‘A very significant emergency’: California’s deadly, record-setting storms are about to get an encore

California storms: Reservoirs are filling quickly, boosting water supplies after years of drought

Across the Bay Area and California, the past two weeks of soaking storms have brought mudslides, floods and power outages. They’ve also brought something not seen in years — billions of gallons of water rushing into reservoirs, renewing hopes that the state’s relentless drought may come to an end this spring.  Six atmospheric river storms since the end of December have dumped half a year’s worth of rain on San Francisco, Oakland, Sacramento and other Northern California cities in two weeks. The ferocious weather has saturated soils and bolstered runoff while also smothering the Sierra Nevada in snow, leaving the statewide snowpack Wednesday at a breathtaking 226% of its historical average and setting up reservoirs to receive more water when it melts later this spring.  “There’s no getting around it. This is great for reservoir storage,” said Jeffrey Mount, a professor emeritus at UC Davis and senior fellow at the Public Policy Institute of California’s water center. “It will clearly help the drought. We are likely to have full reservoirs this spring because there’s such a huge snowpack.” ... ”  Read more from the San Jose Mercury News here: California storms: Reservoirs are filling quickly, boosting water supplies after years of drought

‘Endless stream’ of new storms hits California again this week. What to expect

The seventh atmospheric river storm since Christmas hit California on Wednesday, and more flooding is possible as two more are forecast through the Martin Luther King Jr. holiday weekend, officials said.  Speaking to reporters in hard-hit Capitola, a beach town east of Santa Cruz devastated by storm damage, Gov. Gavin Newsom on Tuesday warned about more destruction to come. By Wednesday, the number of confirmed storm-related fatalities rose to 19.  “We’re not out of the woods,” Newsom told reporters. “This place is soaked. … These conditions are serious, and they’re deadly.” ... ”  Read more from the LA Times here: ‘Endless stream’ of new storms hits California again this week.

Why California is being deluged by atmospheric rivers

California is taking a beating from what the National Weather Service has called a “seemingly never ending parade” of strong storm systems, which started late last December and are still coming. Called atmospheric rivers, they are long, narrow currents of exceptionally wet air that shoot across the ocean, capable of dumping massive volumes of rain or snow on landfall.   Although these storms deliver much of the West’s precipitation, they also cause most of the region’s flooding, with associated economic damages as high as $1 billion a year. … More atmospheric rivers are predicted in the coming days, raising fears of flash floods across California—and of catastrophic mud and debris flows where recent wildfires have created 21 burn scars around the state.  … To learn more about why these storms are hitting California, as well as their potential dangers and benefits, Scientific American spoke with extreme weather expert Katerina Gonzales, who studied atmospheric rivers as a graduate student at Stanford University and is now a postdoctoral associate at the University of Minnesota. … ”  Read more from Scientific American here: Why California is being deluged by atmospheric rivers

Is California’s drought over? Here’s what you need to know about rain, snow, reservoirs and drought.

The year 2023 began with a historic bang — record precipitation and disastrous flooding throughout much of California. Parched watersheds soaked up the first rains, but soon became waterlogged. Runoff accelerated. Sodden hillsides collapsed. Rural levees burst and rivers spilled their banks. Towns went underwater. People died.  Meanwhile, the Pacific Ocean continued to whip up more atmospheric rivers and “bomb cyclones,” and one after another, these intense storms pummeled California. Abruptly, a state emerging from the dust of three painfully dry years was inundated with more water than it knew what to do with.  But the wet and wild weather over the past dozen days won’t end the drought, at least not yet, and it won’t undo the driest period in the West in the past 1,200 years.  About 71% of California is still experiencing “severe” drought, according to the National Integrated Drought Information System. … ”  Read more from Cal Matters here: Is California’s drought over?

