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

/in , , /by /Mercury Newsby Paul Rogers

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.

Facing ‘Dire Water Shortages,’ California Bans Delta Pumping

/in , /by /CalMattersby Rachel Becker

In an aggressive move to address “immediate and dire water shortages,” California’s water board today unanimously approved emergency regulations to temporarily stop thousands of farmers, landowners and others from diverting water from from the Sacramento-San Joaquin Delta watershed.

The new regulations — the first to take such widespread action for the massive Delta watershed stretching from Fresno to the border with Oregon — could lead to formal curtailment orders for about 5,700 water rights holders as soon as Aug. 16. The decision comes on the heels of curtailment orders issued to nearly 900 water users along the drought-stricken Russian River, with 222 more expected next week.

As California grapples with the effects of an ongoing drought, UC Berkeley researchers are studying changes in the magnitude of streamflows and drought-induced tree mortality in order to advise climate change policy.

Laurel Larsen, campus associate professor in the department of geography, is the lead scientist of the Delta Stewardship Council and provides data that informs the council’s decisions on water management in the Sacramento-San Joaquin Delta.

Funds for Pumped Storage Hydro Expected to Help Propel California’s Clean Energy Future

/in , , /by /NHA Powerhouseby Cameron Schilling Quoted: San Diego County Water Authority

Employees working at the San Diego County Water Authority and the City of San Diego likely won’t be taking much of an August vacation. Instead, many of them will be gearing up for preliminary studies, environmental reviews, and licensing activities for the proposed San Vicente Energy Storage Facility.

That’s because the facility – being proposed in partnership by the city and the Water Authority – received a shot in the arm in July 2021, when California Governor Gavin Newsom signed the state budget into law. Specifically, the budget includes $18 million in funding – enough to advance the project through initial design, environmental reviews, and the federal licensing process.

The proposed 500-MW project would be located outside of San Diego. It is designed to be closed loop or “off-river,” which means the facility will have few environmental impacts to the local area.

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.

State Cuts Off Hundreds of Russian River Growers, Ranchers and Others in Drastic Bid to Save Water

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.

A Drought Like No Other, NOAA Scientist Says

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.

Starving Cows. Fallow Farms. The Arizona Drought Is Among the Worst in the Country

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.

How to Build a Water-Smart City

/in , , /by /Bloomberg CityLab + Greenby Chris Malloy

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.

Power Shutoffs Should Be Last Resort, Regulators Warn

/in , , /by /AP Newsby Janie Har

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.”
