Let’s start with the Colorado River because it’s in the news. The federal government has put some extraordinary numbers out there, suggesting water users cut between 2 and 4 million acre-feet of water usage starting this year — roughly 40% of the entire river’s recent flow. How could that possibly happen?
It’s going to be really hard. We’re looking at drastically reduced food production and the migration of agriculture to other parts of the country and real limits on growth, especially in desert cities like Phoenix. My fear is that groundwater will, as usual, be left out of the discussion — groundwater is mostly unprotected, and it’s going to be a real shit show.
Remind us how that happens. States and farmers cut back on the Colorado River, and California and Arizona just start pumping all the water out of their aquifers?
Yeah. This started with the drought contingency plan [the 2018 legal agreement among the states on the Colorado River]. Arizona had to cut nearly 20% of its Colorado River water. To placate the farmers, the deal was that they would have free access to the groundwater. In fact, something like $20 million was allocated to help them dig more wells. So, it was just a direct transfer from surface water to groundwater. Right away, you could see that the groundwater depletion was accelerating. With this latest round, I’m afraid we’re just going to see more of that.
