California’s climate, characterized by warm, dry summers and mild
winters, makes the state’s water supply unpredictable. For
instance, runoff and precipitation in California can be quite
variable. The northwestern part of the state can receive more
than 140 inches per year while the inland deserts bordering
Mexico can receive less than 4 inches.
By the Numbers:
Precipitation averages about 193 million acre-feet per year.
In a normal precipitation year, about half of the state’s
available surface water – 35 million acre-feet – is collected in
local, state and federal reservoirs.
California is home to more than 1,300 reservoirs.
About two-thirds of annual runoff evaporates, percolates into
the ground or is absorbed by plants, leaving about 71 million
acre-feet in average annual runoff.
The Ojai Valley agency planned a roughly $1 million project to

While Southern Californians appreciate the work that’s needed
to provide a consistent water supply, most people carry on with
their busy lives as long as water comes out of the taps.
Because water pipelines are out of sight, they are also mostly
out of mind. But try to imagine for a moment a day when water
didn’t just flow from the faucets.
Almost a year after wildfire ravaged the small wooded town,
residents are still advised not to drink or bathe with tap
water. Crews have hauled away more debris than workers took
from the World Trade Center after 9/11. They’re nearly done.
A Monterey County Superior Court judge has called a halt to
work on the California American Water desalination plant
project, at least temporarily, while a California Coastal
Commission appeal challenging the project’s source wells is
Kings County’s groundwater management will begin a 20-year
transformation in 2020. Five local groundwater agencies
presented more information behind the groundwater
sustainability plan in a public outreach meeting Thursday
Gov. Gavin Newsom on Saturday signed a law intended to counter
Trump administration plans to increase oil and gas production
on protected public land. The measure bars any California
leasing authority from allowing pipelines or other oil and gas
infrastructure to be built on state property. It makes it
difficult for drilling to occur because federally protected
areas are adjacent to state-owned land.
In case you’ve noticed some of the storm drains in the City of
Pasadena covered, the Department of Public Works wants you to
know it’s just following the rules. The covers are “catch
basins” and they are used for gathering trash samples
throughout the City to help in complying with mandated Total
Maximum Daily Load limits.
Sacramento Metro Fire has a new tool to assist in their
firefighter trainings, which also helps recycle millions of
gallons of water at the same time. The Pump Pod is a mobile
tank that assists in catching and recycling thousands of
gallons of water during firefighter training exercises.
The forced blackout imposed by Pacific Gas & Electric Co. to
reduce fire danger amid high winds has slowed agricultural
activities in some parts of California to a crawl as shuttered
processing facilities have caused a backup in harvests.
The number of wildfires burning across the western United
States over the past 6 decades has been steadily increasing,
and those fires are growing larger and more severe, especially
in mountain areas where more than 65% of clean water resources
for the West’s 75 million people originate. What happens when
fires intersect water resources is the subject of two new
papers in Hydrological Processes.
Gov. Gavin Newsom’s veto of Senate Bill 1 means the honeymoon
may be over with environmental groups who saw the bill as a
bulwark to protect California’s water quality and endangered
species from the Trump administration’s regulatory slashing.
Arizona’s top water official presented new long-term
projections Friday showing that Pinal County doesn’t have
enough groundwater to provide for the fast-growing area’s
cities, farms and many planned subdivisions over the coming
The court denied the petitioner’s challenge, which questioned
the validity of the county’s Environmental Impact Report,
according to the Statement of Decision. Crystal Geyser
purchased the former Coca Cola water bottling facility on Ski
Village Drive in 2013 with hopes of bottle sparkling spring
water and eventually producing Juice Squeeze drinks there.
While many hail the Sustainable Groundwater Management Act as a
success in state legislation and others say the law represents
government overreach, most seem to agree: It could change
agriculture and the economy in the San Joaquin Valley in a very
big way. In this interview, we talk about the nuts and bolts of
SGMA with Stephanie Anagnoson, Director of Water and Natural
Resources with Madera County.
On Friday night the governor signed Assemblyman Todd Gloria’s
Assembly Bill 1413, which will support local referendums on
transit funding, and Assembly Bill 1290 by Gloria and Sen. Toni
Atkins that clears the way for the pioneering Pure Water
Working to “Make Every Source a Resource” and striving toward a
more sustainable future, East Valley Water District Board of

A provider of drinking water in Sacramento County is seeking
reimbursement from the U.S. Air Force for a filtration system
it installed to take contaminants out of groundwater near the
former Mather Air Force Base.
