The farms that create the economic engine of Pajaro Valley operate at different scales. Some growers are small, while others have labels you might recognize from the grocery store: Martinellis, Driscolls, California Giant, to name a few. Regardless of the amount of acreage under management, one thing that the farmers share is that most of their water comes from the ground. How to best handle the areaâs diminishing supply of groundwater has occupied local water managers for decades.

Entrainment at the South Delta pumps of the State Water Project and the Central Valley Project has been a concern for years, but disentangling its impact on the dwindling smelt population from those of other environmental and water management factors isnât easy, and operational differences between the SWP and CVP facilities complicate analysis. Now, US Fish and Wildlife Service statistician Will Smith has developed computer models for entrainment effects on different smelt life stages, part of a larger Delta Smelt Life Cycle project being rolled out this month; his model of adult smelt entrainment was published in the December issue of San Francisco Estuary and Watershed Science (a separate model for postlarval smelt will appear in another journal). âAdults exhibit...

The California Water Plan Update 2018âreleased by the Department of Water Resources in Julyâis meant to guide state policy and investment over the next 50 years to maximize the benefits squeezed out of every drop of the water supply. The timing of Update 2018 is fortuitous: In April, Governor Newsom ordered the California Natural Resources Agency, California Environmental Protection Agency, and California Department of Food and Agriculture to develop a portfolio of water resilience strategies.

Environmental issues were important to Michael Montgomery as a young man. Montgomeryâs career path led to 33 years with the United States Environmental Protection Agency, where he gained a wealth of experience in navigating complex regulatory landscapes to protect water resources, and ultimately to the San Francisco Bay Regional Water Quality Control Board, where he is now executive officer.

âFor so long in the water space youâve had these false dichotomies where you are being told you have to choose one or the other,â says Esquivel, who Governor Gavin Newsom appointed Chair of the State Water Resources Control Board in February. âThese narratives can fuel themselves, they take root in communities, but they donât really do much to get to the heart of the policy question.â A native of the Coachella Valley, Esquivel served on the State Board for two years prior to his appointment. He cites literature as a particular passion, and had planned on a career in academia before a college internship in former Senator Barbara Boxerâs Washington, D.C. office turned into a full-time job. âWhat I...

The winter kicked off with the State Water Resources Control Boardâs December vote to adopt increased flow objectives for the southern Delta. The vote provoked an immediate volley of lawsuits, both from water users and from environmental organizations. âGovernor Newsom has staked out turf against the Trump Administration,â says San Francisco Baykeeperâs Jon Rosenfield...

A fall flight over the Mexican coast where the Colorado River meets the Sea of Cortez offered me a gut-punching, eye-screwing, visual on the results of impaired flow. The semantics of âunimpairedâ and âimpairedâ flow have laced the language of California water management debates since some engineer invented these politically âneutralâ terms long ago. The terms refer to our alteration of freshwater flows from snowmelt and runoff by dams and diversions. But whatever the labels, or whichever estuary youâre referring to, keeping these flows from reaching the sea via rivers can starve these aquatic ecosystems of their liquid life force. Whether itâs the vast yellowing salt flats that are all that remain of the mighty marshes of the pre-dam Colorado...

A boatload of estuary experts from around the country gathered on an early October day to tour the prettiest part of San Francisco Bay. They paid rather less attention to Alcatraz and the Golden Gate than to each other. In town for the National Estuary Programâs annual Tech Transfer Conference, they had come to compare notes and strategies from the 28 varied bays, bights, bayous, and river mouths that benefit from one of the nationâs most durable, and efficient, environmental laws. In 1987 amendments to the Clean Water Act, Congress proclaimed selected tidewater regions to be âestuaries of national significanceâ and offered money to help local coalitions take on environmental problems there. Through all the political gyrations since, a thin...

Spring and summer 2018 saw frenzied activity around California WaterFix, the latest iteration of a decades-long, on-again-of-again effort to convey fresh water from the Sacramento River to the South Delta while bypassing the Delta itself. Governor Jerry Brown has made WaterFix a top priority, but the project â including twin tunnels comprising the largest infrastructure project in state history â still faces a raft of uncertainties.

âStormwater has traditionally been considered a nuisance or danger in terms of flooding and water quality,â says the Pacific Institute’s Morgan Shimabuku, lead author of Stormwater Capture in California: Innovative Policies and Funding Opportunities, âBut weâre starting to see it as more of a resource with potential for water supply.â Shimabuku notes that stormwater capture is also âa great strategy for adapting to climate change, alleviating the impact of high-intensity rainstorms and reducing dependence on other water sources in times of drought.â The report describes innovations in stormwater management in the Bay Area and beyond, including recent San Francisco ordinances that require builders of projects with large impervious surfaces to install and maintain stormwater capture infrastructure; projects larger than 250,000...