California snowpack outpacing highest year on record

California’s snowpack levels continue to rise, now sitting at more than 225% of the average for this time of year. It’s welcome news to a state slogging through a prolonged drought, and with more winter storms headed this way, that number is sure to climb.  Snowpack levels in the Sierra Nevada approached 200% of the yearly average on Monday, driven by multiple atmospheric rivers over the last several weeks.  On Wednesday, that total continued to climb to 226% of the yearly average for Jan. 11, according to the National Weather Service. ... ”  Read more from KTLA here: California snowpack outpacing highest year on record

Calif. flushed 95% of incoming Delta water to Pacific Ocean during Monday’s massive storm

After several years of severe drought, the intense storms over the last week would seemingly be a godsend to California and go a long way toward fixing the state’s water problems.  But the opposite is happening as the state is flushing out the vast majority of the incoming water into the ocean.  The big picture: Monday’s unrelenting rainfall resulted in 101,433 cubic feet per second of water inflow into the Sacramento-San Joaquin Delta, according to data provided by the Bureau of Reclamation. The rainy first week of the year averaged around 85,000 cubic feet per second of water inflow. … ”  Read more from the San Joaquin Valley Sun here: Calif. flushed 95% of incoming Delta water to Pacific Ocean during Monday’s massive storm

Why can’t we store all the rainwater from the storms?

Why Guy is getting many questions about why we can’t store all the rainwater we’re getting. California is still officially in a drought and we need water for drinking and agriculture and other basic needs. Even though it’s been dumping rain like watery gold, we can’t seem to store it all.  We have reservoirs and dams that do much of the water storage, but most of the rain we’ve been getting is flowing into the Pacific Ocean. It’s wasted.   The rain is also falling so quickly that we can’t store it and what we want to do with it is get it out of here to clear our roadways and landscapes as soon as possible. …  “Now is the time to be banking this water as this storm series rolls through. Roseville is doing its part to build a reliable water system for customers and the Sacramento region,” said water expert Jim Peifer of the Regional Water Authority. … ”  Read more from Channel 10 here: Why can’t we store all the rainwater from the storms?

Heavy rain is still hitting California. A few reservoirs figured out how to capture more for drought

Despite several weeks of torrential rain and flooding, California is still facing a severe multi-year drought. That has many people thinking about how to better capture winter floodwaters to last through the dry season.  An innovative approach at two California reservoirs could help boost the state’s water supply, potentially marking a larger shift from decades-old water management approaches to a system that can quickly adapt to precipitation in a changing climate.  At issue are rules that, at face value, seem perplexing to many Californians. Even in a chronically dry state, reservoirs are not allowed to fill up in the winter. … ”  Read more from NPR here: Heavy rain is still hitting California.

Who’ll stop the rain? California’s got nowhere to put it

After several weeks of rain, Southern California remains under advisories for flooding, high winds, and high surf. Early this week, 90% of California was under a flood watch. L.A. County — which has received 2 to 6 inches of rain along the coast and in coastal valleys and about 8 inches in the mountains — could see an additional .5 to 1.5 inches, with more expected at higher elevations, meteorologists say. Here, Kurt Schwabe, the associate dean of the School of Public Policy and a professor of environmental economics and policy, addresses the infrastructure deficits this spate of rain had laid bare.  Q: Can the California stormwater drainage and flooding infrastructure handle this level of rainfall?  Schwabe: Based on what we’re seeing and observing in terms of the destruction these past few storms have created, it’s clear that our stormwater and flooding infrastructure is falling short of what we should expect given California is the seventh largest economy in the world.  But, the “losses” are significantly more than this when one considers how much of this water we are not storing or capturing to help refill aquifers and reservoirs. … ”  Read more from UC Riverside here: Who’ll stop the rain?

Atmospheric Rivers: What are they and how does NOAA study them?

You may have heard of atmospheric rivers in the news lately due to the intense rainfall and flooding along the U.S. West Coast. These naturally occurring air currents can bring both severe disruption and great benefit through the heavy rain and mountain snows that contribute to regional water supply. On average, about 30 to 50 percent of annual precipitation in the west coast states occurs in just a few atmospheric river events. NOAA studies atmospheric rivers to improve forecasting capabilities as well as to improve our understanding of atmospheric river impacts on communities and the physical environment.  Atmospheric rivers are long, concentrated regions in the atmosphere that transport moist air from the tropics to higher latitudes. The moist air, combined with high wind speeds, produce heavy rain and snow upon landfall, especially over mountainous terrain. These extreme precipitation events can lead to flash flooding, mudslides, and catastrophic damage to life and property. … ”  Read more from NOAA here: Atmospheric Rivers: What are they and how does NOAA study them?

