“This is what climate change + an out-dated law of the river looks like: ‘There’s a problem of aridification. But on top of that, there’s a problem with the rules…The rules governing the system are not sustainable.’ — Jonathan Overpack via Twitter

The river’s biggest water user, California, didn’t join six states in a proposal to cut some 2 million acre feet of usage

For the second time in six months, states that depend on the Colorado River to sustain their farms and cities appear to have failed to reach an agreement on restricting water usage, setting up the prospect that the federal government will make unilateral cuts this year…

“Obviously, it’s not going swimmingly,” said Jeffrey Kightlinger, the former general manager of the Metropolitan Water District of Southern California, a water provider that is a major player in the talks. “It’s pretty tough right now.”

[…]

The proposal by the six states — Arizona, Colorado, Nevada, New Mexico, Utah and Wyoming — seeks to protect the major reservoirs in Lake Powell and Lake Mead from falling below critical levels, such as when the dams would no longer be able to generate electricity or at “dead pool,” when water would effectively be blocked from flowing out of these lakes. Before above-average snows in recent weeks, the Bureau of Reclamation was projecting that Lake Powell could start to reach such thresholds by this summer.

One of the central tensions of these complicated negotiations is how to balance cuts between farming regions against those in cities, including major population centers. Agriculture uses some 80 percent of the river’s water and also tends to have the most senior rights, some dating back to the 19th century. The way this “priority system” works, residents of Phoenix would lose water before vegetable farmers in Yuma. Those who grow alfalfa in Southern California’s Imperial and Coachella valleys would keep their water before people in parts of Los Angeles.

Kightlinger, along with many other water experts and officials, says cuts of this magnitude and severity have to be shared, rather than doled out according to seniority.

“They can’t follow the priority system. That would be a disaster. That would be: We’re basically going to put all the cuts on the major share of the economy. That just simply can’t be reality,” he said.
