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 State Water Board today issued key documents that move the
Klamath River Renewal Corporation significantly closer to
removing four dams and re-opening 360 miles of the Klamath
River and its tributaries to imperiled salmon.
Stormwater is the rain and other water that runs off of streets
and sidewalks into nearby gutters or waterways. Communities
throughout the western U.S. are expanding efforts to collect
this valuable water resource. These projects range from
capturing water from a single rooftop or driveway to developing
large infiltration basins that recharge billions of gallons of
water each year in groundwater basins.
Registered voters who live in Mendocino have the opportunity

An analysis led by Stanford University found that temperatures
rose about 1.8 degrees Fahrenheit statewide while precipitation
dropped 30% since 1980. That doubled the number of autumn
days—when fire risk is highest—with extreme conditions for the
ignition of wildfires.
In January, water users in 21 critically overdrafted basins

Governments at all levels are beginning to review water access
policies and inequalities that inhibit public and personal
efforts to slow the spread of coronavirus. Those policies
include restoring water service to homes where water had been

Today, responding to a global pandemic is every governor’s top
priority. When we emerge from this crisis, Gov. Gavin Newsom
will face a challenge to ensure California’s future economic
and environmental health. In this context, his water policies
will represent critical decisions.
Runoff from rain and snow across the mountains of central
Arizona this year has filled reservoirs nearly to capacity
along the Verde and Salt rivers. Salt River Project’s system of
six reservoirs is now 98% full, the highest level since 2010.
Unprecedented efforts by leaders at the state and national
level have led to the kind of cooperation that will provide
valuable benefits to water users and the environment. I know

An empty lot on a 70-foot-high bluff above the ocean seemed
like the perfect place to build a house when the owners bought
the parcel for $1.8 million. Now a state ruling means they’ll
have to put the house farther away from the water, where they
won’t see the shore. It’s a result of climate change and
California’s response to it.
We have a legacy of lead in our pipes, our paint, and our soil.

In California, groundwater is a major source for drinking and
other uses. Identifying where groundwater quality is getting
better or worse is essential for managing groundwater
resources. A new study conducted by a team from the California
Water Science Center, led by Research Hydrologist Bryant
Jurgens, assessed areas of improving and degrading
groundwater-quality by using a new metric for scoring.
Arizona is sinking. The combination of groundwater pumping and
warmer temperatures is shrinking aquifers and lowering water
tables. … Today, where subsidence is worst, groundwater
pumping isn’t even monitored, and big agricultural and
anti-regulatory ideologues try to stymie any efforts to keep
tabs on how much water is being pumped.
Californians won’t have their water turned off due to unpaid
bills during the coronavirus crisis, and those who already had
it turned off will have their service restored, under action
taken Thursday by Gov. Gavin Newsom. The governor’s directive
comes in response to calls from environmental justice
organizations for assistance to low-income residents facing
mounting financial pressures.

Two 30-inch outlet pipes in the dam had been plugged with
debris since last spring, forcing the lake to rise and wash
over a spillway that state officials have deemed unsafe. But by
early February, water was again flowing out of the pipes,
allowing the lake to drop to a safe level, according to a
Shasta County Sheriff’s Office report.
So much for the March Miracle. Despite a few March storms, the
Sierra Nevada snowpack remains well below average, California
officials reported Wednesday, suggesting that water supplies
will be tight this summer and fall.
The U.S. Bureau of Reclamation has issued a new three-year

The rules take the form of a state Fish and Wildlife Department
permit that will govern State Water Project deliveries from the
Sacramento-San Joaquin Delta… But the permit does not
explicitly control the U.S. Bureau of Reclamation’s Central
Valley Project, which exports Delta water to San Joaquin Valley
farms. That means the two big government pumping operations
will likely adhere to different standards — possibly allowing
the federal project to boost deliveries at the expense of the
As the climate changes, forests have figured out a way to adapt

tree communities, particularly in more arid regions, have
become more drought tolerant, primarily through the death of
less hardy trees.
The basics of the relationship between water and energy are
well known, but California’s recent drought revealed something
surprising about this connection. When the state mandated a 25
percent drop in water use, the resulting energy savings turned
out to be even higher than expected. This prompted the
Department of Energy to find ways of making water more energy
Snow surveyors will head into the Sierra on Wednesday to take

While snow cover has increased thanks to a series of March
storms, the Northern Sierra 8-Station Index stands at 56% of
normal for the season. As of March 24, another 29.25 inches
would be needed to reach the season normal of 54.52 inches. But
the area normally gets just 9.42 inches from March 24 through
June 30. So a daunting 310% of normal precipitation would be
required to make up the deficit, according to Jan Null of
Golden Gate Weather Services.

Many of Arizona’s Native tribes have long-standing claims to
water rights that haven’t yet been settled, and a discussion of
efforts to negotiate possible agreements took center stage at a
meeting of Gov. Doug Ducey’s water council. The meeting grew
tense after Arizona’s top water official gave a presentation on
the status of tribes’ unresolved water claims, and then didn’t
allow leaders of four tribes to speak.
Those who live in the city of Los Angeles don’t need to
stockpile bottled water in the midst of growing fears about the

Former Gov. Bruce Babbitt is speaking out about widespread
problems of excessive groundwater pumping in rural areas of
Arizona, saying the state Legislature should give counties and
communities the power to protect their rapidly declining
aquifers. Babbitt appealed for action during a visit this week
to the Willcox area, where heavy pumping for farms has led to
falling water tables and left a growing number of families with
“It’s a huge problem, especially in the cities,” said Daniel
Tartakovsky, a professor of energy resources engineering at

