the Pacific Southwest Water Plan must not be deferred pending completion of these studies since such studies will be carried out on a continuing basis for the foreseeable future. Water Quality Management The maintenance of water of acceptable quality in the Colorado River, the delta of the Sacramento-San Joaquin Rivers, and other areas of the region is of extreme importance. Cooperative Federal-State studies should be continued and expedited with the objective of assuring sound water quality management practices throughout the region. Study and Research The facilities recommended for authorization as a part of the Pacific Southwest Water Plan cannot meet the long-term needs of the region. Much research and planning must be done before the additional projects which will be needed can be properly identified and evaluated as to economic justification, feasibility, and phasing. Accordingly, it is contemplated that the implementing legislation would authorize the Secretary of the Interior to carry out accelerated general investigation and research programs associated with ways of meeting these future needs within the Pacific Southwest including, but not limited to, potential sources of additional import supply, the fields of saline water conversion, canal sealants, evaporation reduction, weather modification, waste-water renovation, general hydrology, water quality and waster management, water salvage, and fish and wildlife conservation. The accelerated general investigations and research program should proceed concurrently with construction of those elements included under the immediate authorization program. Construction of those urgently needed projects should in no event be delayed because of this study and research must continue indefinitely. Pending Legislation Authorization is currently being sought in the Congress by the States of Arizona, Nevada, and Utah for three of the projects included in the Initial Plan, namely: the Central Arizona Project (S. 1658), the Southern Nevada Water Supply Project (S. 2388), and the Dixie Project (S. 26), all with accompanying identical bills in the House of Representatives. Bureau of Reclamation reports demonstrating economic and engineering feasibility of each of these projects are attached as supplemental information supporting this report. These three projects are included without change in the principal physical works involved for immediate authorization as integral parts of the Initial Pacific Southwest Water Plan which provides at the same time for the establishment of the Pacific Southwest Development Fund and for incorporation of these projects in the Plan.
