California Drought Update: Water Source At Sierra Snowpack Becoming Less Reliable As Climate Warms

California, long burdened by a severe drought, is coming off one if its wettest winters in almost 20 years — but that doesn’t mean its water woes will be left behind. The Sierra Nevada snowpack, which provides 60 percent of the state’s water, held an unusually immense amount of snow in January, according to data released Tuesday. That means more water for the region in the coming months. However, experts warned the abundance of the season was just an anomaly, not something to be counted on as the climate gets progressively warmer overall.

San Diego Explained: The Governor’s Water Plan and Why Locals are Wary

San Diego gets most of its water supply from far away. About a fifth of it comes from Northern California. Gov. Jerry Brown has big ideas for making sure Southern California can continue drinking water from its northern neighbor. He wants to build two 35-mile underground tunnels 150 feet underground to keep water flowing south. The price tag would be at least $17 billion. Once a big supporter of the plan, the San Diego County Water Authority is now among its biggest skeptic.

VIDEO: What Happened At Oroville Dam, And What Could Still Go Wrong

In the weeks and months to come, investigators will no-doubt probe many potential reasons for the near-catastrophic failures at Oroville Dam in February. Those will range from decisions made more than 50 years ago, to the truly extraordinary weather of 2017. But for the moment, the emergency at Oroville Dam has largely passed. The 180,000 people who were evacuated from their homes last month have returned, and construction crews continue to put millions of tons of rocks and concrete across a badly eroded hillside under the emergency spillway.

Oroville Dam Repair Crews Deal With Naturally Occurring Asbestos

Air-quality officials are working with repair crews at California’s damaged Oroville Dam spillway after the discovery of naturally occurring asbestos there. The California Department of Water Resources said Thursday that authorities found the asbestos in what it said were limited areas at the site. Work crews currently are removing tons of rocks, earth and other debris that washed to the base of the Oroville spillway last month after a large part of the spillway failed.

For Farmers Below The Oroville Reservoir, Water Still Poses A Threat

Marysville, Calif., farmer Brad Foster stood at the eroded edge of the Feather River recently and contemplated how he was going to pull his water pumps out of the soggy, collapsed river bank. “We’ll have to recover them somehow,” said Foster, 58, who owns about 500 acres of walnut orchards in Yuba County. “Those are stationary pumps. They’ve been there 50 years.” In all his years of farming, Foster said he’d never seen such severe and widespread erosion along the winding waterway. “This is not normal,” he said.

California: $400 Million Plan To Slow Largest Lake Shrinkage

California Gov. Jerry Brown’s administration on Thursday proposed spending nearly $400 million over 10 years to slow the shrinking of the state’s largest lake just as it is expected to evaporate an accelerated pace. The plan involves building ponds on the northern and southern ends of the Salton Sea, a salty, desert lake that has suffered a string of environmental setbacks since the late 1970s. During its heyday of international speed boat races, it drew more visitors than Yosemite National Park and celebrities including Frank Sinatra, Bing Crosby and the Beach Boys.

Top SD Water Official Wants Tijuana to Prioritize Sewer Water Over Desal Water

San Diego’s top water quality official worries that a new desalination plant in Mexico could worsen the decades-long problem of sewage spilling across the border into the United States. The connection between that plant and sewage spills may not be obvious. But there are three connections: wastewater management, money and politics. For years, Mexican officials have been working to build a desalination plant in Rosarito Beach that would eventually make 100 million gallons a day of Pacific Ocean water drinkable.

JPL Climatologist Announces That, for Now, El Nino is “La Nada”

Some climate models are suggesting that El Niño may return later this year, but for now, the Pacific Ocean lingers in a neutral “La Nada” state, according to climatologist Bill Patzert of NASA’s Jet Propulsion Laboratory. The latest map of sea level height data from the U.S./European Jason-3 satellite mission shows most of the ocean at neutral heights (green), except for a bulge of high sea level (red) centered along 20 degrees north latitude in the central and eastern Northern Hemisphere tropics, around Hawaii. This high sea level is caused by warm water.

 

Why CalPERS is Pouring Millions Into a Southern California Water Deal

On the edge of the Mojave Desert, beneath 1,800 acres of scrubland and tumbleweeds, California’s giant public pension fund is trying to make a killing in the water business. CalPERS is the primary owner of the Willow Springs Water Bank, an underground reservoir that could hold as much water as Folsom Lake when fully developed. Its customers, mainly a collection of Los Angeles-area water agencies, pay fees to store water beneath the Kern County soil to bolster their supplies during dry periods.