Efforts to extract lithium at the Salton Sea could unite
environmentalists — who decry the destructive evaporation ponds
used to produce the metal in South America — and national
security hawks, who are loathe to rely on other countries for a
mineral poised to play a key role in powering the U.S. economy.
While cities on the Monterey Peninsula have been working to
address housing needs and the business community is actively
looking to create more jobs, there is one component they all
need to complete their plans – reliable, drought-proof access
Conditions tipped from bleak into officially alarming in
late August when the U.S. Environmental Protection Agency
announced that the water residents drink, cook with and bathe
in had been contaminated with arsenic at 10 times the allowable
The draft plan … includes some provisions designed to
strengthen oversight of lead in drinking water. But it skips a
pricey safety proposal advocated by public health groups and
water utilities: the immediate replacement of six million lead
pipes that connect homes to main water pipes. The proposed new
rule would also more than double the amount of time allotted to
replace lead pipes …
Nearly 600 former Environmental Protection Agency officials are
calling on Congress to investigate the Trump administration’s
“inappropriate threat of use of EPA authority” against the
state of California over recent environmental policies.
In its effort to establish a new, drought-proof source of water
that could serve a half-million Southern California homes, the
Metropolitan Water District on Thursday, Oct. 10 unveiled a $17

To survive the next drought and meet
the looming demands of the state’s groundwater sustainability
law, California is going to have to put more water back in the
ground. But as other Western states have found, recharging
overpumped aquifers is no easy task.
Successfully recharging aquifers could bring multiple benefits
for farms and wildlife and help restore the vital interconnection
between groundwater and rivers or streams. As local areas around
California draft their groundwater sustainability plans, though,
landowners in the hardest hit regions of the state know they will
have to reduce pumping to address the chronic overdraft in which
millions of acre-feet more are withdrawn than are naturally
Explore the Sacramento River and its tributaries through a scenic landscape as we learn about the issues associated with a key source for the state’s water supply.
All together, the river and its tributaries supply 35 percent of California’s water and feed into two major projects: the State Water Project and the federal Central Valley Project. Tour participants will get an on-site update of Oroville Dam spillway repairs.
Building the capacity to resolve disputes and work together is
critical for a sustainable water future. However, recent
analysis conducted by Water in the West … suggests that
alternative dispute resolution processes are rarely used even
when included in water management agreements.
Fish in San Geronimo Creek are again the source of litigation.
… For the average Marinite to know what’s at stake, fish
proponents and the county need to answer three obvious but, so
far, unanswered questions.
Cities, counties and regional water districts throughout the
Sacramento Valley and Bay Area are urging users to cut down on
water use during Pacific Gas and Electric Co.’s public safety
power shutoff, which has blacked out hundreds of thousands of
customers since the early morning hours of Wednesday.
Partially inspired by the Flint, Michigan, water crisis, the
Environmental Protection Agency announced a new rule to reduce
exposure to lead from drinking water around the country on
Thursday. … Wheeler said the new rule will help remove the
most corrosive pipes with the highest risk of releasing lead
The majority of California’s elected leaders oppose Trump’s
plans. A majority of Californians also believes the state
should ban the dangerous practice called “fracking,” which
injects poisonous, cancer-causing chemicals deep into the
The removal of the Upper York Creek Dam will not begin in 2019
as previously planned, but the project is still on schedule to
be complete by the end of 2020. … The city now plans to do
both phases in 2020, after last-minute design changes failed to
win regulatory approval in time for the 2019 construction
season ending Oct. 31.
Typical discussions about homelessness tend to focus on its
most obvious problem, a lack of shelter. What often gets left
out, though, are the tangential issues that arise from the
crisis. On Oct. 3, the Central Coast Regional Water Quality
Control Board set out to examine one such issue: the ways in
which homelessness and water quality intersect.
California’s largest inland lake, the Salton Sea, lies in the
Imperial and Coachella valleys. The lake, which is more than 50
percent saltier than the Pacific Ocean, is becoming more salt
than water because it’s essentially evaporating. The lake and
the area that surrounds it — once hotspots for tourism and
wildlife — have essentially become ghost towns.
For the first time in five years, Tustin is looking at passing
along those increases to consumers through a rise in rates.
