San Joaquin Valley from the Delta to connect at Tule River with the features proposed under this plan.
The transfer of additional water of a high quality through the Sacramento-San Joaquin River Delta will require modification of the present channels which were constructed as part of the extensive levee system to protect the low elevation Delta lands from flooding. To accomplish this the Bureau has proposed that a new channel around the periphery of

In addition, the channel will provide maximum protection to the large resident and anadromous fisheries that use the present Delta channels. The excellent quality of water will be of economic value to southern California in two ways: (1) costs of water treatment will be reduced, and (2) the low salt content of the water will permit maximum reuse.
The estimated capital cost of the Delta Peripheral Canal is 70,000,000, with an annual OM&R cost, including power, of 800,000. This facility should be authorized for Federal construction with appropriate financial participation by the State of California.
Further development of water in Central Valley Basin and increased diversions from the Delta, either for use in southern California or within the Central Valley, also expands the urgency for the Kellog Unit to offset adverse effects which may occur to water supplies relied upon by Contra Costa County. These facilities are proposed as an integral part of the Central Valley Project principally for water quality improvement, although other multiple-purpose functions would be served for the urbanized and highly industrialized Contra Costa County. This area is now being served in part by the Central Valley Project. This unit also would provide operational flexibility for the Central Valley Project through integration with operations of Tracy Pumping Plant and the Delta Peripheral Canal.
The estimated capital cost of this proposed unit is 55,000,000, with an annual OM&R cost of 285,000. In addition, an annual pumping cost of $120,000 is estimated.

Subsequently, Eltapom Reservoir, with a gross storage capacity of 3,100,000 acre-feet, would be constructed on the South Fork of Trinity River. This reservoir also would develop an annual yield of 600,000 acre-feet which would be diverted to Helena Reservoir, with subsequent diversion to Sacramento River. Power generating facilities would be incorporated with these proposed developments. Estimated capital costs of these reservoirs and associated facilites, as estimated by the State of California are 540,000,000. Annual OM&R costs would be offset by power revenues with a net annual amount remaining of about 12,300,000.
The estimated total capital cost for this prospective plan, including tunnel diversions and conveyance to southern California, exchange conveyance facilities, and storage reservoir systems is 1,750,000,000 (reconnaissance). The estimated annual OM&R and pumping costs would be offset by power revenues with a net amount remaining of about 3,900,000.
Under this proposal, therefore, the additional 1,200,000 acre-feet of water would be stored and conveyed to southern California at an estimated average annual equivalent cost of $63.00 per acre-foot, including interest at 3 percent and amortization of the facilities in 50 years.
The average annual acre-foot cost given is computed by using only the incremental costs of enlargement of conveyance facilities. Appropriate allocation of costs between the East Side Division facilities and the proposed incremental enlargement under this plan may reflect some increase in this acre-foot value.
This plan contemplates diversion of water from several east side San Joaquin Valley streams by relatively high elevation tunnels. Since this water is now being used downstream, exchange facilities and water supplies will be required. Approval of these exchanges will require negotiations with the downstream water users. Such negotiations could be both lengthy and complex.
The reservoir storage systems and related diversions to Sacramento River proposed under this plan should be authorized for construction and operation by the Bureau of Reclamation as part of the Pacific Southwest Water Plan, even though they will be integrated closely with existing and proposed features of the Federal Central Valley Project.
Associated with this development would be the East Side Division, which would provide 1,500,000 acre-feet of service to that area with its resulting multiple-purpose benefits. The estimated capital cost of the proposed facilites, exclusive of distribution

Lands acquired by the States upon adminssion to the Union were generally leased to stockmen. The enactmence of the Taylor Grazing Act in 1934 finally provided the means to establish control over the public domain lands. It authorized the regulation of use and the initiation of rehabilitation measures. This latter was necessary as most of the lands had badly deteriorated from many years of misuse. Excessive stocking of the range had resulted in the diminution of the better forage plants and permitted the establishment, or spread, of less desirable plant species.
G. Present economic development
The economic growth rate of the report area is one of the highest in the country. The growth is accompanied by an increasing diversification of the economy. The principal sources of income for the area are currently derived from manufacturing, mining, tourism, crops, and livestock in that order.
Manufacturing is the economic activity which has achieved the greatest gains in recent years. The manufacturing activities include electronics, aerospace industries, clothing, chemicals, metal processing, food processin printing and publishing, machinery, lumber, and a host of other light manufacturing enterprises.
The mining activity is based upon a wide variety of minerals, most important of which is copper. Asbestos, molybdenum, manganese, barite, lims gypsum, and perlite are among the long list of minerals which have become substantial factors in the economy.

Roughly 300 million board feet of lumber are harvested annually. The chief sawmill operations are located in Flagstaff, Williams, Winslow, Fredonia, Springerville, Heber, and McNary.
Although less than 2 percent of the basin is under cultivation, the production of crops, virtually all by irrigation, is a vital segment of the region's economy. Yields per acre are among the highest in the Nation in both quantity and value. Crops produced include cotton, lettuce and other vegetable crops, melons, commercial hay and seed, dairy products, poultry, citrus fruits, and many others. Major dams, such as Roosevelt, Horse Mesa, Mormon Flat, Stewart Mountain, and Granite Reef on the Salt River, Horseshoe and Bartlett on the Verde, Coolidge on the Gila, Lyman on the Little Colorado, and Hoover, Davis, Parker, Laguna, and Imperial on the main stream of the Colorado River provided the means for the development in the last 50 years of an intensive and greatly expanded irrigation agriculture. Development of the groundwater supply has occurred throughout the basin, but the developments in the Safford Valley and in Pinal County on the Gila River are particularly dependent on pumped water. This agricultural use, coupled with increasing demands on groundwater for industrial, commercial, and urban residential uses, has resulted in a general lowering of groundwater tables. The situation is critical in many areas. The means to acquire additional water must be identified, as well as techniques to make optimum use of existing supplies if present requirements are to be met and further economic growth is to be achieved.

These aspects of the project reservoirs, and the relationship between Federal and other responsibilities for paying the costs of recreation, require thorough review in the light of Senate Document 97 of the 87th Congress and the inter-Departmental policies being developed to implement that document.
3. The Secretary of the Interior should be authorized to take all appropriate steps to minimize damage to scenic qualities of reservoir areas.
4. An analysis is needed of the recreation potentials of the Bridge Canyon and Marble Canyon projects to determine whether they are of national or less than national significance, so that responsibility for the administration of the recreation features can be assumed at the appropriate level of government. At the other reservoirs, the recreation use is expected to consist primarily of day use and other short-term visits from the near-by vicinity. Administration of the recreation aspects of these reservoirs should be the responsibility of suitable State or local agencies.
