Title 43 › Chapter CHAPTER 32— - COLORADO RIVER BASIN PROJECT › Subchapter SUBCHAPTER V— - GENERAL PROVISIONS › § 1551
Protects existing Colorado River agreements and the court order from being changed. That includes the Colorado River Compact, the Upper Colorado River Basin Compact, the 1944 Water Treaty with Mexico, the Supreme Court decree in Arizona v. California, and, unless this law says otherwise, the Boulder Canyon Project Acts and the Colorado River Storage Project Act. The Secretary must do two things: every five years starting October 1, 1970, make reports on annual water use and losses with a state-by-state and major-tributary breakdown, done with the lower basin states and the Upper Colorado River Commission and sent to the President, Congress, and the Governors who signed the Compact; and make all Colorado River water delivery contracts depend on water actually being available under the Compact. All federal officers and agencies must follow these laws when storing, releasing, operating, or maintaining Colorado River reservoirs and related works. If a federal officer or agency fails to comply, any affected State may sue in the U.S. Supreme Court, and the United States agrees to be joined as a party in that suit.
