Century-Old Words Spark Intense Dispute Over Colorado River's Fate as Western States Grapple with Water Crisis

In the ongoing struggle over the Colorado River's fate—an artery of life for 40 million people in the West—a small collection of words penned in 1922 has become the epicenter of a heated debate. As the states involved are locked in stalemate, unable to forge a unanimous plan, the meaning of a singular phrase in the Colorado River Compact looms large over current negotiations, as reported by AZPM.

Patty Rettig, archivist at Colorado State University, has sifted through the historical documents in search of insights. She told AZPM the authors “I know they were thinking about the future.” With guidelines set to expire in 2026, and a climate crisis bearing down hard, the two basin coalitions have begun to dig in their heels securely, each proposing varying visions for managing the river's scarce waters.

The Upper Basin states have proposed a plan that could potentially allow them to let less water flow downstream under certain conditions, justifying their stance by the document's phrase will not cause. According to the original text of the compact, they argue that they aren't the cause for less water reaching the Lower Basin. This interpretation has generated significant friction with the Lower Basin states.

Eric Kuhn, former head of the Colorado River District, acknowledged in a statement obtained by AZPM that the idea to interpret the clause in this way may have germinated in the early 2000s as a response to the persisting water shortage spurred by climate change. Yet he expresses caution, viewing this reading as more tactical than definitive. The Lower Basin has reacted promptly, challenging the Upper Basin's perspective, highlighting that “Arguing legal interpretations until we’re all blue in the face doesn’t do anything to proactively respond to climate change,” as JB Hamby, California’s top water negotiator articulated.

The crux of the issue resides in those three disputed words from Article III, Section D of the century-old compact. Water law expert Robert Glennon, in an interview with AZPM, warns that taking this disagreement to the courts would be less than desirable, likening the compact’s brevity to an apartment lease, lacking in detailed legal definitions that could clarify its original intentions. Glennon suggests that it's the mutual understanding of the river's division at Lee's Ferry that resonates as the compact's clear mandate.

Water negotiators have signaled an intent to extend discussions beyond the anticipated November timeline, possibly stretching closer to the 2026 deadline, reports AZPM. The Bureau of Reclamation, holding proposals from both basins along with inputs from tribal nations and environmental organizations, urges the states to converge on a resolution to avoid disruption from potential administrative turnovers. Jim Lochhead, a key figure in promoting the contested interpretation, now echoes the consensus that avoiding legal complications in favor of cooperative agreement remains critical for the river—and the region’s—future.
