As climate change continues to sap the Colorado River’s water, some users face serious legal risks to their supplies, according to a new analysis by researchers in Colorado and New Mexico. 

Declining flows could force Southwest water managers to confront long-standing legal uncertainties, and threaten the water security of Upper Basin states of Colorado, Wyoming, Utah and New Mexico.

Earlier this year, Arizona -- one of seven southwestern states that rely on the Colorado River -- was in the midst of a heated discussion about water.

“It’s time to protect Lake Mead and Arizona,” the state’s Republican governor, Doug Ducey, said in his state of the state address in January 2019. He spoke to lawmakers in the midst of uncomfortable, emotional discussions at the statehouse in Phoenix about who gets access to water in the arid West, and who doesn’t.

Proposition DD has passed with 50.7% of the vote, according to unofficial vote totals from the Colorado Secretary of State's office. The Associated Press called the race Wednesday afternoon. Starting May 2020 the state will be regulating and taxing sports gambling in the state, with the vast majority of revenue set aside for projects and programs laid out in the Colorado Water Plan. 

Climate change has been called the new normal. But residents in some parts of the Southwest say after living through the last two years, there’s nothing normal about it. 

Communities in the Four Corners -- where the borders of Colorado, Utah, New Mexico and Arizona meet -- have been bouncing between desperately dry and record-breaking moisture since the winter of 2017, forcing people dependent on the reliability and predictability of water to adapt.

Music is blaring and grills are firing up at a parking lot awash in navy blue and orange outside Empower Field at Mile High Stadium in Denver.

Todd Endicott of Lafayette stands outside an ambulance turned Broncos fan-mobile. He outfitted this orange and blue rig for tailgates. It’s plastered in life-size stickers of players, and the football team’s logos, vintage and new. 

Steamboat Springs, like many of Colorado's high country resort communities, is grappling with how it wants to grow.

The city itself has more than doubled in population since 1990. Seasonal tourist booms formerly contained to summer and winter have bled over into spring and fall. With its increasingly sought after outdoor amenities, like hot springs, camping, hiking, mountain biking and skiing, the town swells with visitors most weekends out of the year.

Finding a river in the West that still behaves like a Western river -- one that rises and falls with the annual rush of melting snow -- is tough. 

Many of the region’s major streams are controlled by dams. Their flows come at the push of a button. Instead of experiencing dynamic flows, dammed rivers are evened out. Floods are mitigated and managed, seen as a natural disaster rather than an ecological necessity. 

One hundred and fifty years ago, a group of explorers led by Civil War veteran John Wesley Powell set out to document the canyons of the Green and Colorado Rivers. It was the first trip of its kind. To commemorate the journey, a group of scientists, artists and graduate students from the University of Wyoming called the Sesquicentennial Colorado River Exploring Expedition has been retracing his steps this summer. 

Wells built to bring underground water supplies to the surface are being dug deeper to tap into dwindling aquifers, according to a new study.  

The internet loves certain things: rooting for an underdog, poking at humorless institutions, and coming up with ridiculous names. 

A flap over the name of Grand Junction’s minor league baseball team has all those elements in spades, which probably explains how it took over the internet this week. 

One morning in mid-February, David Herz went to turn on the faucet in his farmhouse outside the small western Colorado town of Paonia, and nothing came out.

“I thought, ‘Oh, f---. We got a problem,’” Herz said.

The Colorado River is short on water. But you wouldn’t know it by looking at a slate of proposed water projects in the river’s Upper Basin states of Colorado, Utah and Wyoming.

The river and its tributaries provide water for 40 million people in the Southwest. For about the last 20 years, demand for water has outstripped the supply, causing its largest reservoirs to decline.

Snowpack in every part of Colorado’s high country is sporting layers of dust, according to a new statewide survey of the state’s winter accumulation.

“This is a low frequency dust season,” wrote Jeff Derry, head of the Colorado Dust on Snow Program, in a post about the survey results. “But may be a high consequence snowmelt season.”

CIÉNEGA DE SANTA CLARA, MEXICO — Juan Butrón-Méndez navigates a small metal motorboat through a maze of tall reeds here in the Mexican state of Sonora. It’s nearing sunset, and the sky is turning shades of light blue and purple.

The air smells of wet earth, an unfamiliar scent in the desert.

LAGUNA GRANDE, BAJA CALIFORNIA, MEXICO — It’s mid-morning in the Sonoran desert and already the temperature is rising.

Karen Schlatter suggests we find some shade, a relatively easy task at Laguna Grande, a restoration site along the Colorado River’s historic channel in Mexico. It’s managed by the Sonoran Institute, where Schlatter is associate director of the binational environmental group’s Colorado River Delta program.

