The Colorado River Compact at 100

On November 24, 1922, representatives of the seven Colorado River basin states—Arizona, California, Colorado, New Mexico, Nevada, Utah, and Wyoming—gathered in Santa Fe, N.M., to signal the Colorado River Compact, cementing into regulation a regime for dividing the river’s water. With out exception, these males have been newcomers to a area inhabited since time immemorial by Native American Tribes. Two of them represented states only a decade outdated, none represented states greater than 75-years-old, and their goal was to allow colonial settlers to ascertain a foothold by way of irrigation-driven financial growth.

On the centennial anniversary of the creation of that consequential doc, as Colorado River reservoir ranges have plummeted to historic lows, Native American Tribes stay disadvantaged of entry to water rightfully theirs, and we see degradation of freshwater-dependent ecosystems all through the basin, it appears value asking whether or not the Compact serves us nicely.

At the moment, elected leaders of those seven states nonetheless regard the Compact as an important, foundational doc, and regardless of its flaws, it’s nonetheless thought of the bedrock of “the Legislation of the River” which additionally contains Worldwide Treaties with Mexico, federal and state legal guidelines, and rules.

They level to the first intent of the Compact: “to supply for the equitable division and apportionment of the usage of the waters of the Colorado River System.” By 1922, “prior appropriation” was established because the regulation of the land inside every of the Colorado River Basin States, which means those that first took water from the river would have senior water rights and water developments that adopted could be subordinated. If there wasn’t sufficient water to satisfy all of the rights, the senior proper would get water and the junior would get none. The negotiators from the “Higher Basin” states of Colorado, New Mexico, Utah, and Wyoming shared a priority that water customers in “Decrease Basin” states California and Arizona would put Colorado River water to make use of earlier than they might (Nevada can also be within the Decrease Basin, however so few individuals lived there in 1922 they weren’t seen as a menace). The proof: in 1901, irrigators started diverting huge portions of Colorado River water onto farms within the Imperial Valley in California and the Yuma Valley in Arizona. The Higher Basin states weren’t placing wherever close to these volumes of water to make use of and sought the precise to develop at their very own tempo sooner or later, with out having to fret that the Decrease Basin states would declare your entire Colorado River provide in senior rights. The answer within the Compact was to divide the Colorado’s water equally between the Higher and Decrease Basins, whatever the price at which water was developed.

It’s this “equitable division” of the Colorado’s water that many proceed to view as important. A century later, “equitable apportionment” between the basins nonetheless sounds affordable, but when the seven Colorado River Basin States wish to preserve the Colorado River Compact in place, they’ve quite a lot of work to do, as a result of it’s indeniable that in 2022 Colorado River administration is damaged. Essentially the most seen drawback is clear in reservoirs at historic lows and terribly excessive threat of crisis-level water shortages for the 40 million individuals, and 5.5 million acres of farmland that depend on the river—however that’s hardly the extent of it. The Compact neglected—or intentionally averted—values we should always uphold right now as necessary, together with fairness for tribal communities and sustainable ecosystem administration. At the moment’s states could view the Compact as important to preserving the peace, but when they need the Compact to outlive, they are going to want shortly to adapt the Compact to right now’s requirements by adopting guidelines and agreements that remedy a number of issues:

The Compact can not not obtain what the states outlined as equitable apportionment with right now’s river flows. Prolonged drought exacerbated by local weather change has led to a median Colorado River yield of 12.4 million acre-feet of water in latest many years, whereas the Compact is premised on a stream of a minimum of 16 million acre-feet. The Compact defines the right way to accomplish equitable distribution of water between the Higher and Decrease Basins by prohibiting the Higher Basin from depleting flows to the Decrease Basin beneath a median of 75 million acre-feet in any 10-year interval, however there’s not sufficient water for the Higher Basin to fulfill that obligation and develop one other 7.5 million acre-feet of water for annual use. Furthermore, as local weather change will increase aridification within the basin and the common water yield decreases additional, the Higher Basin’s entry to Colorado River will proceed to shrink. In different phrases, drought and local weather change have thrown a wrench into the Compact’s framework for managing the basin. Going ahead, the states want both to discover a option to fold the realities of local weather change right into a workable administration framework or threat the ramifications of an unsure future for communities, economies, and ecosystems all through.

