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 …
If we’re not allowed to divert some of this water, then Arizona continues to get it all, and they become wealthier and wealthier as time goes by. That’s Darr Shannon, head of the government entity hoping to build a diversion to take water out of New Mexico’s bits of the Gila River. From a fascinating …

If you want to dam rivers, as we were inclined across much of the 20th century, the location of the current Parker Dam on the Lower Colorado River makes sense – a narrow gap just downstream from the confluence of the Colorado and Bill Williams rivers on the Arizona-California border. I paid a visit last …

In the wake of Arizona’s difficulties in coming to terms with the future of central Arizona agriculture as it sorted out its approach to reducing Colorado River water use under the Drought Contingency Plan, the latest Census of Agriculture data is fascinating.

A letter this afternoon from Arizona Department of Water Resources Director Tom Buschatzke to Central Arizona Project board members, also circulated to Arizona’s Drought Contingency Plan Steering Committee, suggests another hangup in Arizona’s efforts to agree on a plan to reduce its Colorado River water use. It involves the distinction between using water from on-river …

I’m moderating a panel on the Lower Basin Drought Contingency Plan at this year’s meeting of the Colorado River Water Users Association in Las Vegas (NV) in a couple of weeks. What shall we talk about? Arizona’s water agencies, cities, farmers and tribes haven’t quite sealed a Colorado River deal. But they’re getting closer. The …

Update: via Ian James from the Arizona Republic, here are the slides for today’s meeting. Previously: With the announcement of a meeting this afternoon of Arizona’s Lower Basin Drought Contingency Plan steering committee, it appears we have the general shape of an agreement to settle the thorny issue of how to reduce Arizona’s use of …
