The 6 States Facing The Most Serious Groundwater Crises

A heating planet and expanding commercial agriculture are putting increasing pressure on America’s vital aquifers — underground reservoirs that supply water to an estimated 145 million Americans, as well as supporting much of the nation’s food supply.

How Last Year’s Winter Continues to Bail Out the Colorado River

With precipitation and snowpack falling behind normal levels for this time of year, the 40 million people served by the Colorado River have last year’s wet winter to thank for the Basin’s relative stability. Right now, the entire American West is struggling with snow drought. Snowpack for the Upper Colorado River Basin — which includes Colorado, New Mexico, Utah and Wyoming — stands at a dismal 57.7% of average as of Jan. 3.

Unusually Hot August Predicted for US West

Although the West is still enjoying the effects of an exceptionally wet winter, climate experts say that extreme heat waves will continue chipping away at the benefits. Just 9.5% of California and Nevada remained in drought on July 20, compared to 99% at the beginning of the water year in October 2022. Drought conditions persist in areas that did not receive this past winter’s deluge, including parts of southeastern California and southern Nevada.

Don’t Be Fooled by Rain and Snow, the Colorado River is Still in Serious Trouble, Experts Say

Water is rushing from Colorado’s Western Slope and into the tributaries of the Colorado River, restoring reservoirs across the American West to perhaps a semblance of their former glory. Cities, farmers, ranchers and water managers are breathing a sigh of relief at the crisis avoided this summer thanks to the robust snowfall this winter.

Bill Would Allow Colorado River Indian Tribes to Lease Water to Other Cities

As water supply continues to raise alarm bells across the American West, Sen. Mark Kelly introduced a bill that would allow central Arizona’s Colorado River Indian tribes to give portions Colorado River shares to other parts of the state.

The Colorado River Indian Tribes are a single tribal nation made up of more than 4000 Chemehuevi, Mojave, Hopi and Navajo members who live along the river in California and Arizona.

US Projections on Drought-Hit Colorado River Grow More Dire

The U.S. government released projections Wednesday that indicate an even more troubling outlook for a river that serves 40 million people in the American West.

The Bureau of Reclamation recently declared the first-ever shortage on the Colorado River, which means Arizona, Nevada and Mexico will get less water than normal next year. By 2025, there’s a 66% chance Lake Mead, a barometer for how much river water some states get, will reach a level where California would be in its second phase of cuts. The nation’s most populated state has the most senior rights to river water.

Can Water Megaprojects Save The US Desert West? (Part 1)

In the American West, water has always been a challenge. Prior to the arrival of European explorers and settlers, there’s broad evidence that droughts and water cycles heavily affected Native Americans. For example, the people who built the Gila Cliff Dwellings may have left the area when water supplies dwindled. Later settlements by the descendants of Europeans also followed water, with settlements placed near rivers so there would be something to drink and grow food with.

California Water: 10 Charts and Maps That Explain the State’s Historic Drought

A historic drought is spreading across California and much of the American West. How bad is it? Which places are most affected? What does it mean for our water supply and wildfire risk?

These 10 maps and charts tell the story.

Over the past two years, rain and snow totals in Northern California, Nevada, Utah and other parts of the West have been less than 50% of average. As this map from the Western Regional Climate Center in Reno shows, the drought is severe and widespread.

How Beef Eaters in Cities are Draining Rivers in the American West

It’s not exactly news that the rivers of the western U.S. are in trouble.

For decades, their water has been siphoned off by climate change-fueled heat and an ever-growing human demand for grassy front lawns and long showers. The biggest user of river water by far, though, is agriculture—and new research shows that across the western United States, a third of all consumed water goes to irrigate crops not for human consumption, but that are used to feed beef and dairy cattle. In the Colorado River basin, it’s over 50 percent.

The burgers, steaks, yogurt, and ice cream Americans eat in abundance, the new results show, is directly related to the overuse of river water—leaving the ecosystems and communities that depend on those rivers drastically stressed under even the best of circumstances.