The states negotiated the Compact domestically, and with out Mexico on the desk they acknowledged each the Higher and Decrease Basins would have tasks to supply water in occasion of a subsequent treaty; years later the 1944 Treaty was adopted, however there’s no readability on which basin is liable for offering the water. The truth that the states in 1922 noticed match to allocate the Colorado’s water with out together with Mexico speaks volumes about how their negotiators noticed their neighbors to the south. Regardless, the 1944 Treaty assured to Mexico 1.5 million acre-feet of water yearly besides within the occasion of extraordinary drought. Whereas the Compact holds that the 2 basins ought to share the duty to ship that water when there’s not sufficient over and above the U.S. allocations, there isn’t any settlement on what which means legally. For instance, does the Higher Basin want to make sure flows reaching the Decrease Basin embrace an additional 0.75 million-acre-feet yearly? What would that do to the Higher Basin’s probabilities of having the ability to develop its half of the Colorado’s water?

The Compact intentionally averted incorporating allocations for Native American Tribes, who stay largely lower out of choices about Colorado River administration and in too many circumstances haven’t but gained entry to their water. This appears significantly egregious on condition that the Supreme Court docket dominated on the idea for figuring out Tribal water rights in 1908. Winters v. United States holds that Tribes might have an implied proper to water based mostly on the phrases of their reservation, with seniority based mostly on the Treaty date establishing the reservation. At the moment, the 30 federally acknowledged Tribes within the Colorado River Basin have secured rights to as a lot as 20% of all Colorado River water within the Basin. Nonetheless, greater than a 3rd of the Basin’s Tribes have but to settle their Colorado River water rights.  Furthermore, even these with settled rights nonetheless lack adequate infrastructure to entry their water rights in a significant method, and all of the Tribes nonetheless lack a proper seat on the desk the place Colorado River administration choices are made.

The Compact didn’t acknowledge and doesn’t acknowledge nature’s water wants. Nowhere within the Compact is there language recognizing the worth of water to pure techniques in addition to the legions of birds, fish, and different wildlife that rely upon freshwater-dependent ecosystems. That failure underpins a century of devastating losses. A number of packages have been established below the 1973 Endangered Species Act, however too most of the Colorado Basin’s rivers stay unhealthy and in danger. Dozens of species of Colorado River fish and wildlife are listed as threatened or endangered, and the Colorado River Delta, a lush ecosystem of 1.5 million acres, was allowed to dry up and disappear in the course of the 20^th century. The U.S. Bureau of Reclamation has raised the prospect that throughout the subsequent yr or two, it could grow to be inconceivable to go water by way of the Glen Canyon Dam, successfully eliminating the Colorado River floor flows from the Grand Canyon. The Compact’s promise of water for growth is determined by wholesome rivers, and the area’s economies are depending on the sustainability of pure techniques. But, in its utility, the Compact has allowed hurt to the Colorado River and its tributaries, each dwelling factor that is determined by them, and all of us who worth it for leisure, cultural, and religious causes.

The looming water disaster within the Colorado River Basin requires pressing administration changes and variations to fulfill the challenges of right now. Because the Colorado River Basin States contemplate how they are going to share the diminishing water provide, they need to on the identical time be rectifying the Compact’s errors, oversights, and omissions. Audubon will proceed to advocate for administration that gives improved reliability of water for the 40 million individuals who rely upon it, elevated advantages for Native American Tribes from their water rights, and sustainable habitat for the tons of of species of birds and wildlife that decision it house. The Colorado River Basin States must show this may be accomplished by way of adaptation throughout the framework of the Colorado River Compact and the Legislation of the River. In the event that they as an alternative use the Compact and different venerable legal guidelines to argue these outcomes usually are not potential, they are going to be proving the authorized framework will want greater than adjustment—it is going to want full reform.
