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.
For a moment as columns of sunlight drifted through the pines
with the cobalt surface of Lake Tahoe in the background, it
seemed as though the partisan rancor so characteristic of this
political moment might temporarily evaporate. But such
congeniality was short lived, if it ever lived at all.
Outside the walls of the lab lies an environment increasingly
unfit for fish like delta smelt. The Sacramento-San Joaquin
Delta, some 40 miles inland from the San Francisco Bay, is a
1,100-square-mile tidal marsh that for millennia teemed with
salmon, shellfish, tule elk, deer, and waterfowl — all of which
supported a Native American population of about 300,000 people.

The headwaters of Blue Creek is also among the tribe’s most
sacred sites, said Gene Brundin, a member of the tribe’s
cultural committee. The stream begins at a place called Elk
Valley near Chimney Rock and its cold water ensures the
viability of the salmon runs, he said.
California’s water regulator voted Tuesday to spend $1.3
billion over the next 10 years to provide safe drinking water

Despite being one of the wettest seasons, Cal Water officials
are saying conservation should be on Californians’ minds. Cal
Water special projects manager, Susan Cordone, said, “It is
important to continue to practice conservation. One wet winter

Although prescribed burns have been part of federal fire policy
since 1995, last year the Forest Service performed them on just
one per cent—some sixty thousand acres—of its land in the
Sierra Nevada. “We need to be burning close to a million acres
each year, just in the Sierras, or it’s over,” said Jeff Brown,
manager of a field station in the Tahoe National Forest.
Desalination began to lose its urgency among Californians and
their public officials two years ago, after the drought-busting
winter of 2016-17, when heavy rain and snow ended dry
conditions in most of the state. The idea of drawing potable
water from the sea became even less of a priority this year,
when an autumn of record-level fires gave way to one of the
state’s wettest winters on record.

In June, Kathy Joseph learned that the fungicide she has been
spraying on her grapes for decades could be drifting onto the
cannabis. Unlike food crops, cannabis can’t be sold if there’s

California was the last Western state to pass legislation
regulating groundwater: the Sustainable Groundwater Management
Act of 2014 arrived after more than a century of development,
intensive agriculture, bouts of drought and the looming threat
that our aquifers will dry up. But the details of who would get

What would happen if we ran out of water? For an increasing
number of people, that question is moving from a hypothetical
to a reality. New data from the World Resource Institute show
that a quarter of the world’s population is at high risk of
running out of water.
During the past 107 years, daily air temperatures measured in
Tahoe City have increased. The average daily maximum
temperature has risen by 2.25 degrees Fahrenheit, and the
average daily minimum temperature has risen by 4.43 degrees.
According to the report, the number of days when air
temperatures averaged below freezing has declined by about 30
days since 1911, though year-to-year variability is high.
Between 1901 and 2016, temperatures increased across the
Southwest, with the greatest upturns in California and
Colorado. … Meanwhile, growing population, aging
infrastructure, and groundwater depletion are also compounding
long-standing water scarcity issues in the region. These
mounting pressures have a bevvy of potential implications, from
human health and ecological function, to food and energy
In a newly published study, my colleagues and I analyze
year-to-year variations of future snowpack to see how
frequently western states can expect multiple years in a row of
snow drought, or very low snow. We find that if climate change
continues relatively unabated, consecutive years with snow
drought conditions will become much more common…
Marin residents living in the Ross Valley will see a 3%
increase in the annual stormwater drainage fee to finance flood
control projects. … Following the 3% increase, homeowners
will be paying $149.28 annually. The Ross Valley has been
dogged by flooding over the past century.
In recent years, algae blooms – actually microscopic bacteria
called cyanobacteria – have erupted in hundreds of lakes
nationwide, putting at risk Americans whose drinking water
comes from those lakes, or who swim, ski or fish in them. If
ingested, microcystins can cause adverse health effects in
people and animals, ranging from skin rashes to serious illness
and even death.
Ivan Soto has aspired to produce research with a positive
impact on the public — not just to benefit the academic
community. … His research examines the power dynamics of
infrastructure and water politics through an environmental
history of southernmost California’s Imperial Valley along the
Many farmers probably haven’t read the new report from the
United Nations warning of threats to the global food supply
from climate change and land misuse. But we don’t need to read
the science — we’re living it. Here in the San Joaquin Valley,
one of the world’s most productive agricultural regions,
there’s not much debate anymore that the climate is changing.
NOAA’s Climate Prediction Center estimated the chances of
neutral conditions sticking through the winter at about 55%. An
El Nino has a 30% percent chance of returning, while La Nina
has a 15% chance of forming, according to the center.
A partnership of state, local and conservation groups,
including Trout Unlimited, is engaged in a restoration effort
that could serve as a template for similar regions across the
West. Centered around the high plateau near Kremmling, a town
of about 1,400 people in northern Colorado about 100 miles west
of Denver, the partnership aims to make the river function
better for people and the environment.
Nearly two dozen government officials met Wednesday to discuss
options for one of the state’s most important and imperiled
water sources. Scoggins Dam was built in the early 1970s to
hold back water from the Tualatin River to form Hagg Lake. In
recent years, it has been classified as a seismically at-risk
dam that needs to be modified in order to reduce downstream
hazards in the event of a large earthquake.
High in the headwaters of the Colorado River, around the hamlet of Kremmling, Colorado, generations of families have made ranching and farming a way of life, their hay fields and cattle sustained by the river’s flow. But as more water was pulled from the river and sent over the Continental Divide to meet the needs of Denver and other cities on the Front Range, less was left behind to meet the needs of ranchers and fish.
“What used to be a very large river that inundated the land has really become a trickle,” said Mely Whiting, Colorado counsel for Trout Unlimited. “We estimate that 70 percent of the flow on an annual average goes across the Continental Divide and never comes back.”
Higher-priced bottled water won’t affect average Californians
much; either they can afford to not think about the price hike,
or they have access to safe tap water. It is our most
vulnerable—roughly a million residents who depend on bottled
water due to contaminated pipes—who will suffer. That’s one in
forty Californians, predominantly people of color, unable to
use their tap water to drink, cook or wash.
From the infamous “Garbage Patch” islands of floating plastic
to the guts of fish and bellies of birds, plastics of all sizes
are ubiquitous and well-documented in the ocean. But little
data exists on microplastics in lakes. If Katie Senft’s
preliminary research at one of the clearest, cleanest lakes in
the world is any indication, the problem is widespread in
freshwater systems, as well.
Riverside County supervisors Tuesday approved an aggregate
$1.79 million in expenditures for a project to clear the Salton