When Carl Morrison died in a crash of his small plane near Petaluma this past April, the press noted the loss of a family man, Civil Air Patrol commander, Marine Corps Veteran, and pious Mormon. The shock also reverberated through the world of Bay Area flood control and water agencies, for whom Morrison was indispensable. As his Bay Area business expanded, Morrison eased his commute by training as a pilot and acquiring a small plane. People marveled at how many places he seemed to be. âThere must have been more than one of him,â says Napa Countyâs Rick Thomasser. A man of formal habits, Morrison never dressed down for field-work. His peers might smile at that, but they cherished his...

Many communities in rural, unincorporated San Joaquin Valley are served by water systems high in nitrates and arsenic, or private wells not subject to inspection. But according to a new UC Davis study, about 99,000 valley residents live near public systems with clean water and could access it if service extensions, piping and other infrastructure improvements were implemented. Pending state legislation would create a fund for such projects through fees imposed on water districts. While the bill faces opposition from water agencies, it is supported by groups typically at odds, including environmental advocates and farmers. âThis is a problem generations in the making, and we need long-term solutions,â says Jonathan London of UC Davisâ Center for Regional Change and lead...

As climate change threatens to upend precipitation patterns and disrupt water supplies, agencies are increasingly searching for ways to wring more benefits out of every drop. Valley Water (Santa Clara) is seeking to take integrated water management planning to the next level through its One Water initiative. âThe idea is to manage all water â treated water, groundwater, stormwater, flood water, water for habitat, species and Baylands â as one resource,â says the Districtâs Brian Mendenhall.

When fire strikes upper watersheds like it did last October, responses can vary widely depending on land use and ownership. âWe view wildfire as a natural process,â says Cyndy Shafer of California State Parks. Wildlands and backcountry areas have largely been left alone, but itâs a different story when lands are managed not for ecosystems but for drinking-water quality. âYou want to minimize the erosion that occurs on site,â says Scott Hill of the East Bay Municipal Utility District, âwe donât want sediment in our storage reservoirs.â Whatâs best must be considered on a case-by-case basis.

Cold water, essential for the life cycle of Chinook salmon, is all too often in short supply along the Sacramento River. Two clever innovations have been implemented to conserve cold water into the autumn. First: A 300 foot tall, 250 foot wide âadjustable strawâ possessing a series of intake gates enables power plant operators to draw water from behind the dam at three different depths. Second: A 40 foot tall rubber sheet.

The Delta Stewardship Council was created in 2009 but given no say over a pending dual tunnels plan. The state was pushing a grand program called the Bay-Delta Conservation Plan. However, the BDCP was abandoned in 2015 in favor of two new, independent programs: EcoRestore and California WaterFix (popularly known as the twin tunnels). Rather than adopt a new policy on conveyance, the council has simply framed its discussion of the tunnels as another recommendation.

Motivated by the recent drought, local water agencies have formed an unprecedented partnership aimed at reducing the impact of future dry spells. The Bay Area Regional Reliability partnership consists of eight of the regionâs larger water districts. âFor the first time in the history of water deliver in the Bay Area, the water utilities are talking about how to assist each other when there is a shortage.â

On average, underground water distribution pipes can last about 100 years. EBMUD owns and maintains roughly 4,200 miles of them. And it replaces about ten miles per year. At that rate it would take four centuries to replace the whole system: an approach one could charitably call unsustainable even if all the pipes were brand-new today.

After four of Californiaâs driest years on record, our âwetâ season was so dry that state water officials panicked.Major reservoirs were drawn way down, and record-low snowpack would limit replenishment to a trickle. Water managers worried about the hot, dry months. Would reservoirs still hold enough for freshwater releases to keep saltwater from pushing deep into the Sacramento-San Joaquin Delta? So they built a barrier to block salt instead.

