I love this picture of what I can only assume are three rascals defying their mothers and swimming in the New River, in the Imperial Valley of Southern California in 1905. The New River, in the incarnation seen here, was formed when the Colorado River ate through a poorly built intake structure and chewed up …
Without pack animals and before fueled machinery, the ability of a human to carry food placed a fundamental constraint on economic integration across large distances. Over any significant distances, a human would have to eat all the food they could carry, leaving none left for trade. Trade of small, high value items could go on …
In an interview over at Grist, Brad Udall reminds us that, as we think about the effect of climate change on the West, it’s not just the thorny question of whether precipitation rises or falls that matters. Despite the uncertainties surrounding that question, as temperatures rise (a projection about which there is considerably less uncertainty), …
One of the central struggles in moving water out of the Colorado River a century ago was the silt. Moving water moves a lot of it, and when you slow the water down, the silt drops out. It was siltation that kept clogging Charles Rockwood’s Imperial Valley diversions, where he was taking water from the …
My on-again, off-again infatuation with 1083.57, the elevation Lake Mead reached in March 1956, is back on. As Shaun McKinnon reports in this morning’s Arizona Republic, Mead’s at the lowest it’s been since then. The latest “24-month study” from the Bureau of Reclamation (pdf), out this week, is back to forecasting that we’ll drop below …

Between the USGS, the Bureau of Reclamation, the Library of Congress, Calisphere and others, there are so many great old Colorado River photos around that it’s easy to think the early history of the river’s development happened in black and white. I get lost in them. Today’s treasure is a photo from the 1923 Birdseye …

When I was in Vegas in April, I heard several talks on the way folks on Lake Mead engage in a practice they call “chasing water”. As the water storage reservoir recedes, the Park Service extends boat ramps farther and farther. The owners of the Las Vegas Marina, which used to sit up in Las …
You would think that on the over-appropriated Lower Colorado River, downstream from dwindling Lake Mead, getting by on less water would be a good thing. But this little news blurb from KXO radio in El Centro, in California’s Imperial Valley, suggests otherwise. The problem, apparently, is that the Imperial Irrigation District, the largest water rights …

Michael Campana prodded me a bit this morning on Waterwired regarding a discussion happening here and elsewhere about the possibility of abandoning Phoenix as the place runs out of water. It’s a strong meme, and it comes up frequently among those who recognize the fragile nature of cities of the desert southwest as growth-fueled water …

update: An eagle-eyed friend points out that when I grabbed this from the original PowerPoint slide, I clipped off the X and Y axis legends. That’s time on the X axis – 1920ish to 2006, and millions of acre feet on the Y axis. xxxxx ‘Cause I love the old pictures, and since it came …