On Monday, Lilac Solutions and the Australian company
Controlled Thermal Resources announced they’re partnering to
develop a lithium-extraction facility at the Salton Sea. The
Australian firm is trying to build the area’s first new
geothermal power plant in a decade, a project that would be far
more lucrative if the super-heated underground fluid could
produce lithium in addition to electricity.
The Santa Clarita Valley Water Agency (SCV Water) has announced
that they are set to voluntarily shut down 13 additional wells

After a prolonged period of mostly dry conditions, the Tahoe
Basin finally reported impressive 24-hour snowfall totals
Sunday morning: As of 8:30 a.m., Squaw Valley had recorded 18
inches at its base and up to 30 inches at its highest peaks.
Tahoe City measured 23 inches, Homewood 33 and Incline Village

Sierra could see another one to three feet of snow.
The case, titled Baley v. United States, was filed 19 years ago
when the U.S. Bureau of Reclamation re-allocated Klamath River
irrigation water to threatened and endangered species. A
favorable outcome would mean upwards of $30 million
collectively in compensation for irrigators named in the case.
If corporations can have the rights of people under the law,
why not rivers? The question made sense to Will Falk, and he
answered it yes. Falk is a lawyer, and he got to represent the
Colorado River in a lawsuit. So he spent time along the river,
in something of a conversation with it. Falk tells the story in
his book How Dams Fall.
Much-needed snow will blanket California’s Sierra Nevada high
country this weekend into next week, bringing hope of a
“Miracle March” that could replenish vital, water-providing
snowpack after a record-dry February.
The Retrofit Project would mitigate earthquake hazards
currently threatening the Redwood Valley County Water
District… The county said the project would replace
approximately 10,577 feet of main water lines, include
installation of around 3,300 feet of new water main lines, and
replace 146 water services lateral connections. The project
will cost an estimated $6,200,000, including construction
support and contingency.
As discussed below, in the case of west coast salmon, the
scientific evidence is clear that the replacement assumption
has proven faulty as the total abundance of salmon declined at
the same time the propagation and release of hatchery salmon
Both water companies that serve Salinas will halt all water
shutoffs during the state of emergency brought on by the
COVID-19 pandemic. Salinas has a large population of
hospitality workers that commute to the Monterey Peninsula

Forecasting snowfall and determining long-term trends of snow
climatology are inherently challenging, but the research team
at Climate Central has produced an analysis of snowfall trends
across the United States. While no single overall national
trend in snowfall can be discerned from the results, clear
regional and seasonal patterns do emerge. In almost all areas
of the country, snow is decreasing in the “shoulder”
seasons—fall and spring.
In less than a day, a storm Tuesday more than doubled the total
rainfall that some parts of Southern California had received
all year. More precipitation is on the horizon for at least the
rest of this week. But will the change be enough to turn this

The new rules allow the federal Central Valley Project to kill
100 percent of baby winter run Chinook salmon below Shasta Dam
for three years running. Chinook salmon live for three
years, so authorizing the Bureau of Reclamation to kill every

The 2020 ocean abundance projection for Sacramento River fall
Chinook, the driver of West Coast salmon fisheries, is
estimated at 473,200 adult salmon, higher than the 2019
forecast. However, the Klamath River fall Chinook abundance
forecast of 186,600 adult salmon is lower than the 2019
forecast and will likely result in reduced fishing opportunity
in the areas north of Pt. Arena…
An important new study finds that irrigated crop production
accounts for 86 percent of all water consumed in the western US
— and of all the water used on western farms, by far the
largest portion goes to cattle-feed crops such as alfalfa and
grass hay. To alleviate the severe shortage of water in the
region, study authors suggest rotational fallowing farmland
could be a simple and affordable means of dramatically reducing
water use in the region.
In partnership with the Diablo Water District, the Ironhouse

As sea levels rise, so do the waters in the bay, which connects
to the Pacific Ocean through the Golden Gate. That relationship
between rising ocean levels and rising bay levels is well
known. What is less obvious is that groundwater levels are
rising as well, adding another variable to the region’s
equation of increasing flood risk.
The Cuyama Valley is the driest agricultural region in the
county; the valley floor gets just a little more rain than the

It was a busy time for California water issues last month when
Trump visited the San Joaquin Valley, signed the Record of the
Decision on the biological opinions which govern the operations
of the state and federal water projects (along with another
Presidential memo), which was promptly followed by the state
filing of a lawsuit the next day. … So not surprisingly, the
voluntary agreement was top of the agenda the following week at
the February meeting of Metropolitan’s Bay Delta Committee.
One day after President Trump tweeted his support, Senate
Majority Leader Mitch McConnell (R-Ky.) is expected to take
steps today to bring to the floor legislation that would
permanently fund the Land and Water Conservation Fund and
address the national parks maintenance backlog, senators said.
… Trump’s tweet was an election-year about-face from his
latest budget proposal, which recommended virtually eliminating
the popular, bipartisan program.
The Glenn-Colusa Irrigation District celebrated its 100-year
anniversary in February, according to a press release. The

If you live in Southern California or Silicon Valley, you might
be surprised to learn that your local water district (a member
agency of the State Water Contractors) is siding with the Trump
Administration, and defending Trump’s plan to increase water
diversions, despite the widespread acknowledgement that this
plan is likely to drive salmon and Delta smelt extinct.
Utah’s booming population growth and rapid economic development
means the need for more water, a higher level of conservation
and wise development of water supplies, which are not infinite.
With that in the backdrop, the Utah House of Representatives on
