Storms to deliver rain, mountain snow across western US through Christmas

Residents across the western United States who have drought relief on their holiday wish lists this season will be in luck over the next week. A series of storms will take aim at the West Coast and deliver needed rain and mountain snow from Southern California to the Pacific Northwest through Christmas Day. …”For the start of the holiday week, rain could arrive in San Francisco on Monday and delay holiday travelers or even just those going holiday shopping,” said Storm.  Southern California has turned drier following this past Tuesday’s deluge, but that dry spell will come to an end for parts of the region next week. “By Tuesday, rain or showers could reach as far south as places like Santa Barbara, California,” said Storm. … ”  Read more from AccuWeather here: Storms to deliver rain, mountain snow across western US through Christmas

Atmospheric river is a win for California: Snowpack goes from 19% to 83% of average

The drought is far from over in California, but this week’s atmospheric river may have begun to put a small dent in the state’s worrisome water deficit.  While a prior October atmospheric event earlier in the year brought historic rainfall totals to Northern California, this most recent storm delivered drenching rains to both the north and the south and blasted the Sierra Nevada with snow. Locations across the state reported impressive storm totals, from 11 inches of rain atop Mount Tamalpais in Marin County, to over 60 inches of snow at the UC Berkeley Central Sierra Snow Lab in Soda Springs, to 8.18 inches at San Marcos Pass in Santa Barbara County. ... ”  Read more from SF Gate here: Atmospheric river is a win for California: Snowpack goes from 19% to 83% of average

State water regulators tap possible new reservoir

As California’s severe drought lingers on, water regulators have voted to advance what could be the state’s first major new water storage project in decades, but tribal and environmental groups are voicing opposition.  Proponents say it is needed to supply more water to homes and agriculture.  Opposition groups claim the new Sites Reservoir in Colusa County would accelerate the extinction of multiple species of salmon because water would have to be pumped from the nearby Sacramento River. Sites reservoir is one of seven water projects set to receive funding from a voter-approved bond in 2014. Most of that money is targeted towards expanding existing reservoirs or building water recycling programs. … ”  Read more from My Mother Lode here: State water regulators tap possible new reservoir

Tribal representatives express concerns over Sites Reservoir

The Sites Project Authority received criticism Thursday as it conducted a public hearing and presentation on the history and variations of the Sites Reservoir project planned for Colusa County.  Environmental Planning Commissioner Ali Forsythe led the online meeting with a presentation on the project, how it came to be and what changes have been made over the years it has been in the works.  A half-hour was slotted for questions immediately after the presentation followed by an hour of public comment. A court reporter attended the zoom meeting to keep track of the comments in an official format. Once public questions and input began, almost all of the speakers shared criticism for the project with many asking that the group not go forward with the project in any capacity. … ”  Read more from the Chico Enterprise-Record here: Tribal representatives express concerns over Sites Reservoir

State finalizes groundwater management principles and strategies addressing drought impacts on drinking water wells

The Department of Water Resources and the State Water Resources Control Board today issued final groundwater management principles and strategies to help protect drinking water wells from the  impacts of drought.  Developed in response to Governor Gavin Newsom’s drought state of emergency proclamation in April, the principles and strategies provide a framework for state actions to proactively address impacts on groundwater-dependent communities as droughts become more frequent and intense as a result of climate change.  These principles and strategies incorporate hundreds of public comments received earlier this fall, including written comments submitted to DWR and feedback at public workshops and webinars. … ”  Read more from DWR here: State finalizes groundwater management principles and strategies addressing drought impacts on drinking water wells 

CA Department of Water Resources warns 27 GSAs over risks to well users

On December 9 the Department of Water Resources (DWR) took another important step toward protecting drinking water supplies by issuing correspondence letters to 27 Groundwater Sustainability Agencies (GSAs), warning GSAs that these plans will be deemed incomplete when final assessments are issued at the end of January.  These GSAs span across the San Joaquin Valley, including Kern Groundwater Authority, Kern River, Buena Vista Water Storage District, Olcese Water District, Henry Miller Water District, Tri-County Water Authority, Lower Tule River Irrigation District, Alpaugh, Delano-Earlimart Irrigation District, Eastern Tule, Pixley Irrigation District, Tulare Lake, Mid Kaweah, Greater Kaweah, East Kaweah, James, Central Kings, North Fork Kings, South Kings, McMullin Area, Kings River East and North Kings.  DWR cited previously issued consultation letters that identified a lack of information and required justification of sustainability goals that would jeopardize the water supplies of thousands of Californians. ... ”  Read more from the Valley Voice here: CA Department of Water Resources warns 27 GSAs over risks to well users

