No full textDocument: Pacific Southwest Water Plan "Printed Copy" Chapter VIII, August 26 ,1963 page 6f. Dixie Project, the principal works of which will consist of the Virgin City Dam, reservoir, powerplant, transmission, and appurtenant facilities; Santa Clara Dam and reservoir; canals, pumping plant, transmission, and related facilities.
g. Desalting plant of a 50-million-gallon-per-day capacity, the principal works of which will consist of a distillation plant and conveyance facilities to tie to municipal water systems. It is proposed that the powerplant needed in conjunction with the desalting plant will be constructed by local interests.
h. Indian Irrigation Projects in Arizona, California, and Nevada. It is intended that Indian reservations, whose water rights were confirmed in the recent opinion in Arizona v. California, et al., will have construction initiated and existing project completed to utilize their rights. It is proposed that construction costs within the ability of the lands to repay be subject to the Act of July 1, 1932 (47 Stat. 564) and, in recognition of the fact that assistance to Indians is a matter of national concern, that any costs in excess of the capability of such lands to repay shall be nonreimbursable.
i. Fish and Wildlife and Recreational facilities are also planned for immediate construction in connection with all works being undertaken as part of the Pacific Southwest Water Plan. Such plans include facilities for the propagation of fish and wildlife, the creation and development of wildlife refuges to mitigate losses of present wildlife habitats and facilities necessary to provide public recreational activities, to conserve the scenery, natural, historic, and archeologic objects within the areas utilized by the works authorized under the Pacific Southwest Water Plan. Costs incurred in connection with such facilities should be nonreimbursable.
j. Water Salvage programs to eradicate and control phreatophytes presently consuming Colorado River waters.
k. Ground-Water Recovery programs in Arizona and California to conserve existing supplies of water now lost through percolation out of areas of use. The principal works will include wells, pumps, transmission facilities, and conveyance channels.
Continuing Project Development Program
It is contemplated that large-scale projects be constructed to provide supplemental water supplies to meet future needs of the Pacific Southwest. These projects, however, can be authorized and staged in phases as the water needs of the areas expand.

Pacific Southwest Water Plan - Report August 1963
No full textDocument: Pacific Southwest Water Plan "Printed Copy" Chapter IX, August 26 ,1963 page 9Topographic Mapping Requirements--The following proposal for topographic mapping in the Pacific Southwest would accelerate, moderately, earlier tentative schedules of the Geological Survey. It is so paced to facilitate general studies involved in the Pacific Southwest Water Plan. It would supply Federal agencies and the general public with advance map materials, including aerial photography and geodetic-control lists, as well as with published maps.
Of the 180,000 square miles in the Pacific Southwest, as here defined, about 113,500 square miles, or 63 percent, are covered by topographic maps of standard accuracy. Most of these maps are published, but a few are in advance copy. In addition, mapping is in early stages over about 7 percent of the area.
There is proposed a short-range, or 6-year, schedule of topographic mapping that would complete work not in progress and would make new starts in 1965-1967. Latest of the new startes should produce advance copy by 1969 and published maps by 1970. The proposed schedule is based on the construction priorities understood to have been set by the Bureau of Reclamation.
In total, the short-range mapping schedule would cover about 14,500 square miles in six project areas.
This long-range schedule for the Pacific Southwest calls for complete topographic coverage by 1976.
Geologic and Mineral-Resource Investigations--Two programs of geologic and mineral-resource investigations in the Pacific Southwest are: a short-range program that is related immediately to development and management of the water resource and that can be accomplished within 5 years, and a long-range program that would cover all the region comprehensively within a 35-year period.
Classification of Federal Mineral Lands--In Arizona, the Geological Survey proposes to accelerate its classification of Federal mineral lands. Classification would conserve useful mineral deposits under confirmed withdrawals and would release barren lands. Thus, areas of possible conflict between management programs for water and for minerals would be minimized.
Involved in Arizona are about 3,400,000 acres prospectively valuable for sodium and 140,000 acres for coal. These lands should be mapped and classified as to their mineral potential to provide needed information to permit orderly development of any mineral, mineral-fuel, and mineral-fertilizer resources.

To attempt to document in this section the wealth of information, plans, and alternative plans that have been considered to accomplish various purposes would be beyond the physical limits of this appendix. For this purpose a list of completed, or soon to be completed, project reports is given, and a section of alternative plans for the California supplemental diversions is included.