What excess rain means for California’s burn scars

As atmospheric rivers continue to drench California, officials worry about the impact the rain will have on the state’s burn scars.  Wildfire dangers are not over once the fire is out. Atmospheric rivers that produce ample rain bring another risk, as burn scars from the enormous summer fires leave nearby communities at risk for sudden and deadly debris flows.  Burning trees and other vegetation release soil-sealing wax making the ground almost waterproof across a burn scar. ... ”  Read more from Yahoo News here: What excess rain means for California’s burn scars

Torrential rains wreaking havoc on California communities proving beneficial for state’s forests

California’s precious trees are receiving a much-needed reprieve from the extreme drought conditions they have been experiencing for several decades.  The same atmospheric river storm system that is bringing devastating flooding to communities all over California is providing relief to the state’s forests, according to experts.  Data released last week by the U.S. Drought Monitor shows that regions in California and Nevada that were previously in “exceptional drought” status the week before — the highest level of concern — have been alleviated as a result of the rounds of heavy rain that have been walloping the coast. The plethora of extra moisture is likely to stave off a mass die-off of trees in the West, Jim Randerson, a professor of earth system science at the University of California Irvine, told ABC News. ... ”  Continue reading at ABC News here: Torrential rains wreaking havoc on California communities proving beneficial for state’s forests

In extraordinary move, California mulls crackdown on Los Angeles’ water draws at Mono Lake

Even as a storms shower California with rain and snow, state water regulators announced this week that they’re revisiting their effort to protect Mono Lake from the ravages of drought, agreeing to review how much water the city of Los Angeles is taking from the basin and whether it’s too much. …  Almost three decades ago, one of the biggest environmental campaigns in U.S history succeeded in forcing Los Angeles to reduce the amount of water it pipes from the basin to faucets in Southern California. Still, state regulators have told The Chronicle that the 1994 reductions haven’t raised Mono Lake to the point it should be at, nor will the recent storms and a potentially very wet year.  The State Water Resources Control Board has scheduled a public workshop for Feb. 15 to reopen discussion of the problems at Mono Lake and water diversions by the Los Angeles Department of Water and Power. … ”  Read more from the San Francisco Chronicle here: In extraordinary move, California mulls crackdown on Los Angeles’ water draws at Mono Lake

Something fishy is happening inside the ears of Delta smelt

Conservationists have spent decades trying to prevent the extinction of the delta smelt, a tiny transparent fish that smells vaguely of cucumbers. The funky fish is native to California’s San Francisco estuary, a series of bays and river deltas covering more than 4,000 square kilometers between Sacramento and the Golden Gate Bridge. The delta smelt was once the most abundant fish in the estuary but is now approaching extinction, with few fish left in the wild. … In December 2021, researchers at the University of California, Davis, started to experimentally release hatchery-reared delta smelt into the wild. The California Department of Fish and Wildlife (CDFW), which oversees the project, hopes the experiment will boost numbers, giving people more time to address the root causes of the fish’s decline, which include pollution, invasive species, and habitat loss caused by dams and agriculture.  However, mere months into the project, fish ecologist Levi Lewis and laboratory technician Jonathan Huang, both then at the University of California, Davis, noticed something fishy about the hatchery-reared delta smelt that raises questions about the project’s effectiveness. … ”  Continue reading at Hakai Magazine here: Something fishy is happening inside the ears of Delta smelt

The pollution causing harmful algal blooms

It is the “smell of decay and death”, says Beth Stauffer, from the University of Louisiana. “It has a physical presence. This layer of very striking greens and blueish greens…when you put your paddle in it, you can feel it.” She’s describing the harmful algal blooms (HABs) that used to be more associated with marine environments. But in recent years they’ve been moving further inland and affecting freshwater systems, too. And scientists such as Stauffer are trying to find out why.  HABs occur when certain kinds of algae grow very quickly due to increased nutrients in the water – typically when artificial nitrogen and phosphorus applied to farmers’ fields wash out in the rain and enter waterways. The algae receive a meal on a scale they would never get naturally, and a bloom is formed. Sometimes this is harmless. But at scale, many types of algae can turn toxic and harmful to humans and animals. And this scale can be extraordinary. … ”  Read more from the BBC here: The pollution causing harmful algal blooms