SAN LUIS RIO COLORADO, MEXICO — From inside a small airplane, tracing the Colorado River along the Arizona-California border, it’s easy to see how it happened.

As the river bends and weaves through the American Southwest, its contents are slowly drained. Concrete canals send water to millions of people in Phoenix and Tucson, Los Angeles and San Diego. Farms, ribbons of green contrasted against the desert’s shades of brown, line the waterway.

High snowpack in the southern Rocky Mountains this winter will likely stave off a shortage declaration in the Colorado River watershed in 2020, relieving pressure on water managers attempting to navigate future scarcity.

New data from U.S. Bureau of Reclamation models show a lessened risk of a key Colorado River reservoir dropping far enough to trigger a first-ever shortage declaration. Snowpack in the Upper Colorado River Basin is at 138 percent of the long-term median, a level not seen in mid-March since 1997.

Water is again flowing through faucets in the Western Slope town of Paonia.

Town administrator Ken Knight told residents at a meeting Tuesday evening enough water is being treated and kept in storage to return service to the more than 1,500 people who rely on the town for drinking water. Some residents have been without drinkable tap water for nearly two weeks after officials discovered leaks in water pipes.

When Paonia resident Jon Howard went turn on the dishwasher last Friday morning, there was no water to clean the dishes.

Same thing when he went to the bathroom, wanted to take a shower or fill up a glass from the kitchen sink.

States that rely on the Colorado River for their water supplies are currently unable to finish a series of agreements that would keep its biggest reservoirs, Lake Mead and Lake Powell, from dropping to levels not seen since they were filled decades ago.

Five states — Colorado, Utah, New Mexico, Wyoming and Nevada — are done. The country of Mexico has also completed its portion. But California and Arizona failed to meet a Jan. 31 federal government deadline to wrap up negotiations and sign a final agreement.

Each winter, anxious water managers, farmers and city leaders in the American Southwest turn their eyes toward the snowy peaks of the southern Rocky Mountains.

The piling snow is a massive frozen reservoir, and its depth and weight can foreshadow the year ahead. Millions of dollars are spent divining what a heavy or light snowpack means for the region's reservoirs, for its booming cities, for its arid farmland.

Following one of the hottest and driest years on record, the Colorado River and its tributaries throughout the western U.S. are likely headed for another year of low water.

That’s according to an analysis by the Western Water Assessment at the University of Colorado Boulder. Researcher Jeff Lukas, who authored the briefing, says water managers throughout the Colorado River watershed should brace themselves for diminished streams and the decreasing likelihood of filling the reservoirs left depleted at the end of 2018.

The briefing relies on data from the National Oceanic and Atmospheric Administration, the U.S. Geological Survey and the Natural Resources Conservation Service among others.

On stage in a conference room at Las Vegas's Caesars Palace, Keith Moses said coming to terms with the limits of the Colorado River is like losing a loved one.

"It reminds me of the seven stages of grief," Moses said. "Because I think we've been in denial for a long time."

Moses is vice chairman of the Colorado River Indian Tribes, a group of four tribes near Parker, Arizona. He was speaking at the annual Colorado River Water Users Association meeting.

LAS VEGAS -- Water leaders throughout the West now have a hard deadline to finish deals that would keep the Colorado River’s biggest reservoirs from dropping to deadpool levels.

The nation’s top water official is giving leaders of the seven states that rely on the Colorado River until January 31, 2019 to finalize a Drought Contingency Plan. The combination of multi-state agreements would change how reservoirs are operated and force earlier water cutbacks within the river’s lower basin states of Arizona, California and Nevada as reservoirs drop.

Colorado River water managers have plenty to argue about. But there’s one thing on which nearly everyone who relies on the southwestern river can agree. The foundational document that divvies up the water -- the Colorado River Compact -- has some big flaws.

Discussion on how to fix the compact’s problems is where that consensus breaks down, often with the invocation of one word: renegotiation.

The temperature is hovering right around 90 degrees the day Dale Ryden and I float down the Colorado River near Grand Junction, Colorado. The water looks so inviting, a cool reprieve from the heat, but if either of us jumped in we’d be electrocuted.

“It can actually probably be lethal to people if you get in there,” Ryden, a fish biologist with the U.S. Fish and Wildlife Service, says.

Water managers along the Colorado River are trying to figure out how to live with less.

Climate change is growing the gap between the river’s supply, and the demands in the communities that rely on it, including seven western U.S. states and Mexico. The federal government recently released proposals called Drought Contingency Plans designed to keep the Colorado River’s biggest reservoirs from falling to levels where water is unable to be sent through the dams that hold up Lakes Powell and Mead.

Key reservoirs along the Colorado River are collectively at their lowest point at the start of a new water year since the last one filled nearly 40 years ago.
