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 Colorado River is in trouble. More than two decades of
megadrought fueled by climate change have sapped its supplies,
and those who use the river’s water are struggling to rein in
demand. Now, with current rules for river sharing set to expire
in 2026, policymakers have a rare opportunity to rework how
Western water is managed.
Rainfall and snow storms boosted California’s groundwater
supplies and replenished the Sierra Nevada snowpack, but
scientists say dry conditions in the summer — and starting as
soon as this weekend — could reverse that progress. …
temperatures in California — including in San Francisco — are
forecast to climb over their usual seasonal highs. That
could accelerate the rate at which the state’s snowpack melts,
according to Andrew Schwartz, lead scientist and
station manager at the UC Berkeley Central Sierra Snow
Laboratory …
After another wet winter, record rainfall has turned California
green and replenished the state’s reservoirs, which had been
perilously low during the worst days of the drought. Lake
Oroville, the state’s second-biggest reservoir, often serves as
a rainfall barometer. As of Tuesday, Oroville was at 100%
capacity, according to data from the state Department of Water
Resources. … The left photograph shows Enterprise Bridge
on Dec. 21, 2022, when the lake was at 29% of its total
capacity. The right side shows the same area April 24, 2024,
when the lake was at 96% of capacity — a figure it has now
eclipsed. As of May 7, Lake Oroville was at 128% of its
historical level. Lake Shasta, the state’s largest reservoir,
was 97% full Tuesday, or 115% of its historical level.
California’s reservoirs are not only vital to the state’s
complex water systems, providing millions of people and the
state’s agricultural economy with needed access to water;
they’re also important gauges for how healthy the state is
overall. This year’s at-capacity reservoirs have been a boon
for a region besieged by drought over much of the past decade,
but more work is needed to help ensure a plentiful and
water-wise future for the most populous state in
America. Enter Sites Reservoir, a long-in-the-works
project that aims to be the biggest reservoir development in
nearly half a century. It’s been a massive dream for
decades, an idea first worked up by landowners and water
districts northwest of Sacramento. Thanks to a new infusion of
federal cash, the proposal is closer than ever to actually
happening — but not without a very real cost.
A new study found that the Colorado River may experience a
rebound after two decades of decreased flows due to drought and
global warming. “Importantly, we find climate change will
likely increase precipitation in the Colorado headwaters,”
Professor Martin Hoerling, the study’s lead author, wrote to
The Salt Lake Tribune in an email. “This will compensate some
if not most of the depleting effects of further warming.”
Recently published in the Journal of Climate, the study by
researchers at the University of Colorado Boulder’s Cooperative
Institute for Research in Environmental Science used data from
the Intergovernmental Panel on Climate Change. … The
study’s climate projections forecast that there is a 70% chance
that climate change will lead to increased precipitation in the
Upper Basin between 2026 and 2050. That precipitation increase
could boost the river’s flows by 5% to 7%.
Residents of Allensworth are finally getting attention from a
company that installed and then abandoned hydropanels, which
make water out of thin air, several years ago. As SJV
Water reported in March, residents were frustrated they
couldn’t get support from Source Global, the company behind the
panels, after the panels had fallen into disrepair. Following
SJV Water’s story, Source Global dedicated a staff person to
oversee operations in Allensworth, said Kayode Kadara, a
community leader in Allensworth. … Kadara said Source
Global staff has been making calls to residents in town with
the hydropanels and technicians have come out to perform upkeep
and check the hydropanels. Kadara’s own hydropanels at home
were serviced. The hydropanels at Allensworth’s community
center still aren’t working though, said Kadara.

The Marin Municipal Water District is embarking on a yearlong
study to examine the impact of frequent, severe storms on the
utility’s seven dams. The district board authorized spending up
to $1.06 million to evaluate the capacity of the dam spillways,
and to use climate change projections to assess potential
hazards. The study is a response to a critical Marin County
Civil Grand Jury report published last summer. The watchdog
panel said dam safety plans for the Marin Municipal Water
District and the North Marin Water District are failing to
account for more regular “atmospheric river” storms brought on
by climate change. The grand jury recommended, among other
actions, that the water districts update their dam hazard
mitigation plans with the latest science on climate change
effects on storms.
In another move to build water resilient systems in the West
and particularly in the Colorado River Basin, the U.S. Bureau
of Reclamation announced Monday $147 million in federal grants
to help underserved communities dogged by water scarcity
issues. The funding will support 42 projects in 10 states. In
eastern Utah, nearly $6.6 million was granted to the Ute Indian
Tribe of the Uintah and Ouray Reservation which operates the
Ute Tribe Water Systems, providing water service to tribal
members.
Lake Oroville, the second-largest reservoir in California,
reached capacity on Monday for a second straight year after
another relatively wet winter. The rising waters come as state
reservoir managers have been reducing outflows from the lake in
recent weeks — as winter inflows tailed off and the threat
of downstream flooding waned — allowing the reservoir to
slowly fill to its current 899-foot elevation, or 3.52-million
acre-feet of water. … Lake Oroville contains 28% more water
than it historically has on this date. “This is great news
for ensuring adequate water supply for millions of Californians
& environmental needs,” the state Department of Water Resources
posted Monday afternoon on X, formerly Twitter.
The U.S. Bureau of Reclamation will examine the possibility of
drilling tunnels through Glen Canyon Dam to ensure water can
pass through it at low Lake Powell elevations, two
knowledgeable sources told the Arizona Daily Star. Such a
re-engineering project will be among several options the bureau
will look at due to new concerns about the ability to deliver
Colorado River water through the 61-year-old facility under
such circumstances. It could prevent a catastrophic occurrence
if lake elevations ever fall so low that no water could get
through the dam to serve farms and Lower River Basin cities,
including Tucson, Phoenix, Las Vegas, Los Angeles and San
Diego.
The Marin Municipal Water District is bolstering its strategy
on conservation with policy updates and incentive programs
designed to reduce water use by hundreds of millions of gallons
annually. The draft “2024 Water Efficiency Master Plan” is a
playbook that outlines how water is used today in the county,
and how the district can help its 191,000 customers in central
and southern Marin cut back. The plan aims to reduce water use
districtwide by more than 1,000 acre-feet a year starting in
2025, with even greater incremental reduction targets beyond
that. An acre-foot is about 326,000 gallons of water. District
staffers presented the draft plan to the board at a special
meeting on Wednesday.
Perhaps no environmental topic is as controversial in
California as the Delta Tunnel. … The tunnel is a key
part of the State Water Project’s new risk-informed strategic
plan. That strategic plan is known as Elevate to ‘28.
It lists five goals that it says will help to make the State
Water Project (SWP) “the most reliable, sustainable, and
resilient water provider for the people and environment of
California, now and for future generations.” To learn more
about the plan, ABC10 Meteorologist Brenden Mincheff invited
Tony Meyers, the Principal Operating Officer for the State
Water Project for a conversation. Here are some key takeaways
from that.
Last year, California experienced weather whiplash. After years
of severe drought, 2023 saw heavy rainfall and snowpack that
flooded the state, recharged groundwater and filled our
reservoirs. While desperately needed, we cannot pretend that
the good times are here to stay. Increasingly dry years are in
our future, and it will not be long until we find ourselves
facing drought conditions once again. The time to prepare our
water infrastructure for the future is now. Currently,
lawmakers in Sacramento are working to close a $37.9 billion
deficit. While we have made progress at the state level in
recent years — including allocating $8.6 billion in state
funding for water projects — pulling back on water
infrastructure funding now could jeopardize further federal and
local funding sources for key projects already underway. -Written by Senator Anna M. Caballero and Ric Ortega,
general manager of the Grassland Water
District.
Grand County and Northern Water have struck a deal that will
send more water running down Western Slope streams to benefit
farmers, boaters and the environment. Grand County in northern
Colorado is home to nearly 16,000 people, part of Rocky
Mountain National Park and the headwaters of the Colorado
River. Each year, four major diversion tunnels take up to
350,000 acre-feet of Colorado River water out of the county and
push it east to the Front Range. Now, the county and the water
provider are agreeing to release water in the opposite
direction, to the west.
Governor Gavin Newsom, with the support of the Department of
Water Resources (DWR) and other state agencies, signed into
effect new developments for the California Water Plan which
details water conservation efforts for the next five
years. Newsom said that the state has invested $9 billion
in the last three years, and that “I want folks to know that we
are not just victims of fate, that we recognize the world we’re
living in.” Recognizing that California will be
operating with ten percent less water in 2040 than what is
currently available, Newsom said “We put out a hotter, drier
strategy” to offset the loss. This includes plans for improving
water security, desalinization plants, stormwater capture,
water recycling, and new strategies for large-scale
conveyance.
Tribes that use the Colorado River want a say in negotiations
that will reshape how the river’s water is shared. Eighteen of
those tribes signed on to a letter sent to the Bureau of
Reclamation, the federal agency that will finalize new rules
for managing the river after 2026, when the current guidelines
expire. In the memo, tribal leaders urge the federal government
to protect their access to water and uphold long-standing legal
responsibilities. … The tribes’ letter aims to make sure
that Indigenous people, who used the Colorado River before
white settlers ever occupied the Western U.S., are not
left behind as Reclamation considers those proposals. “If you
are not at the table, you are on the menu,” Jay Weiner, a water
lawyer for the Quechan Indian Tribe, said. Weiner, who helped
craft the letter, said it aims to answer the complicated
question: What do tribes want?
Winter-like weather will make a brief return to California this
weekend, with widespread snow in the Sierra Nevada. The

