No full textDocument: "Appraisal Report Central Arizona Project-Chapter I", January 1962, page 2Recently, recreation center activities have accelerated the growth. The prior appropriation of surface water for the lower agricultrural valleys now limits the growth possibilities of these upper river areas.
Settlement
Since obtaining territorial status in 1863, Arizona has experienced a continuing growth pattern accelerated at times by mining activity, but provided a steady base by development of livestock and agricultural operations Early agricultural development, which supplied local military and mining community needs, continued to grow after railroad transportation became generally available by 1887. Growth has always been related to water supply and control and has been continuous since agriculture was placed on a firm productive basis by establishment of the Salt River and other irrigation projects. Eighty-five percent of Arizona's population lives within the Gila River basin. The rapid population increase since the 1947 report has been accompanied by an influx of light manufacturing industries, with an attendant growth of service industries. Influencing this population explosion have been the technological advances made in air transportation, climate modifying ariconditioning equipment, and the general economic well-being of the states and the Nation.
Project Area
In appraising the Central Arizona Project, it is necessary to examine the water demands and resources within the hydrologic entity where they occur. For this reason the Central Arizona Project area has been divided into two separable zones designated in this report as the Central Service Zone and the Upper Tributaries Zone. The Central Service Zone contains those lands primarily in Maricopa, Pinal, and Pima counties of Arizona to which

Income from mining activities in Arizona totaled over $400,000,000 in 1960. New Mexico ranks fifth nationally in nonferrous mineral production. Continuing exploration and technological advances are proving extensive mineral deposits, unknown or undeveloped in the past, which will continue to play a major role in the economy of the area. Water availability is a prime requirement for developing and processing mineral deposits which will continue to influence mining activity and, in turn, influence other requirements for water.
Economy of the Area
The Gila River Basin, in general, is a dynamic sector of the Nation's economy. For the period 1946-1960, Arizona ranks as the Nation's leader in such rate of growth indices as population, income, nonagricultural employment, agricultural income, manufacturing employment, and nonferrous mineral production. New Mexico ranks from second to no lower than eighth in the same statistics.
At the present time, the Central Service Zone is a modern, progressive area with highly developed community centers affording its residents a standard of living higher than the national average. The 1960 census enumerated a population of about 1,000,000 people for the area, an increase of almost 100 percent since 1950.
The Upper Tributaries Zone and adjoining areas are also being subjected to the pressures of expanding population and economic growth. New roads are decreasing the distance and time between the population centers in Arizona and New Mexico. Additional development of natural resources is providing a larger industrial base. The increasing development of the mountain and plateau areas is a result of the general western population and economic growth,

Table 7 also shows the estimated construction periods for the various features, together with the estimated overall sequence of construction for the entire project.
Operation, maintenance and replacement cost estimates--Estimated annual operation, maintenance, and replacement costs under full operating conditions are shown on table 8. These costs include allowances for the wages of operators, ditchriders, maintenance labor, and administrative personnel, together with the cost of maintenance and transportation equipment, office, warehouse and special facilities, and materials and supplies. They also include the cost of replacing project facilities at the end of their useful lives, the cost of furnishing project-use energy from Bridge Canyon Powerplant, and the storage-delivery charge from the Boulder Canyon Project.
Subsidiary Facilities
The construction of certain Central Arizona Project features would materially aid in the development of important and nationally beneficial subsidiary facilities. For example, the construction of Bridge Canyon Dam, with an access road from U.S. Highway 66 on the south, would provide opportunity for opening up one of the most scenic and inaccessible regions of the United States through an extension of the road from the dam, northerly to U.S. Highway 91. Such a road would not only provide unmeasured recreational benefits through access to the spectacular Lake Mead National Recreation. Area and the Grand Canyon National Monument, but would also benefit the isolated northern Arizona strip country which presently is accessible to its own county seat and the balance of Arizona only by traveling through the States of Nevada or Utah. It is estimated that as much as $30,000,000 might be required to bridge the Colorado River at the

If it should be determined that such a bridge and highway are to be included in the project plan, it is assumed that the cost would be assignable to recreation on a nonreimbursable basis and thus would not affect the payout analysis included in this report. It is pointed out, however, that if these facilities are included on a reimbursable basis there are insufficient surplus power revenues in the payout analysis for this purpose. Extensions of the road from the National Recreation Area boundary to existing highways could properly be left to cooperative efforts of the States of Arizona, Nevada, and Utah. Opportunities for similar subsidiary benefits are present on a smaller scale at nearly all project dams and reservoirs. The limited scope of present studies did not permit consultations with the National Park Service and the several affected states regarding their interest in these facilities.

9. CREATION OF INTERIOR-CHAIRED PLANNING COMMISSION
Budget would modify "discretion of President"
Interior position - Supreme Court decree and existing legislation confer major and unique responsibilities for Colorado River development and regulation in Secretary of Interior. This dictates departure from S. llll (Administration Planning Bill).
Agency comments - Army and Agriculture opposed to departure from S. llll. Army also considers this would give Interior undue control over Army programs in California and wants "savings clause" for its program authorities.
Comments - Interior's dominant role in the Colorado is recognized, but the concern of agencies on possible threat to S. llll as precedent for further departures, is legitimate. Army's concerns on Interior oversight of its programs are understandable. Under these circumstances, the language of S. llll (providing for a commission with an independent chairman) should be inserted as a separate title in the draft bill in place of Interior's language, thus assuring consistency with the Administration's planning bill in every appropriate aspect.
10. STATE ACTION TO CONTROL GROUND WATER OVERDRAFT AS CONDITION OF FEDERAL APPROPRIATIONS
Interior position - The Department says that not only would it be impossible to achieve a balance between ground water pumping and supply in Arizona, but the State would never agree to adopting controls which might seriously interfere with the operations of individual irrigators and which might result in wholesale disruption of the economy. Future planning to import further supplies into Central Arizona is the answer. This would be done later by the proposed regional water commission.
Comments - The State should be required to exercise some initiative to control the deteriorating ground water overdraft problem. Otherwise the Central Arizona project will create a false sense of security, and thus merely postpone a day of reckoning.
11. DEFER AUTHORIZATION PENDING FORMULATION OF COMPREHENSIVE AND COORDINATED PLAN
This suggestion was made by Agriculture, Army, HEW and OST. In formulating the Plan to head off a conflict between Arizona and California over authorization of the Central Arizona project (S. 1658), the Secretary has not had time to afford the concerned agencies an adequate opportunity to participate in time to have any significant impact on the Plan. Agriculture, Army, HEW, and OST are unanimous in pointing out that the Plan is neither comprehensive nor coordinated. As expressed by Army: "Major contributions from the several Federal departments and agencies with large programs within the region are conspicuously absent." Agency participation, in short, has been largely limited to commenting on a finished product.Epson Perfection 4870 Photo, 400 dpi, 8 bit, 2,226,150 byte
