  • OpenET: Balancing Water Supply and Demand in the West October 14, 2024
    At the end of 2022, 65 percent of the Western United States was in severe drought, the result of a two decades long mega drought in the Colorado River Basin that had captured headlines around the world.  However, it was flooding, not drought, that was making headlines when we began our research for this story […]
