Wildfires Threaten Urban Water Supplies, Long After the Flames Are Out

/in , , /by /The New York Timesby Henry Fountain

Wrangling a 25-foot-long tube of straw up a steep hillside studded with charred pine trees, three volunteer workers placed it in a shallow trench that had been dug along the slope.

Locked in place with wooden stakes, the sausage-like tube was part of an effort to avoid a potentially large and long-term problem with the drinking water for hundreds of thousands of people to the east. The tube, with others above and below it, should help prevent the hillside, made unstable last fall by a large wildfire, from choking the water supply with sediment when the thunderstorms known as monsoon rains arrive as expected this summer.

San Jose: New Drought Rules Limit Lawn Watering to Two Days a Week

/in , , /by /The Mercury Newsby Paul Rogers

San Jose’s largest retail water provider on Tuesday announced new rules aimed at increasing water conservation as the state’s drought worsens and reservoir levels drop — chief among them a limit on watering lawns and landscaping to no more than two days a week.

San Jose Water Company, which serves 1 million people who live in San Jose, Campbell, Los Gatos, Saratoga, parts of Cupertino and Redwood Estates, said the new rules take effect immediately.

Less Water May Mean Less Power for California

/in , , /by /NBC7 San Diego by Joe Little Quoted: San Diego County Water Authority

The summer of 2021 could go down as one of the hottest and driest summers in California’s history.

“In Northern California, where we get a lot of our water supply, it has been one of the driest 18 months on record in 120 years,” said Goldy Herbon, a Senior Water Resources Specialist for the San Diego County Water Authority.

Herbon said there is no snowpack in Northern California and the Colorado River is almost down to 60% of its normal water levels.

That’s usually very bad for counties that import a lot of their water. However, Herbon said the San Diego County Water Authority and its member agencies like the city of San Diego have invested billions of dollars in infrastructure improvements over the last 30 years that have given San Diego County enough to withstand any potential water restrictions brought on by drought.

Water Shortages: Why Some Californians are Running Out in 2021 and Others Aren’t

/in , , /by /CalMattersby Rachel Becker Mentioned: San Diego County Water Authority

In Los Angeles, people have been hearing about the dangers of drought for decades. But in this land of infinity pools and backyard putting greens — better suited for rattlesnakes and scrub — water never seems to run out.

Yet little Redwood Valley in Mendocino County, which gets a bountiful 38 inches of rain in an average year and sits near the headwaters of the Russian River, has been devastated by this year’s drought. Each resident has been told to use no more than 55 gallons per day — enough to fill a bathtub and flush a toilet six times.

And in San Jose, where less than half of its usual rain has fallen this year, people have been asked to cut water use by 15% — a target that could become mandatory if locals fail to comply.

When it comes to the impact of drought, location is key. Rain and snow vary greatly across California’s myriad microclimates, leaving some towns, mostly in the north, accustomed to yearly refills of their rivers, reservoirs and aquifers. Others farther south have fewer natural supplies of their own, and in parts of the Central Valley, the drought never really left.

NASA Images Show Effects of Drought on California’s Largest Reservoirs

Satellite images recently released by NASA show how drought has affected Northern California’s Shasta Lake and Lake Oroville, the largest reservoirs in the state. NASA compared images taken earlier in June with images taken in the summer of 2019 to illustrate how water levels have declined over the two-year period.

Where Did Sierra Snow Go this Spring? Not Into California Rivers and Water Supplies

/in , , /by /The Mercury Newsby Paul Rogers

California’s severe drought was made worse this year by a shocking surprise.

Every year, much of the drinking water that flows through the taps of millions of Californians begins in the Sierra Nevada. Snow and rain fall on the vast mountain range during the winter months, and the water moves downhill into streams, rivers and reservoirs in the spring and summer.

But this year, in a trend that startled water managers, much of that runoff simply vanished.

These Parts of California are Most Vulnerable to Drought

/in , , /by /San Francisco Chronicleby Yoohyun Jung

As California’s drought continues to intensify, thousands of water agencies across the state are now facing restrictions. For many large water districts, like those serving San Francisco, Oakland and Berkeley, this isn’t a huge problem, as they have ample water reserves. But many rural areas of the state and smaller water systems are more vulnerable, and the drought could have devastating consequences.

California’s last drought, which lasted from 2011 to 2017, was particularly hard on rural communities and small water suppliers, state officials say. In 2016, the California legislature passed a law tasking the state’s Department of Water Resources to identify the most vulnerable communities and make recommendations to help them plan for emergencies.

Against Expectations, Southwestern Summers Are Getting Even Drier

/in , , /by /The New York Timesby Henry Fountain

The Southwest, already the driest region in the United States, has become even drier since the mid-20th century, particularly on the hottest days, according to new research. Humidity has declined in summers over the past seven decades, the research showed, and the declines have accelerated since 2000, a period of persistent drought in the region. Extreme heat coupled with lower humidity increases wildfire risk, said Karen McKinnon, a climate scientist at the University of California, Los Angeles, and lead author of a paper in Nature Climate Change describing the research and findings.

City Approves Purchase of Desalination Unit

/in , /by /Fort Bragg Advocate-Newsby Robin Epley

The Fort Bragg City Council’s special meeting on Monday went fairly quickly — all of 10 minutes — and unanimously approved the purchase of a desalination and reverse osmosis machine for no more than $335,818.50.

At the last city council meeting, city staff requested the council set aside $600,000 to pursue various options during this summer’s expected drought, including hurdles with sourcing and permitting.

The flow in the Noyo River, which is the city’s primary water source in summer and fall months, is at levels below the worst drought year on record, 1977.

San Diego Region is Drought-Safe This Summer

/in , /by

Statewide drought conditions are highlighting the value of regionally and locally controlled water supplies in San Diego County, where the Water Authority announced June 21 that the region is protected from drought impacts this summer, and through 2045, despite continued hot and dry conditions. No shortages or regional water-use mandates are in the forecast – the result of three decades of strategic investments that create an aquatic safety net for San Diego County’s $253 billion economy and our quality of life.

The region’s diversified water supply portfolio includes highly reliable and locally controlled supplies, including desalinated seawater from the Claude “Bud” Lewis Carlsbad Desalination Plant. It also includes high-priority, low-cost, conserved water from the Quantification Settlement Agreement, the nation’s largest conservation-and-transfer agreement. The combination offers significant protection against droughts and other emergencies even during multiple dry years.

San Diego region is “drought-safe” thanks to water-smart practices

I offer my sincere thanks to all San Diegans for everything you have done to make sure that we have enough water to meet the region’s needs now and for decades into the future. You have invested through your water bills and your water-smart practices, and those efforts are paying off in tangible ways.

At the same time, it’s important that we all continue embracing water-use efficiency strategies that have become part of our regional ethic. Simple but important steps include turning off the faucet while brushing teeth, fixing irrigation system leaks, and using hoses with automatic shut-off nozzles.

Thanks again for all you do, and remember to stay water-smart this summer!
