Title 43 › CHAPTER 12A — BOULDER CANYON PROJECT › SUBCHAPTER I — BOULDER CANYON PROJECT ACT › § 617c
No work can start, no money can be spent, and no water rights can be claimed under this subchapter until the Colorado River compact is approved by the states named (Arizona, California, Colorado, Nevada, New Mexico, Utah, and Wyoming) and the President declares it so. If those states do not all ratify the compact within six months from December 21, 1928, then the rules don't take effect until six of those states, including California, approve the compact without conditions and the President declares that, and until California’s legislature agrees forever that its annual use of Colorado River water will not exceed 4,400,000 acre-feet plus at most one-half of any surplus water not apportioned by the compact. Arizona, California, and Nevada may make a three-state agreement that divides the lower basin’s 7,500,000 acre-feet so Nevada gets 300,000 acre-feet and Arizona gets 2,800,000 acre-feet forever; lets Arizona use one-half of surplus unallocated water each year; gives Arizona exclusive use of the Gila River in Arizona; protects Gila water from being reduced for Mexico except as the compact requires; says California and Arizona will split any extra water needed for Mexico beyond surplus amounts; and says the three states will not withhold or force delivery of water that cannot reasonably be used. That tri-state deal must follow the compact and starts when Arizona, California, and Nevada ratify the compact. Before money is appropriated for the dam, power plant, or the main canal linking Laguna Dam to the Imperial and Coachella Valleys, the Secretary of the Interior must arrange contracts or other revenue that the Secretary thinks are enough to pay operation and maintenance costs and to repay amounts advanced for construction within fifty years after the works are finished, with interest. If, while loans are being paid off, the Secretary gets more revenue than needed for the scheduled payments, then after making those payments he must pay Arizona 18¾ percent and Nevada 18¾ percent of the excess.
