At Hoover Dam on May 20, the U.S. Bureau of Reclamation hosted the seven Colorado River Basin states at a ceremony to celebrate the signing of the Colorado River Drought Contingency Plans. The jubilant mood of the dignitaries masked a grim reality facing the Basin states: legal rights to Colorado River water exceed the amount of water in the river, which supplies water to 40 million people and irrigates 5.5 million acres of farmland. The act authorizing the plans, which Congress enacted in a rare display of bipartisanship, is only a few paragraphs long. It simply instructs the secretary of the interior to carry out the provisions of various state drought plans.
