If trends continue, Phoenix is on a path to groundwater “safe yield”, according to new research

If past trends in greater Phoenix – agricultural land transitioning to urban – the area is on track to groundwater “safe yield”, according to new research by an Arizona State University team: Under (business as usual) conditions where population is expected to increase and agricultural activities to gradually decrease, our results indicate a reduction in …

Imperial Irrigation District’s line in the Salton Sea sand

The Imperial Irrigation District board will take up a resolution this afternoon drawing a sharp line. If action isn’t taken to deal with the Salton Sea, the historic early-2000s deal that attempted to untangle California’s Colorado River overallocation (the “Quantification Settlement Agreement” or QSA) “will have been breached”: The full text of the resolution and …

New paper with Anne Castle on Risk of Colorado River curtailments in Colorado, Upper Basin

The framing questions I’ve used for my work on water over the last decade go something like this: When the water runs short, who doesn’t get theirs? What does that look like? Those are the motivating questions behind a new paper Anne Castle and I have written. We’ve also added an increasingly important third question: …

How much might Utah’s Lake Powell pipeline cost?

My Colorado River policy attention time is a finite resource, and I admit I’ve not paid terribly close attention to Utah’s Lake Powell Pipeline proposal. My reasoning has been that it’s likely so expensive relative to the water it would provide that, with the end of big federal subsidies, Utah’s eventually going to wake up …

From “The Great Mistake” to “Science Be Dammed”

When I was wrestling six years ago with a path through what became my book Water Is For Fighting Over, I collected material about what I came to call “the great mistake” – the overallocation of the Colorado River’s water. One of my favorite stories surrounded William Sibert: It is quite probable that the compact …

More Colorado River “grand bargain” buzz

There was more buzz this week at two big Colorado River Basin events about the idea of a “grand bargain” to deal with coming collisions between water overallocation and the Law of the River. The idea crept into the title of the Water Education Foundation’s 2019 Santa Fe Symposium – “Can We Build a Bridge …
