FLAGSTAFF, Ariz. — The Interior Department announced Friday that it will consider revising a set of guidelines for operating two major dams on the Colorado River in the first sign of what could lead to federal action to protect the once-massive but shrinking reservoirs behind them.
The public has until Dec. 20 to weigh in on three options that seek to keep Lake Mead and Lake Powell from dropping so low they couldn’t produce power or provide the water that seven Western states, Mexico and tribes have relied on for decades.
One of the options would allow the Interior Department’s U.S. Bureau of Reclamation to take unilateral action, as it threatened this summer when it asked states to come up with ways to significantly reduce their use beyond what they have already volunteered and were mandated to cut.
“The Interior Department continues to pursue a collaborative and consensus-based approach to addressing the drought crisis afflicting the West,” Interior Secretary Deb Haaland said in a statement. “At the same time, we are committed to taking prompt and decisive action necessary to protect the Colorado River System and all those who depend on it.”
The announcement comes more than four months after Reclamation Commissioner Camille Touton told Congress that water use must be cut dramatically as drought and overuse tax the river — an essential supply of water for farmers, cities and tribes in the U.S. West, as well as Mexico.
The seven states that tap the river failed to reach Touton’s August deadline and have been working ever since to reach a compromise. It now appears unlikely a grand deal will be reached. In the meantime, the bureau has offered billions in federal money to pay farmers and cities to cut back.
But Interior’s new action marks the first time it’s taking a clear step toward imposing its own mandatory cuts. The agency anticipates changes to the conditions at which water shortages are declared in the river’s lower basin. Lake Mead and Lake Powell were about half full when the 2007 guidelines were approved and are now about one-quarter full.
The other two options under the Bureau of Reclamation’s plan are to let states, tribes and non-governmental organizations reach consensus, or do nothing, which is a standard alternative in environmental impact statements.
The bureau expects to produce a draft next spring based on public input. A final decision could come in late summer of 2023 around the time the bureau announces any water cuts for the following year.
The 2007 guidelines and an overlapping drought contingency plan approved in 2019 were meant to give states more certainty in their water supply. For the lower-basin states — California, Arizona and Nevada — the agreements set elevation levels at Lake Mead on the Arizona-Nevada border at which they are subjected to mandatory and voluntary reductions. Mexico also shoulders cuts.
Water users have been delayed in renegotiating the agreements that expire in 2026 because the drought and climate change have forced quicker action.
Nevada, Arizona and Mexico will have to cut their water use in 2023 for a second year in a row under existing agreements. California is looped in at lower elevations in Lake Mead. Arizona was forced to give up 21 percent of its total Colorado River supply. Farmers in central Arizona, tribes and growing cities like Scottsdale, Ariz., are feeling the impacts.
Tom Buschatzke, director of the Arizona Department of Water Resources, said he’s been hoping the bureau would require cuts from water users rather than rely on voluntary action. But he also warned that the prospect of mandatory cuts could make it less likely that farms or cities will choose to give up some of their water, calling it a “zero-sum game” of sorts.
Still, anything that results in savings is a worthwhile action, he said.
“The situation in my mind is so dire, we’re so close to the edge,” he said in a recent interview.
The department declined further comment Friday, and the Southern Nevada Water Agency didn’t respond to a request for comment. Chuck Cullom, executive director of the Upper Colorado River Commission, said he was still evaluating the announcement but appreciated the bureau taking action.
Bill Hasencamp, manager of Colorado River resources for the Metropolitan Water District of Southern California, said he hopes the threat of cuts will inspire users to offer up more savings now while federal money is available to pay for it. The district supplies water to nearly 20 million people and counts on the river for a third of that water.
“The more you can do now with compensation is going to reduce the chance of being cut back without it,” he said.
Under one payment option, water users can be paid up to $400 per acre-foot of water (325,850 gallons) left in Lake Mead. So far only the Gila River Indian Community in Arizona has publicly expressed interest in that option, saying it will conserve up to 125,000 acre-feet of water (40.7 billion gallons) on its reservation and offer another 125,000 acre-feet of water stored underground to cities annually for the next three years.
Farmers in California and Arizona say that’s not enough money to cover losses if they leave fields unplanted or to pay for things like installing more efficient irrigation systems. They plan to apply for money through a different option that allows them to name their price — and justify why they deserve it.
A third pot of money would offer payment for larger projects aimed at achieving long-term water savings, like ripping up decorative grass in urban areas or building small, on-farm storage systems that make it easier for farmers to bank water rather than lose it to runoff.
The bureau says water users who take the $400 payments may be prioritized for that money over users who want more for short-term conservation.
California’s water users have offered to conserve up to 9 percent of its river water. That’s contingent on adequate payment and help for the Salton Sea, a drying lake bed fed by farm runoff.
