As California’s drought worsens, state water officials are preparing to take emergency action to conserve.
The state water board is voting later this morning on new water restrictions that could impact thousands of farmers. If passed, the emergency regulations would restrict anyone from diverting water out of the Sacramento and San Joaquin Rivers and their tributaries.
A day long dreaded by hundreds of ranchers, grape growers, farmers, water providers and towns arrived Monday as the state ordered them to stop diverting water from the Russian River watershed or be fined $1,000 a day.
State regulators issued orders effective Tuesday prohibiting about 1,500 water rights holders in the upper river — including the cities of Cloverdale and Healdsburg — from diverting water in an effort to preserve rapidly diminishing supplies in Lake Mendocino.
The West has been so dry and so hot for so long that its current drought has no modern precedent, according to a National Oceanic and Atmospheric Administration meteorologist.
For the first time in 122 years of record-keeping, drought covers almost the entire Western U.S. as measured by the Palmer Drought Severity Index, said Richard Heim, a drought historian and an author of the U.S. Drought Monitor.
“It’s a very simple ‘yes,’ in terms of this drought being unprecedented,” Heim said.
The cotton’s gone.
The alfalfa barely exists.
“Can you even call this a farm?” asked Nancy Caywood, standing on a rural stretch of land her Texas grandfather settled nearly a century ago, drawn by cheap prices and feats of engineering that brought water from afar to irrigate central Arizona’s arid soil.
Cities across time have stretched to secure water. The Romans built aqueducts, the Mayans constructed underground storage chambers, and Hohokam farmers dug more than 500 miles of canals in what is now the U.S. Southwest.
Today’s cities use portfolios of technologies to conserve supply — everything from 60-story dams and chemicals to centrifugal pumps and special toilets. And yet, the cities of tomorrow will have to do more.
The president of California’s utility regulator warned a top power company Monday that power outages to prevent equipment from sparking wildfires should only be used as a last resort.
“We need specifics on where you have improved, where you are lagging and where you are focusing your resources,” California Public Utilities Commission President Marybel Batjer told representatives of San Diego Gas & Electric. “Utilities will be judged by outcome, not by plans.”
Drought conditions have prompted the building of a 750-foot wide rock barrier to prevent saltwater intrusion into the Sacramento-San Joaquin River Delta.
The California Department of Water Resources constructed the temporary barrier with 110,000 cubic yards of rock off West False River in Contra Costa County. Principal engineer Jacob McQuirk said that without the barrier, saltwater would endanger freshwater supplies in the Delta and water exports to the south.
“Every tidal cycle, that saltwater slowly propagates into the interior Delta,” he said. “Really, the beneficial uses of the interior Delta, they include agricultural supply, also interior municipal supplies.”
Hot, dry, and ‘unrecognizable’ describes July 2021.
The West boiled with record-breaking heat, and persistent drought that has left the Colorado River, Lake Mead and Lake Powell two-thirds empty, a ‘bathtub’ ring lining the shores of the largest water sources serving California.
As more frequent heat waves broke records this summer, our photojournalists documented what it looked like and how we coped.
How low can Lake Oroville go? While losing over a foot of water each day, historically low is the answer.
The lake is on track to beat its lowest recorded record: 645 feet above sea level in September 1977. Friday, it sits at 646.97 feet, just feet away from a new record.
This could drop dramatically further to 620 feet by late October, according to Molly White, Water Operations Manager for the Department of Water Resources (DWR).
California’s five-year drought that ended in 2016 was brutal, one of the most severe in history. It unfolded during historic statewide high temperatures and included the driest four-year period on record and the lowest Sierra Nevada snowpack ever recorded.
It took sacrifice and resolve, but the state made it through that challenge, thanks in part to a 25 percent reduction in urban water use mandated by former Gov. Jerry Brown.
Now drought conditions have returned — and arguably the underlying conditions are worse than those experienced five years ago. Temperatures continue to rise, setting all-time records last summer, and parched conditions have extended throughout most of the West, stressing the Colorado River basin.
