Federal officials announce water cuts in California, Nevada and Arizona as Colorado River supplies continue to plunge

Federal officials announced sharp water cuts for the next two years on Friday for three Western states that rely on the imperiled Colorado River.

Under the Bureau of Reclamation’s plan, California, Nevada and Arizona will collectively reduce water use by 1.25 million acre-feet (about 1.54 billion cubic meters) annually during that period, with the possibility of larger cuts depending on conditions.

Arizona will see the biggest cuts, while states upstream – Colorado, Utah, Wyoming and New Mexico – do not face any for now.

Meanwhile neighboring Mexico will reduce its intake by 250,000 acre-feet (about 310 million cubic meters) under a U.S.-Mexico treaty.

“We’ve been in this 26-year prolonged drought period,” said Andrea Travnicek, the Interior Department’s assistant secretary for water and science. “We continue to see a prolonged drought in our future. So continuing to work together as a whole within the basin is going to be extremely important.”

The current rules governing the use of the river’s water are set to expire in October, and the seven states have been unable to reach a consensus on sharing it over the long term.

Last winter saw the worst snowpack on record for the Colorado River Basin, adding more stress on farmers, industry, wildlife and hydropower producers, as well as tens of millions of people who rely on the waterway, including in dozens of Native American tribes and in two Mexican states.

Years of overuse combined with drought and rising temperatures due to climate change have depleted the country’s two largest reservoirs, which are both fed by the Colorado. Lake Mead recently plummeted to its lowest level since it began filling nine decades ago, and Lake Powell did the same about a week later. Their combined storage is the lowest it has been in nearly seven decades.

Negotiators in Arizona thanked California and Nevada for their collaboration on sharing the cuts.

“For 2027 and 2028, the reductions that are now memorialized here will provide substantial stability for folks,” said Tom Buschatzke, Arizona Department of Water Resources director. “We’ll continue to negotiate and figure out how we’re going to operate over a longer-term period, which is what we all want.”

JB Hamby, California’s chief Colorado River negotiator, said the plan brings “some badly needed near-term certainty at a moment of extraordinary risk,” though he called it “a bridge, not a permanent solution.”

Officials in Nevada applauded their collaboration with Arizona and California and said a seven-state consensus remains their preferred path for the river.

In Southern Nevada, Kyle Roerink, senior adviser at the conservation group Great Basin Water Network, said efforts to build a new airport and shopping malls and some public land sales have not progressed, reflecting the dire hydrology inked in the federal documents. Further cuts could slow real estate development in metro Las Vegas, he said.

“When the Hoover Dam, a symbol of American fortitude and American power, drops and loses its shine, it can be scary,” Roerink said. “But it can also pose itself as a great opportunity for us to prepare for the next hundred years in a meaningful way.”