Tunnel advisory group comes to an end

The work of a stakeholder committee created to provide input on the design of the Delta Conveyance Project (DCP) tunnel came to an end as its last official meeting was conducted earlier this month. The Delta Conveyance Design and Construction Authority (DCA), the agency responsible for the design, construction and financing of the single-tunnel project, approved the creation of the Stakeholder Engagement Committee (SEC) in October 2019. The SEC’s role was to offer feedback on the tunnel’s design and identify the impact of DCA activity on the people who live, work and recreate in the Delta region. ... ”  Read more from the Brentwood Press here: Tunnel advisory group comes to an end

California reservoir levels still measuring low after the rainfall

While the last rainstorm was good news for California’s water storage, the state is not out of the drought yet.  Lexington Reservoir in Los Gatos rose 10 feet after the last storm, but it is still less than 30% capacity. Reservoirs across the state are also measuring well below average.  “This is what we refer to as a beneficial storm, where it’s helping deal with the drought conditions obviously and then most importantly promote regrowth, especially in and around our burn scars,” said Paul Lowenthal, Santa Rosa Fire Marshall. ... ”  Read more from KTVU here: California reservoir levels still measuring low after the rainfall

California farming by the numbers: water edition

As the year comes to an end, California farmers carried their way through the pandemic, market disruptions, drought, wildfires and more. California Farm Bureau‘s annual By The Numbers report showed producers persevered and kept farming, especially when it came to water challenges.  Based on 2021, implications from a dry water year with water shortages and cut-offs are expected to have an economic impact of more the $2.5 billion dollars. There were 4,550 Central Valley farms that were cut off from surface water allocations from the Sacramento/ San Joaquin Delta due to the State Water Resource Control Board curtailment orders with more than 10,300 water rights members effected in some way. ... ”  Read more from Ag Net West here: California farming by the numbers: water edition

Listen: The species we save

Humans have long tried to mitigate their own destructive impact on the planet through conservation efforts. Often, those efforts are attached to one iconic species or another — the majestic bald eagle, cuddly cute baby seal, or awe-inspiring blue whale. But is this about them, or is it about us? On this episode, we take a closer look at conservation, and dig into the human motivations and emotions behind it.  We hear stories about a near-extinct fish called the delta smelt — and whether it’s actually worth saving; how a weird-looking bird has sparked a battle over land in the American West; and how plucky raccoons carve out their own existence in cities.”  Listen to the radio show at WHYY (48:48): The species we save

Snow drought current conditions and impacts in the West

Autumn 2021 ended with a warm and dry November for much of the West, leaving little snowpack in the mountains to start the climatological winter in December. While a shift to more stormy and colder weather increased snowpack in some areas like the Sierra Nevada, snow water equivalent (SWE) is at record low values in New Mexico, Colorado, Utah, Montana, Wyoming, and Nevada.  Warm snow drought conditions have developed in parts of the Washington Cascades, northern Oregon Cascades, and eastern Oregon. … ”  Continue reading at NIDIS here: Snow drought current conditions and impacts in the West 

Why water affordability? Why now?

Everyone needs water, but many Americans are struggling to pay the rising costs of water services. The COVID-19 pandemic is amplifying existing water affordability and equity challenges throughout the US. As widespread unemployment and shutdowns disrupted Americans’ lives water affordability became an urgent public health issue and the focus of many national policy discussions. In California, 1 in 8 households had water debt as of January 2021.1 That’s at least 1.6 million households across the state of California. Utilities generate the revenue they need to pay for operations, maintenance, and infrastructure from their customers – including households. When households cannot pay their bills, the utility experiences financial distress as well. In California, water systems are absorbing an estimated $1 billion of unpaid household bills.2 This same story is playing out for water systems across the nation, highlighting the integral link between the financial health of a utility and the financial health of their customers. … ”  Continue reading from the Internet of Water here: Why water affordability?

