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, …

Let’s look at the new Colorado Basin River Forecast Center graphic of projected runoff into Lake Powell, shall we? The folks at CBRFC has done a lovely update of their graphical presentation. The story it’s telling right now – not so lovely. Let’s take this step by step. First, the green lines in the middle …

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 …

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 …

tl;dr Western water policy and politics has to come to grips with the fact that overall water use is declining, not rising, as populations and economies grow. The longer version…. Two years ago, when I was deeply immersed in the act of writing my book, I had an incredibly important conversation with Emily Turner, my …

The latest USGS data on water use by U.S. municipalities shows a continued decline, despite a growing population. This not just a decline in per capita use, though it is that. But per capita use continues to drop faster than population is rising in most areas. Brett Walton has a nice summary of the findings, …
Consumptive use of Colorado River water by the states of the Lower Basin (Nevada, California, and Arizona) is on track this year to be at its lowest since 1986. This graph, which I put together this weekend for a talk I’m giving at the Upper Colorado River Basin Water Forum at Colorado Mesa University in …

One of my favorite bits of business that never made it into my Colorado River book was a late afternoon encounter at Lake Mead’s Boulder Harbor boat ramp with a guy named Scotty. I was thinking about Scotty when I came across the image below, in a 1946 Bureau of Reclamation report on the development …
