When the nation’s largest desalination plant opened in Carlsbad, California, in 2015, people across the country were watching to see how it increased water supplies as groundwater dwindled, reservoirs dried up, and drought ravaged the Golden State.
Nearly 10 years later, the plant has demonstrated how seawater desalination can play a pivotal role in achieving water security.
Two winters’ worth of snow has already fallen in the Sierra Nevada since Christmas, pulling California from the depths of extreme drought into one of its wettest winters in memory.
But as a series of tropical storms slams the state, that bounty has become a flood risk as warm rains fall on the state’s record snowpack, causing rapid melting and jeopardizing Central Valley towns still soggy from January’s deluges.
Once mired in drought, California now has too much of a good thing and has opened spillways on key reservoirs as the first of two atmospheric rivers made landfall Thursday afternoon.
The Golden State activated the Flood Operation Center ahead of the incoming storms, to notify officials of high water levels and support local flood relief efforts.
PETALUMA, Calif.—Neil McIsaac has something many other dairy farmers here don’t: a storm-runoff capture system that can provide backup water for his herd when local reservoirs go dry, as they did last year.
Already, he and others involved in the project say it has proven its worth. It has captured 670,000 gallons so far this winter, enough to slake the thirst of his 700 cows for a month, Mr. McIsaac said.
With back-to-back storms to hit California in the coming days, state officials are scrambling to make strategic releases from key reservoirs in hopes of preventing a repeat of the flooding that killed nearly two dozen people in January.
At least 10 rivers are forecast to overflow from the incoming “Pineapple Express” storm, which is expected to drop warm, heavy, snow-melting rain as it moves from the Central Coast toward the southern Sierra beginning Thursday night into Saturday.
Millions of Californians were under threat on Thursday from an approaching storm that could trigger intense downpours and widespread flooding in many parts of the state, including in some mountainous areas already buried under a near-record snowfall.
After a weeks of unusually bad weather on the West Coast, the storm known as an atmospheric river could dump as much as 3 inches (8 cm) of rain in the San Francisco Bay area and across the Central Coast from Thursday through the weekend, the National Weather Service (NWS) said in its forecast.
States that use water from the Colorado River are caught in a standoff about how to share shrinking supplies, and their statements about recent negotiations send mixed messages. California officials say they were not consulted as other states in the region drew up a letter to the federal government with what they called a “consensus-based” set of recommendations for water conservation. Leaders in states that drafted the letter disagree with that characterization.
After three nasty years, the La Niña weather phenomenon that increases Atlantic hurricane activity and worsens western drought is gone, the National Oceanic and Atmospheric Administration said Thursday.
That’s usually good news for the United States and other parts of the world, including drought-stricken northeast Africa, scientists said.
A particularly wet season has swept across the southwestern U.S., a region that has suffered under a severe megadrought for over two decades. But what has this meant for Colorado River reservoir Lake Mead?
Storms of rain and snow have hit California particularly badly in recent months, and have spread into neighboring states like Nevada. Reservoirs like Lake Mead rely on seasonal snowmelt and rainfall.
The Supreme Court is extremely strict about what can be brought into its chambers during oral arguments. In addition to obvious items like guns and knives, visitors must leave just about every other personal item outside when they enter. Cameras, cell phones, laptops, and the like are left outside—even if you’re a reporter. No snacks or drinks can be brought in. Not even water.
