Tracking the coronavirus pandemic could soon be a bit easier because of one simple fact: everyone poops.

Around the world , wastewater plants have become unlikely sentinels in the fight against the virus, allowing scientists to track the disease's spread at the community level. The practice of testing sewage samples is spreading across Western U.S. states as well, with programs currently running in Utah, Nevada, Arizona and California.

Charismatic is hardly the best word to describe the humpback chub, a fish with a frowny eel face jammed onto a sportfish body in a way that suggests evolution has a sense of humor. Nor did tastiness build a fan base for this "trash fish" across its natural habitat throughout the Colorado River Basin. But, in 1973, the humpback chub became famous by winning federal protection under the Endangered Species Act.

The water has made development possible and is used for farms, homes and businesses. Meanwhile, recreation has risen to over 4 million annual visitors in Glen Canyon National Recreation Area, with tourists bringing in over $420 million to local communities.

A tight-lipped Western Colorado irrigation association is remaining neutral on the growing presence of private investors in their sizable pool of senior water rights.

Twenty-two miles outside of the nearest town (Wells, pop. 1,246), graffiti on a crumbling hotel wall reads: "Home on the Strange." Down a dirt road, there's an abandoned car. An arch stands at the entrance of a dilapidated school. It's what is left of a town that lost most of its water rights.

Around the turn of the last century, New York investors established Metropolis, Nevada as a farming community. By 1912, they had constructed a dam. They built a hotel, a school and an events center. The Southern Pacific Railroad constructed an office and built a line to the town.

Then the water ran dry.

Central Arizona has been booming -- more people, more houses, more need for water. There's also a long-term drought, and less water to buy from the Central Arizona Project canal system . It's leading Phoenix exurbs to cast about, looking for new buckets.

Other regions of the state say: don't come here.

For five years, Zay Lopez tended vegetables, hayfields and cornfields, chickens, and a small flock of sheep here on the western edge of Colorado's Grand Valley - farming made possible by water from the Colorado River.

Lopez has a passion for agriculture, and for a while, he carved out a niche with his business, The Produce Peddler, trucking veggies seven hours away to a farmers market in Pinedale, Wyoming.

Lopez also moonlights as a Realtor, with his finger on the pulse of the local real estate market. A few years ago, he noticed a strange new phenomenon. Much of the irrigated agricultural land sold in the valley - such as parcels just down the road from his farm - wasn't being bought by another farmer. Instead, his new neighbor was Water Asset Management, a New York City-based hedge fund with deep pockets.

A wastewater facility on Colorado's Western Slope is resuming operations more than a year after it was shut down for causing a sizable earthquake in 2019.

Finding Columbia spotted frogs in Utah's mountains is not easy. But it's possible, with a guide like Paula Trater. She leads a visitor down a dirt path, then through mucky wetlands filled with cattails and a riot of birdsong.

Colorado has its first two "presumptive positive" cases of COVID-19, the illness caused by the latest coronavirus. State health officials on Thursday confirmed an out-of-state visitor to Summit County has tested positive.

Coal-fired power plants are closing, or being given firm deadlines for closure, across the country. In the Western states that make up the overallocated and drought-plagued Colorado River, these facilities use a significant amount of the region's scarce water supplies.

With closure dates looming, communities are starting the contentious debate about how this newly freed up water should be put to use.

A warming climate is already causing river flows in the Southwest’s largest watershed to decline, according to a new study from federal scientists. And it finds that as warming continues it’s likely to get worse. 

Every time thick, dark rain clouds move over the deserts that surround Las Vegas, there's an anticipatory buzz. Flora and fauna alike begin preparing for the rare event, lying in wait for the first few drops.

Todd Esque is usually waiting for them too from his office in Henderson, Nevada. He knows how much desert life depends on their arrival. So when they do come, he's smiling.

With short-term drought plans finished, water managers from across the Southwest recently gathered in Las Vegas to figure out what's next.

The Colorado River Water Users Association annual conference brings together nearly every municipal water agency, irrigation district, Native American tribe and environmental group that relies on the Colorado River.

The federal government is now taking comments on alternatives to a project in western Colorado notorious for causing earthquakes. 

The Bureau of Reclamation is looking for replacements for the Paradox Valley Unit, located in a remote part of western Colorado’s Montrose County. The agency released a draft environmental impact statement for those replacements Friday. 

The West’s water security is wrapped up in snow. When it melts, it becomes drinking and irrigation water for millions throughout the region. A high snowpack lets farmers, skiers and water managers breathe a sigh of relief, while a low one can spell long-term trouble.

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.”
