Bonnie Colby and Zoey Reed-Spitzer: Access to water, a concern around the globe, is constrained in many areas of the Colorado River Basin (CRB) by water scarcity, pollution and lack of delivery and treatment infrastructure. These constraints disproportionately affect the basin’s Native American, Hispanic and Black populations, groups which often have lower access to resources …

California’s projected use of Colorado River water this year, 3.76 million acre feet as of Reclamation’s Oct. 29 modeling runs, would be, as near as I can tell, the state’s lowest use since 1949. Also notable: Nevada’s 197,280 acre feet would be the lowest since 1992. The two lowest years in Imperial Irrigation District’s history …

Reclamation’s recently released September 24-Month …
By Jack Schmidt,1 Anne Castle,2 John Fleck,3 Eric Kuhn,4 Kathryn Sorensen,5 Katherine Tara,6 While Colorado River Basin attention is focused on negotiating post-2026 operating rules, a near term crisis is unfolding before our eyes. If no immediate action is taken to reduce water use, our already-thin buffer of storage in Lake Powell and Lake Mead …

With the latest Bureau of Reclamation model runs highlighting the serious risks posed by the declining reservoir levels that Utah State’s Jack Schmidt has been warning about, there are signs that the closed-room discussions among the seven basin states, after brief glimmers of hope last month, are once again not going well. The Reservoirs The …
