Significant declines in Colorado River flows likely to continue as temperatures rise

• Colorado River flows were, on average, nearly 20 percent below the 1906-1999 average between 2000 and 2014, according to the study, published in the journal Water Resources Research earlier this month.
• That’s a reduction of about 2.9 million acre-feet of water per year. To put that in context: It’s been estimated that one acre-foot of water is the amount used by a family of four in one year.
• The multi-year drought in California receives far more press, but the Colorado River drought is just as severe and will also have far-reaching impacts, note the researchers with the University of Arizona (UA) and Colorado State University (CSU) who authored the study.
