Do-or-Die Talks Reach Deal to Keep Colorado River From Going Dry, for Now


The Biden administration has negotiated an agreement among California, Arizona and Nevada to take less water from the drought-strained Colorado River, a deal that reduces, — for now, the risk of the river running dry below the Hoover Dam, which would jeopardize the water supply for Phoenix, Los Angeles and some of America’s most productive agricultural land.

The agreement, to be announced Monday, calls for the federal government to pay about $1.2 billion to irrigation districts, cities and Native American tribes in the three states if they temporarily use less water. The states have also agreed to make additional cuts beyond that amount to generate the total reductions needed to protect the collapse of the river.

Taken together, those reductions would amount to about 13 percent of the total water use in the lower Colorado Basin — among the most aggressive ever experienced in the region, and likely to require significant water restrictions for residential and agriculture uses.

The Colorado River supplies drinking water to 40 million Americans in seven states as well as part of Mexico and irrigates 5.5 million acres of farmland. The electricity generated by dams on the river’s two main reservoirs, Lake Mead and Lake Powell, powers millions of homes and businesses.

But drought, population growth and climate change have dropped the river’s flows by one-third in recent years compared with historical averages, threatening to provoke a water and power catastrophe across the West.

California, Arizona and Nevada get their shares of water from Lake Mead, which is formed by the Colorado River at the Hoover Dam and is controlled by the federal government. The Bureau of Land Reclamation, an agency within the Interior Department, determines how much water each of the three states receives. The other states that depend on the Colorado get water directly from the river and its tributaries.

The agreement struck over the weekend runs only through the end of 2026, and still needs to be formally adopted by the federal government. At that point, all seven states that rely on the river — which include Colorado, New Mexico, Utah and Wyoming — could face a deeper reckoning, as its decline is likely to continue.

The negotiations over the Colorado were spurred by a crisis: Last summer, the water levels in Lake Mead and Lake Powell, the two largest reservoirs along the river, fell enough that officials feared the hydroelectric turbines they powered might soon cease operating.

There was even the risk that reservoir levels would fall so low, the water would no longer reach the intake valves that control the flow out of the lakes — essentially drying up the river downstream.

Facing that prospect, the Interior Department last June told the seven states to find a way to reduce their water use by two to four million acre-feet of water per year. (An acre-foot is roughly as much water as two to three households use in a year.) The states failed to reach an agreement, even as water levels in the two reservoirs remained dangerously low.

That inertia led the federal government to lay the groundwork for unilaterally imposing cuts on those states. Adding to the pressure, the department said last month that it might disregard the century-old rules governing which states should bear the brunt of cuts and instead come up with a different formula.

The federal government gave states until May 30 to take a position on the prospect of unilateral reductions. But behind closed doors, the Biden administration was negotiating with states to reach a deal and avoid having to impose cuts that would certainly face legal challenges and end up delaying any action.

Under the agreement announced Monday, most of the cuts — 2.3 million acre-feet — would come from water districts, farm operators, cities and Native American tribes that had agreed to take less water in order to qualify for federal grants offered under the 2022 Inflation Reduction Act. Those payments will total about $1.2 billion.

Another 700,000 acre-feet would come from California, Nevada and Arizona, which agreed to work out the cuts among themselves in the coming months. If they don’t, the Interior Department said it would withhold the water — a move that could face legal and political challenges.

Together, the reductions would save three million acre-feet over the next three and a half years, above and beyond existing agreements. That is far less, on an annual basis, than what the federal government had demanded last summer.

The Interior Department was able to negotiate less drastic cuts thanks to an unusually wet winter provided snowpack levels in the Colorado Basin that are far above average, especially in California. That is expected to significantly increase the amount of water in the river, at least temporarily.

The terms of the deal were described to The New York Times by a senior official at the Interior Department who was involved in the negotiations, and who spoke on the condition that he not be identified by name. The Washington Post reported elements of the deal last week.

The structure of the agreement allows the Biden administration to sidestep, for now, the problem of which states will take the brunt of the cuts.

As a result, what looked until recently like a state-against-state cage match has produced an outcome that is more tolerable for the states involved, if not exactly welcome.

The rules that govern the river, which date to 1922, say that much of Arizona’s supply from the Colorado River would be cut to almost zero before California experienced reductions. Though Arizona would still see its water supply reduced significantly, the deal effectively removes the threat of drastic slashes.

California also fares better than might otherwise have been the case. The Interior Department raised the prospect of cutting each state’s supply equally, as a share of its total use. Because California uses more water from the Colorado than any other state, it would have lost the most — a shock to farmers in Southern California, as well as cities like Los Angeles and San Diego. Relying largely on voluntary reductions gets around that concern.

The deal is also a victory of sorts for the Biden administration, which has at times appeared unsure how to respond to the growing crisis. In the past year, it twice set deadlines for the states to come to an agreement, which they failed to meet. The department said the agreement shows that states are able to work together with the federal government to address the challenge of the Colorado’s decline.

That notion, too, will soon be tested. The Interior Department has said its next step will be to study the effects of the deal that states have struck, before deciding how to proceed. In the meantime, the next round of negotiations, about what to do after 2026, are set to begin next month.
