Is California’s drought over? Water providers still predict shortages next year

December has delivered a powerful punch of storms to California. But the wet weather comes with a dry dose of reality: The state’s largest reservoirs remain badly depleted, projected water deliveries are low, wells are drying up, and the Colorado River’s water, already diminished by a megadrought, is severely overallocated.  Throughout California, urban water managers are bracing for a fourth consecutive drought year. Nearly one out of every five water agencies — 76 out of 414 — in a recent state survey predict that they won’t have enough water to meet demand next year. That means they are likely to impose more severe restrictions on customers, with some Southern California providers considering a ban on all outdoor watering.  While December’s rain and snow show promise, water managers remember the same thing happened last year — epic early storms followed by the driest January through March in California’s recorded history. ... ”  Read more from Cal Matters here: Is California’s drought over?

Too soon to know how Sierra Nevada snowfall will impact California’s ongoing drought

For the second weekend in a row, Sacramento and the Sierra Nevada mountains saw back-to-back storms bringing rain to the valley and snow to the hills.  Despite the recent wet weather, including snow intense enough to snarl mountain travel in the Sierra this weekend, California is still grappling with a number of drier-than-usual winters and persistent drought. So how much did these storms help?  CapRadio’s Mike Hagerty spoke with Dr. Andrew Schwartz, the lead scientist and manager of UC Berkeley’s Central Sierra Snow Laboratory at Soda Springs near Donner Pass, about how much snow we got and if it made a dent in the state’s drought. … ”  Read more from Capital Public Radio here: Too soon to know how Sierra Nevada snowfall will impact California’s ongoing drought

Report: Sharing the cost: Accelerating water resilience through infrastructure finance in California

Beyond the intensifying drought and widening infrastructure inefficiencies, there are billions of dollars worth of unmet operation and maintenance costs and system improvements currently to be found in the State Water Project and Central Valley Project, and throughout California. Accelerating water resilience throughout the state will require the state to gather better information regarding gaps in local water infrastructure project funding, operations and maintenance, and delivery systems. Additionally, the state will need to work with regions to facilitate the coordination, governance, and capacity-building capabilities necessary to harness innovative financing mechanisms that enhance economic growth and improve the quality of life for the residents in urban, rural, and agricultural communities. … ”  Read more and download report from the Milken Institute here: Report: Sharing the cost: Accelerating water resilience through infrastructure finance in California

Illegal pot grows are making forests high on water contamination

Clandestine cannabis grows are messing with water quality in four separate national forests, harming potential drinking water supplies downstream of the illegal operations.  The U.S. Forest Service has long suspected that these secretive “grows” are causing harm to wildlife, but the impacts are more insipid than that.  What the federal agency found: A six-year study by Forest Service law enforcement, investigative ecologists and other partners found the fallout of illegal cannabis operations is doing more than hurting terrestrial wildlife, including the federally protected northern spotted owl and Pacific fisher. After the extensive monitoring, researchers found illegal and banned pesticides have been unexpectedly detected in surface waters below these sites. … ”  Read more from Deseret News here:  Illegal pot grows are making forests high on water contamination

Pollution cleanup method destroys toxic “forever chemicals”

An insidious category of carcinogenic pollutants known as “forever chemicals” may not be so permanent after all.  University of California, Riverside, chemical engineering and environmental scientists recently published new methods to chemically break up these harmful substances found in drinking water into smaller compounds that are essentially harmless.  The patent-pending process infuses contaminated water with hydrogen, then blasts the water with high-energy, short-wavelength ultraviolet light. The hydrogen polarizes water molecules to make them more reactive, while the light catalyzes chemical reactions that destroy the pollutants, known as PFAS or poly- and per-fluoroalkyl substances.  This one-two punch breaks the strong fluorine-to-carbon chemicals bonds that make these pollutants so persistent and accumulative in the environment. In fact, the molecular destruction of PFAS increased from 10% to nearly 100% when compared to other ultraviolet water-treatment methods, while no other undesirable byproducts or impurities are generated, the UCR scientists reported in a paper recently published in the Journal of Hazardous Materials Letters. … ”  Read more from the UC Riverside here: Pollution cleanup method destroys toxic “forever chemicals”

Solar panels planned on aqueduct to save power and energy

California’s newest infrastructure project will hit two proverbial climate birds with one stone. And Los Angeles city officials just decided last week to try one of its own.  The plan is to cover some of California’s exposed water canals with solar panels. It will prevent evaporation amidst the state’s historic drought. It will also create renewable energy as the state attempts to meet lofty decarbonization goals.The idea gained traction in California after researchers at UC Merced studied the possibility on the state’s canals last year.  “If we put solar panels over all 4000 miles of California’s open canals, we estimated we could save 65 billion gallons of water annually,” says Brandi McKuin, who led the study. “That’s enough for the residential water needs of 2 million people – enough to irrigate 50,000 acres of farmland.” ... ”  Read more from the Public News Service here: Solar panels planned on aqueduct to save power and energy

California’s 2022 fire season: “A remarkably different year”