From parched to flooded: Making sense of California’s weather whiplash

Columnist Marek Warszawski writes, “Water, water everywhere. So much it makes you think. Only two months ago our parched state was staring down the empty flask of another dry winter. Then December arrived with a splash, and since the calendar flipped California has been wringing in the new year. All this rain is a welcome sight, but please not all at once. Caused by the onslaught of atmospheric rivers — everybody’s favorite new meteorological term — thousands of homes have been evacuated while dozens of roads are closed by flooding and rockfalls. At least 14 people have died.  In times like this, it feels a little callous to gawk at rainfall totals and monitor reservoir levels while pondering big-picture questions (“Is California still in a drought?”) that can’t truly be answered till we see what February, March and April bring.

That number might be far lower had the state been adequately prepared to capture the gift from the sky.  California hasn’t built a new dam in four decades. An estimated more than 80 percent of the state’s winter rainwater is annually wasted.

Fremont Weir will flow for several days to help reduce flooding

The Fremont Weir near Sacramento is flowing once again in an effort to reduce flooding. California Department of Water Resources officials forecast the weir to flow for the next five days, as it is designed to do. Weirs are low dams designed to help manage floods. Weirs move water when it reaches a specific height into a flood bypass to relieve pressure on mainstream levees. Whenever water in Sacramento River exceeds the height of Fremont Weir, the excess flow runs into the lower Yolo Bypass floodway, reducing the risks of flooding Sacramento.”

Here’s what to know about weirs and how they’re used in Sacramento

If you’re driving north of downtown Sacramento on Highway 5 or 99, you may notice flooding in off-road areas that seem a little unusual. What you’re likely seeing is one of many weirs in the Sacramento region that help prevent flooding during intense weather. Since New Year’s Eve, many weirs in the area have diverted water that would have otherwise overflowed out of the American, Sacramento and Feather rivers, among others.  Unlike dams or levees, weirs aren’t created to store water or hold it back. Instead, weirs divert water. When a river begins to overflow, like it might during a storm with a lot of rain, a weir carries that excess water from the river elsewhere.  Aside from the Sacramento Weir, which has a gate, most weirs don’t require anyone to operate them, passively diverting flow only after water levels in a river rise enough to pass over the weir structure. … ”  Read more from Capital Public Radio here:  Here’s what to know about weirs and how they’re used in Sacramento

3 more atmospheric rivers headed for Sonoma County. What’s driving the storm train?

January is typically atmospheric river season in California, but since the start of the new year Sonoma County has been hammered by an almost nonstop series of them — an unusual occurrence, which experts are attributing to the jet stream that is surging over the Pacific Ocean.  Literally described as rivers in the sky, three more of these moisture-laden events are being carried by winds toward the Golden State, according to meteorologists, who expect more storms to begin Wednesday night.  While the presence of atmospheric rivers has barely raised alarms among weather forecasters, what has stood out is that they’re happening in such quick succession.  The Bay Area is usually hit by about a dozen atmospheric rivers during the winter, according to the National Weather Service’s Bay Area office in Monterey. But including the two that occurred after Christmas, the region — and Sonoma County in particular — have already been hit by at least six of them.  “If I had my wish, I would like to spread these out more,” Hecht said Tuesday. ... ”  Read more from the Santa Rosa Press Democrat here:  3 more atmospheric rivers headed for Sonoma County.

Two more storms are headed to the Bay Area — here’s when to expect the heaviest rain

After 16 days of relentless Pacific storms, including a bomb cyclone, and a constant stream of atmospheric rivers, most of the Bay Area is slated to see a comfortable break in the wet pattern Thursday.  This is thanks to a shift in the flow of air thousands of feet above the ground — the jet stream — its winds gradually shifting north in the coming days, meaning the storm door will finally begin to close. But before it does, two more storms will roll into far Northern California this weekend and into early next week.

