Summary

The Secretary may build, run, and keep up well fields that can supply approximately 160,000 acre-feet of water each year for use in the United States and to deliver water to Mexico to meet the 1944 Mexican Water Treaty under Minute No. 242. The Secretary may acquire, by buying, using eminent domain, or trading, approximately 23,500 acres of land near the Mexican border on the Yuma Mesa (about five miles of border). Land now owned by the State of Arizona may be bought or swapped for federal land. Any lands taken out of the Yuma Mesa Irrigation and Drainage District that had been available under the Gila Reauthorization Act must be replaced with similar lands inside or next to the Yuma Mesa division. When developing those replacement lands or other Gila project lands, the Secretary may allow full use of the Gila Gravity Main Canal. Effective October 1, 1979, and only to the extent and in the amounts provided in advance in appropriation Acts, the Secretary may enter into contracts under the Reclamation Act to deliver well-field water to U.S. cities, industries, or farms. Municipal and industrial contracts must include terms like those in section 485h(c)(1). Contracts that replace irrigation water for privately developed lands must charge no more than if those users had kept pumping their own wells, and the usual Reclamation Law acreage limits will not apply to those private lands. No contract may reduce the United States’ ability to continue delivering approximately 140,000 acre-feet per year to Mexico at San Luis and the Limitrophe Section, as required by Minute No. 242. The cost of the work, including water sent to Mexico, is nonreimbursable except for the portion of the water that is used in the United States.

(2)Acquire by purchase, eminent domain, or exchange, to the extent determined by him to be appropriate, approximately twenty-three thousand five hundred acres of lands or interests therein with approximately five miles of the Mexican border on the Yuma Mesa: Provided, however, That any such lands which are presently owned by the State of Arizona may be acquired or exchanged for Federal lands.
(3)Any lands removed from the jurisdiction of the Yuma Mesa Irrigation and Drainage District pursuant to clause (2) of this subsection which were available for use under the Gila Reauthorization Act (61 Stat. 628) [43 U.S.C. 613 et. seq.], shall be replaced with like lands within or adjacent to the Yuma Mesa division of the project. In the development of these substituted lands or any other lands within the Gila project, the Secretary may provide for full utilization of the Gila Gravity Main Canal in addition to contracted capacities.
(4)Effective October 1, 1979, and to such extent and in such amounts as are provided in advance in appropriation Acts, enter into contracts under the terms and conditions of the Act of June 17, 1902 (43 U.S.C. 371 et seq.) as amended and supplemented for the delivery of water from said well field to entities within the United States for municipal and industrial or irrigation purposes: Provided, That such contracts for municipal and industrial purposes shall contain terms and conditions as substantially provided in section 485h(c)(1) of this title, and that contracts for replacement irrigation water supplies to prevent damage to existing water users on privately developed lands include water charges no greater than if such water users had continued to pump their own wells without the United States lowering the water table and that the acreage limitation and related provisions of the Reclamation Law will not be applicable to such privately developed lands: Provided further, That no contract shall be entered which will impair the ability of the United States to continue to deliver to Mexico on the land boundary at San Luis and in the Limitrophe Section of the Colorado River downstream from Morelos Dam approximately one hundred and forty thousand acre-feet annually, consistent with the terms contained in Minute No. 242 of the IBWC.
(b)The cost of work provided for in this section, including delivery of water to Mexico, shall be nonreimbursable; except to the extent that the waters furnished are used in the United States.
