Hiroko Tabuchi has a fascinating piece in this morning’s New York Times about a battle underway to determine whether gazillions of dollars in infrastructure spending to upgrade America’s municipal plumbing is spent on iron or plastic pipe. It features a couple of issues I love to talk about with our University of New Mexico Water …

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 …
Scientists for many years have projected a decline in the Colorado River’s flow as a result of a warming climate. But it’s only in the last couple of years that we’ve begun to see evidence that this is already happening. The system has a lot of natural variability, so detecting the relatively smaller impact of …

A little “field work” yesterday morning, with one of our University of New Mexico Water Resources Program graduate students and a faculty colleague, looking at a potential environmental restoration site we’re studying. The only way to get there was by bicycle. Bummer.
Pasadena, California, wants to use treated effluent to water golf courses. This is a water policy no-brainer, right? Well…. “As part of preparations to commence deliveries of recycled water to Pasadena, the city of Glendale petitioned the State Water Resources Control Board to seek their approval for a reduction in the amount of treated wastewater …

If you had asked me to guess whether public or private utilities did better at water conservation, I would have without hesitation guessed that public utilities did better. So here’s a fascinating result from Manny Teodoro and Youlang Zhang of Texas A&M, looking at data from the recent California drought: [O]n average, communities served by private utilities …
An example of what can happen when folks stop fighting over water and search for common ground paths: Now, instead of a wide shallow creek, the low-flow Fraser River drops into a narrow channel that allows to run deeper, faster and colder. That led to a nearly immediate rebound in the fish population, according to …

California has seen excellent groundwater recovery in the last year, according to a report last week from the California Department of Water Resources: But it’ll take more than a year to dig out of the hole left by the massive groundwater pumping of the last 6 years: From the report: While images of filling reservoirs …
