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

Last updated Aug 21, 2026|Official source

Summary

Keeps existing Colorado River and related federal agreements and laws in place and unchanged. That includes 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 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). Also says this chapter does not change how federal law works with state, tribal, or local law, and it does not free anyone from duties under state, tribal, or local law. State, tribal, or local rules stay valid unless they directly conflict so they cannot both work. The task force will review such conflicts and make recommendations. The chapter does not stop a State or tribe from protecting or restoring lands inside its borders.

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.