Litigation over water rights in western Nevada began as early
as 1864 on the Carson River and just a bit later the Truckee
River when the first retaining dam was built at Lake Tahoe’s
outlet. It was just the beginning of bi-state water wars
between the Silver State and California, a volatile conflict
that continued for well more than a century.
The Sacramento County Water Agency says customers have alerted
the agency to the scheme, in which the caller claims county
officials will shut off their water within 30 minutes if they
don’t make a payment, the county Department of Water Resources
said Tuesday in a news release.
Last December, the board voted not to adopt a proposal to raise
rates by an average of 3 percent over the three years, sending
the district back to work with its consultants to come up with
a different plan that would be best for ratepayers.
Microcystins are poisonous toxins that can form in blooms of

The general rule of thumb had been that El Niño years — when
the sea surface in a region off the coast of Peru is at least 1
degree Celsius warmer than average — tend to have more
rainfall, and La Niña years, when that region is 1 degree
Celsius cooler than average, tend to have less rain. But that
simple rule of thumb doesn’t always hold true.
Across the United States, more than 460,000 households, or

the persistence of “plumbing poverty” in the U.S. …
Next spring, the Yurok Tribe will begin its Redwood Canoe
Adventure Tour and it will utilize six hand-crafted redwood
canoes made using traditional tribal tools and techniques. …
According to the tribe, it’s an opportunity you won’t find
anywhere else in the world due to the unique relationship
between the Yurok people and the Klamath River.
Whenever the price of other water goes up, desalinating Pacific
waters becomes more enticing. It will become more so if the
price of filtering minerals out of salt water drops. But if the
price and availability of fresh water remains reasonable, as it
surely will be this year, desal stays in the back seat.
Whether you are a water utility manager, elected official, or
homeowner, future water availability is a concern. There are
several factors fostering that concern and one of them is
climate change. … But as the empirical evidence mounts and a
once doubtful citizenry become more informed, it is instructive
to review what a changing climate fundamentally means to
California’s water resources; arguably our most important.
San Bernardino Valley Water Conservation District reported more
than 20 billion gallons of water captured, a new record for
captured groundwater recharge. … This is a 30-year record
with 1987 being the last year this much groundwater was stored
into the region’s aquifers. Prior to that, 20 billion gallons
of storage had not been achieved since the late 1940s.
As the Tejon Tribe casino makes its way through the regulatory
process, concerns have been raised over the impact the complex
will have on the county’s groundwater. However, county
officials believe the casino may actually use less water than
the farms that currently occupy the planned site just south of
Bakersfield. But questions do remain …
While other regions grappled with destructive waves and rising
seas, the West Coast for decades was spared by a rare
confluence of favorable winds and cooler water. This “sea level
rise suppression,” as scientists call it, went largely
undetected. Blinded from the consequences of a warming planet,
Californians kept building right to the water’s edge. But lines
in the sand are meant to shift.
Ample water resources in northern areas of California are
balanced by huge demands from Central Valley agriculture and
the large populations in hotter, drier southern areas such as
Los Angeles and San Diego. California uses the most water of
any state, according to the U.S. Geological Survey, up to 9
percent of all withdrawals from the national supply.
Holly Foster, whose family runs cattle in Butte and Plumas
counties, said her ranch lost power during a shutoff in June
that affected Butte, Napa, Solano, Yolo and Yuba counties. Her
cattle in Butte County are particularly vulnerable because she
relies on electricity to pump water from wells.