Nothing could be stranger than sitting in the dark with thousands of suits and heels, watching a parade of promises to decarbonize from companies and countries large and small, reeling from the beauties of big screen rainforests and indigenous necklaces, and getting all choked up.
It was day two of the September 2018 Global Climate Action Summit in San Francisco when I felt it.
At first I wondered if I was simply starstruck. Most of us labor away trying to fix one small corner of the planet or another without seeing the likes of Harrison Ford, Al Gore, Michael Bloomberg, Van Jones, Jerry Brown â or the ministers or mayors of dozens of cities and countries â in person, on stage and at times angry enough to spit. And between these luminaries a steady stream of CEOs, corporate sustainability officers, and pension fund managers promising percentages of renewables and profits in their portfolios dedicated to the climate cause by 2020-2050.
I tried to give every speaker my full attention: the young man of Vuntut Gwichin heritage from the edge of the Yukonâs Arctic National Wildlife Refuge who pleaded with us not to enter his sacred lands with our drills and dependencies; all the women â swathed in bright patterns and head-scarfs â who kept punching their hearts. âMy uncle in Uganda would take 129 years to emit the same amount of carbon as an American would in one year,â said Oxfamâs Winnie Byanyima.
âOur janitors are shutting off the lights you leave on,â said Aida Cardenas, speaking about the frontline workers she trains, mostly immigrants, who are excited to be part of climate change solutions in their new country.
The men on the stage, strutting about in feathers and pinstripes, spoke of hopes and dreams, money and power. âThe notion that you can either do good or do well is a myth we have to collectively bust,â said New Jersey Governor Phil Murphy whose state is investing heavily in offshore wind farms.
âClimate change isnât just about risks, itâs about opportunities,â said Blackrock sustainable investment manager Brian Deese.
But it wasnât all these fine speeches that started the butterflies. Halfway through the second day of testimonials, it was a slight white-haired woman wrapped in an azure pashmina that pricked my tears. One minute she was on the silver screen with Alec Baldwin and the next she taking a seat on stage. She talked about trees. How trees can solve 30% of our carbon reduction problem. How we have to stop whacking them back in the Amazon and start planting them everywhere else. I couldnât help thinking of Dr. Seuss and his truffala trees. Jane Goodall, over 80, is as fierce as my Lorax. Or my daughterâs Avatar.
Analyzing my take home feeling from the event I realized it wasnât the usual fear â killer storms, tidal waves, no food for my kids to eat on a half-baked planet â nor a newfound sense of hope â Iâve always thought nature will get along just fine without us. What I felt was relief. People were actually doing something. Doing a lot. And there was so much more we could do.
As we all pumped fists in the dark, as the presentations went on and on and on because so many people and businesses and countries wanted to STEP UP, I realized how swayed I had let myself be by the doomsday news mill.
âWe must be like the river, â said a boy from Bangladesh named Risalat Khan, who had noticed our Sierra watersheds from the plane. âWe must cut through the mountain of obstacles. Letâs be the river!â
Or as Harrison Ford less poetically put it: âLetâs turn off our phones and roll up our sleeves and kick this monsterâs ass.â
4th California Climate Change Assessment Blues
by Isaac Pearlman
Since Californiaâs last state-led climate change assessment in 2012, the Golden State has experienced a litany of natural disasters. This includes four years of severe drought from 2012 to 2016, an almost non-existent Sierra Nevada snowpack in 2014-2015 costing $2.1 billion in economic losses, widespread Bay Area flooding from winter 2017 storms, and extremely large and damaging wildfires culminating with this yearâs Mendocino Complex fire achieving the dubious distinction of the largest in state history. Californiaâs most recent climate assessment, released August 27th, predicts that for the state and the Bay Area, we can expect even more in the future.
The California state government first began assessing climate impacts formally in 2006, due to an executive order by Governor Schwarzenegger. Californiaâs latest iteration and its fourth overall, includes a dizzying array of 44 technical reports; three topical studies on climate justice, tribal and indigenous communities, and the coast and ocean; as well as nine region-specific analyses.
The results are alarming for our stateâs future: an estimated four to five feet of sea level rise and loss of one to two-thirds of Southern California beaches by 2100, a 50 percent increase in wildfires over 25,000 acres, stronger and longer heat waves, and infrastructure like airports, wastewater treatment plants, rail and roadways increasingly likely to suffer flooding.
For the first time, Californiaâs latest assessment dives into climate consequences on a regional level. Academics representing nine California regions spearheaded research and summarized the best available science on the variable heat, rain, flooding and extreme event consequences for their areas. For example, the highest local rate of sea level rise in the state is at the rapidly subsiding Humboldt Bay. In San Diego county, the most biodiverse in all of California, preserving its many fragile and endangered species is an urgent priority. Francesca Hopkins from UC Riverside found that the highest rate of childhood asthma in the state isnât an urban smog-filled city but in the Imperial Valley, where toxic dust from Salton Sea disaster chokes communities â and will only become worse as higher temperatures and less water due to climate change dry and brittle the area.
According to the Bay Area Regional Report, since 1950 the Bay Area has already increased in temperature by 1.7 degrees Fahrenheit and local sea level is eight inches higher than it was one hundred years ago. Future climate will render the Bay Area less suitable for our evergreen redwood and fir forests, and more favorable for tolerant chaparral shrub land. The regionâs seven million people and $750 billion economy (almost one-third of Californiaâs total) is predicted to be increasingly beset by more âboom and bustâ irregular wet and very dry years, punctuated by increasingly intense and damaging storms.
Unsurprisingly, according to the report the Bay Areaâs intensifying housing and equity problems have a multiplier affect with climate change. As Bay Area housing spreads further north, south, and inland the result is higher transportation and energy needs for those with the fewest resources available to afford them; and acute disparity in climate vulnerability across Bay Area communities and populations.
âAll Californians will likely endure more illness and be at greater risk of early death because of climate change,â bluntly states the statewide summary brochure for Californiaâs climate assessment. â[However] vulnerable populations that already experience the greatest adverse health impacts will be disproportionately affected.â
âWeâre much better at being reactive to a disaster than planning ahead,â said UC Berkeley professor and contributing author David Ackerly at a California Adaptation Forum panel in Sacramento on August 27th. âAnd it is vulnerable communities that suffer from those disasters. How much human suffering has to happen before it triggers the next round of activity?â
The assessmentâs data is publicly available online at âCal-adapt,â where Californians can explore projected impacts for their neighborhoods, towns, and regions.