fresh powder in some locations, boosting an already healthy
snowpack.
Giant pumps hum inside a warehouse-like building, pushing water
from the Sacramento-San Joaquin River Delta into the California
Aqueduct, where it travels more than 400 miles south to the
taps of over half the state’s population. But lately the
powerful motors at the Harvey O. Banks Pumping Plant have been
running at reduced capacity, despite a second year of
drought-busting snow and rain. The reason: So many threatened
fish have died at the plant’s intake reservoir and pumps that
it has triggered federal protections and forced the state to
pump less water. The spike in fish deaths has angered
environmentalists and fishing advocates, who argue the state
draws too much water from the delta while failing to safeguard
fish.
After screening proposals to expand water storage capacity, the
Marin Municipal Water District has narrowed its options. But
expansion of the Soulajule reservoir — the district’s star
prospect — is drawing mounting opposition from neighboring
ranchers who fear that their multigenerational homes and
ranches will be engulfed by the new footprint created by the
larger dam.
Against a backdrop of the Colorado River, members of the
Colorado River Indian Tribes watched Secretary of the Interior
Deb Haaland, Arizona Gov. Katie Hobbs and Amelia Flores, the
tribe’s chairwoman, sign a historic agreement on April 26 that
asserts the tribe’s right to lease portions of their allocation
of the river’s water to users away from the tribal land. The
agreement between the tribe, the Interior Department and
Arizona gives the tribe the ability to lease, exchange or store
a portion of its Colorado River water entitlement. As one
leader expressed, the tribe is stepping away from the “outdated
framework” of federal restrictions that constrained their means
to supply water to areas off the tribal land.
Pro-Russia hackers have exploited shoddy security practices at
multiple US water plants in recent cyberattacks that have hit a
wider swathe of victims than was previously documented,

A new memo from the U.S. Bureau of Reclamation is raising
concern about the infrastructure at the Glen Canyon Dam and its
ability to deliver water downstream should levels at Lake
Powell continue to decline. Environmental groups are calling it
“the most urgent water problem” for the Colorado River and the
40 million people who rely on it. … Without upgrades to
the dam’s infrastructure, the bureau’s ability to get water
downstream to the lower Colorado River basin as required by the
Colorado River Compact could be in jeopardy. Even after
record-breaking snowfall in 2023 and an above average 2024
winter, Lake Powell remains at about 32% full, according to
data from the bureau. And scientists estimate flows
in the river have decreased by roughly 20% over the last
century, with warming temperatures resulting in a
10% decrease in runoff.
Water use in California is typically thought of in three parts:
water for the environment (50%), water for agriculture (40%),
and water for communities (10%) per the Public Policy Institute
of California (PPIC). As a result, “ag” is the sector of the
economy that comes to mind first when we talk about the state’s
water supply. But the rest of California’s economy also
requires water. California’s manufacturers – one of the state’s
largest industry sectors, accounting for 11.8% of state GDP –
need water. -Written by Lance Hastings, President and CEO of

A steady stream of water spilled from Lake Casitas Friday, a
few days after officials declared the Ojai Valley reservoir had
reached capacity for the first time in a quarter century. Just
two years earlier, the drought-stressed reservoir, which
provides drinking water for the Ojai
Valley and parts of Ventura, had dropped under 30%.
The Casitas Municipal Water District was looking at emergency
measures if conditions didn’t improve, board President Richard
Hajas said. Now, the lake is full, holding roughly 20 years of
water.
Last year’s snow deluge in California, which quickly erased a
two decade long megadrought, was essentially a
once-in-a-lifetime rescue from above, a new study found. Don’t
get used to it because with climate change the 2023 California
snow bonanza —a record for snow on the ground on April 1 — will
be less likely in the future, said the study in Monday’s
journal Proceedings of the National Academy of Sciences.
… UCLA climate scientist Daniel Swain, who wasn’t part
of the study but specializes in weather in the U.S. West, said,
“I would not be surprised if 2023 was the coldest, snowiest
winter for the rest of my own lifetime in California.”
As California’s wet season comes to a close, forecasters are
already starting to talk about next winter: A La Niña weather
pattern is expected to develop. La Niña — the inverse of
El Niño — impacts weather around the world and is often

drier weather in Central and Southern California.
… While winter precipitation in California was below
normal in three of the last five La Niña years, it
was well above normal, even in Central and Southern California,

The way water used to burst from the ground in Las Vegas is
hard for me to fathom — until I actually see photos of it.
There is a reason they call Las Vegas “the meadows.” Before all
the concrete and master-planned communities, before traffic,
red cones and cranes, Las Vegas relied on artesian wells.
Because of the geology beneath the Earth’s surface, underground
pressure and physics, these coveted artesian wells sprayed
water into the air without pumping. In Las Vegas, such wells
offered an early water supply. These were the free-flowing and
freewheeling days of Las Vegas water.
Two massive local water purification projects set to begin
construction within the next 18 months have received up to $182
million from water wholesaler Metropolitan Water District of
Southern California. The regional water agency funds are headed
for a $700 million groundwater replenishment project in the San
Fernando Valley and a $364 million water purification project
in the Westlake Village area. Contractors have been selected
for both projects, which are set to begin construction within
the next 18 months. “For decades, investments in local projects
have helped strengthen Southern California’s resiliency by
reducing demands for imported water supplies and decreasing the
burden on our system,” said Nancy Sutley, Metropolitan board’s
vice chair of climate action.
As the California State Water Resources Control board meets at
the California Environmental Protection Agency Headquarters for
three days of discussion on its Bay-Delta Water Quality Control
Plan Solano County water officials are there to speak in
opposition to a course of action that could see the county’s
water allocation from Lake Berryessa cut by 75 percent. Chris
Lee and Alex Rabidoux of the Solano County Water Agency
presented information regarding the growth of salmon
populations in Putah Creek in recent years. The state has
claimed that diminished river flows in these areas are harming
fish habitats and are ecologically detrimental to the water
system as a whole, but SCWA argues that Putah Creek is already
a standout example of salmon repopulation.
Increased water allocations from systems that move water from
northern to southern California were met with disappointment
and frustration from contractors. Both the Department of Water
Resources and Bureau of Reclamation increased allocations this
week to 40% of contracted amounts, going up 10% and 5%,
respectively. With nearly all the state’s reservoirs filled to
above average levels, the increases were seen as stingy, at
best. “This allocation increase is incredibly disappointing and
should be much higher,” said Kern County Water Agency Board of
Directors President Ted Page in a press release. … The
presence of the fish “triggered state and federal regulations”
that put an automatic crimp on pumping, the release states.
Page objected to that sort of snap regulatory reaction saying
the restrictions are “based on outdated fish population
estimating tools.”

