California Threats Jump From Fires To Floods As Wet Season Hits

California’s climate threats could soon be jumping from wildfires and blackouts to floods and mudslides as the wet season kicks into gear.

About half the water that falls in the state in any given year does so in the 90 days between Dec. 1 and the end of February. Too much rain has at times meant catastrophic floods and dangerous mudslides. Too little threatens agriculture with drought, and potentially creates a tinderbox effect in the year ahead.

County Approves Special Agricultural Water Program

The San Diego County Water Authority board recently approved a permanent, special agricultural water rate structure that offers lower rates to farmers in exchange for lower water supply reliability.

Unlike the current, temporary program, the new program will let new participants join as a way to strengthen the region’s multi-billion-dollar agriculture industry.

Baja California Water Supplies Remain at Critical Levels

Tijuana and Rosarito residents may have gotten a brief reprieve from scheduled water shut-offs, but the delivery of water throughout Baja California is a vulnerable system in need of urgent repairs, state and water officials stressed this week.
Like San Diego, Tijuana gets most of its water supply — at least 95 percent — from the Colorado River. It’s delivered through a single aqueduct that carries the water all the way across the state, including up and over La Rumorosa, a mountain pass more than 4,000 feet above sea level.

Pattern Change to Bring Drier Trend to Most of California Through Mid-December

Several storms have barreled across much of California since before Thanksgiving. But now, a shift in the weather pattern looks to bring calmer weather.

Storm after storm dove across the state over the past several weeks, delivering rain, wind and mountain snow.

The jet stream, which helps to influence the track storm systems take, was a big part of the reason for the recent storminess.

How a Closed-Door Meeting Shows Farmers are Waking Up on Climate Change

The meeting last June in a wood-beamed barn in Newburg, Md., an hour due south of Washington, had all the makings of a secret conclave. The guest list was confidential. No press accounts were allowed. The topic was how to pivot American agriculture to help combat climate change — an issue so politically toxic that the current administration routinely shies away from promoting crucial government research on the issue.

But this meeting represented a change. It was hosted by the U.S. Farmers and Ranchers Alliance, a group made up of the heavyweights in American agriculture. It brought together three secretaries of agriculture, including the current one, Sonny Perdue, among an A-list of about 100 leaders that included the president of the American Farm Bureau Federation — a longtime, powerful foe of federal action on climate — and CEOs of major food companies, green groups and anti-hunger advocates.

Coupling Pumped Hydro With Renewables and Other Storage Technologies

The combination of pumped hydro with other storage technologies can increase renewables penetration, improve operational safety and reduce maintenance costs at large-scale hydropower plants, according to new research. The study also focuses on techniques to determine the optimal size of renewables-based pumped hydro storage systems.

Pumped hydro is highly cost competitive as a large-scale energy storage solution, according to a recent report by the San Diego County Water Authority. The higher capital costs of pumped storage technology versus battery storage are outweighed by the longer lifetime of pumped storage, which gives it a lower levelized cost, the authority said.

Amid the Wasteland of the Salton Sea, a Miraculous But Challenging Oasis is Born

It came as a bittersweet surprise to biologists and government agencies monitoring the steadily shrinking Salton Sea’s slide toward death by choking dust storms and salt.

Thousands of acres of exposed lake bed have become, of all things, the unintended beneficiaries of lush marshlands that are homes for endangered birds and fish at the outlets of agricultural and urban runoff that used to flow directly into the Salton Sea.

Rancho Cucamonga-Based Water District Reports Data Breach

Unauthorized access of a server used to process payments for a San Bernardino County water utility may have exposed some customers’ billing information to theft, authorities disclosed last week.

Central Square, an outside vendor for the Cucamonga Valley Water District, reported that a server handling one-time credit card transactions for the utility had been breached between Aug. 26 and Oct. 14, CVWD officials said Dec. 4 in a post on the utility website.

With Water Crisis Over, Poway Businesses Regroup

Restaurants in Poway reopened Saturday morning after six days of darkness, with owners and employees happy to be back at work, but upset about the costly interruption to their businesses and lives.
A week ago, restaurants, bars and other businesses that handled food — about 190 in all — were ordered to close by the county’s health department after the state issued a boil-water advisory for the entire city.

Recent Storms Bolster County Water Supply
