Colorado River Basin Water Security and Infrastructure Act

(a) In general. The Secretary shall use the authorities provided under this Act and section 202 of the Colorado River Basin Project Act (43 U.S.C. 1512) to maximize the extent to which augmentation of the Colorado River system reduces the quantity of Colorado River water required from the States of the Upper Division and States of the Lower Division to satisfy the requirements of the Mexican Water Treaty.

(b) Mexican compliance. Before crediting any water produced through a project authorized under this title toward satisfaction, reduction, replacement, or offset of any obligation of the United States under the Mexican Water Treaty, the Secretary, in consultation with the Secretary of State, shall determine that Mexico is in compliance with its applicable obligations under the Mexican Water Treaty, including any obligation to deliver or return water to the United States under the Mexican Water Treaty.

(c) Noncompliance. If the Secretary determines that Mexico is not in compliance with an applicable obligation under the Mexican Water Treaty, the Secretary shall—

(1) notify the Secretary of State and the appropriate committees of Congress of the noncompliance; and

(2) suspend any additional Federal benefit under this title that is contingent upon Mexican compliance until the Secretary determines that the noncompliance has been remedied or otherwise resolved pursuant to the Mexican Water Treaty.

(d) Proclamation. Upon determining that means are available and in operation that augment the water supply of the Colorado River system in a quantity sufficient to satisfy the requirements of the Mexican Water Treaty and associated losses, and that Mexico is in compliance with its applicable obligations under the Mexican Water Treaty, the Secretary shall make the determination and proclamation required under section 202 of the Colorado River Basin Project Act (43 U.S.C. 1512).

(e) No reduction of Mexican delivery. Nothing in this title shall be construed to reduce any obligation of the United States to Mexico under the Mexican Water Treaty.

(f) No waiver of Mexican obligations. Nothing in this title shall be construed to waive, reduce, modify, or otherwise impair any obligation of Mexico under the Mexican Water Treaty.
