"Five years of record-breaking drought in the Colorado River basin have drained Lake Powell of more than 60% of its water. Flows on the Colorado are among the lowest in 500 years... 'They've never had to face a shortage of this consequence,' said Pat Mulroy, head of the Southern Nevada Water Authority that supplies Las Vegas, one of the most river-dependent cities in the Colorado basin... If the law of the river was strictly followed, cuts would be made according to a hierarchy of water rights, with Arizona, Nevada and the upper basin states of Colorado, Wyoming and Utah taking the first hits. California, which gets about 14% of its statewide water supply from the river, has some of the most senior rights on the Colorado and is in a comparatively good position."