Early next year, the City Council will vote on a multi-year,
incremental rate hike. If council members approve the staff
proposal, rates almost immediately will increase 6% per year
for five years.
I have been writing about drinking water issues for the past
fifteen years and often been struck at how little attention the
Safe Drinking Water Act (SDWA) receives in our field. Passed
just two years after the Clean Water Act, it gets scant or no
coverage in environmental law casebooks and is rarely taught in
environmental law courses.
A staggering number of Chinook salmon are returning to a
California river that hasn’t sustained salmon for decades due
to agricultural and urban demands, giving biologists hope that
threatened fish are finally spawning in their native
grounds without human help.
A big part of the reason for Fresno County falling short of the
No. 1 ranking those years was due to California’s five-year
drought that began in late 2011— the worst in the state’s
recorded history — causing major water shortages in the western
end of Fresno County that forced farmers there to limit their
farming or let fields go fallow.
Pumped Hydro Storage LLC is seeking approval from the Federal
Energy Regulatory Commission to study the sites east of Grand
Canyon National Park over three years. None of it will move
forward without permission from the Navajo Nation. Navajo
President Jonathan Nez said he’s been briefed by tribal
economic development officials about the proposals — but hasn’t
talked with anyone from Pumped Hydro Storage.
Building on the Governor’s call to “position California to meet
broad water needs through the 21st Century” there are unique
opportunities in the Sacramento River Basin to more effectively
integrate 21st Century infrastructure into our multi-benefit
water management approaches to help achieve resiliency.
The city of Oceanside is offering tours to experience Pure
Water Oceanside, an innovative program that will purify
recycled water to create a new local source of high-quality
drinking water that is clean, safe, drought-proof and
environmentally sound. Pure Water Oceanside will produce enough
water to provide more than 32% of the city’s water supply, or
3-5 million gallons per day.
As CO2 levels rise more rapidly than predicted, we need to
re-assess infrastructure needs, from sewage plants and roads
located along the coasts as the sea level rises, to our water
supply and delivery system. “Infrastructure” might sound like a
boring word, but it won’t be so boring to any of us if water
doesn’t come out of the tap or untreated sewage is spilled into
California’s Central Valley is one of the most productive
agricultural regions in the United States… But a seven-year
drought has threatened the viability of the valley’s farmland,
and many rural communities have suffered greatly as a result.
Joris Debeij’s short documentary When a Town Runs Dry offers a
window into the front lines of the water crisis.
The Senate approved almost $20 million in funding to address
sewage flows along the border. Sen. Dianne Feinstein, who
secured language in three different appropriations bills for
the 2020 fiscal year, called the spills that send millions of
gallons of raw sewage from Tijuana to San Diego,
An expert in water governance, Anita Milman’s research focuses
on understanding the interplay of technical, institutional and
social dimensions of water within governance processes. …
Below, Milman discusses keys to successful groundwater
governance, implications toward achieving water security and
her research activities at Stanford.
After morning services, Florin Ciuriuc joined the line of
worshipers waiting to fill their jugs with gallons of free
drinking water from a well on the property, a practice church
leaders had encouraged. Church leaders boasted it was the
cleanest water in Sacramento, according to Ciuriuc. In fact,
test results showed the water contained toxic chemicals from
firefighting foam used for decades on a now-shuttered Air Force
base a mile away.
In July of 2015, California’s forests began to crumple. Parched
from more than three years of severe drought, trees died in
droves, transforming entire swaths of the Sierra Nevada from
vibrant green to dull, lifeless red. … But as Mukesh Kumar
and his colleagues would discover, California’s trees had
sounded a subtle death knell long before they breathed their
Over the past decade, state and federal agencies have continued
to publish peer reviewed scientific research that largely
strengthens our understanding of how the volume, timing,
temperature, and quality of water – and the operations of
existing dams and water diversion facilities, including the
state and federal water projects – adversely affect salmon and
other fish and wildlife.
The National Marine Fisheries Service owes an explanation for
why it decided that two dams on the Yuba River do not adversely
affect threatened Chinook salmon, steelhead and green sturgeon,
three Ninth Circuit judges ruled Thursday.
Areas under Clean Water Act, or CWA, jurisdiction are not
prohibited from being filled for development, but if developed,
the act does require federal oversight, permitting and full
mitigation for any loss of wetlands and wildlife habitat.
