Title 43 › Chapter CHAPTER 32B— - COLORADO RIVER FLOODWAY › § 1600g

Last updated Apr 6, 2026|Official source

Summary

Nothing here changes or conflicts with the listed river and water laws, treaties, and court decisions. That includes the Colorado River Compact (45 Stat. 1057), the Upper Colorado River Basin Compact (63 Stat. 31), the Water Treaty of 1944 with Mexico (Treaty Series 944, 59 Stat. 1219), the Flood Control Act of 1944 (58 Stat. 887), the Supreme Court decree in Arizona v. California (376 U.S. 340), the Boulder Canyon Project Act (45 Stat. 1057), the Boulder Canyon Project Adjustment Act (54 Stat. 774), the Colorado River Storage Project Act (70 Stat. 105), and the Colorado River Basin Project Act (82 Stat. 885). Federal law here does not change how other federal laws relate to state, tribal, or local law. It does not free anyone from duties under state, tribal, or local law. A state, tribe, or local rule is only invalid if it directly conflicts and cannot stand with federal law. Any mismatches will be reviewed by the task force, which will make recommendations. These rules do not stop a State or tribe from protecting or restoring lands inside their borders.

Nothing contained in this chapter shall be construed to alter, amend, repeal, modify, interpret, or be in conflict with the provisions of the Colorado River Compact (45 Stat. 1057), the Upper Colorado River Basin Compact (63 Stat. 31), the Water Treaty of 1944 with the United Mexican States (Treaty Series 944, 59 Stat. 1219), the Flood Control Act of 1944 (58 Stat. 887), the decree entered by the Supreme Court of the United States in Arizona v. California, and others (376 U.S. 340), the Boulder Canyon Project Act (45 Stat. 1057) [43 U.S.C. 617 et seq.], the Boulder Canyon Project Adjustment Act (54 Stat. 774; 43 U.S.C. 618a) [43 U.S.C. 618 et seq.], the Colorado River Storage Project Act (70 Stat. 105; 43 U.S.C. 620) [43 U.S.C. 620 et seq.], the Colorado River Basin Project Act (82 Stat. 885; 43 U.S.C. 1501) [43 U.S.C. 1501 et seq.]. Furthermore, nothing contained in this chapter shall be construed as indicating an intent on the part of the Congress to change the existing relationship of other Federal laws to the law of a State, or a political subdivision of a State, or to relieve any person of any obligation imposed by any law of any State, tribe, or political subdivision of a State. No provision of this chapter shall be construed to invalidate any provision of State, tribal, or local law unless there is a direct conflict between such provision and the law of the State, or political subdivision of the State or tribe, so that the two cannot be reconciled or consistently stand together. Inconsistencies shall be reviewed by the task force, and the task force shall make recommendations concerning such local laws. This chapter shall in no way be interpreted to interfere with a State’s or tribe’s right to protect, rehabilitate, preserve, and restore lands within its established boundary.