Atmospheric rivers spur high-tide floods on U.S. West coast

Atmospheric rivers are narrow bands of moisture that travel across the lower troposphere, generally at the leading edges of massive low-pressure systems. At their peak, they can carry as much water through the sky as the Amazon River does on land. They unleash intense winds and heavy rain as they surge across the Pacific Ocean, eventually making landfall on the U.S. West Coast, contributing to many high-tide flooding events. However, the detailed relationship between atmospheric rivers and coastal high-tide flooding has not been well described.  In new research that will be presented on 17 December at AGU’s Fall Meeting 2021, scientists revealed how atmospheric rivers affected many high-tide flooding events on the U.S. Pacific coast over the past 4 decades. … ”  Read more from EOS here: Atmospheric rivers spur high-tide floods on U.S. West coast 

California burning: Stanford research looks at drought, wildfires, and smoke and the growing risks of climate change in the Golden State

In July 2021, smoke from California’s Dixie Fire, the second largest in the state’s history, combined with smoke from fires in the American West and Canada, traveled thousands of miles to New York and other parts of the East Coast, triggering air-quality alerts. It was an alarming message for people a continent away from the flames that the environmental fallout from climate change does not respect state lines.  California is prone to both droughts and floods, but climate change is sending those natural cycles into overdrive. In the last decade, record-breaking heat waves have combined with severe and prolonged droughts to disastrous effect. Eight of the state’s top 10 largest wildfires took place in the past five years, exacting a huge personal and financial toll on people, homes, farms, and tourism.  For Stanford Law faculty, students, and alumni who study water, wildfire, and smoke, California is already at a crisis point, giving their research new urgency. ... ”  Read more from Stanford Lawyer here: California burning: Stanford research looks at drought, wildfires, and smoke and the growing risks of climate change in the Golden State

No relief from rain: Climate change fuels compound disasters

Early on 9 January 2018, slabs of the Santa Ynez Mountains hurtled down into the community of Montecito, Calif. More than a centimeter (half an inch) of rain had fallen in 5 minutes over the burn scar of the Thomas Fire, which had been raging for more than a month and had yet to be fully contained. Mudslides that morning killed 23 people and caused millions of dollars in damage.  As climate change upends temperature and precipitation patterns across the western United States, communities can expect to see more of these compound fire-rain disasters, according to new research that will be presented on 17 December at AGU’s Fall Meeting 2021. … ”  Read more from EOS here: No relief from rain: Climate change fuels compound disasters 

The great danger of the tiny bark beetle

As he drove through the Sierra Nevada in 2019, Zachary Robbins noticed all the dead trees. Most of them had probably died around 2016 thanks to a combination of California’s drought and its growing population of bark beetles—tiny creatures that kill giant trees. Although workers had tried to salvage whatever they could for commercial timber, Robbins, a researcher in the Dynamic Ecosystems and Landscapes Lab at North Carolina State University, was astounded by how many withered pines still dotted the forest.  Of the some 600 species of bark beetles, the western pine beetle is prevalent in this region. They chew away at bark and live within the phloem of ponderosa pines, the living tissue that transports nutrients. The infestation creates bark beetle “galleries” that look like long-legged centipedes living within the tree; these can kill the host by cutting off nutrient flow. Dead trees can present a perilous situation to nearby residents because they create more flammable material for wildfires. … ”  Read more from Wired Magazine here: The great danger of the tiny bark beetle

We can’t rely on drought-busting atmospheric rivers anymore

Katerina R. Gonzales, a climate scientist who bridges the gap between climate research and practice, writes, “Rather than telling the seasons by temperature fluctuations, Bay Area locals can tell the seasons by the hue of the hills. Are the hills brown? Green? A mixture of the two? This past summer they appeared to be darker brown than the previous summers we’ve had—the light blonde color of the grasses gradually yielding to orange-brown, and dark brown as we’ve gone deeper and deeper into this dry season—the landscape almost mirroring the colors of fire season, flashing orange and black in mourning and solidarity with the thousands of acres burning across the region.  One of my favorite things about the Northern California rainy season is to notice how green the hills get after only a couple storms. Seeing the arid hills turn into lushness in a matter of weeks. Seeing before-and-after imagery illustrating that the Sierra’s snowpack was re-charged.  While we can see sprinkles here and there from smaller storms, the source of major winter storms is almost always atmospheric rivers. … ”  Read more from Bay Nature here: We can’t rely on drought-busting atmospheric rivers anymore

