Title 43 › CHAPTER 32 — COLORADO RIVER BASIN PROJECT › SUBCHAPTER V — GENERAL PROVISIONS › § 1552
The Secretary of the Interior must make rules for running the Colorado River reservoirs over the long term so the United States can meet the Colorado River Compact, the Upper Colorado River Basin Compact, and the U.S.-Mexico water treaty. The rules must say how water is stored and released from Lake Powell in this order: first, release water to cover one-half of any shortfall under article III(c) that the Upper Division states are responsible for, except in years when the Secretary issues the special proclamation under section 1512; second, release water needed to meet article III(d), after crediting water delivered from other sources; third, store water not needed for the first two priorities when the Secretary—after consulting the Upper Colorado River Commission and the Lower Division states and looking at historic flows and supply chances—finds storage is needed to protect those deliveries without harming Upper Basin uses. Water not required to be stored must be released from Lake Powell to help Lower Division uses when practical, to keep Lake Mead’s active storage roughly equal to Lake Powell’s, and to avoid spills. By January 1, 1970, the Secretary must send the proposed rules to the seven basin Governors and others for comment, adopt and publish final rules by July 1, 1970, and then send yearly reports to Congress and the Governors starting January 1, 1972. Section 7 of the Colorado River Storage Project Act must be run under these rules.
