Summary

To control floods, help river navigation, store and deliver water inside the United States, reclaim public lands, and make the project pay for itself by producing electricity, the Secretary of the Interior may build, run, and maintain a dam and other works on the main Colorado River at either Black Canyon or Boulder Canyon. The reservoir must hold at least 20,000,000 acre-feet. The Secretary may also build a main canal and related structures inside the U.S. to link Laguna Dam (or another diversion dam he finds necessary) with the Imperial and Coachella Valleys in California. The cost of the main canal can be repaid under the reclamation law, but those repayments cannot come from electricity sales at the dam or from charges for drinking water used outside the Imperial and Coachella Valleys. No fee may be charged for irrigation or drinking water in the Imperial or Coachella Valleys. The Secretary may build and run a power plant at or near the dam and may acquire land, rights-of-way, or other property needed, including by eminent domain. The work must follow the Colorado River Compact.
