As the Colorado River’s reservoirs have declined, even larger amounts of groundwater have been drained from aquifers. Using satellite data, scientists have estimated the vast water losses.

The Colorado River Basin lost an alarming amount of groundwater over the past 20 years, a new study found. Nearly 28 million acre-feet of water has been depleted from the region, nearly the volume ...

Jay Famiglietti, a global futurist professor at Arizona State University and one of the authors of the research, said ...

THOUSAND PALMS, Calif. (KESQ) – New research is showing that groundwater from the Colorado River Basin, or CRB, is depleting more quickly than most first thought. Researchers from Arizona State ...

The Colorado River Basin’s groundwater supplies are dwindling, thanks to a combination of both natural events and human pumping activities, a new study has found. The critical Western system has ...

But as fast as the river itself is drying up, the groundwater in the area surrounding it is disappearing faster. Since 2003, the region has lost as much as 42.5 cubic kilometers of groundwater, or ...

The amount of groundwater that has been pumped out of the Colorado River Basin since 2003 is enough to fill Lake Mead, researchers report in a study published earlier this week.

The Colorado River basin has lost a Lake Mead’s worth of water in the last 20 years — and scientists say we’re passing a "critical point" where pumping groundwater will become too expensive.

They estimated that annual groundwater losses in the Colorado River Basin have averaged more than 1.2 million acre-feet—about four times larger than the amount of water the Las Vegas area is ...

The rate of water losses in the seven-state Colorado River Basin has tripled in the past decade, mainly due to intensifying groundwater over-pumping in southeast and northwest Arizona, a new study ...

Paying attention to groundwater levels, which Hall and her colleagues found accounts for most of the Great Basin’s water loss, is key in regions that export food, he said.

The amount of groundwater that has been pumped out of the Colorado River Basin since 2003 is enough to fill Lake Mead, researchers report in a study published earlier this week.
