In 2007, years into a record-breaking drought throughout the southwestern U.S., officials along the Colorado River finally came to an agreement on how they’d deal with future water shortages -- and then quietly hoped that wet weather would return.

But it didn’t.

Warming temperatures are sapping the Colorado River, the water source for more than 40 million people in the southwest. A new study finds over the last 100 years the river’s flow has decreased by more than 15 percent.

The Colorado River is running low on water. The lifeline that slakes the thirst of 40 million southwestern residents is projected to hit a historic low mark within two years, forcing mandatory cuts to water deliveries in Arizona, Nevada and Mexico.   

Facing exceptional drought conditions, cities throughout the watershed this summer have imposed mandatory water restrictions, ranchers have begun selling off cows they’re unable to feed, and the river’s reservoirs are headed toward levels not seen since they filled decades ago.

Low water levels on the Colorado River could force water shortages in Arizona, Nevada and Mexico in 2020, according to a new forecast from the U.S. Bureau of Reclamation.

A shortage on the river is tied to the level of its main reservoir, Lake Mead near Las Vegas, Nevada. If the lake drops past an elevation of 1,075 feet, water users downstream have to start cutting back how much water they use. The U.S. Bureau of Reclamation projects the lake to drop below that level next year, triggering water cutbacks in 2020.

Nuclear testing during the Cold War sent radioactive fallout far away from the actual test sites. Politicians are moving to expand who can be compensated by the government for getting sick after exposure to that fallout.

Fear can be a powerful motivator.

The mention of one plausible future scenario along the Colorado River is enough to make some water managers in the West break into a sweat. It’s called the Compact Call, and even though it’s never happened — and is years away from ever happening — its invocation conjures up dystopian imagery of a southwest battling over scarce water supplies.

Colorado River Basin Watches As Arizona Reboots Drought Talks

Water leaders in Arizona are again trying to get to “yes” on a deal that deals with drought. This would help prepare the state for future cuts to its water supply if -- and likely when -- Lake Mead drops below specific levels. A renewed effort to achieve an agreement comes after a year of anxiety and gridlock over the future of the Colorado River.

It’s early in the morning and Juli Scamardo is in chest waders, guiding me through a beaver meadow in Rocky Mountain National Park.

“These are like mazes,” she says. “It’s hard to get through a meadow and know where you’re going.”

2018 wasn't the worst winter on record for the southern Rocky Mountain region, but it was close to it.

“It was an extreme year on the dry side, widespread across the Colorado River Basin,” says Greg Smith, a hydrologist at the Colorado Basin River Forecast Center (CBRFC) in Salt Lake City.

The biggest lake in California is shrinking.

The Salton Sea occupies a hot, desert basin a short drive from the Mexico border and it’s been evaporating for years. From the air the lake is pear-shaped, bordered by an intense concentration of farms growing winter vegetables on its south end, and date palms, citrus and brussels sprouts to the north. It’s sustained by the Colorado River water that passes through these farms as irrigation before flowing into the 350 square mile lake.

The fact the lake is disappearing isn’t a shock. Its ever-widening shoreline is tied to a deal billed as a the single largest transfer of agricultural water to a municipal area in history. For at least 15 years, authorities in California have known this would happen.
