Momentum is building for a unique interstate deal that aims to transform wastewater from Southern California homes and business into relief for the stressed Colorado River. The collaborative effort to add resiliency to a river suffering from overuse, drought and climate change is being shaped across state lines by some of the West’s largest water agencies.
The U.S. Bureau of Reclamation announced two measures today to boost water levels in Lake Powell, keeping them high enough to continue generating hydropower at the Glen Canyon Dam. Both moves are being framed as painful but necessary band-aids, cutting into reserves elsewhere in the region to stave off the worst effects of a decades-long drought that has sapped the nation’s second-largest reservoir.
One measure will send water from upstream to help refill Lake Powell. About 500,000 acre-feet of water will be released from Flaming Gorge Reservoir, which straddles the border between Wyoming and Utah.
With long-term severe drought continuing to take a toll on the Colorado River, the federal government is expected to announce on Monday that it will retain some water in one of the river’s major reservoirs to temporarily stave off what it called increased uncertainty in water and electricity supplies.
The anticipated decision to keep more water in Lake Powell on the Arizona-Utah border, rather than releasing it downstream to the other major reservoir, Lake Mead near Las Vegas, comes as both are at record-low levels after 20 years of drought.
A massive drought-starved reservoir on the Colorado River has become so depleted that Las Vegas now is pumping water from deeper within Lake Mead where other states downstream don’t have access.
The Southern Nevada Water Authority announced this week that its Low Lake Level Pumping Station is operational, and released photos of the uppermost intake visible at 1,050 feet (320 meters) above sea level at the lake behind Hoover Dam.
“While this emphasizes the seriousness of the drought conditions, we have been preparing for this for more than a decade,” said Bronson Mack, water authority spokesman. The low-level intake allows Las Vegas “to maintain access to its primary water supply in Lake Mead, even if water levels continue to decline due to ongoing drought and climate change conditions,” he said.
The move to begin using what had been seen as an in-case-we-need-it hedge against taps running dry comes as water managers in several states that rely on the Colorado River take new steps to conserve water amid what has become perpetual drought.

Somewhere between Bullfrog, Utah, and the Hole in the Rock trailhead, I’m following the distant rumbling of a waterfall, echoing between 500-foot walls of Navajo Sandstone. Not far from here is Cathedral in the Desert — a famed grotto in the heart of Glen Canyon. It gives me chills, knowing that this sound hasn’t been heard since 1968. After rounding one last corner of the canyon, there it is: a 60-foot cascade bellowing into a clear pool. Water in the desert is a magical thing. It’s also a complicated thing.
Because of the megadrought that’s gripping the southwestern United States, the federal government is cutting back how much water it delivers to California, Arizona and Nevada by a lot, about as much as Las Vegas uses in a year. It’s something water managers never thought they’d have to do. Alex Hager reports on the Colorado River from member station KUNC in Greeley, Colo., and joins us now to explain what’s going on. So decades ago, the U.S. built huge dams on the Colorado River specifically to store water as insurance against droughts. Why isn’t that system working now?
In a letter sent Friday, the seven states that use the Colorado River agreed with the U.S. Department of Interior and recommended that federal water managers take an emergency action aimed at stabilizing a dwindling Lake Powell, one of the main storage reservoirs on the river.
Earlier this month, federal water managers warned the states, including Nevada, that they were considering an emergency action to hold water back in Lake Powell, an attempt to stabilize the reservoir at serious risk of losing the ability to generate hydropower and deliver water to Page, Arizona, a city with roughly 7,500 residents, and the LeChee Chapter of the Navajo Nation.
Flaming Gorge reservoir in Wyoming will release 500,000 acre-feet of water under a new Drought Operations Plan to help prop up dangerously low water levels at Lake Powell.
The plan, approved Thursday by the Upper Colorado River Commission, does not call for any water to be released from Blue Mesa west of Gunnison, but also does not rule out the possibility of that being an option in the future.
The Colorado River’s 1,450-mile run begins amid the snowy pinnacles of the Rocky Mountains and ends in the subtropical waters of the Gulf of California. Over the millions of years the river has been running this course, it has gradually carved through the Southwest’s crimson limestone and shale to create a succession of unimaginably vast canyons: Ruby, Cataract, Marble, and Grand. The writer Marc Reisner described the Colorado as the “American Nile.” The Hualapai call it Hakataya, “the backbone.”
