The seven states that rely on the Colorado River must come up with a plan to cut 2 to 4 million acre-feet of water use.
By mid-August.
And if they don’t, the federal Bureau of Reclamation will act for them.
It’s no secret that San Diego County’s top water managers are deeply frustrated with California’s new conservation rules, even as drought continues to ravage the American Southwest.
The San Diego County Water Authority, the region’s wholesaler, has repeatedly lobbied the state for an exemption to prohibitions on watering commercial and other landscapes that go into effect this month.
The Colorado River is in crisis — one deepening by the day.
It is a powerhouse: a 1,450-mile waterway that stretches from the Rocky Mountains to the Sea of Cortez, serving 40 million people in seven U.S. states, 30 federally recognized tribes and Mexico. It hydrates 5 million acres of agricultural land and provides critical habitat for rare fish, birds and plants.
After water levels at a California dam fell to historic lows this summer, the main hydropower plant it feeds was shut down. At the Hoover Dam in Nevada — one of the country’s biggest hydropower generators — production is down by 25%. If extreme drought persists, federal officials say a dam in Arizona could stop producing electricity in coming years.
Severe drought across the West drained reservoirs this year, slashing hydropower production and further stressing the region’s power grids. And as extreme weather becomes more common with climate change, grid operators are adapting to swings in hydropower generation.
Federal officials project more bad news for the drought-stressed Colorado River, which provides water to Las Vegas and much of the Southwest.
The Bureau of Reclamation issued a report last week saying there is a high likelihood over the next few years that California, the river’s largest water user, will join Nevada, Arizona, and Mexico in seeing cuts to its allocation.
Federal officials on Monday issued the first-ever “Level 1” shortage declaration for the massive reservoir of Lake Mead on the Colorado River, triggering major water cuts for Arizona, Nevada and Mexico.
The cuts for water users downstream from Hoover Dam will begin in October, the U.S. Bureau of Reclamation said in a statement.
U.S. officials on Monday declared the first-ever water shortage from a river that serves 40 million people in the West, triggering cuts to some Arizona farmers next year amid a gripping drought.
Water levels at the largest reservoir on the Colorado River — Lake Mead — have fallen to record lows. Along its perimeter, a white “bathtub ring” of minerals outlines where the high water line once stood, underscoring the acute water challenges for a region facing a growing population and a drought that is being worsened by hotter, drier weather brought on by climate change.
Federal officials on Monday issued the first “Level 1” shortage declaration for the massive reservoir of Lake Mead on the Colorado River, triggering major water cuts for Arizona, Nevada and Mexico.
The cuts for water users downstream from Hoover Dam will begin in October, the U.S. Bureau of Reclamation said in a statement.
“Today’s announcement of a Level 1 Shortage Condition at Lake Mead underscores the value of the collaborative agreements we have in place with the seven basin states, tribes, water users and Mexico in the management of water in the Colorado River Basin,” said Reclamation Deputy Commissioner Camille Touton.
But she warned that other reservoirs were short as well and “we have not eliminated the potential for continued decline of these critically important reservoirs” during what has become a historic drought.
Total Colorado River system storage is currently at 40% of capacity, down from 49% at this time last year.

Intensifying drought conditions in California and historically low water levels at the Oroville Dam on Aug. 5 forced the state’s Department of Water Resources to shut down the 644-MW Edward Hyatt Power Plant—the fourth-largest energy producer of all California’s hydroelectric facilities.
While the current drought is affecting 95% of the West, it is bearing down severely in California and in the Colorado River Basin. Multiple reservoirs monitored by the U.S. Bureau of Reclamation are “substantially” affected. The federal agency reported on Aug. 8 that at least six of its 44 major reclamation reservoirs—including Hoover Dam and Glen Canyon Dam—have now fallen to their lowest storage values in the last 30 years.