One of the most terrifying features of the climate crisis is
how it jeopardizes our access to water, without which we cannot
live. Some two billion people lack safe drinking water, while
about almost two thirds of the human population suffers water
scarcity for some part of the year. This in turn imperils food
security, since agriculture is impossible without
water. As climate change exacerbates water shortages,
water profiteering is making the problem even worse. The
barbaric capitalist insistence on treating water as a commodity
incentivizes scarcity and hoarding, as well as imposing ever
more extreme levels of thirst upon the world’s poor. -Written by Liza Featherstone, the author

The city of Sanger has allowed its largest private employer,
Pitman Family Farms, a years-long delay in settling $1 million
in payments after the city failed for years to collect money
tied to the company’s increased water use. Pitman Family Farms
poultry processor, known for its line of high-end chickens sold
under the brand Mary’s Chicken, has steadily grown in recent
years. The family-owned company established its plant in Sanger
in 2002 and is today the second largest employer in the city
behind the public school district. As the company has grown its
business – including several plant expansions over the years
from a one-story to a four-story processing plant – its use of
city water has increased. This growth has had an impact on the
city’s infrastructure, but the city wasn’t properly charging
the company for its water use, city records show.
Prosecutors have accused Dennis Falaschi, 77, a gregarious
local irrigation official [with the Panoche Water District], of
masterminding the theft of more than $25 million worth of water
out of a federal canal over the course of two decades and
selling it to farmers and other local water districts.
According to the allegations, proceeds that should have gone to
the federal government instead were used to benefit Falaschi,
his water district and a small group of co-conspirators, much
of it funneled into exorbitant salaries and lavish fringe
benefits. … Some farmers who relied on Falaschi and his
irrigation district were outraged — at the government. They see
him as the Robin Hood of irrigation. … For more than a
year, Falaschi maintained his innocence, insisting there had
been no theft. Then this spring, his attorneys filed paperwork
that said he was prepared to change his plea. Exactly what he
will plead guilty to remains unclear.
Colorado voters may be asked to let more money flow to water

A water transfer from a small western Arizona town to a growing
East Valley community has some observers concerned. About a
decade ago, a company called Greenstone bought nearly 500 acres
of land in the town of Cibola, in La Paz County. But, a few
years later, Greenstone sold the water rights for that farmland
to Queen Creek. In the process, the company made about $14
million in profit. Since then, La Paz and two other Arizona
counties have sued the U.S. Bureau of Reclamation, arguing the
agency didn’t consider the long-term implications when it
approved the deal. A judge this year sided with those counties,
and told the bureau to essentially redo its environmental
assessment of the arrangement.
The Sacramento-San Joaquin River Delta faces significant
challenges affecting the health of its waterways and ecosystem,
and stewards say state agencies must accelerate efforts to
prepare for the impacts of climate change and a growing urban

affordable uses of sinking land for sustainable farming.
Long-term weather models are hinting a wet storm could sweep
California in early May, but forecasters warn that people
shouldn’t arrange their plans around this potential system just
yet. On Tuesday, the National Weather Service’s Weather
Prediction Center told SFGATE that some models show the storm
could generally bring a chance of 0.5 to 1 inch of rain across
the entire state. An inch of rain is not a big deal in the
winter, but in May, it’s a little less typical.
… Weather models show the storm potentially arriving May
4, with rain chances continuing into Monday, May 6. Oravec

Conservationists lost an appeal to the Ninth Circuit on
Wednesday as they attempted to force the federal government to
reconsider climate change studies in managing the Glen Canyon
Dam and Colorado River. Save the Colorado, Living River and the
Center for Biological Diversity initially asked the U.S.
Department of the Interior to consider emerging climate science
and the severe potential of climate change in updating its
management plan in 2016 for the Glen Canyon Dam on Lake Powell,
which has a water level 3,564 feet above sea level.
… [The judges] concluded that the Interior did not
violate environmental law when developing its 20-year plan for
managing water releases from the dam or the plan’s accompanying
environmental analysis.
Several environmental groups asked San Francisco on Tuesday to
reduce its diversion of Tuolumne River water. They said chinook
salmon and other wildlife suffer from the current operations,
especially the river stretch in and near Modesto. At a meeting
of the San Francisco Public Utilities Commission, the groups
urged more conservation and wastewater recycling. The agency
responded that these “single-issue activists” do not understand
the city’s needs. San Francisco secured rights in 1913 to about
an eighth of the Tuolumne, which arises at about 13,000 feet in
Yosemite National Park. Most of the water diversion is at Hetch
Hetchy Reservoir, built just inside the western park boundary
to the dismay of early preservationists.
The Bureau of Reclamation announced Wednesday that
south-of-Delta water contractors are having their water
allocation increase from 35 percent to 40 percent of their
contracted amount. That five percent increase was
“incredibly disappointingly low” for Westlands Water
District. The big picture: South-of-Delta contractors
were initially allocated 15 percent of their contracted total
in February, but that number was boosted to 35 percent in
March. Farmers were hopeful that California’s above
average snowpack would result in a greater boost, considering
the state has had a good start to the year with precipitation.
When Californians voted for Proposition 1 in 2014, they had

Arizona Democrats are looking to capture voters mindful of one
resource that is sparse in the desert state: water. As
political battles over abortion and the southern border hit
close to home for some Arizonans, record-setting
high-temperature summers and droughts worry many. Democrats
look to rein in rural voters who have turned on the party by
framing water as a “life or death” matter going into the 2024
elections. … In tandem, Mayes and Gov. Katie Hobbs
(D-AZ) have cracked down on controversial farms that
had unlimited access to the state’s limited groundwater
supply. Last year, the pair ended a contract with a Saudi
Arabian company, Fondomonte, that grew alfalfa in Arizona and
then shipped the hay back to the Middle East. Under the
contract from former Republican Gov. Doug Ducey, the company
was given unlimited access to groundwater in Arizona.
With runoff from this year’s snow and rain boosting the levels
of California’s reservoirs, state water managers on Tuesday
announced plans to increase deliveries of supplies from the
State Water Project to 40% of full allotments, up from 30% last
month. The increased allocation, which had been widely
expected, means that suppliers serving 27 million Californians,
as well as some farming areas, will have substantially more
water available to use and store this year. But the Department
of Water Resources also said officials have had to limit
pumping from the Sacramento-San Joaquin River Delta this year
because of environmental protections for native fish.
With San Diego more than half done with the first phase of its
Pure Water sewage recycling system, city officials say they are
considering major changes to how they will handle the second,
larger phase. … Plans for the second phase, which were
mostly put in place 13 years ago, could change significantly
based on new state regulations and new information about how
much purified water the city is projected to need. … But
the city could abandon a plan to build the phase two
purification plant on a vacant 17-acre site in Mission Valley,
and plans to store purified water from that plant in either
Lake Murray or the San Vicente Reservoir.

