Natalie Rogers did a nice writeup for the University of New Mexico on some work I’m doing with a group of University of New Mexico colleagues on climate change impacts and adaptation in New Mexico. Working as part of a new affiliation between UNM researchers and the USGS-funded South Central Climate Adaptation Science Center, some …

Eric and I could not be more happy about this from John Berggren. There are countless Colorado River resources available to learn about the history of how the river has been and continues to be governed. Hundreds of books, reports, studies, and papers have been written on the subject. Accordingly, it takes something quite new …

We’re diving into a semester studying (and modeling) Colorado River management in the University of New Mexico Water Resources Program. We’ve got a smart group of next-generation water managers, and we’ll be using the Goldsim modeling platform to build some system models. The students will be helping me think through the set of questions folks …

One of the things I do with the students in my University of New Mexico Water Resources classes is try to develop the habit of paying attention, through repetition, to the available data on the systems we’re talking about. We use USGS river gauges to do this – checking the gauges is a classroom routine. …

A member of the Colorado River brain trust argues that when you use reservoir elevation to define an action level of some sort, the reservoir remarkably ends up hovering around that level. The updated annual USBR Lake Mead elevation chart, just published with the 2019 data, nicely illustrates their point. The 2007 Interim Guidelines set …

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 …

Laura Paskus asked a bunch of interesting questions about our new book Science Be Dammed and I did my best to try to answer them for New Mexico PBS’s In Focus/Our Land last Friday:
Happy to report that my friend Sharon Megdal, head of the University of Arizona Water Resources Research Center and a member of the Central Arizona Water Conservation District Board, has been honored with the University Council on Water Resources Warren A. Hall Medal. Sharon’s a wonderful example (and role model for me as a new …
Despite an above-average snowpack in significant parts of the Colorado River Basin, the initial 2020 forecast is for below-average runoff thanks to a dry summer and fall. According to the Colorado River Basin Forecast Center’s Cody Moser, speaking in today’s first-of-2020 forecast briefings, the monsoon over the Colorado River Basin was the 9th driest and …

The folks running Lake Mead’s marina – often a story line for folks like me writing about a declining western water supply as marina managers chase a shrinking reservoir’s shoreline – are running the opposite direction this year: In 2003, they had to relocate the marina to the south 12 miles because the water was …
