DetailsVail Daily writer Gary Wockner argues that damming and diverting the Colorado River creates a feedback cycle of greenhouse gas emissions, accelerating the drying of the Southwest and threatening future water supplies.

Aspen —A $14 million project. Twelve units. That’s the kind of granular, hyper-local detail we usually dig for when tracking housing starts in Grand County. But Gary Wockner isn’t talking about a new condo complex in Vail or a subdivision in Carbondale. He’s talking about the entire Colorado River system, and he’s arguing we’re stuck in a “climate doom loop.”
Wockner, writing in the Vail Daily, lays out a case that’s equal parts scientific report and bureaucratic critique. The core problem? We’re trying to fix a drying waterway with the same tools that helped dry it out in the first place.
Let’s look at the data he’s pulling from. A new report from the University of Colorado Boulder predicts flows in the system could drop 30% more by 2050 due to climate change. That’s not a projection for next year. That’s a half-century horizon. And here’s the kicker: preclimate flow levels aren’t coming back. We aren’t returning to normal. We’re settling into a new, drier baseline.
Wockner calls this the “climate doom loop.” It’s a feedback cycle where damming and diverting water causes greenhouse gas (GHG) emissions, which dry out the Southwest, which forces decision-makers to build more dams or pump more water, which creates more emissions. It’s the “law of unintended consequences” mixed with the “sunk-cost fallacy.” We’ve already spent the money on Glen Canyon Dam and Powell Reservoir, so we keep trying to save them, even if the science says we’re making things worse.
The evidence isn’t just theoretical. Wockner cites a study by “Tell The Dam Truth” showing that the massive damming of the main stem is itself a source of GHG emissions. It’s not just the turbines. It’s the dry-up of 2 million acres of wetlands in the Colorado River Delta in Mexico. That loss of wetland area is the biggest source of GHG emissions in the whole system.
Another study in Nature Communications found that in drier climates, human interventions like pumping water for farms and clearing land actually intensify dry conditions. We’re not just capturing water; we’re accelerating the drying.
And then there’s the reservoirs themselves. A study in Nature Water indicates that as the climate warms, reservoirs become warmer and more polluted, emitting even more GHGs. The estimate? Reservoir emissions at the latitude of Glen Canyon Dam could increase between 20% to 80% by the end of this century.
Wockner argues that the U.S. Bureau of Reclamation, which manages the waterway, needs to pull back from its “high-stakes gambit” of trying to “save” Glen Canyon Dam and its hydroelectricity. On paper, it looks like a victory for power generation. In practice, it might just be accelerating the very climate change that threatens the river’s flow.
For locals, this isn’t just academic. It means the water we rely on for irrigation, drinking, and recreation is facing a structural decline that engineering fixes alone can’t reverse. The Bureau’s current strategy is betting on more dams and more pumping. Wockner says the science suggests that’s a losing bet.
The bottom line? We’re not just managing a river anymore. We’re managing a feedback loop that’s getting harder to control. If the 30% drop in flows by 2050 holds true, the cost of maintaining the status quo — in terms of energy, water rights, and ecological health — is going to be much higher than we’ve been willing to pay.
