Oroville went down another 90K acre feet, and is only 82% of capacity. "the coming ARkStorm" It's prolly a good thing that our reservoirs had a lot of storage space. The New York Times Reprints January 15, 2011 If Quakes Weren’t Enough, Enter the ‘Superstorm’ By FELICITY BARRINGER SACRAMENTO — California faces the risk not just of devastating earthquakes but also of a catastrophic storm that could tear at the coasts, inundate the Central Valley and cause four to five times as much economic damage as a large quake, scientists and emergency planners warn. The potential for such a storm was described at a conference of federal and California officials that ended Friday. Combining advanced flood mapping and atmospheric projections with data on California’s geologic flood history, over 100 scientists calculated the probable consequences of a “superstorm” carrying tropical moisture from the South Pacific and dropping up to 10 feet of rain across the state. “Floods are as much a part of our lives in California as earthquakes are,” said Lucy Jones, the chief scientist for the United States Geological Survey’s multi-hazards initiative, adding, “We are probably not going to be able to handle the biggest ones.” The geological survey estimates that such a storm could cause up to $300 billion in damage. The scientists’ models estimate that almost one-fourth of the houses in California could experience some flood damage from one. The conference was convened by the geological survey, the Federal Emergency Management Agency and the California Emergency Management Agency to help disaster-response planners draft new strategies to limit the storms’ impact. Climate scientists have for years noted that the rising temperature of the earth’s atmosphere increases the amount of energy it stores, making more violent and extreme weather events more likely. Californians have learned to expect earthquakes the way Floridians expect hurricanes. (A minor earthquake, with a preliminary magnitude of 4.1, rattled windows in the southern part of the San Francisco Bay area about a week ago.) The existing engineering systems that dispose of floodwater are so efficient that the effects of moderate storms often go unnoticed, Dr. Jones said. So while many Californians know whether they live or work close to an earthquake-prone fault and what to do should there be a serious quake, few realize that the state could be hit by storms that at their worst could rival the largest hurricanes that devastate the Gulf Coast and the southeastern Atlantic Seaboard. Yet vast floods have also been documented, both through tree-ring data and more modern historical records. Marcia K. McNutt, the director of the geological survey, said that 150 years ago, over a few weeks in the winter of 1861-62, enough rain fell to inundate a stretch of the Central Valley 300 miles long and 20 miles wide, from north of Sacramento south to Bakersfield, near the eastern desert. The storms lasted 45 days, creating lakes in parts of the Mojave Desert and, according to a survey account, “turning the Sacramento Valley into an inland sea, forcing the state capital to be moved from Sacramento to San Francisco for a time, and requiring Gov. Leland Stanford to take a rowboat to his inauguration.” Just like a major earthquake, a superstorm could be a severe blow to the state’s agriculture and to the water-supply system that now diverts water from the north to Southern California. Dr. Jones said in an interview that improved satellite imagery available in recent years allowed scientists to clearly identify what they call “atmospheric rivers” — moisture-filled air currents up to 200 miles wide and 2,000 miles long, which flow from tropical regions of the Pacific Ocean to the West Coast. The West Coast winter weather systems popularly known as the Pineapple Express, air currents carrying moisture from the Hawaiian Islands are just one moderate subset of these rivers, Dr. Jones said. The abbreviation for atmospheric river, A.R., gave the geological survey the root of its name for these major weather events, which they call ARk storms. nytimes.com In 1860 California had been a state for 10 years. The state hired an excellent team of men from Yale, including Josiah Whitney and William Brewer, for a long term in-depth investigation of the state’s resources. They were just two years into their studies when the great flood of 1862 bankrupt the state, and soon thereafter terminated their lofty project. A fourth of the state’s economy was destroyed. This flood transformed the Sacramento Valley into an inland sea, covering the tops of telegraph poles with steamboats passing over the farmlands to deliver goods and rescue survivors. The Santa Ana River formed two large lakes – one in the Inland Empire and another in the flood plain of Orange County. Probably the only definite high water mark in Southern California is at the Aqua Mansa, just south of the present city of Colton. Hydrologic studies at Aqua Mansa, document a discharge in 1862, three times the magnitude of anything since. In Northern California, a high-water measurement on the American River in 1862, suggesting a very high flow, appears to be ignored. redlandsfortnightly.org January 10, 1862 - Due to flooding, newly elected Governor Leland Stanford had to travel to his inauguration at the Capital in a rowboat.