Do right by California’s tribes through the 30×30 conservation effort

Morning Star Gali, a member of the Ajumawi band of the Pit River Tribe and  serves as the Tribal Water Organizer for the Save California Salmon, and Kate Poole, a senior director on the nature team at Natural Resources Defense Council, write, “Designated months that recognize Native American Heritage and governor-appointed advisory councils are opportunities for Californians to reflect on the history of Indigenous peoples in our state, but they are not sufficient for us to redress the historic wrongs suffered by California’s tribes.  In 1851, the state’s first governor declared “a war of extermination will continue to be waged between races, until the Indian race becomes extinct.” Many California Indians survived the genocide of colonial settlement in California but have nonetheless been deprived of their traditional way of life by being dispossessed of their lands and culture. Californians now have an opportunity to begin to repair these historic wrongs through Gov. Gavin Newsom’s initiative known as 30×30. … ”  Read more from Cal Matters here: Do right by California’s tribes through the 30×30 conservation effort

Did California issue its last fracking permit? Let’s hope so

The Los Angeles Times editorial board writes, “There’s been a welcome development in California’s fight against climate change: Regulators are saying no to the oil industry.  Earlier this year, state oil and gas regulators quietly began denying hydraulic fracturing permits on climate change grounds, without waiting to finish regulations to ban fracking by 2024 that Gov. Gavin Newsom has ordered. Since July, the state Geologic Energy Management Division has denied 109 permits sought by oil companies to use hydraulic fracturing or other well stimulation methods, and in 50 of those cases has cited the impacts on the climate and public health.  California has not granted a fracking permit since February. So if the streak of denials continues, it’s possible that will be the last one ever issued. ... ”  Read more from the LA Times here: Did California issue its last fracking permit? Let’s hope so

Salt River restoration on hold for 5-10 years due to land, grant funding issues

At Ferndale’s City Council meeting on Wednesday, the council heard an update regarding the Salt River Restoration Project, which due to land disputes is now paused.  The project, which has cost roughly $35 million to date, mostly from state and federal grants, aims to restore wildlife, decrease flooding and improve agricultural benefits along seven miles of the Salt River and 330 acres of tidal marsh. The areas the project has completed construction on will continue to have maintenance performed on them, but will not expand in the coming years. The project is estimated to be on hold for five to 10 years because the Humboldt County Resource Conservation District’s grant funds to pursue the project will close before the district estimates a deal can be reached with local landowners dotting the final 1.2 mile stretch of the river. … ”  Read more from the Eureka Times-Standard here: Salt River restoration on hold for 5-10 years due to land, grant funding issues

How wet is your winter? Water and drought in Sonoma County

Jonah Raskin, Professor at Sonoma State University,  writes, “Bob Dylan was spot-on when he sang, “You don’t need a weatherman to know which way the wind blows.” He was also spot-on when he sang, “A hard rain’s gonna fall,” though hard rains don’t fall as often as they once did in the hills and valleys of Sonoma County where drought has become the new normal. Huge weather events— once referred to as “Pineapple Expresses” and now usually described as “Atmospheric Rivers”—have been around for a while, but they seem to take place more frequently now than in the past. The data isn’t conclusive. Still, an atmospheric river can occur during a year of intense drought. Not long ago, the Russian River flooded during a season of below average precipitation.

Marin commentary: Water district must create new sources, stop living ‘paycheck to paycheck’

Kristi Denton Cohen, an independent filmmaker, writes, “Frequent droughts, wildfires and limited water supply are becoming increasingly dire throughout the state.  Since the gangbuster drought in 1976-77, there have been multiyear droughts from 1986-1992, 1999-2004, 2006-2010, 2011-2017 and, of course, the one we’re in now.  Our precious reservoirs on Mount Tamalpais are lined up like pins in a bowling alley.

How much snowpack in the Colorado River Basin comes from atmospheric rivers?

Atmospheric rivers, commonly defined as long, narrow corridors in the atmosphere, much like rivers in the sky, transport moisture from the tropics. These “rivers” can produce large amounts of snow accumulation when they make landfall during the cold season. With over half of the streamflow in the Colorado River originating from water released by snow melt, it’s important to understand how atmospheric rivers can affect snowpack in the region.  In a new Geophysical Research Letter article, authors Mu Xiao, and Dennis P. Lettenmaier, identify the atmospheric rivers in the Upper Colorado River basin during a 65-year-long historical record and evaluate their contribution to mountain snowpack. It was found that almost one-third of the snowpack in the basin is attributed to atmospheric river induced snowfall. The primary origin of these atmospheric rivers are from the southwest, however, the pathways do not affect the amount of snow they yield. … ”  Read more from the Climate Program Office here: How much snowpack in the Colorado River Basin comes from atmospheric rivers?
