Ry Rivard in Voice of San Diego: As San Diego benefits from its new supplies of water, its customers are cutting their water use. That means San Diego now has more water than it needs. This is what I’m talking about Friday at the Law of the Colorado River conference. It’s the core of the …

The tamarisk beetle, introduced in 2001 as a strategy to control “invasive” tamarisk trees in the United States, is “expected to spread throughout the entire (Colorado River Basin), and tamarisk presence, distribution and abundance will likely decline as a result,” according to a new report (pdf). “Tamarisk beetle in the Colorado River basin”, written by Ben Bloodworth of …

I’ve begun putting scare quotes around “done”, but we just passed a major milestone deserving of the word – done – with my upcoming book on the problems facing the Colorado River Basin and what I think solutions might look like. The book is now fully edited and entering the production process at Island Press. And …
In freshman college physics, a common conceit to simplify the study of velocity and momentum is the air table (think air hockey), which allows you to reduce the friction on a moving object to negligible levels. “Imagine,” the professor explains, “a frictionless plane.” And then sketches out on the chalkboard the equations for velocity and …

I’m giving a talk next week at the CLE Law of the River conference in Las Vegas about what I think is one of the two most important trends in western water management. The first, which we hear a lot about, is the pressure posed by climate change and drought. The second, which I don’t think …

Note to self: remember that El Niño isn’t just about enjoying a growing southwestern U.S. snowpack and pondering its implications on our 2016 water supply. Across the horn of Africa (and many places around the world) people go hungry as a result. From SciDev.Net, a portal for global development issues: The consequences of a lack of …
From the San Luis Valley of southern Colorado, Rio Grande headwaters, more evidence that ag communities can overcome the groundwater tragedy of the commons: ALAMOSA — For the second year in a row, water officials have seen a recovery in one of the aquifers that farmers lean on heavily in the San Luis Valley. The …