This year’s fire season was relatively quiet—a welcome change of pace for fire-weary Californians. But what does it mean in the larger scheme of things? We asked UC Berkeley professor and PPIC Water Policy Center research network member Scott Stephens for insights.  Q: The 2022 fire season has seemed much less intense than in the past few years. Does the data bear that out?  A: It has indeed been a remarkably different year. A couple of factors led to that: we didn’t have lightning igniting hundreds of fires simultaneously, and the weather was a little better, though it certainly wasn’t perfect—we had a six or seven day period of the highest temperatures ever recorded in California. Luckily that heat didn’t come with wind this year. We have seen more prescribed burns and thinning in the last five years, and some of these fuel treatments reduced fire behavior to allow for more effective suppression. Also, CalFire increased resources for initial attack, picking up fires as early as possible, and that helped—though we all know that’s not a solution to the situation we’re in. But it was a factor. … ”  Read more from the PPIC here: California’s 2022 fire season: “A remarkably different year”

Southern California coastal towns are losing valuable sand, putting some beaches at risk

Gone are the bonfires, the volleyball nets and the sunbathers from some sand-depleted beaches in Southern California.  Memories are all that’s left, as the force of the ocean’s waves menace homes, parking lots and an important rail line that hugs the coast. In place of plush sand, walls of gray boulders now serve as barriers against the sea where beach towels once lay.  Millions of residents and tourists flock year-round to Southern California’s iconic coast. Each year, Los Angeles County beaches attract more than 50 million visitors; an estimated 6 million people visit Laguna Beach alone each year.  But the coastal landscape is dramatically changing in Southern California as the sand disappears from several beloved beaches. One study predicts two-thirds of the beaches could be gone by 2100 if no one intervenes.  And Southern California is not alone. More than half the coastline in Florida is critically eroded. Coastal dunes in New Jersey have been devastated by storms. … ”  Read more from the OC Register here: Southern California coastal towns are losing valuable sand, putting some beaches at risk

Colorado River users set to meet, but water deal seems a ways off

Photo by Nikola Knezevic on Unsplash

As Western water managers get set to gather in Las Vegas this week, a long-sought deal to curtail water use along the cratering Colorado River still seems a ways off.  Nearly six months have passed since Bureau of Reclamation Commissioner Camille Touton first asked the Western states to come up with a plan to cut back on water use from the river next year by as much as 30 percent, but a cohesive proposal from the seven states that pull from the Colorado that supplies water to some 40 million people has yet to emerge.  Things have only gotten worse along the river since Touton’s request, and that decline shows no signs of slowing down. Reclamation officials said during public meetings in recent weeks that without any adjustments to current operations on the river, Lake Powell could drop to a point where Glen Canyon Dam would not be able to generate hydropower as early as the middle of next year while Lake Mead could drop another 100 feet — putting Hoover Dam’s power generation capabilities in jeopardy — by spring of 2025. … ”  Read more from the Las Vegas Review-Journal here: Colorado River users set to meet, but water deal seems a ways off

A dried-up Rhine River threatened to tip Germany’s economy into recession, because cargo ships could not carry standard loads. And the Las Vegas strip turned into a river and flooded casinos, chasing customers away. It seems that such water disasters pepper the news daily now.  Many businesses have long lobbied against changing their practices to safeguard the environment, by refusing to implement pollution controls, take climate action or reduce resource use.

Which wetlands to protect? Supreme Court will soon decide

” … Currently, the law governing wetland protection is muddled. The Clean Water Act of 1972 holds that federal protections apply to navigable waters, which are referred to as the “waters of the United States” (known as WOTUS). Wetlands often aren’t navigable, yet they help keep navigable waters clean and healthy. The Clean Water Act left it to federal regulators to determine exactly what should be should be included under “waters of the United States,” and court decisions have so far failed to clarify the issue.  A previous Supreme Court case, in 2006, only added to the confusion when the opinion split three ways. A plurality of justices, in an opinion written by Justice Antonin Scalia, found that a “continuous surface connection” was the test to define a wetland to find protection under the Clean Water Act. But a separate opinion, by Justice Anthony Kennedy, found there needed to be a “significant nexus” to navigable waters, which means that if there wasn’t an obvious surface connection, research was needed to show that the wetlands played a role in assuring the integrity of the larger body of water, for wildlife habitat or for other ecological value. Subsequent decisions by lower courts have said that either Kennedy’s opinion should be followed or that either opinion may be used. … ”  Read more from Yale e360 here: Which wetlands to protect?

Latest international water satellite packs an engineering punch

Set for a Thursday, Dec. 15 launch, the Surface Water and Ocean Topography (SWOT) satellite promises to provide an extraordinary accounting of water over much of Earth’s surface. Its measurements of fresh water and the ocean will help researchers address some of the most pressing climate questions of our time and help communities prepare for a warming world. Making this possible is a scientific instrument called the Ka-band Radar Interferometer (KaRIn).  Years in development, the instrument has been designed to capture very precise measurements of the height of water in Earth’s freshwater bodies and the ocean. KaRIn will measure the height of water in the ocean, “seeing” features like currents and eddies that are less than 13 miles (20 kilometers) across – up to 10 times smaller than those detectable with other sea level satellites. It will also collect data on lakes and reservoirs larger than 15 acres (62,500 square meters) and rivers wider than 330 feet (100 meters) across. … ”  Read more from NASA here: Latest international water satellite packs an engineering punch
