Yesterday I pointed out how much water is being stashed in Lake Mead as an example of how folks on the Colorado River are overcoming the old “use it or lose it” problem in western water. Here’s another example, this time with water taken off of the river and stored underground, in this case excess water …

The “use it or lose it” problem in western water happens when water users who conserve are penalized by having the saved water simply go to another user. A series of policy innovations over the last decade to overcome this problem are showing up right now in a big way in Lake Mead. In all, …

As I mentioned, this is the driest start to a water year in a century in Albuquerque. The preliminary Jan. 1 runoff forecast from the federal Natural Resources Conservation Service bears this out. The forecast, based on snow measurements, is stark. NRCS has 40 years of snow records, and for many sites, this is the …
The last time we had any measurable precipitation at Albuquerque’s airport weather station, where we keep the records, was Oct. 4. That’s 90 days, the driest start to a water year since 1917-18.
Lake Mead ends 2017 at elevation 1,082.5, almost two feet above last year at this time. Lake Powell ends the year at 3,623, up more than 20 feet from a year ago. Combined storage in the two primary Colorado River reservoirs ends the year up more than 2 million acre feet. This is in part …
In the summer of 1931, as the Bureau of Reclamation was launching work on Hoover Dam, flows on the Colorado River dropped to what, at the time, were low flows unprecedented in the few decades’ records on the river. In retrospect it should have been a clue that there was not going to reliably be …

We’re up to 82 consecutive days without measurable precipitation at the Albuquerque airport, the 8th longest dry streak in more than a century of record keeping. And there’s nothing in the forecast out seven days, which is as far as it’s reliable to take it (butterfly effect and all). But OK, since you asked, the …
LAS VEGAS, NV – When I stopped at Boulder Harbor on Lake Mead Tuesday morning as I drove into Las Vegas, I saw this field of salt cedar taking hold on what had been a mud flat left by Mead’s declining water levels. It’s a clumsy metaphor for what happens when you get comfortable with …

LAS VEGAS, NV – “Dry for Decades,” the tourist placard at Hoover Dam’s Nevada spillway says. “The last time the waters of the Colorado River flowed through this spillway was in 1983.” On my way to this year’s annual meeting of the Colorado River Water Users Association, I spent some time yesterday at Hoover Dam …
