Returning Rapids ProjectSee the changes in Cataract and Glen Canyon

Over the last several years, our partners in Moab have been surveying and researching the huge changes happening along the Colorado River through Cataract, Narrow, and now Glen Canyons. Please click below to visit their site and explore the work they have done to understand how the river is evolving as the reservoir recedes.

A plumbing issue at this Lake Powell dam could cause big trouble for Western water

It’s the latest twist in the saga of Glen Canyon Dam, which has been at the center of recent concern about the shrinking Colorado River, even before news of the damaged pipes came to light. Water experts fear Lake Powell could drop so low that water would be unable to pass through hydropower turbines that generate electricity for about 5 million people across seven states. If it falls even lower, water would be unable to pass through the dam at all, keeping it out of the Grand Canyon just downstream of Lake Powell.

Humans Killed Cataract Canyon. It Brought Itself Back to Life

Sixty years ago, this stretch of river was considered as ferocious — and nearly as beautiful — as the Grand Canyon. Then, in 1963, the Glen Canyon Dam was built to store water for human use, which backed up the Colorado River behind it to create Lake Powell. The rising waters snaked upstream, inundating the main river and dozens of its side canyons. Here, at its farthest reaches in Cataract Canyon, the reservoir flooded rapids and then buried the riverbed, including the boulders that made up those rapids, in thick layers of sediment — a mud plug that built up to be so enormous that it flattened out the steep gradient of the riverbed that had made those rapids so fierce.

Uncovering the Layered History of Glen Canyon Dam: A Tale of Dispossession and Indigenous Voices

She argues that the dam is not merely a utilitarian structure but a physical manifestation of Indigenous dispossession. This perspective challenges traditional narratives surrounding the dam, offering a fresh and nuanced understanding of its origins and impact.
