Your Colorado River water leaders have buried their heads in the sand and created a crisis for the entire Colorado River Basin.
For decades, the seven states of the Colorado River Basin have been taking more water from the river and its tributaries than actually exists. Climate change has shortened our winters and diminished the size of our snowpack, so the Colorado River’s flows have declined 20% over the last 25 years compared to the 20th century.
These are the reasons America’s two largest reservoirs – Lake Mead and Lake Powell – have been shrinking for decades. Powell is now at 24% of its capacity, and Mead is at 30%. Earlier this year, the Bureau of Reclamation forecast that Lake Powell’s water levels would drop so low that hydropower would have to be shut off inside Glen Canyon Dam in 2026. Water managers have delayed this inevitable disaster by taking water out of Upper Basin reservoirs like Flaming Gorge to try and prop up Lake Powell’s water levels.
This has delayed the impacts of this gigantic crisis, but it is still coming because Glen Canyon Dam’s infrastructure was not designed with climate change in mind. The dam’s hydropower tubes are the only way to deliver enough water to satisfy water delivery agreements in the 1922 and 1948 Water Compacts, so turning off the hydro means that Upper Basin states won’t be able to fulfill their mandatory water delivery obligations to the 25 million people downstream.
If water leaders had acted to solve this plumbing problem, we could be working towards a solution now. Instead, we continue to waste precious time because water leaders refuse to acknowledge the realities of climate change. We’re now facing the penalty for their climate change denial.
Glen Canyon Dam has become a liability to sound water management in the Colorado River Basin. Now is the time to retrofit the dam instead of just crossing our fingers and hoping for a big winter.
