Supporting Material The above presentation outlines the plan set forth in the Task Force report of August 1963, reviews the comments received from the States and Federal agencies, presents a modified or Initial Plan for your approval, and indicates major steps proposed for implementing the plan. To more fully present the Pacific Southwest Water Plan, the Task Force report has been revised in its entirety, but along the lines of its original format, to reflect the modifications adopted as a result of State and Federal agency review. The modified report is attached. In the modified report the following chapters remain essentially unchanged: Chapter I - The Pacific Southwest; Chapter II - The Water Problem; Chapter III - Present Water Supplies and Uses; Chapter V - Power Requirements, Sources, and Markets; and Chapter IX - Study and Research. The remaining chapters have been revised substantially. Revisions to the Appendix material are inserted where appropriate in front of the individual appendices of the Task Force report. Revisions have been made only in the appendices of the Bureau of Reclamation, Bureau of Outdoor Recreation, Bureau of Sport Fisheries and Wildlife, and the Bureau of Indian Affairs. Attached also are reports containing supplemental information on the Bridge Canyon Project, the Marble Canyon Project, the proposed water salvage programs, the Central Arizona Project (including as an annex the report of June 1963), the Southern Nevada Water Supply Project, and the Moapa Valley Pumping Project. The report of the Secretary of the Interior on the Dixie Project published as House Document No. 86, 88th Congress, contains full supporting information on that project. Recommendations It is recommended that the Congress of the United States be asked to approve the Initial Plan and to implement it by the following: (1) Guarantee, as a matter of Federal policy through the construction of necessary works, the equivalent of 7.5 million acre-feet of water per year in the Colorado River, either directly or through exchange, to satisfy the consumptive use of: 2.8 million acre-feet per annum in Arizona; 4.4 million acre-feet per annum in California; 0.3 million acre-feet per annum in Nevada; at cost to users no greater than would otherwise have been incurred had there been sufficient water in the river to satisfy the aforesaid amounts. 35Epson Perfection 4870 Photo, 400 dpi, 8 bit, 13,666,304 byte
