Two major announcements could come Tuesday. The first is a forecast from the US Bureau of Reclamation that could trigger the first-ever Tier 2 water shortage for the Lower Colorado River Basin. The second is the bureau’s next step in its demand that the seven states in the river basin come up with a way to voluntarily cut up to 25% of their water usage, or the federal government will do it for them.
Tuesday’s report is all but certain to show Lake Mead will be below 1,050 feet come January — the threshold required to declare a Tier 2 shortage beginning in 2023. The question is how far below that threshold it will be. If the forecast is below 1,045 feet, which recent forecasts would suggest it will be, then mandatory water cuts will expand beyond Arizona, Nevada and Mexico and into California for the first time.
But the growing concern is that the mandatory cuts — a system that was updated as recently as 2019 — aren’t enough to save the river in the face of a historic, climate change-driven drought. States, water managers and tribes are now back at the negotiating table to figure out how to solve the West’s water crisis.
“We thought we were good, but the last few years have been so dry that we realized those tier reductions weren’t enough and aren’t enough,” Bill Hasencamp, the Colorado River resources manager with the Metropolitan Water District of Southern California, told CNN. “So the two things we’re focused on is how do we get through the next three years without the system crashing, and then how do we develop a long term plan to sustain the Colorado River.”
‘There’s only so much water’
There was one major problem: Having been written in the 1920s, at a time when precipitation was higher than normal, the pact overestimated how much water the Colorado River carries. It also did not account for the West’s Booming population growth and its hotter and drier future in the face of the climate crisis.
At a June Senate hearing, Bureau of Reclamation chief Camille Touton laid out a Stark warning. In order to stabilize the Colorado River Basin, states and water districts must come up with a plan by August 15 to cut 2 to 4 million acre-feet of water usage by next year. (An acre-foot is the amount of water that would fill one acre a foot deep — roughly 326,000 gallons.)
Touton’s proposed cut is a massive amount — the high end of the target is about 25% less water than states currently receive. And the low end of the target represents the vast majority of Arizona’s annual allotment of Colorado River water.
Touton also made it clear in June that if the states cannot come up with a plan, the federal government will act.
“It is in our authorities to act unilaterally to protect the system, and we will protect the system,” she said at the time. “We need to see the work. We need to see the action. Let’s get to the table and Let’s figure this out by August.”
But inter-state negotiations are not going well.
John Entsminger, the general manager for the Southern Nevada Water Authority, told CNN that so far not enough of the stakeholders have put forward proposals that would get the Basin to Touton’s target. He said he hopes the federal government proposes “some pretty strong measures” that could be acted on immediately.
“Frankly, I’m frustrated because the overwhelming sense I’ve gotten from the negotiations is there aren’t enough people taking this seriously enough and understanding this is about adapting to less water in this river,” Entsminger said.
Nevada has already moved to cut its Metropolitan water usage, banning non-functional turf and paying people for years to remove water-intensive lawns, Entsminger said. But agriculture, which takes up a lot of the water from the river, must be part of the equation as well.
“You have to have a contribution from the sector that uses 80% of the water,” he said. “That’s not law, politics, it’s just math.”
Entsminger said other stakeholders who are hesitant to give up their water allotments need to accept a new reality: The river is running dry, and sacrifices must be made.
“It doesn’t matter what can be agreed to because there’s only so much water, and mother nature will figure this out at some point,” he said. “At some point, there’s just no water in the river channel.”
The federal government has not often stepped in and taken control of water management plans from the states, but it has the authority to do so in the Lower Colorado River Basin — which includes Arizona, southern Nevada and southern California. And experts told CNN the Threat of federal action is something states will respond to.
“We kind of need the federal government to make some threats to spur action,” John Fleck, a Western water expert and Professor at the University of New Mexico, told CNN earlier this year. “Progress seems to happen when the federal government comes in and says to states, you need to do this or we’re going to do something you don’t like.”