Editorial: Heavy rain gives Marin Municipal Water District all the more reason to push for change

The Marin Independent Journal editorial board writes, “With its reservoirs nearly full and three newly elected directors, the Marin Municipal Water District has an enviable opportunity to plan ahead – to increase its storage capacity and expand use of recycled water – and be better prepared for the inevitable return of another drought.  Recent storms have been filling MMWD’s chain of mountain reservoirs, bolstering the district’s supply which only two years ago was perilously low.  As of Tuesday, all MMWD reservoirs were spilling at 100% and the stream of storms in this “atmospheric river” promised to dump more rain on the region.  The 2020 storms relieved worries that the storage levels in MMWD’s reservoirs were running low. … ”  Read more from the Marin Independent Journal here: Editorial: Heavy rain gives Marin Municipal Water District all the more reason to push for change

Reservoirs serving Berkeley, Oakland are filling up after consistent rain

The parade of storms that has drenched California over the past several weeks has gone a long way toward replenishing the reservoirs that provide Berkeley and Oakland with drinking water.  East Bay Municipal Utility District reservoirs, which serve 1.4 million customers in Alameda and Contra Costa counties, were filled to 84% of their capacity as of Tuesday, up from 68% in September, before the rainy season began.  The region’s biggest source of drinking water, the Pardee Reservoir east of Lodi, is 96% full, with more rain in the forecast over the next several days. And the Mokelumne River watershed that EBMUD draws from also has more water banked up in the Sierra Nevada snowpack, which state and utility data show is currently more than double its historical average. ... ”  Read more from Berkeleyside here: Reservoirs serving Berkeley, Oakland are filling up after consistent rain

Dam spillover not anticipated through week in San Mateo County

San Mateo County has announced it and the San Francisco Public Utilities Commission are not expecting dam spillover from Crystal Springs Reservoir due to flooding through at least Jan. 17.  However, major storms pose flooding risks, with the county urging residents along the creek to take precautions if their property has flooded in the past, according to a county press release. Significant rainfall from this series of storms is raising the levels of the Crystal Springs Reservoir and there remains a 25% risk of reservoir spill later in January. If a spill occurs, rainfall flowing into the reservoir would flow out in addition to rainfall downstream resulting in high levels in San Mateo Creek. … ”  Read more from the San Mateo Daily Journal here: Dam spillover not anticipated through week in San Mateo County

Residents of the Monterey peninsula may soon find themselves trapped — with no way in or out of the tourist destination as storms continue to batter Northern California, officials warned.  Monterey County Sheriff Tina Nieto said Wednesday that there’s a possibility that the peninsula — which includes the towns of Monterey, Pacific Grove, Pebble Beach and Carmel — could become an island due to flooding of roads leading in and out of the area.  “Unfortunately the ground is really saturated and everybody knows that and there’s no where for the water to go except for the rivers and our waterways,” Nieto said at a news conference. … ”  Read more from the San Francisco Chronicle here: Flooding may turn Monterey peninsula into an ‘island’ as water cuts off roads, sheriff warns

Winter storms wreak havoc — and also remind us nature is still in charge.

In modern, urban life, it can be easy to forget we have built many of our neighborhoods on top of waterways. Especially in California’s long dry seasons – coupled with a years-long drought – creeks and rivers can come to resemble ditches.  But they are always there, a landscape of rivers and creeks, waiting to gush with water when water is there. That humans have constructed bridges, roads and homes is irrelevant to powerful, surging water. And when years go by without a major winter storm, people can forget how fast and fierce moving water is, hence the relentless drumbeat of advisories from public officials in the past two weeks: Be ready, and heed evacuation warnings. … ”  Read more from Monterey Weekly here:  Winter storms wreak havoc — and also remind us nature is still in charge.

San Luis Obispo County reservoirs swell after rain storms. How much did water levels rise?

Recent storms have caused water levels at local reservoirs to swell dramatically after years of drought shriveled the important resources. One San Luis Obispo County lake was overflowing as of Wednesday, while another nearly doubled in capacity. “This is fantastic news,” said Shane Taylor, Arroyo Grande’s utilities manager. “This is just what we needed.”  An incredible amount of rain has fallen over San Luis Obispo County in December and January — which are typically some of the rainiest months of the year. ... ”  Read more from the San Luis Obispo Tribune here: San Luis Obispo County reservoirs swell after rain storms.

