Picking up the letter nine days later, he wrote that a bad situation had deteriorated. Prior to the event, valley land was still largely owned by Mexican rancheros who held titles dating to Spanish rule. The valley’s southernmost county, Kern, is a case study in the region’s vulnerabilities. A growing body of research suggests that as the climate warms, California’s precipitation mix will shift significantly in favor of rain over snow. The valley Indians have traditions that the water occasionally rises 15 or 20 feet higher than it has been at any time since the country was settled by whites, and as they live in the open air and watch closely all the weather indications, it is not improbable that they may have better means than the whites of anticipating a great storm. “The floor of their one-story house was six weeks under water before the house went to pieces.” Steamboats “ran back over the ranches fourteen miles from the [Sacramento] river, carrying stock [cattle], etc., to the hills,” he reported. And “earthquake kits” are common gear in closets and garages all along the San Andreas Fault, where the next Big One lurks. Ingram has emerged as a kind of Cassandra of drought and flood risks in the western United States. What happens to this outlook when you heat up the atmosphere by 1 degree Celsius—and are on track to hit at least another half-degree Celsius increase by midcentury? Los Angeles flooding in the ARkStorm Scenario. Meteorologists have known for decades that those tempests that descend upon California over the winter—and from which the state receives the great bulk of its annual precipitation—carry moisture from the South Pacific. The treaty terms met with vigorous resentment from white settlers eager to shift from gold mining to growing food for the new state’s burgeoning cities. “None of us had heard of it,” she added—not even the meteorologists knew about what’s “by far the biggest disaster ever in California and the whole Southwest” over the past two centuries. Can you pitch in a few bucks to help fund Mother Jones' investigative journalism? Cahuenga Boulevard reopened late Thursday evening. Published by Bloomsbury USA. Between 1950 and 2010, Ingram and Dettinger write, atmospheric rivers “caused more than 80 percent of flooding in California rivers and 81 percent of the 128 most well-documented levee breaks in California’s Central Valley.”. Another example is the intensification of farming. As Ingram and Dettinger note, atmospheric rivers are the primary vector for California’s floods. Some trucks attempted to navigate the intersection, even as the water rose above their headlights. Oct. 22, 2020. We're a nonprofit (so it's tax-deductible), and reader support makes up about two-thirds of our budget. The Highland Avenue exit from the northbound 101 Freeway was also closed. They carry so much moisture—often more than twenty-five times the flow of the Mississippi River, over thousands of miles—that they’ve been dubbed “atmospheric rivers.”. They were shocked to learn that the previous 1,800 years had about six events that were more severe than 1862, along with several more that were roughly of the same magnitude. The state’s long-awaited high-speed train, if it’s ever completed, will place Fresno residents within an hour of Silicon Valley, driving up its appeal as a bedroom community. So an event expected to happen on average every 200 years will now happen every 65 or so. Today the valley is increasingly given over to intensive almond, pistachio, and grape plantations, representing billions of dollars of investments in crops that take years to establish, are expected to flourish for decades, and could be wiped out by a flood. The potential for boosting agriculture as a hedge against mining wasn’t lost on the state’s leaders. The garage door of one building buckled. Plant species that thrive in freshwater suggest wet periods, as heavy runoff from the mountains crowds out seawater. They concluded that “flood-related environmental contamination impacts are expected to be the most widespread and substantial in lowland areas of the Central Valley, the Sacramento–San Joaquin River Delta, the San Francisco Bay area, and portions of the greater Los Angeles metroplex.”. But Ingram and Dettinger’s work pulls the lens back to view the broader timescale, revealing the region’s swings between megadroughts and megastorms—ones more than severe enough to challenge concentrated food production, much less dense population centers. But the big ones are damaging indeed. While cattle continue to be an important part of the region’s farming mix, they no longer dominate it. They are used to it. The fast-growing metropolis was already revealing the charms we know today: “large streets, magnificent buildings,” adorned by “many flowers we [northeasterners] see only in house cultivations: various kinds of geraniums growing of immense size, dew plant growing like a weed, acacia, fuchsia, etc. He marveled at the massive impromptu lake made up of “water ice cold and muddy,” in which “winds made high waves which beat the farm homes in pieces.” As a result, “every house and farm over this immense region is gone.”