conditions. It differs from the January 1962 appraisal report which

.:

was financed entirely by the States, principally in that it includes

c.

further refinements of the data previously mentioned, as well as ~

recolJlJJlendations in the light of the June 3, 1963, decision of the

Supreme Court. It provides data on present water usage and problems

in the area within the framework of the national policy for the use

and developnent of water and related land resources which have been

adopted since the 1947 report was issued. The water supply available

to the area from local surface and underground sources has been

reexamined and reanalyzed on the basis of present conditions.

This report presents essentially the same plan as in the 1947 report.

Most project works have been redesigned in accordance with recent

engineering advancements, and all project costs have been reestimated

at July 1961 price levels. All project features have been actually

located in the field or designed on the basis of field data. Estimated

costs presented in this supplement are suitable for the purpose of

evaluating feasibility of the project under present conditions.

Plan of Development
The plan of development, as originally set forth in the 1947 report,

provides for the conveyance and delivery of Colorado River water

through the main project aqueduct system, extending from Lake Havasu

to the Central Arizona Project service area. In accordance with the

concepts outlined in the 1947 report, direct deliveries of Colorado

River water in central Arizona would, through water exchanges, also

permit additional water uses to be made in other areas.
