This report presents the results of definite plan studies of the Southern Nevada Water Project in Clark County, southeastern Nevada. Construction of this project was authorized under Public Law 89-292 dated October 22, 1965. Authorization of the Southern Nevada Water Project was based on a project plan outlined in the feasibility report of August 1963 as supplemented in April 1965. The definite plan studies have confirmed the general project plan of the 1963 report as supplemented but some important modifications are now contemplated as explained in Part IV.

The project will be constructed in three stages. Stage development is desirable to provide flexibility in the timing of future installations, and to allow for deviations from the projected future growth rates of population and industry. Presently contemplated future stages can be altered or eliminated and new features incorporated as may be needed to meet changes in trends of growth or shift in area of use. This report is limited to the first stage of construction. Authority to make this report is provided by the Federal Reclamation Laws (Act of June 17, 1902, 32 Stat. 388 and Acts amendatory thereof or supplementary thereto).

The State of Nevada has designated the Colorado River Commission of Nevada as the state agency to contract with the Secretary of the Interior of the United States for repayment of project costs, and to accept transfer of the care, operation and maintenance of such water service facilities.
