On a cold fall day, Eric Kuhn walked alongside a gravel path above the Colorado River in Glenwood Springs, Colorado. The previous head of the Colorado River District, a water company primarily based on the state’s Western Slope, paused the place one among its tributaries, the Roaring Fork, spilled into the river, making a two-tone stream of beige and darkish brown on the confluence.
“A few third of the water that originates within the Colorado River might be accounted for proper at this spot,” Kuhn stated. The river is fed by melting snow which gathers every winter on the excessive mountain peaks of the southern Rocky Mountains.
“After I consider rivers, I consider, the place’s the water coming from and the place’s it going?” Kuhn stated. “And what’s occurred to this river during the last 100 years?”
In 2021 Kuhn co-authored “Science Be Dammed” together with his colleague John Fleck, a water coverage professor on the College of New Mexico. The guide is an in depth examination of how the river’s foundational settlement—the Colorado River Compact —got here collectively a century in the past.
The authorized doc turns 100 years previous this November. The settlement amongst seven western states to handle the river’s waters was groundbreaking for its time. However the anniversary of its Nov. 24 1922 signing comes because the river is dealing with arguably its most-pressing disaster. Water provides are shrinking on account of local weather change-induced warming. Calls for for water have but to shrink to match the drier circumstances. The river’s largest reservoirs are declining to document lows, and forecast to drop additional.
And that truth is prompting these grappling with the shrinking river to ask: What profit is the Colorado River Compact nonetheless giving the area’s water customers?
By the flip of the twentieth century, European settlers had been transferring into among the most arid reaches of the nation, spurred on by federal incentives for land. The southwest was quickly growing, however one factor was lacking—a secure water provide. The river’s flows had been excessive, transitioning rapidly from flood to drought.
When the floods got here to the agricultural communities of southern California, Kuhn stated the brand new residents started to consider the river as a menace, “and it created a political motion to regulate the river, this wild, raging river.”
That political local weather ultimately spurred leaders from the fledgling Western states of Colorado, Wyoming, New Mexico, Utah, Arizona, Nevada and California to view the river as an issue to resolve.
“We wanted to regulate nature. We wanted to determine a strategy to make this river from a menace to a pure useful resource to one thing that people might use and depend on.”
Anxieties about California’s inhabitants progress from these within the river’s higher reaches additionally contributed to the political local weather wanted for a Colorado River settlement to coalesce. If left unchecked, their pondering went, California might find yourself controlling your entire river, leaving each different state to scramble for what was left.
That mindset—of needing to regulate nature—and that jumble of anxieties introduced leaders from these states and the federal authorities to Santa Fe in 1922 to hammer out the settlement. It divided up the river’s water between an Higher and Decrease Basin, and promised every basin a hard and fast quantity to make use of. Every was allotted 7.5 million acre-feet per yr. The Compact did not put aside any water for the nation of Mexico, nor to the area’s Native American tribes. Kuhn says the negotiators selected political expediency over science.
“If everybody agrees that there’s sufficient water to satisfy all our wants, dividing it up goes to be very straightforward,” he stated. “If there’s not sufficient water, then it’s going to create problems.”
An rigid doc
The river’s hole between provide and demand was baked in from the beginning, stated Kathy Jacobs, a water coverage professor on the College of Arizona. Because the Colorado River Compact was signed, a posh authorized scaffolding of agreements, courtroom decrees and legal guidelines has been constructed on high of it. Nevertheless it stays the muse of the river’s administration.
“We’re 100 years later, and clearly our priorities are completely different than the priorities of the individuals who existed at the moment,” Jacobs stated.
The precedence then was irrigation water for the southwest’s small farms and the electrical energy large dams offered, she stated. The individuals negotiating the compact—all white males, largely engineers, legal professionals and politicians—weren’t considering what a future Phoenix metro space may want or how their choices would have an effect on the Grand Canyon’s ecosystems.
The compact put a hard and fast quantity of water on paper, and did not account for its variability, Jacobs stated. Because the local weather warms, the compact provides a false sense that the area will return to some form of regular.

“I don’t suppose that it’s notably versatile and we’re in a scenario the place flexibility will in all probability be key,” Jacobs stated.
As a result of extra water exists on paper than within the river itself, its largest reservoirs—Lakes Mead and Powell—proceed to say no to document lows. The present circumstances have made 2022 a somber yr for Colorado River Compact anniversary commemorations. This summer season federal officers referred to as on state leaders to comply with an unprecedented stage of conservation to carry the system into steadiness. These talks stalled, and tensions among the many states grew because the summer season progressed. Higher Basin leaders solid the blame downstream, whereas California’s use got here underneath a brand new stage of scrutiny from customers throughout the watershed. The acrimony among the many states, and the failure to coalesce across the wanted conservation measures, triggered federal officers to step in and start providing emergency direct funds to farmers to curb their use.
Heather Tanana, a College of Utah legislation professor and citizen of the Navajo Nation, stated the compact additionally represents how Indigenous individuals and their pursuits have been excluded from river administration over time. A few of Tanana’s work receives funding from the Walton Household Basis, which additionally helps KUNC’s Colorado River protection.
“Water for a lot of tribes, it’s not a commodity. It’s one thing sacred. It’s one thing that’s integral to not simply human life, however the broader group and environmental well-being,” she stated.
Collectively tribes maintain rights to greater than 20 p.c of the river’s water. However solely not too long ago have the states and the federal authorities taken severely requires a tribal seat on the negotiating desk.
“That’s been a shift within the final 5 years of recognizing tribal pursuits, their authorized rights, and past that, that tribes might be part of downside fixing,” she stated.
It’s unclear if the river’s present authorized construction can absolutely have in mind tribal views, Tanana stated. Similar for different voices unnoticed of early conversations on river administration, like these from environmental and recreation teams. Which is why, Tanana stated, she doesn’t scoff at individuals who argue for throwing out the compact utterly.
“Realistically, can we throw out the previous 100 years of the legislation of the river and the compact and begin from scratch? In all probability not,” she stated. “However in fascinated by throwing out the river then it prompts you to undergo an evaluation of, ‘Properly, what’s working? What’s not working?’”
Because the hole between provide and demand grows, and the unprecedented nature of the present disaster turns into extra clear, Tanana stated water leaders within the area can start to absorb extra progressive concepts to resolve it.
“I’m cautiously optimistic that we’re getting there, however I do suppose we should be very artistic in how we predict and never maintain on to one thing merely as a result of it was agreed upon 100 years in the past,” Tanana stated.
So with all of its fraught historical past and shaky scientific grounding, why would anybody wish to preserve utilizing the Colorado River Compact?
Kevin Wheeler, a river administration fellow on the College of Oxford within the U.Okay., stated extra water leaders are selecting to easily ignore among the compact’s finer particulars. Renegotiating the compact is a non-starter for a lot of state leaders. Newer agreements present some willingness to chop again on total water use voluntarily, with out tinkering with the compact itself.
“Though no particular person state desires to take the hit, all of them acknowledge the necessity to take the hit collectively,” he stated. “Definitely the numbers which were etched into stone within the compact could should be floor out slightly bit and rethought.”
Tearing it up can be virtually unattainable, he stated. The area has grown too depending on it. He says one of the best ways ahead is to stay with much less water. Individuals will find yourself having no selection however to disregard the compact’s fanciful guarantees.
“What’s usually been stated is we’re not going to do away with it,” he stated. “However we could should bend the hell out of it to make it work.”