Atmospheric river storms are like punches in a boxing match. A
flurry of weak ones are OK. But it’s best to avoid the big
knockout blows. That’s exactly what happened in California this
winter. Scientists say that from Oct. 1 to April 1, the state
actually received more atmospheric rivers, the famous
moisture-laden meteorological events that are critical to the
water supply, than it did last year — 44 this winter compared
to 31 last winter. But the intensity made all the difference.
Statewide, California had just 2 strong atmospheric rivers this
winter, compared with 7 last year. Many of the biggest this
winter hit Washington and Oregon instead. The result was, for
the most part, a remarkably, blissfully average rainy season
for California. 3 were moderate and 7 were strong. This year,
26 were weak, 16 were moderate and 2 were strong.
Already fuller this year than it was at this time a year ago,
Lake Shasta continues to fill, creeping toward the top ―
sometimes rising just inches a day. But by early May, the lake
level is expected to stop rising and the long draw-down of the
lake will begin again and continue through the summer. The lake
is expected to reach about 5 feet from full sometime in early
May, according to Michael Burke, a spokesman for the U.S.
Bureau of Reclamation, which operates Shasta Dam. … Two
years ago, conditions at the lake were dire, with the water
level down to historically low levels. … But with the
lake fuller this year, many water agencies are receiving their
full allotment of water from the bureau.
The mainstream media continues its obsession with the amount of
water that goes to producing alfalfa and other important forage
crops in the West. The Colorado River right now is
understandably a favorite topic of environmental journalists,
as state, federal and tribal decision-makers are scrambling to
negotiate a long-term river operating agreement to replace the
current one that expires in 2026. Those arguments were teed up
again last month when the Los Angeles Times broadcast a recent
study showing that agriculture is the “dominant” user of
Colorado River water, “about three times the combined usage of
all the cities that depend on the river”. Unfortunately, not a
single Colorado River farmer or water manager was mentioned in
that story. -Written by Dan Keppen, executive director of the Family
Farm Alliance.
The current water year, which began Oct. 1, has been wetter
than usual, with the Russian River watershed accumulating 119%
of the yearly average rainfall, totaling 49.38 inches since
October. In the past, we might have celebrated our good fortune
and watched lake levels rise only to watch much of it sent
downriver to the Pacific Ocean as reservoirs reached an
inflexible upper threshold. Today, we get to continue enjoying
that ample rainfall long after summer sunshine arrives. Grant
Davis With almost a decade of data under its belt, the Russian
River Forecast-Informed Reservoir Operations program has been
making great strides by demonstrating the viability of this
strategy to operate reservoirs more effectively using modern
technology and forecasting. -Written by Grant Davis, general manager of Sonoma
Water.
Lake Powell could reach a four-year high this spring and summer
as snowmelt supplements the reservoir’s water levels. Lake Mead
in Nevada and Arizona and Lake Powell in Utah and Arizona have
suffered from a regional drought for years, and excessive water
usage is slowly depleting the Colorado River faster than
natural weather patterns can fill it. An above-average snowfall
and excessive precipitation last spring and this winter have
bolstered the water levels at Lake Powell and Lake Mead, and
new data from the U.S. Bureau of Reclamation revealed that the
nation’s second-largest reservoir could rise by up to 50 feet
by mid-summer.
In an effort to protect more than 5 million Californians from a
cancer-causing contaminant, state regulators today set a new
standard that is expected to increase the cost of water for
many people throughout the state. The State Water Resources
Control Board unanimously approved the nation’s first drinking
water standard for hexavalent chromium, which is found
naturally in some California groundwater as well as water
contaminated by industries. Now water suppliers will be forced
to install costly treatment to limit the chemical in water to
no more than 10 parts per billion — equivalent to about 10
drops in an Olympic-sized swimming pool.
San Francisco has been giving Seattle a run for its money on
the precipitation front. Since Jan. 1, nearly 18 inches of
rain has accumulated in San Francisco. Meanwhile, Seattle sits
at just 13 inches. This year is unusual. San Francisco
has been rainier than Seattle in just 16 of the past 50 years
through mid-April. In a normal year, San Francisco trails
Seattle by about 2.5 inches of precipitation on April
14. Annually, Seattle averages 16.5 inches more rainfall
than San Francisco and may still surpass San Francisco this
year. While 2024’s rainfall may seem topsy-turvy, it
fits expectations with El Niño, a global climate pattern that
has its biggest influence on West Coast storms from January
through April.
The sunlight glints off a geometric shape across the glassy
surface of a reservoir in the Golan Heights. This is a solar
array, with panels mounted on floating pontoons, and anchored
to the banks, rising and falling with the water level. The
innovation of “dual use” reservoirs — providing water storage
on the one hand, and “green” energy on the other — is just the
latest advance pioneered by the Jewish National Fund (JNF),
which manages Israel’s forests and farmland. …
California has not seen a major reservoir built since the late
1970s, but Israel built hundreds of small reservoirs from 1990
to 2010, after a water crisis in the 1970s and 1980s prompted
the government to expand the system’s capacity.
The Sonoma County Water Agency —Sonoma Water— Board of
Directors voted Tuesday to increase wholesale water rates to
address the pressing aging infrastructure needs. The adjusted
wholesale water rates are forecasted to have a modest impact on
household budgets of between $2-$3 per month, based on location
and water usage. The cities of Cotati, Petaluma, Rohnert Park,
Santa Rosa and Sonoma; the town of Windsor; and the Marin
Municipal, North Marin and Valley of the Moon water districts,
all purchase their water from Sonoma Water.
A major southern Colorado water district voted unanimously last
week to oppose an $80.4 million agricultural water purchase by
Aurora in the Arkansas Valley, saying the deal violates a 2003
agreement that prohibits the fast-growing city from taking more
water out of the valley. Aurora would lease the water back to
Arkansas Valley farmers in most years, using it periodically in
dry periods. During a special meeting April 9, the Southeastern
Colorado Water Conservancy District said it had numerous
concerns with the purchase, which is set to close this month.
Southeastern manages the federally owned Fryingpan-Arkansas
Project, which includes the Pueblo Reservoir.
Ecuador on Tuesday began to ration electricity in the country’s
main cities as a drought linked to the El Niño weather pattern
depletes reservoirs and limits output at hydroelectric plants
that produce about 75% of the nation’s power. The power cuts
were announced on Monday night by the ministry of energy, which
said in a statement that it would review its decision on
Wednesday night. … The power cuts in Ecuador come days after
dry weather forced Colombia’s capital city of Bogotá to ration
water as its reservoirs reached record lows, threatening local
supplies of tap water. In the town of La Calera, on the
outskirts of Bogotá, water trucks visited neighborhoods where
water has been scarce recently because a local stream that
supplies the town with water is drying up.
The governance of San Francisco Bay/Sacramento-San Joaquin
Delta water quality falls under the authority of the State
Water Quality Control Board. Among other duties, the Water
Board is responsible for adopting and updating the Bay-Delta
Water Quality Control Plan for the San Francisco
Bay/Sacramento-San Joaquin Delta Estuary (Bay-Delta
Plan). The Bay-Delta Plan’s purpose sets forth measures
and flow requirements to safeguard various water uses within
the watershed, including municipal, industrial, agricultural,
and ecological needs. Comprising five political appointees with
extensive powers, the Water Board plays a pivotal role in
shaping California’s water management policies. -Written by Cary Keaten, the general manager of

