Hey Tucson, I’ll be yammering at the University of Arizona Thursday

Posted by on

Thursday at 4: With another dry year setting in across the West, the challenges of meeting the water supply needs of a growing population while maintaining our rural communities and a healthy environment are again being thrown in sharp relief. The continuing decline of Lake Mead has become a symbol of deepening problems, but there are also …

#tbt to that time New Mexico tried to demand a Gila River Compact

Posted by on

For today’s #tbt (Throwback Thursday), a return to the remarkable era of Steve Reynolds in New Mexico water management, and that time Reynolds tried to give New Mexico an effective veto over the Central Arizona Project. Students in this year’s UNM Water Resources Program spring class are doing a case study this year on New …

Overcoming “use it or lose it” on the Colorado – an example

Posted by on

Yesterday I pointed out how much water is being stashed in Lake Mead as an example of how folks on the Colorado River are overcoming the old “use it or lose it” problem in western water. Here’s another example, this time with water taken off of the river and stored underground, in this case excess water …

Looking for flexibility within Arizona

Posted by on

Arizona’s current internal political struggles over allocation and management of shortage on the Colorado River illustrate a central dilemma in the basin’s transition from the era of managing development of the river’s water to the era of managing scarcity. While we generally have demonstrated the ability to use less water across a range of water …

Arizona misters and the value of water

Posted by on

When we think today about Arizona’s water problems, we imagine large lawns in sprawling suburbs in and around Phoenix, golf courses, and “misters”—those devices that fritter away water into the hot desert air to cool the customers eating at outdoor restaurants in the Valley of the Sun. Me, in Water is For Fighting Over Lissa …

loss aversion and the latest Lake Mead forecast

Posted by on

The Bureau of Reclamation’s June Colorado River forecast projects Lake Mead ending 2018 at elevation 1,076.5 feet above sea level, three feet higher than the Bureau’s January projection of 1,073.5. If the forecast holds, that’s enough of an increase in Mead storage, thanks to a larger-than average snowpack in the Rockies, to avoid a shortage …

The Phoenix City Council today agreed to pay the Gila River Indian Communities $2 million as part of a deal to leave 40,000 acre feet of the Indian Communities’ Colorado River water in Lake Mead this year. The state of Arizona, the federal government, and the Walton Family Foundation also are contributing. From the city …

Using less water on the Lower Colorado River

Posted by on

At the end of April, Lake Mead sat at 1,085 feet above sea level, more than eight feet higher than it was a year ago. That is in part thanks to a big winter upstream, which has ensured continued above-average releases from Lake Powell upstream. But equally important is the fact that folks in the …

who’s in charge of Arizona’s Colorado River water?

Posted by on

The feud within Arizona over who’s in charge of the state’s Colorado River water – the state Department of Water Resources or the Central Arizona Water Conservation District – escalated this week. This is from an April 25 “cease and desist” letter (obtained by me through a state public records act request) from the Arizona …
