March 1985: when everything on the Colorado River changed

Brett Walton had a great bit of business in yesterday’s Circle of Blue story on 2019’s remarkable drop in Colorado River Lower Basin water use: The last time water consumption from the river was that low was in 1986, the year after an enormous canal in Arizona opened that allowed the state to lay claim …

The risk of Southern California falling into “perfect drought”

Last year was, for Southern California water management, perfectly wet. By that I mean a good snowpack in the Sierra Nevada and the Colorado River Basin. I’m stealing a wonderful phrase here from a new paper by the University of Arizona’s Connie Woodhouse (the full paper’s behind a paywall): “A Long View of Southern California …

Imperial Valley resident (and Imperial Irrigation District board member) Jim Hanks: The Salton Sea is a real place to me and I have always seen it as a lake, because that’s what it is. I also see it as hydrologically, geographically and morally connected to the Colorado River, and I appreciate the effort to place …

How Parker Dam might have been the Colorado River’s first

If you want to dam rivers, as we were inclined across much of the 20th century, the location of the current Parker Dam on the Lower Colorado River makes sense – a narrow gap just downstream from the confluence of the Colorado and Bill Williams rivers on the Arizona-California border. I paid a visit last …