Shasta Lake is near its capacity for the second straight year,
but officials say there still is plenty of room left to fill.
As of Monday, California’s largest reservoir is just seven feet
from its max capacity of 1,067 feet. This marks the first time
in over a decade that Shasta Lake has remained nearly filled in
back-to-back years, according to the Bureau of Reclamation’s
Don Bader. While less than 10 feet of room may not sound like a
lot, the reservoir still has plenty of storage space.
The Bureau of Reclamation today announced the initial 2024
water supply allocations for the Klamath Project along with
$8.5 million in immediate funding for the Klamath Basin
communities to support drought resiliency and $5 million for
Klamath Basin tribes impacted by drought. In partnership with
the Klamath Project Drought Response Agency, Reclamation has
secured $8.5 million for administration of specifically
authorized drought resiliency programs targeted for project
contractors who receive a reduced water allocation. Reclamation
is announcing this funding together with an additional $5
million from separate program sources which will be disbursed
through technical assistance agreements with Klamath Basin
Tribal Nations for drought and ecosystem activities.
One of the biggest battles over Colorado River water is being
staged in one of the west’s smallest rural enclaves.Tucked into
the bends of the lower Colorado River, Cibola, Arizona, is a
community of about 200 people. … Nearly a decade ago,
Greenstone Resource Partners LLC, a private company backed by
global investors, bought almost 500 acres of agricultural land
here in Cibola. In a first-of-its-kind deal, the company
recently sold the water rights tied to the land to the town of
Queen Creek, a suburb of Phoenix, for a $14m gross profit. More
than 2,000 acre-feet of water from the Colorado River that was
once used to irrigate farmland is now flowing, through a canal
system, to the taps of homes more than 200 miles away.
California’s second wet winter in a row has left L.A’s water
supplies in good shape for at least another year, but the
inevitable return to dry conditions could once again put the
city’s residents in a precarious position. After the state’s
final snow survey of the season, officials with the Los Angeles
Department of Water and Power announced that Eastern Sierra
snowpack is measuring 103% of normal, “providing ample supplies
through the city’s most cost-efficient water supply from the
Los Angeles Aqueduct.”
Missouri lawmakers say water has almost always been plentiful
in their state, giving no reason to think twice about a concept
known as riparian rights — the idea that, if you own the land,
you have broad freedoms to use its water. But that could change
under a bill advancing quickly in a state legislature that is
normally sharply divided. The measure would largely forbid the
export of water across state lines without a permit, even
though there is no evidence that is happening on any large
scale. … lawmakers are wary of the West, and the chance that
thirsty communities facing dwindling water supplies will look
east for lakes and rivers to tap.
Even though Pacific storms have become less frequent, as is
often the case in April, a new storm is brewing and will slice
across California just in time for the weekend, bringing areas
of rain, mountain snow and much cooler air, AccuWeather
meteorologists say. … A storm over the Gulf of Alaska will
drop southward just off the coast into Friday and will swing
toward California this weekend. … A few inches to
perhaps a foot of snow may fall over the high country of the
Sierra Nevada from the weekend storm.
The majority of California’s reservoirs are above their
historic average levels following the end of two wet winters.
The state’s largest reservoirs, Shasta Lake and Lake Oroville,
were measured at a respective 118% and 122% of their averages
for early April, according to data from the California
Department of Water Resources. Folsom Lake in the Sierra Nevada
foothills exits early April at 116%. Only two reservoirs, San
Luis in western San Joaquin Valley and Castaic in Southern
California, were below average. San Luis Reservoir was at just
87% and much smaller Castaic Lake in Los Angeles County was at
92%.
In a devastating blow to California’s fishing industry, federal
fishery managers unanimously voted today to cancel all
commercial and recreational salmon fishing off the coast of
California for the second year in a row. The decision is
designed to protect California’s dwindling salmon populations
after drought and water diversions left river flows too warm
and sluggish for the state’s iconic Chinook salmon to
thrive. … Many in the fishing industry say they
support the closure, but urged state and federal officials to
do more to improve conditions in the rivers salmon rely on.
Fishing advocates and environmentalists have lambasted Gov.
Gavin Newsom’s administration for failing to prioritize
water quality and flows to protect salmon in the
vital Bay-Delta watershed.

Klamath, Modoc and Siskiyou County leaders are asking for an
“adequate water supply” on behalf of local irrigation. A news
release from Klamath Water Users Association this week said a
letter has been sent to the Bureau of Reclamation requesting
the full water allocations on behalf of Klamath Project
irrigators. The letter, sent to Reclamation Commissioner
Camille Calimlim Touton, bases the request for increase water
flows in congruence with “favorably hydrology” this year in the
Klamath Basin.
Key backup tubes inside the Glen Canyon Dam might be damaged,
potentially threatening the delivery of water to Lake Mead in
the future if water levels ever dip too low in Lake Powell,
according to a Bureau of Reclamation memo. Below 3,490 feet,
water releases from Lake Powell are wholly dependent on “river
outlet works,” which water managers now feel are not functional
and could threaten the water supply downstream. Currently, the
reservoir sits at 3,558 feet, and the latest two-year
projection places water levels above 3,560 feet until at least
February 2026. Looming threats of climate change and
evaporative losses also are complicating state negotiations for
how to allocate the shrinking Colorado River.
California is expected to experience what some meteorologists
are calling “weather whiplash” this week with a brief spell of
warm weather during the work week followed by a wet weekend
from yet another unusually cold storm. … A significant
weather shift is expected to impact the Golden State starting
Friday, with temperatures dropping as a cold storm system
approaches the area, potentially bringing rains as early as
Friday to some locations. Widespread rain is expected Saturday.
Over the past few decades, the United States has imported most
of its lithium from Chile and Argentina, but there’s one major
domestic source of the mineral—Nevada. Clayton Valley, a remote
basin in the nation’s driest state, is home to the Silver Peak
mine, where lithium is extracted in gridded ponds that turn
neon blue as they recover one of Earth’s lightest elements
through solar evaporation. … Mining operators across the
West have faced major barriers in the global race for lithium.
Mines come with large footprints that can disrupt wildlife
habitat, harm cultural sites and put pressures on communities.
On top of all that is another major challenge posing a barrier
for lithium projects in the western U.S. and Clayton Valley:
Competition for limited water supplies.
Pasadena Water and Power (PWP) has launched a new multi-year
campaign called “The Ripple Effect” aimed at promoting water
sustainability and resilience in the community. Acting General

water stewards for Pasadena and the region by participating
in the campaign. “We invite every member of our
community to embrace their role as local water stewards,” said
Reyes. “Each one of us holds a vital place in shaping
Pasadena’s water future.” About one-third of
Pasadena’s water supply comes from local groundwater, with the
remaining two-thirds imported from other sources. PWP
emphasized that understanding where the community’s water comes
from helps foster a greater appreciation for
this critical resource.
Aiming to boost the county’s water supply, the Marin Municipal
Water District is exploring the idea of connecting pipelines in
Petaluma and Cotati to its reservoirs. District staff presented
three main potential projects — narrowed from 13 — at Tuesday’s
board of directors meeting. … The pipelines would transport
water from the Russian River into Marin reservoirs. Treated
Russian River water is transported to Marin through a 9-mile
aqueduct along the Highway 101 corridor from Petaluma to North
Marin Water District in Novato. The district then sends the
water directly to the Marin Municipal Water District’s water
distribution system. Board members expressed concern over cost
estimates, which ranged between $140 million and $380 million.
… U.S. Geological Service data shows Teton Valley’s aquifer
steadily declined in recent decades as development increased
and crop watering systems became more efficient, reducing
infiltration by replacing flood irrigation with pivots and
sprinklers. In addition, the area’s transition from
agricultural valley to recreation hub has meant less acreage
being watered: farms replaced by subdivisions full of houses
with domestic wells, each one a straw guzzling from the
valley’s all-important aquifer. … Recharge has benefited
farmers and fish in western communities like Idaho’s Eastern
Snake River Plain and California’s Central Valley, and the
group believes the data shows it can work in the Teton Basin.
They hope it can. In addition to providing a bulwark against
future water shortages or legislative changes to water rights
laws, they want to do something groundbreaking: create a
market-based system to pay farmers for incidental recharge.
Lake Shasta could reach its full capacity this spring,
following a high amount of rainfall in California. The largest
reservoir in California has been steadily rising since the
beginning of March. It has gone up sharply since the start of
the year, which saw its levels at 1,012 feet, compared to its
current level on April 5 of 1,058 feet. The lake has risen by
about 19 feet since the beginning of March alone. “Shasta
Reservoir is currently 121 percent of the 15-year average and
93 percent full as of April 4. Unlike other Central Valley
Project reservoirs, Shasta is predominantly filled by rainfall
rather than snowpack runoff,” a Bureau of Reclamation
spokesperson told Newsweek. … The reservoir, located in
Shasta County, California, was in a dire situation due to
drought in 2022.
Gov. Gavin Newsom has a new sales pitch for a tunnel to move
more water south from the Sacramento-San Joaquin River Delta
that past governors have tried and failed to build for five
decades. “The Delta conveyance is an adaptation project,” he
said last week in a snowy field in the Sierra Nevada, where a
winter that started out dry eventually delivered a
just-above-average snowpack that will soon melt into the
Sacramento River and its
tributaries. … Long-skeptical Delta lawmakers
aren’t convinced by the latest rationale. “He’s searching for a
reason,” said Representative John Garamendi, a Democrat
from the western part of the Delta.