Hiding and waiting is a great strategy as long as droughts are
temporary. But as our climate becomes warmer, increased
evaporation will make it effectively ever drier, and rainfall
will arrive ever less predictably at the right time of year.
Native plants will thus face long-term increases in water
stress, often exacerbated by intensified fire and shifts in
their delicate coexistence with exotic species.
A Butte County project will expand its partnership with Chico
State and Stanford University to analyze available groundwater
systems. … It’s a groundbreaking project for water management

Ventura started paying for its right to state water in 1971. On
Monday night, policymakers took the biggest step yet to being
able to access it. The Ventura City Council voted 6-0 to
approve a study certifying no major environmental impacts would
result from building the 7-mile pipeline near Camarillo. The
action means the city’s next move is hiring a consultant to
draft the interconnection’s final design.
In a weather anomaly verified for the first time, a weather
station in Siskiyou County recorded the highest annual
precipitation for California’s weather season. The weather
station at Stouts Meadow, located at an elevation of 5,400 near

precipitation for the season.
Steven Appleton hopes his status as owner will amplify his
voice — and possibly his ability to obstruct — when officials
launch infrastructure projects that disregard his vision for
the river. … “The whole point of this restoration is the
river,” Appleton said. “The river itself right now is the least
attended aspect of it.”
The 110-mile Russian River and all its tributaries move through

For years, bottled water has served as one of the only
dependable options for consumption and sanitary needs, serving
as a simple way for communities to access affordable and
available water. Yet, a proposed bill in the California state
legislature, Assembly Bill 792, has the potential to impose a
de facto tax on bottled water, leading to significant jump in
cost, and making it unaffordable for many disadvantaged
Tammy Waller thought she was one of the lucky ones after her
home in Magalia survived California’s most destructive wildfire
ever, but her community remains a ghostly skeleton of its
former self. Hazmat crews are still clearing properties, and
giant dump trucks haul away toxic debris. Signs on the water
fountains in the town hall say, “Don’t drink.”
New regulations from the California Public Utilities Commission
have authorized energy companies like PG&E to turn off
power to avoid or reduce the risk of wildfires… For
commercial customers — like other utility companies — it could

repercussions for their customers. The California Water Service
is already preparing to take that hit this summer.
A major barrier to using urban stormwater is that it’s dirty.
Rain starts picking up contaminants the moment it hits
rooftops, streets, and other hard surfaces, as well as
landscapes laden with fertilizer and herbicides. … New
research shows that a cost-effective, low-tech approach can go
a long way toward cleaning up urban stormwater.

There was a glint in Michael Boland’s eyes as he watched cars
zooming along the Presidio Parkway over an ugly panorama of
broken asphalt, weeds and construction debris behind a
chain-link fence next to Crissy Field. The chief of park
development and visitor engagement for the Presidio Trust was
excited as he envisioned what the vacant lot was about to
become — a picturesque lagoon surrounded by walking trails,
vivid greenery and a spectacular view.
After a years-long drought and a major wildfire, rainstorms
brought a lot of ash and debris downstream over the past year
or so. … Now, Casitas officials hope to clear a
9-foot-high pile of silt, sand and gravel before the next
rainy season. Plans call for starting work in September, but as

People may want to think twice before taking a dip in the
green-tinted water near the Parrotts Ferry Bridge at New
Melones Reservoir, according to U.S. Bureau of Reclamation
officials. The water’s greenish hue is due to a cyanobacteria
bloom that was first detected in the Middle Fork of the
Stanislaus River upstream of the reservoir on July 17.
Where Napa’s water quality is concerned, no news may be good
news. A three-year analysis of the city’s water sources showed
reservoirs meeting all federal and state limits on a variety of
