Why it’s not about the Bellagio Fountain redux – a peek into the solution space

Posted by on

Here’s The Nature Conservancy’s Brian Richter, in his new book Chasing Water, describing what the solution space for the Colorado River Basin’s water problems might look like:   Even though urban water uses (for domestic, commercial, and industrial purposes) account for only a minor share of total water use in most water-stressed places, urban water …

Colorado River history pic Sunday: If you don’t measure it, you can’t manage it

Posted by on

I love this picture. E.C. LaRue was a U.S. Geological Survey hydrologist who in 1916 assembled the first attempt at a rigorous scientific survey of the water resources of the Colorado River Basin. Water Supply Paper No. 395 will never be mistaken for great literature. LaRue was one of America’s early technocrats, intellectual ancestors of …

Lake Mead’s problem: It’s about the lower basin structural water deficit, not the Bellagio Fountain

Posted by on

tl;dr Vegas is an easy target, but Lake Mead’s problems involve far more than Sin City’s profligacy. Longer version: As Lake Mead drops toward a record low some time next month, there’s a temptation to draw a dotted line to the Bellagio Fountain, 30 miles to the west, and point a finger of blame. It’s …

In the West, what used to be snow, falling as rain

Posted by on

If I was trying to manage water in California, these maps would give me the heebie-jeebies. It’s from a new paper (AGU-walled) by Zion Klos and colleagues extending our knowledge of the shift from snow to rain in the high country of the western United States as a result of warming temperatures. Here’s why this …

Steamboats and pickup trucks in the Colorado River

Posted by on

A century and a half ago, there was enough water in the Yuma stretch of the Colorado River to sink a steamboat: On this date in 1854, the first steamer on the Colorado River, The Uncle Sam, sank at Pilot Knob. Today, it’s pickups, stuck in the sand: Yuma Station agents patrolling near the Colorado …

South of the border, tension about highest and best use of Colorado River water

Posted by on

Preparing a talk I’m giving next week about Minute 319, the Colorado River environmental pulse flow and its broader implications for western water management, I ran across this new piece by environmental journalist Cesar Angulo about the mixed feelings in Mexico about the effort: According to Arroyo Gonzalez, these reforestation projects have a very positive …

Arizona goes all in on its Lower Colorado risk move

Posted by on

Michael Wines of the New York Times joins the discussion as Arizona officials continue to push their new message about the risk of shortage on the lower Colorado: Although experts have been aware for years that shortages would eventually occur, the analysis represents a marked turnabout in officials’ thinking. “We’re dealing with a very serious …