EAST SIDE ROUTE
This plan will conserve and convey an additional water supply of 1,200,000 acre-feet per year by storage on Trinity River and conveyance through East Side Division facilities, and thence through the California Aqueduct to southern California.
To obtain the additional yield of water, two storage reservoirs are proposed on the Trinity River. Helena Reservoir, with a gross storage capacity of 2,800,000 acre-feet, would be built on the main Trinity River downstream from Lewiston Dam. This reservoir would develop an annual new water yield of 600,000 acre-feet which would be diverted to the Sacramento River. 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 facilities are 540,000,000. Annual OM&R costs would be offset by power revenues, with a net annual amount remaining of about 9,000,000.
This plan proposes to add a 2,000 c.f.s. increment to the proposed East Side Division conveyance facilities from the Sacramento RiverEpson Perfection 4870 Photo, 400 dpi, 8 bit, 2,603,086 byte

In addition, the channel will provide maximum protection to the large resident and anadromous fisheries that use the present Delta channels.
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 the 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 now is being served in part by the Central Valley Project. This proposed unit also would provide operational flexibility for the Central Valley Project through integration with operations of Tracy Pumping Plant and the proposed 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.

The capital cost of these tunnel diversions, including facilities to convey the water to Colorado River (exclusive of exchange and storage facilities), is estimated to be 950,000,000, on a reconnaissance basis, and the annual OM&R 2,300,000, not including cost of pumping energy. The cost of pumping will be offset by power generated. The net power generated is estimated to return an annual revenue of 200,000,000, including the estimated amount required to offset the adverse effect on existing powerplants below the tunnel diversions. The annual OM&R and pumping costs are estimated to approximate $5,600,000 annually.
The additional water, 1,200,000 acre-feet, required for exchange purposes would be conserved in two storage reservoirs proposed on Trinity River. Helena Reservoir, with a gross storage capacity of 2,800,000 acre-feet, would be built on the main Trinity River downstream from Lewiston Dam. This reservoir would develop an annual new water yield of 600,000 acre-feet which would be diverted to the Sacramento River. Subsequently, Eltapom Reservoir, with a gross storage capacity of 3,100,000 acre-feet, would be constructed on the South

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 facilities, 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 9,000,000.
The estimated total capital cost (reconnaissance) for this prospective plan, including tunnel conveyance to Lake Havasu on Colorado River, exchange conveyance facilities, and storage reservoir systems is 1,690,000,000. The annual OM&R and pumping costs are offset by power generated, with an estimated annual revenue remaining of 7,700,000.
Under this proposal, therefore, the additional 1,200,000 acre-feet of water would be stored and conveyed to southern California at an estimated annual equivalent cost of $57.35 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.

Of the 180,000 square miles in the Pacific Southwest as here defined, about 113,500 square miles or 63 percent is covered by topographic maps of standard accuracy. (See fig. 3). Most of these maps are published, but a few are available in advance copy only. In addition, mapping is in early stages over about 7 percent of the area.
This completed mapping covers most of the areas of the Central Arizona Aqueduct, Charleston Dam and Reservoir, and Marble Canyon Dam and Reservoir units understood to be proposed by the Bureau of Reclamation. With work in progress, it also covers parts of the Granite Reef Aqueduct, Maxwell Dam and Reservoir, and Buttes Dam and Reservoir units.
Short-range Schedule
There is proposed a short-range or six-year schedule of topographic mapping to complete work now in progress and to make certain new starts in 1965-1967. Latest of the new starts would produce advance copy by 1969 and published maps by 1970. The proposed schedule is based on the construction priorities understood to have been set by the Bureau of Reclamation, also on Survey proposals for hydrologic and geologic investigations. In total, the six-year mapping schedule would cover about 14,500 square miles in six project areas, as follows:
Project Square Miles Year to Start
Reserve north 740 1965
Granite Reef Aqueduct and other Central Arizona Project work 2,400 1965
Hooker Dam and Reservoir unit 1,450 1965
Bridge Canyon 1,950 1966-1967
Kaiparowits Plateau and Kanab Coal field 950 1966-1967
Other mapping 7,000 1966-1967
Completion of the Bridge Canyon project under this schedule will provide topographic coverage, in either the 71/2- or the 15-minute series, of all the reach of the Colorado River from the Utah-Colorado boundary to the United States-Mexico boundary. (See fig. 3).