. “The tops of the poles are under water!” The young state’s capital city, Sacramento, about 100 miles northeast of San Francisco at the western edge of the valley and the intersection of two rivers, was submerged, forcing the legislature to evacuate—and delaying a payment Brewer needed to forge ahead with his expedition. (WVUE) -Drone video shot Monday morning by Ken Gurley shows the extent of the flooding along the Mandeville lakefront. Apart from economic losses, “the evolution of a modern society creates new risks from natural disasters,” Jones told me. Several properties suffered damaged. Eight hours after the evacuation, highways were still jammed with slow-moving traffic. Of course, in a state beset by the increasing threat of wildfires in populated areas as well as earthquakes, funds for disaster preparation are tightly stretched. Other researchers are reaching similar conclusions. The storm is creeping along about 2 miles per hour as of the 10 pm update from the National Hurricane Center. It's us but for your ears. For more articles read aloud: download the Audm iPhone app. The dynamics of these storms themselves explain why the state is also prone to such swings. Altogether, 25 percent of the state’s buildings would be damaged. Los Angeles today Getty . The second was that they figured a smaller-than-1862 catastrophe would help build public buy-in, by making the project hard to dismiss as an unrealistic figment of scaremongering bureaucrats. They settled on two: a series of big storms in 1969 that hit Southern California hardest and a 1986 cluster that did the same to the northern part of the state. Now, loss of electricity can mean death for vulnerable populations (think hospitals, nursing homes, and prisons). “I’ve got a big pickup truck, so I think I can maneuver through about two feet, three feet, but not four feet,” resident Mars Collins told CBSLA. Easy, she said. Los Angeles County Rainfall Network. That frenzy of agricultural production means loads of chemicals on hand; every year, Kern farmers use around 30 million pounds of pesticides, second only to Fresno among California counties. The break sent thousands of gallons of water flowing down Cahuenga Boulevard, where it was pooling at the intersection with Odin Street. The entire California National Guard was put on notice to mobilize if needed—the first such order since the 1992 Rodney King riots in Los Angeles. At the time of the Great Flood, the Central Valley was still mainly cattle ranches, the farming boom a ways off. The resulting slurry cascaded through the Central Valley’s network of untamed rivers. In addition to the potentially vast human toll, there’s also the fact that the Central Valley has emerged as a major linchpin of the US and global food system. To his shocked assessment of a still-flooded and supine Sacramento months after the storm, Brewer added a prophetic coda: No people can so stand calamity as this people. The state produces nearly all of the almonds, walnuts, and pistachios consumed domestically; 90 percent or more of the broccoli, carrots, garlic, celery, grapes, tangerines, plums, and artichokes; at least 75 percent of the cauliflower, apricots, lemons, strawberries, and raspberries; and more than 40 percent of the lettuce, cabbage, oranges, peaches, and peppers. It is “more likely than not we will see one by 2060,” and it could plausibly happen again before century’s end, they concluded. The task of completing the fieldwork fell to the 32-year-old Brewer, a Yale-trained botanist who had studied cutting-edge agricultural science in Europe. In 2008, USGS produced the ShakeOut Earthquake Scenario, a “detailed depiction of a hypothetical magnitude 7.8 earthquake.” The study “served as the centerpiece of the largest earthquake drill in US history, involving over five thousand emergency responders and the participation of over 5.5 million citizens,” the USGS later reported. For most Americans, it’s easy to ignore the Central Valley, even though it’s as important to eaters as Hollywood is to moviegoers or Silicon Valley is to smartphone users. He found a city still in ruins, weeks after the worst of the rains. Inexpensive, too! Late in 1861, the state suddenly emerged from a two-decade dry spell when monster storms began lashing the west coast from Baja California to present-day Washington State. Floods, though they occur as often in Southern and Central California as they do anywhere in the United States, don’t generate quite the same buzz. The cities of 160 years ago could not boast municipal wastewater facilities, which filter pathogens and pollutants in human sewage, nor municipal dumps, which concentrate often-toxic garbage. In a November 1861 letter home, he complained of a “week of rain.” In his next letter, two months later, Brewer reported jaw-dropping news: Rain had fallen almost continuously since he had last written—and now the entire Central Valley was underwater. USGS Flood Inundation Maps, along with Internet information regarding current stage from the USGS streamgage, provide emergency management personnel and residents with information that is critical for flood-response activities, such as evacuations and road closures, as well as for post-flood … The water was at least three feet deep. Paradoxically, they are at least as much a lifeblood as a curse. Terms of Service apply. Everyone is familiar with the history of fortunes quickly made and as quickly lost. Riverside County Flood Control District. As the state’s ever-strained emergency-service agencies prepare for the Other Big One, there’s evidence other agencies are struggling to grapple with the likelihood of a megaflood. Yet floods tend to be less feared than rival horsemen of the apocalypse in the state’s oft-stimulated imagination of disaster. A California Highway Patrol spokesman summed up the scene for the Bee: Unprepared citizens who were running out of gas and their vehicles were becoming disabled in the roadway. The county houses more than 156,000 dairy cows in facilities averaging 3,200 head each. Truth #6: The only thing that can save us is…us. There was one problem: While the fictional ARkStorm is indeed a massive event, it’s still significantly smaller than the one that caused the Great Flood of 1862. It's all hands on deck for democracy. That’s dire news for our food system, because the Central Valley’s vast irrigation networks are geared to channeling the slow, predictable melt of the snowpack into usable water for farms. USGS Open-File Report. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line. The fledgling legislature had seen fit to hire a state geographer to gauge the mineral wealth underneath its vast and varied terrain, hoping to organize and rationalize the mad lunge for buried treasure.