resiliency, land stewardship and fiscal responsibility.
… This marked the second year in a row with above-average
snowfall and was a huge turnaround from conditions at the
beginning of 2024, when the snowpack across the state was
barely a quarter of the historic average. … The
relationship between snowfall and climate change is not as
simple as it might first appear. Though rising temperatures
will cause some would-be snow to fall as rain, this is partly
balanced out by the fact that precipitation will become more
intense overall, since warmer air can hold more water vapor.
Some parts of Alaska and Northern Canada have
seen increases in snowfall over the last 40 years; in
these frigid locales the amount of snow is more limited by cold
weather, which decreases the amount of moisture in the air. -Written by Ned Kleiner, a scientist and catastrophe
modeler at Verisk.

Spring storms brought more snow to mountains across the Western
U.S., bringing water for struggling Lake Powell with them. The
National Weather Service Colorado Basin River Forecast Center
on Friday estimated that Lake Powell will receive 5.7 million
acre-feet of water between April and July as snow melts off the
mountains. An acre-foot is roughly enough water to sustain two
houses for a year. That volume is 89% of the normal runoff for
that time period recorded between 1991 and 2020. Facing
extreme drought and climate change since the turn of the
century, Lake Powell dropped to a historic low of 22%
full in Feb. 2023. The reservoir currently stands at
about 32% full.
Last month, the seven U.S. states that use Colorado River water
released two divergent plans for how that water should be
managed after 2026 when the current agreement expires. Their
proposals centered on operations at Lake Powell and Lake Mead,
the country’s two largest reservoirs, the levels of which are
instrumental in determining how much water each state gets. But
a coalition of environmental organizations felt that those
plans — and the discourse surrounding which states should have
to cut their water use — drowned out a crucial consideration:
the environment. So, last week, they submitted a plan of their
own. “Our plan explicitly integrates environmental values and
resources into the planning, while also trying to meet the
needs of people,” Taylor Hawes, the Colorado River Program
director for The Nature Conservancy, said.
On April 2, 2024, the California Department of Water Resources
(DWR) released the California Water Plan Update 2023 (CWP 2023
Update). DWR’s press release dubs the plan “A Roadmap to Water
Management and Infrastructure for a Water Resilient Future.”
Resiliency is one of the key focuses for the CWP 2023 Update,
as its chapter on objectives is entitled the “Roadmap to
Resilience.” The plan is focused on the vision that “All
Californians benefit from water resources that are sustainable,
resilient to climate change, and managed to achieve shared
values and connections to our communities and the environment.”
On April 3, a coalition of fishing and conservation
groups said the state and federal water agencies must
“take immediate action” to stop the unauthorized killing of
thousands of Chinook Salmon and Steelhead at the State and
Federal water export pumps in the Sacramento-San Joaquin River
Delta, The State Water Project (SWP) and Central Valley
Project (CVP) Delta “death pumps” have been the
biggest killers of salmon, steelhead, Sacramento
splittail and other fish species in California for many
decades. … The coalition said this is the second
time in 2024 the coalition has responded to an increase in
killing of legally protected fish at the pumps of the State
Water Project and the Central Valley Project (Projects or Water
Projects).
California has more than 1,000 thousand miles of coastline and
the water in the Pacific Ocean presents an opportunity for more
fresh water in the state. Unlocking the opportunity takes time,
money and resources, and some experts say it’s not for
everyone. … The massive system California has in place
now is one of the most complicated, robust and successful
systems ever created. That system has more recently
incorporated the ocean. Desalination is being put to the test
in coastal areas up and down the state. The process takes salt
out of ocean water and turns it into fresh water for people.
State officials, as well as private partners, focus on these
areas as the best fit for this water supply.
Water access in California has seen growing scrutiny as the
climate shifts from more extreme dry to wet swings. This
results in increasing year-to-year uncertainty for both
commercial and residential water availability. One area getting
more attention from an ethical and practical application is the
system of water rights, which first took shape in the late
1800s.
Winter brought just average rain and snow to Stanislaus
County’s main watershed, but most farmers will get abundant
supplies. That’s because reservoirs continue to hold much of
the runoff from last year’s truly wet conditions. Only in parts
of the West Side will water be limited. The storms also boosted
groundwater, which is part of the supply in many places. City
residents, too, can expect no cutbacks, but they still have to
follow rules against outdoor watering in the afternoon. Too
much demand on a hot summer day can tax the distribution
system.
Yesterday, Gov. Gavin Newsom surveyed the Sierra snowpack and
outlined a new state water plan focused on climate change.

