Following one of the hottest and driest years on record, the Colorado River and its tributaries throughout the western U.S. are likely headed for another year of low water. That’s according to a new analysis by the Western Water Assessment at the University of Colorado Boulder. Researcher Jeff Lukas, who authored the briefing, says water managers throughout the Colorado River watershed should brace themselves for diminished streams and the decreasing likelihood of filling the reservoirs left depleted at the end of 2018.