Removing CWA protections would likely make the 1,400-acre salt
pond site more profitable to develop, and thus more difficult
to purchase for tidal marsh restoration.
The morning dawned hot and sticky Tuesday, Sept. 24, when a
slew of volunteers and scientists clad in T-shirts and hip
waders along the Lake Elsinore shoreline. Their goal? To catch,
measure, tag and release fish in the city’s namesake lake all
in the name of conservation.
Hotter-burning wildfires are transforming California’s forests,
and not for the better. A new study from UC Davis finds
high-intensity fires leave fewer trees and a less diverse
population of plants behind. … Those intense fires transform
forest into shrubland. And according to Richter, the more
frequent and the larger the area burned at these high-severity
sites, the larger the shrub fields left behind.
Whenever I visit my hometown of Orange County, California, I
get to sip some of the purest drinking water in the US. The
quality is sometimes hard to spot, since many drinking-water
contaminants are odorless, tasteless, and invisible to the
human eye. Even in cities where the water is contaminated with
lead, residents have reported that their taps are crystal
clear. But in Orange County, the water is actually as clean as
The loss of oyster reefs in the bay has affected its entire
ecosystem. Oysters are natural filter feeders, filtering out
small sediments and contaminants in the water. The unclean
water has made it difficult for underwater grass to grow,
reducing habitats for fish. The California Shellfish Initiative
… works to advance local restoration plans for the bay,
partnering with the California Coastal Conservancy to rebuild
its native oyster reefs and wetlands.
The ambitious tree-planting project falls under the purview of
Rachel Malarich, the city’s forest officer—a job that was just
created in August to “oversee the growth of Los Angeles’ urban
forest” as part of Garcetti’s Green New Deal. … The project
will grow what’s already the largest urban forest in the
country, making what happens in Los Angeles an important model
for other cities looking to go green.
California has embarked on a statewide assessment to identify
the scope of PFAS contamination in the state, focusing
primarily on PFOA and PFAS. … Most recently, on August 23,
2019 the State Water Board lowered notification levels for PFOA
and PFOS to 5.1 ppt and 6.5 ppt, respectively. The announcement
also stated that response levels for these contaminants will be
updated this fall.
Here in Kern County, state-mandated water budgets presented by
several large ag water districts and groundwater sustainability
agencies have painted a far rosier groundwater picture. So
rosy, the numbers simply couldn’t be believed…
Pulling weeds is not usually a great way to start a party. But
filling a dumpster with invasive species was just the right
activity to commemorate the 10th anniversary of Tijuana River
Action Month on Saturday.
The spread of antibiotic resistant genes (ARGs) through the
water system could put public safety at-risk. Researchers
studied and compared samples from an advanced groundwater
treatment facility in California and groundwater aquifers…
They found that the advanced groundwater treatment facility
reduced nearly all targeted ARGs to below detection limits, but
groundwater samples had a ubiquitous presence of ARGs …
As a berry farmer in Coastal California my entire life, I have
been a vocal supporter of groundwater regulation. … We are
now seeing the profound risk of losing this critical resource,
unless we collectively act soon to preserve groundwater
resources for both the next decade and future generations.
There should be no “acceptable” amount of risk we’re willing to
take when it comes to water quality or the health of our
children and families. From Los Angeles to Sacramento to
Washington, D.C. — in all the places I’ve worked — this belief
has fueled my desire to fight for clean and safe water in our
The Trump administration’s latest effort to dramatically boost
oil and gas production is landing in California, with the
Interior Department on Friday opening up 720,000 acres between
the Bay Area and Fresno to potential drilling.
A UC Cooperative Extension survey of California registered and
unregistered marijuana growers will help researchers,
policymakers and the public better understand growing practices
since cannabis sales, possession and cultivation first became

Katie Fyhrie, a grower at Cloverleaf Farm in Davis, Calif.,
worries that the farm won’t be able to keep producing stone
fruits—which depend on the timing and duration of winter
chill—in the long-term. … With that in mind, Fyhrie and her
team have started growing elderberries.
Scientists have increasingly found that loss of property and
life from fire is overwhelmingly the result of precariously
placed housing in and bordering wildland areas — residential
developments that are, themselves, a major driver sparking
The project is the first of its kind to tap agricultural
run-off among a variety of wastewater sources for conversion
into potable, drinking water that would represent about a third
of the Monterey Peninsula’s new drinking water supply.