It was an average year for Colorado’s snowpack — and that’s
great news. The statewide snowpack sat at 109% of the
30-year median on Wednesday, just a few days shy of the normal
peak of snowpack for the state. Every major river basin in the
state also recorded above-median snowpack, reducing the risk of
large, uncontrollable wildfires and boosting the state’s water
supplies. Despite a slow start to the snow season, large
storms in February and March boosted the amount of water that
will become available as mountain snow melts. The statewide
snowpack had lagged behind the median until early March.
Los Angeles Department of Water & Power (DWP) and Mono Lake
Committee staff met this morning at the shore of Mono Lake to
conduct the annual joint reading of the surface elevation of
Mono Lake. The consensus is that the lake stands at 6,383.70
feet above mean sea level which means that Mono Lake is only
halfway to the 6,392-foot elevation level mandated by the
California State Water Resources Control Board 30 years ago to
resolve ecological, wildlife, economic, Tribal, public trust,
and air quality harms caused by the lowering of Mono
Lake. Today’s lake level triggers an important choice for
DWP: Will the Department choose a nearly fourfold increase in
diversions (16,000 acre-feet), or will it choose to leave
exports unchanged (4,500 acre-feet) and preserve the lake level
gains of the record-wet winter of 2023?
In December 2018 the State Water Resources Control Board (State
Board) adopted updates to the Bay-Delta Plan (Plan) in
accordance with its obligations under the Porter-Cologne Act.
The updated Plan included flow objectives intended to restore
and protect Chinook salmon and Central Valley steelhead in the
lower San Joaquin River and its tributaries. Twelve lawsuits
and 116 claims were filed challenging the State Board’s updated
Plan. On March 15, 2024, Sacramento County Superior Court Judge
Stephen Acquisto rejected all lawsuits and claims. To some
degree the court’s decision is a win for California’s
fisheries, but the decision also affirmed the discretionary
right of the State Board to keep less water in rivers than
needed to restore fisheries and aquatic ecosystems.
The start of April means that California’s rainy season is
coming to an end. Things are looking pretty good this year, but
there are some caveats. The snowpack across the Sierra Nevada
and the Colorado River Basin — both critical stores of water —
is hovering slightly above average, though it’s nowhere near
what we saw last winter. … It’s looking unlikely, as our
reservoirs are quite full and we’ve had a good showing of
snow. “We pulled back on restrictions last year, however,
we’re telling people to use their common sense,” said Adel
Hagekhalil, CEO of the Metropolitan Water District of Southern
California. The public agency will neither be drawing from
or putting water into storage, though that’ll change if the
allocation increases. According to Hagekhalil, the MWD has
enough water to help Southern California get through the next
three years.
California’s water resources look promising thanks to a string
of cold, wet storms since January, but the state’s leaders are
eyeing how significant the payout from those storms will be for
future years. State officials and experts from the University
of California, Berkeley’s Central Sierra Snow Laboratory say
the Golden State’s water and snow outlook is looking good this
spring, despite a dry start to the water year. The milestone
snowpack survey of the year, conducted Tuesday at Phillips
Station in El Dorado County, found a snowpack measuring 64
inches and a snow water equivalent — water contained in the
snowpack — of 27.5 inches. … All state watersheds
have significantly improved in water storage since Feb. 20,
with all sitting at 90% or higher. The State Water Project also
increased its forecast allocation of water supplies to 30%.
For a place where nature didn’t intend lettuce to grow, the
southwest corner of Arizona has built a spectacular record as
“America’s salad bowl.” Thanks to copious irrigation and
decades of public investment, Yuma and the bordering Imperial
Valley of California supply as much as 90 percent of the
nation’s salad greens during the winter, making the area
pivotal to the debate over the future of American agriculture
in an era of oppressive weather made worse by the changing
climate.
Groundwater in Arizona belongs to all of us. It is a public
resource and sensible management of it is vital to our shared
future. But instead of fulfilling their obligation to
protect this finite and diminishing water supply, Arizona’s
Republican legislators have introduced dozens of bills at the
statehouse aimed at enriching residential developers and
corporate farmers who want to expand their groundwater
use. Many of these bills are advancing and will end up on
the governor’s desk. One intent of these bills is to
weaken the state’s assured water supply requirement for
development in urban areas. This crucial consumer protection
prevents the sale of subdivision lots that lack a 100-year
water supply, thereby assuring our desert state’s
longevity. -Written by Kathleen Ferris, a Phoenix water

The Biden-Harris administration is redoubling its efforts to
improve cybersecurity for the nation’s water systems. In March,
the U.S. Environmental Protection Agency (EPA) and the White
House issued a dire warning to state governors alerting them of
the need to protect water and wastewater systems from ongoing
cybersecurity threats and requested that the states provide
plans to decrease the risk of attacks on water and wastewater
systems in their state. … While the letter focused on
the national need for investment in water infrastructure,
California’s water systems are in particularly dire need for
upgrades. The EPA has previously estimated that California
needs about $51 billion in improvements to its water
infrastructure.
With California snowpack and reservoirs at above-average levels
following two wet winters, Gov. Gavin Newsom stood on a snowy
field near Lake Tahoe on Tuesday and urged the state to do much
more to make its water supplies resilient to the extreme
droughts and flooding that come with climate change. … The
governor presented a new water plan that lays out priorities
for changing how the state captures, stores and moves water,
including efforts to replenish groundwater, recycle wastewater
and restore the natural ecosystems of watersheds. Newsom said
his administration is focusing on infrastructure projects such
as building the Sites Reservoir — the first new major reservoir
in decades — and he vowed to move ahead with the proposed Delta

past month and a half and snowpack levels are 11% above normal
on April 1 — the date that snow normally peaks as warmer
weather begins to set in. … Two consecutive years above
normal snowpack levels is bucking the trend reported in a
July 2023 study that showed runoff has declined 10.3% over
the past 140 years because of increasing hotter
temperatures. Last year’s wet winter helped refill Lake
Mead and Lake Powell, the nation’s two largest reservoirs. But
they are still low. Lake Mead is currently at 37% of capacity,
and Lake Powell is at 33%.
The Imperial Irrigation District announced in a recent press
report that it has been awarded $7 million in grant funds from
the Department of the Interior in support of the district’s
proposed Upstream Operational Reservoir Project, which would be
the largest reservoir ever constructed in the Imperial Valley
during IID’s 113-year history as an irrigation district. The
announcement was recently made by the Interior Department, with
funds coming from the Bipartisan Infrastructure Law to increase
water supply reliability. This latest grant award to IID is in
addition to a $9.5 million grant previously awarded to the
district for a total of $16.5 million in federal funding for
the Upstream Operational Reservoir Project.
A coalition of environmental groups is proposing a new set of
rules for managing the Colorado River after 2026, when the
current guidelines expire. … The “Cooperative
Conservation Alternative,” as dubbed by the environmental
proposal’s authors, offers a series of ideas on how to make
sure decisions about the water supply for people and businesses
don’t leave the environment behind. The first idea outlined in
the proposal is the implementation of a new way of measuring
how much water is stored in reservoirs along the Colorado
River, with water releases adjusted accordingly.
… In a matter of weeks, a succession of powerful storms
flipped the script, dumping a stream of record-setting, intense
rainfall across California, much of it on the state’s
southwestern region. That wet pattern has continued as winter
has given way to spring, with this past weekend’s storm dumping
up to 4 inches of rain in some areas — pushing Los Angeles to a
new two-year rain total not seen since the late 1800s and
forestalling any hope for a quick end to the rainy season.
… With more than 30 million acre-feet of water in
storage, the state’s reservoirs are at 116% of their
historical average.
Some Bee colleagues and I recently took a tour of Westlands
Water District — the nation’s largest agricultural water
district, located on the western edges of Fresno and Kings
counties. … But facing the twin challenges of drought
and new state restrictions on groundwater use, Westlands
farmers and counterparts throughout the San Joaquin Valley are
considering a new money maker for their land: solar power.
As winter conditions wind down, the beginning of April is
always the most important time for California’s water managers
to take stock of how much snow has fallen in the Sierra
Nevada. This year, something unusual happened. After years
of extreme drought and several very wet flood years, the Sierra
snowpack, the source of one-third of the state’s water supply,
is shockingly average this year: 104% of normal on
Friday. And more is on the way.
With chronic water shortages afflicting the Colorado River,
discussions about how to cut usage have increasingly focused on
a thirsty crop that consumes an especially large share of the
river’s water: hay that is grown to feed cattle and produce
beef and dairy products. In a new study, researchers found that
alfalfa and other cattle-feed crops consume 46% of the water
that is diverted from the river, accounting for nearly
two-thirds of agricultural water use. The research also shows
that agriculture is the dominant user of Colorado River water,
accounting for 74% of the water that is diverted — about three
times the combined usage of all the cities that depend on the
river. The study presents the most detailed analysis of its
kind to date, including extensive data on where the river’s
water goes across seven Western states and northern Mexico.
… Over the next several years, Pacific Gas and Electric Co.,
the current owner of the Potter Valley Project, is planning to
retire the hydroelectric plant and remove two dams on the Eel
River that provide water for the facility. With power
production shut down, tunneling water into the Russian River
won’t be necessary. … The Potter Valley Project provides a
portion of the water supply for large swaths of Mendocino and
Sonoma counties. … Scores of vineyards here are tethered
to water rights that are subject to restriction when river
levels drop. During the recent drought, hundreds of
water-rights holders were forced to stop pumping — a
scenario many believe was a preview of a future where the Eel
River doesn’t continue to supplement the Russian.

