You can pull off on a section of road outside of Page, Arizona, and gaze down at the remnants of Lake Powell. The bleached ring surrounding the canyon walls is referred to by the locals as the “bathtub stain.” It indicates the former location of the water, which was occasionally a hundred feet higher than it is now. After a minute of standing there, the Western math no longer seems abstract. This river supplies water to seven states. Forty million individuals. Clearly, the river is unable to keep up.
The length of time that the warnings have been disregarded is difficult to ignore. Written during one of the wettest decades in the basin’s recorded history, the 1922 compact that divided up the Colorado was generous on paper but fictitious in reality. By the 1950s, engineers were aware of this. In the 1990s, hydrologists yelled about it. Lake Mead is currently at levels that were once thought to be catastrophic, and the federal government continues to issue shortage declarations that are difficult to implement.
| Subject Profile: The Colorado River Basin Crisis | Key Information |
|---|---|
| Region | American Southwest — serving seven U.S. states and parts of northern Mexico |
| River Length | Approximately 1,450 miles |
| States Dependent on It | Colorado, Wyoming, Utah, New Mexico, Arizona, Nevada, California |
| Population Served | Around 40 million people |
| Year of Original Compact | 1922 |
| Treaty With Mexico | Signed in 1944 |
| Annual Allocation (originally) | 16.5 million acre-feet |
| Actual Recent Flow | Closer to 12 million acre-feet — and falling |
| Largest Reservoirs | Lake Mead and Lake Powell, both at historic lows |
| Primary Water Use | Roughly 70–80% agriculture, mostly alfalfa and cattle feed |
| Key Federal Agency | U.S. Bureau of Reclamation |
| Most At-Risk Crops | Alfalfa, cotton, almonds, avocados (south of border) |
| Current Status | Tier-level shortages declared since 2021 |
The battles are no longer hypothetical. Arizona’s tier system has already resulted in cuts, and Pinal County farmers have seen their allotments drastically decrease. The most senior rights on the river are held by California, which has been reluctant to give ground—a polite way of saying that it has refused. Nevada negotiates from a position of relative weakness but exceptional efficiency because, of all places, Las Vegas recycles about 99% of its indoor water. The fact that a casino town is more orderly than the Imperial Valley’s alfalfa fields is an odd irony.
The southern front is another. Over the past year, the 1944 treaty with Mexico has become a source of pressure on its own. For the first time in more than 50 years, Washington refused to provide water to Tijuana earlier in 2025 in an effort to make Mexico pay back its own water debt to Texas farmers.
In response, Mexico sent 75 million cubic meters, which may seem like a lot, but it actually leaves them with about 1.5 billion in arrears. Speaking with people on both sides of the border gives the impression that nobody truly thinks the previous agreements are still in place.
Beneath all of this, there are subtly huge financial stakes. Last year, one sugar mill in southern Texas closed due to a lack of irrigation. Sonoran avocado growers use 91 liters of water per tree every day. The fact that alfalfa, the thirstiest crop on the continent, is transported from the Arizona desert to dairy farms in China and Saudi Arabia sounds made up when you say it aloud. Investors appear to think that whoever can afford to leave the most land fallow will eventually control the majority of the basin’s agricultural land. That might already be taking place.
In the meantime, Texas is throwing money at the issue, which is what Texas does. The legislature approved HB4, which will provide $53 billion over 40 years for conservation and new infrastructure. Bill Hoffman, who has worked in the state’s industrial water conservation sector for decades, notes that reverse-osmosis and reuse systems have already significantly reduced consumption for businesses like American Airlines and Freescale. In pockets, it’s working. However, 57% of the state’s water is still used for agriculture, and a 2012 University of Texas study quietly concluded that there are only a few decades left for farming as Texans know it.
As this develops, it’s easy to envision a tidy conclusion—some grand renegotiation, a Colorado Compact 2.0 hammered out in a Denver hotel ballroom. That’s probably not how it will go. The river will continue to get smaller. The number of lawsuits will increase. States will file lawsuits against one another, Washington, and then one another once more. The quote was accurate, according to Mark Twain or whoever said it. Whiskey should be consumed. More and more, water is a source of conflict. And by all reasonable standards, the battle has only just begun.