Rains pumping up Santa Barbara County reservoirs; Cachuma at 68% capacity

The major storm that battered Santa Barbara County on Monday set creeks and rivers flowing and pumped up reservoirs with runoff from ground already saturated after more than a week of rain. That influx of water will help alleviate the drought that has gripped the area for years, and more rain is on the way, although not in the volumes seen Monday, officials said during Tuesday’s Santa Barbara County Board of Supervisors meeting. County Fire Chief Mark Hartwig said Eric Boltz, meteorologist for the National Weather Service Office in Oxnard, told him the 6 inches that fell on the South Coast Monday and more than 12 inches on the mountain peaks set records. … ”  Read more from the Santa Maria Times here: Rains pumping up Santa Barbara County reservoirs; Cachuma at 68% capacity

‘Vitamins for the clouds.’ Santa Barbara County turns to cloud seeding to boost rainfall

Mother Nature can be fickle when it comes to delivering rainfall to Santa Barbara County, and sometimes she gets a technological nudge to deliver a bit more precipitation to help replenish local reservoirs. That’s done through a process known as “cloud seeding,” and accomplished under a program overseen by the Santa Barbara County Water Agency. “Any cloud seeding program is just enhancing rainfall,” Matt Scrudato, a senior hydrologist for the Water Agency, told Noozhawk. “It’s designed to make it rain more.” … ”  Read more from the Sacramento Bee here:  ‘Vitamins for the clouds.’ Santa Barbara County turns to cloud seeding to boost rainfall

‘The margins are so minimal:’ Ventura County farmers take stock of damage after latest storm

A crawdad unfurled from its hiding place, planting eight legs in the silty muck left behind by the floods, and brandished its pincers.  Displaced from the Santa Clara River several dozen yards away, the little warrior staunchly defended its new home: a 6-inch deep puddle of water around Anthony Bibian’s strawberry field near Ventura.  This week’s rainstorms blocked roads, flooded buildings and took out a train bridge in the hills ringing the county.  As the floodwaters poured through the Santa Clara watershed, they also overwhelmed the banks of the river, flooding fields along the river’s edge and wiping out crops and livestock operations. Damages could be in the millions of dollars. ... ”  Read more from the Ventura County Star here: ‘The margins are so minimal:’ Ventura County farmers take stock of damage after latest storm

California braces for fourth year of drought as groundwater drilling frenzy ensues

Despite historic rainfall to begin 2023, California is bracing for a fourth consecutive year of drought. People in the state have long bolstered the increasingly scarce water supply by pumping from an underground basis. But as KCBS meteorologist Evelyn Taft discovered on a trip to the San Joaquin Valley, people are overdrafting groundwater.

Madera farmers push back on tighter pumping restrictions, county agrees to keep status quo

Facing heated pushback from growers, Madera County officials decided to maintain current groundwater pumping allotments for the next two years rather than reduce allocations over that time.  At its Jan. 10 meeting, Board of Supervisors also considered increasing penalties for growers who exceed pumping allocations in the Madera, Chowchilla, and Delta-Mendota subbasins as part of an effort to raise money for projects geared toward bringing more water into the critically over drafted region.  Madera County has been the site of an escalating battle over how to reduce groundwater pumping and who should pay for new water projects. … ”  Read more from SJV Water here:  Madera farmers push back on tighter pumping restrictions, county agrees to keep status quo

Southern California gets storm reprieve but rain returning this weekend

With the recent, massive storm moving on, Southern Californians can expect days of sunshine — even as some residents continue to clean up and dig out from the mud.  That reprieve will be brief:  The National Weather Service says the region will likely see some rain on Saturday and Sunday and then a repeat of the storm on Monday and Tuesday. With that heavier rain, residents can expect more dangerous flooding and mudflows.  “People should just be aware that potentially hazardous weather is coming again,” said Casey Oswant, a meteorologist for the National Weather Service. “When there’s rain, there’s always potential for flooding — it’s just a matter of how widespread it will be.” … ”  Read more from the OC Register here: Southern California gets storm reprieve but rain returning this weekend

Metropolitan advances project to deliver new water supplies to communities hit hardest by drought

