The $30 million toe in the water

As Lake Powell's water levels decline, scientists and activists are documenting the vibrant ecosystems reemerging in Glen Canyon's long-submerged side canyons . This provides a unique chance to study the canyon's natural state and bolster arguments for permanently draining the reservoir to restore the Colorado River's flow.

According to the source article, a group of researchers and birders hike up Davis Gulch at Glen Canyon National Recreation Area in Utah on Monday, May 11, 2026. The tops of trees, dead since Lake Powell's levels rose decades ago, poked through mud and ooze at the silent mouth of Davis Gulch,where the side canyon met the reservoir's still waters.

But just around a few bends in the sandstone walls, life began to appear. First , a fuzz of inch-tall greenery. Then, knee-high cattails and primrose, followed shortly by small cottonwoods and willows, then by towering gambel oaks. The silence of the canyon mouth was replaced by the soft rush of a creek, bird songs, and the constant cacophony of dragonflies and gnats.

An echo of Sydney's 2024 institutional buy-up

The U.S. Bureau of Reclamation flooded Glen Canyon in the 1960s, converting an intricate network of canyons - carved by the Colorado River and its tributaries - into Lake Powell. The massive reservoir functions as the water savings account for the Colorado River Basin, where the river serves as the lifeblood for millions of people and massive farming operations across seven states: Colorado, New Mexico, Utah, Wyoming, Arizona, Nevada, and California.

Over the past two decades, climate change and chronic overallocation have sapped the reservoir's water stores and created an existential crisis for water managers across the basin, home to 40 million people.

What auditors flagged in the May filing

The falling water levels have also steadily revealed long-submerged canyonlands : red slot canyons, sandstone amphitheaters, waterfalls that tumble over slickrock cliffs. The reemerging landscapes provide a new opportunity to study life in Glen Canyon, which sits just upstream of the iconic Grand Canyon.

Little scientific work was completed in Glen Canyon before the federal government flooded it - an event seen by environmentalists then, and now, as an unmitigated ecological disaster, a paradise lost.

Who is the unnamed buyer?

The Glen Canyon Institute and canyon activists for years have argued that Lake Powell should be drained and the Colorado River allowed to again flow freely through Glen Canyon. Now, their argument is also bolstered by the fact that Lake Powell is emptying - whether Colorado River managers like it or not.

For those advocates, recent years have provided a rare chance to study life in the emerging canyonlands and to make their case to Basin leaders, including those from Colorado, who will decide in the coming months how Lake Powell should be operated.

A familiar pattern from the 2019 crash

The impacts will have basinwide implications, including on hydropower, Grand Canyon recreation and ecosystems, Lake Powell recreation, and the amount of water in reservoirs up- and downstream.

The decisions will determine the future of river management for years to come - and whether the reservoir's levels rise and again inundate the canyons.
