The federal drought dollars were a crucial component of those negotiations.
“This is now a major, major problem,” said Sen. Mark Kelly (D-Ariz.), who has sent multiple letters to Interior Secretary Doug Burgum on the freeze of payments from a $4 billion pot in the Inflation Reduction Act that has been going to pay cities, farms and tribes to forgo water deliveries and funding major infrastructure projects that conserve water over the long term.
‘Terrible consequences for the entire Basin’
The 10,000 acre-feet that the Gila River tribe withdrew last month is a drop in the bucket of Lake Mead, the country’s largest reservoir, on the Arizona-Nevada border. But in the arcane world of Western water, it was a shot across the bow.
“We have given the Department every opportunity to avoid what would be a calamitous break in our longstanding partnership, with terrible consequences for the entire Basin,” Stephen Roe Lewis, the community’s governor, wrote to Burgum on Feb. 11 before pulling the water from Lake Mead and moving it to a storage facility in Arizona.
The move worked. Interior unfroze the tribe’s funding Feb. 19.
An Interior Department spokesperson said the agency is “dedicated to providing life-sustaining water and harnessing the significant hydropower the river offers.”
“We are actively engaging in dialogue with the Colorado River Basin partners as we work towards long-term operational agreements for the river after 2026. Throughout this effort, we remain committed to ensuring fiscal responsibility for the American people,” the agency spokesperson said in an emailed statement.
So far, the Gila River tribe is the only entity to withdraw water. But 40 percent of the supplies in Lake Mead are owned by cities, farms and tribes, so if other entities started pulling water, reservoir levels could quickly fall. That would trigger draconian cuts to the states in order to ensure that Hoover Dam doesn’t lose the ability to generate hydropower and make downstream deliveries.
The Trump administration’s chaos is jarring the officials responsible for ensuring that water keeps flowing to cities, farmers and tribes.
“We’re in an increasingly uncertain world,” said Tom Buschatzke, director of Arizona’s Department of Water Resources.
Impact on state negotiations
The Colorado River has long been prone to battles, thanks to a century-old mistake that promised the states more water than it actually supplies. But as climate change has shriveled the river’s flows — scientists estimate they’ve dropped by 20 percent over the past 25 years — the states have opted to cooperate to keep the river flowing rather than fight over who gets its diminished returns.