Construction will begin soon on the first of several projects to bring additional water to Southern California communities hit hardest by the state’s record drought, following a vote by Metropolitan Water District’s Board of Directors this week to award a contract for the project’s construction.  The suite of projects will reengineer Metropolitan’s water delivery system to help bring much-needed water from Metropolitan’s Diamond Valley Lake – the largest reservoir in Southern California – to parts of eastern Los Angeles County and western San Bernardino County that have been under unprecedented mandatory conservation measures since last June because of limited access to water supplies.  Southern California imports about half of the water used in the region from the Northern Sierra, through the State Water Project, and the Colorado River. But because of infrastructure limitations, some communities – home to more than 6 million people – are heavily dependent on State Water Project supplies. And when the drought slashed these supplies, they were required to dramatically reduce their use. … ”  Read more from Business Wire here: Metropolitan advances project to deliver new water supplies to communities hit hardest by drought

California storms boosting OC’s water supply past capacity to capture all that rain

California’s recent storms have provided a big boost to Orange County’s water supply, with so much rain falling that it’s exceeding the county’s ability to capture all of it.  With a forecast of more rain coming this weekend, some of the captured water will actually have to be released briefly into the Pacific Ocean, county officials say.  The storms are keeping the Orange County Water District busy, as the agency collects rain water to help supply northern and central OC.  Most of the rain that has made its way into the Santa Ana River since this past November will be put to use, according to Greg Woodside, executive director of planning and natural resources at the OCWD. ... ”  Read more from KABC here: California storms boosting OC’s water supply past capacity to capture all that rain

Beaches battered by storms and surge, but spared major damage

With a break in the storms, crews are cleaning up the mess left behind following the recent big surf and heavy rains that battered the region in the past week.  The north end of Bolsa Chica State Beach’s parking lots, closed for nearly a week following a flooding of seawater that stretched across the sand and into Pacific Coast Highway, will reopen by Thursday, Jan. 11, following extensive clean-up efforts, said State Parks Superintendent Kevin Pearsall.  Crews worked 17-hour shifts in recent days to remove debris and sand, he said, from the lots and the multi-use trail after the rain storm that hit last Thursday mixed with extreme high tides and a hefty swell to overwhelm the shore.  “It’s insane the amount of trash and debris and driftwood,” Pearsall said. “We’re asking people to be cautious and courteous of the cleanup process and so far everyone has complied.” ... ”  Read more from the OC Register here: Beaches battered by storms and surge, but spared major damage

Water leaders to lawmakers: No ‘silver bullet’ in Arizona’s water crisis

The day after Gov. Katie Hobbs delivered her first State of the State, outlining plans to address the state’s growing water crisis, the heads of the state’s water agencies stood before lawmakers to deliver an at times grim reality of the state’s water future.   “I do not believe that any of the (Active Management Areas) are at a safe-yield,” Tom Buschatzke, director of the Arizona Department of Water Resources, told the House Natural Resources, Energy and Water Committee on Jan. 10.  Active Management Areas, generally referred to as AMAs, were created in 1980 in an effort to help the state manage its groundwater resources as the state continued to grow. Only the AMA in Tucson is near a safe-yield, meaning the amount of water withdrawn is balanced with the amount recharging it, but Buschatzke said that Tucson has reached that by storing large amounts of Colorado River water delivered by Central Arizona Project. … ”  Read more from the Arizona Mirror here: Water leaders to lawmakers: No ‘silver bullet’ in Arizona’s water crisis

Arizona says developers lack groundwater for big growth dreams in the desert west of Phoenix

A newly released state report on groundwater supplies under the desert west of Phoenix signals difficulty ahead for developers wishing to build hundreds of thousands of homes there.  It also signals the start of an effort by Arizona’s new governor to shore up groundwater management statewide.  Gov. Katie Hobbs released the modeling report Monday afternoon, and it shows that plans to add homes for more than 800,000 people west of the White Tank Mountains will require other water sources if they are to go forward.  The Arizona Department of Water Resources had developed the model showing inadequate water for much of the development envisioned as far-west suburbs, but had not released it during then-Gov. Doug Ducey’s term. … ”  Read more from Arizona Central here: Arizona says developers lack groundwater for big growth dreams in the desert west of Phoenix