The Layperson’s Guide to the Colorado River Basin introduces the
1,450-mile river that sustains 40 million people and millions of
acres of farmland spanning seven states and parts of northern
Mexico.
The 28-page primer explains how the river’s water is shared and
managed as the Southwest transitions to a hotter and drier
climate.
Moab is a growing town of 5,300 that up to 5 million people
visit each year to hike nearby Arches and Canyonlands national
parks, ride mountain bikes and all-terrain vehicles, or raft
the Colorado River. Like any western resort town, it
desperately needs affordable housing. What locals say it
doesn’t need is a high-end development on a sandbar projecting
into the Colorado River, where groves of cottonwoods, willows
and hackberries flourish. “Delusional,” shameful” or
“outrageous” is what many locals call this Kane Creek
Preservation and Development project. - Written by Mary Moran, a contributor to Writers on
the Range
After more than two decades of
drought, water utilities serving the largest urban regions in the
arid Southwest are embracing a drought-proof source of drinking
water long considered a supply of last resort: purified sewage.
Water supplies have tightened to the point that Phoenix and the
water supplier for 19 million Southern California residents are
racing to adopt an expensive technology called “direct potable
reuse” or “advanced purification” to reduce their reliance on
imported water from the dwindling Colorado River.
The climate-driven shrinking of the
Colorado River is expanding the influence of Native American
tribes over how the river’s flows are divided among cities, farms
and reservations across the Southwest.
The tribes are seeing the value of their largely unused river
water entitlements rise as the Colorado dwindles, and they are
gaining seats they’ve never had at the water bargaining table as
government agencies try to redress a legacy of exclusion.
A new but little-known change in
California law designating aquifers as “natural infrastructure”
promises to unleash a flood of public funding for projects that
increase the state’s supply of groundwater.
The change is buried in a sweeping state budget-related law,
enacted in July, that also makes it easier for property owners
and water managers to divert floodwater for storage underground.
A new underground mapping technology
that reveals the best spots for storing surplus water in
California’s Central Valley is providing a big boost to the
state’s most groundwater-dependent communities.
The maps provided by the California Department of Water Resources
for the first time pinpoint paleo valleys and similar prime
underground storage zones traditionally found with some guesswork
by drilling exploratory wells and other more time-consuming
manual methods. The new maps are drawn from data on the
composition of underlying rock and soil gathered by low-flying
helicopters towing giant magnets.
The unique peeks below ground are saving water agencies’
resources and allowing them to accurately devise ways to capture
water from extreme storms and soak or inject the surplus
underground for use during the next drought.
“Understanding where you’re putting and taking water from really
helps, versus trying to make multimillion-dollar decisions based
on a thumb and which way the wind is blowing,” said Aaron Fukuda,
general manager of the Tulare Irrigation District, an early
adopter of the airborne electromagnetic or
AEM technology in California.
Much of California’s water supply
originates in the Sierra Nevada, making it dependent on the
health of forests. But those forests are suffering from
widespread tree mortality and other ecosystem degradation
resulting mostly from the growing frequency and severity
of droughts and wildfires.
The states of the Lower Colorado
River Basin have traditionally played an oversized role in
tapping the lifeline that supplies 40 million people in the West.
California, Nevada and Arizona were quicker to build major canals
and dams and negotiated a landmark deal that requires the Upper
Basin to send predictable flows through the Grand Canyon, even
during dry years.
But with the federal government threatening unprecedented water
cuts amid decades of drought and declining reservoirs, the Upper
Basin states of Wyoming, Utah, Colorado and New Mexico are
muscling up to protect their shares of an overallocated river
whose average flows in the Upper Basin have already dropped
20 percent over the last century.
They have formed new agencies to better monitor their interests,
moved influential Colorado River veterans into top negotiating
posts and improved their relationships with Native American
tribes that also hold substantial claims to the river.
This tour explored the lower Colorado River firsthand where virtually every drop of the river is allocated, yet demand is growing from myriad sources — increasing population, declining habitat, drought and climate change.
The 1,450-mile river is a lifeline to some 40 million people in the Southwest across seven states, 30 tribal nations and Mexico. How the Lower Basin states – Arizona, California and Nevada – use and manage this water to meet agricultural, urban, environmental and industrial needs was the focus of this tour.

It was exactly the sort of deluge
California groundwater agencies have been counting on to
replenish their overworked aquifers.
The start of 2023 brought a parade of torrential Pacific storms
to bone dry California. Snow piled up across the Sierra Nevada at
a near-record pace while runoff from the foothills gushed into
the Central Valley, swelling rivers over their banks and filling
seasonal creeks for the first time in half a decade.
Suddenly, water managers and farmers toiling in one of the
state’s most groundwater-depleted regions had an opportunity to
capture stormwater and bank it underground. Enterprising agencies
diverted water from rushing rivers and creeks into manmade
recharge basins or intentionally flooded orchards and farmland.
Others snagged temporary permits from the state to pull from
streams they ordinarily couldn’t touch.
This special Foundation water tour journeyed along the Eastern Sierra from the Truckee River to Mono Lake, through the Owens Valley and into the Mojave Desert to explore a major source of water for Southern California, this year’s snowpack and challenges for towns, farms and the environment.
Growing up in the shadow of the
Rocky Mountains, Andrew Schwartz never missed an opportunity to
play in – or study – a Colorado snowstorm. During major
blizzards, he would traipse out into the icy wind and heavy
drifts of snow pretending to be a scientist researching in
Antarctica.
Decades later, still armed with an obsession for extreme weather,
Schwartz has landed in one of the snowiest places in the West,
leading a research lab whose mission is to give California water
managers instant information on the depth and quality of snow
draping the slopes of the Sierra Nevada.
When the Colorado River Compact was
signed 100 years ago, the negotiators for seven Western states
bet that the river they were dividing would have ample water to
meet everyone’s needs – even those not seated around the table.
A century later, it’s clear the water they bet on is not there.
More than two decades of drought, lake evaporation and overuse of
water have nearly drained the river’s two anchor reservoirs, Lake
Powell on the Arizona-Utah border and Lake Mead near Las Vegas.
Climate change is rendering the basin drier, shrinking spring
runoff that’s vital for river flows, farms, tribes and cities
across the basin – and essential for refilling reservoirs.
The states that endorsed the Colorado River Compact in 1922 – and
the tribes and nation of Mexico that were excluded from the table
– are now straining to find, and perhaps more importantly accept,
solutions on a river that may offer just half of the water that
the Compact assumed would be available. And not only are
solutions not coming easily, the relationships essential for
compromise are getting more frayed.
This tour explored the Sacramento River and its tributaries through a scenic landscape while learning about the issues associated with a key source for the state’s water supply.

The three-year span, 2019 to 2022, was officially the driest ever
statewide going back to 1895 when modern records began in
California. But that most recent period of overall drought
also saw big swings from very wet to very dry stretches such
as the 2021-2022 water year that went from a relatively
wet Oct.-Dec. beginning to the driest Jan.-March period in the
state’s history.

With 25 years of experience working
on the Colorado River, Chuck Cullom is used to responding to
myriad challenges that arise on the vital lifeline that seven
states, more than two dozen tribes and the country of Mexico
depend on for water. But this summer problems on the
drought-stressed river are piling up at a dizzying pace:
Reservoirs plummeting to record low levels, whether Hoover Dam
and Glen Canyon Dam can continue to release water and produce
hydropower, unprecedented water cuts and predatory smallmouth
bass threatening native fish species in the Grand Canyon.
“Holy buckets, Batman!,” said Cullom, executive director of the
Upper Colorado River Commission. “I mean, it’s just on and on and
on.”
A pilot program in the Salinas Valley run remotely out of Los Angeles is offering a test case for how California could provide clean drinking water for isolated rural communities plagued by contaminated groundwater that lack the financial means or expertise to connect to a larger water system.
As water interests in the Colorado
River Basin prepare to negotiate a new set of operating
guidelines for the drought-stressed river, Amelia Flores wants
her Colorado River Indian Tribes (CRIT) to be involved in the
discussion. And she wants CRIT seated at the negotiating table
with something invaluable to offer on a river facing steep cuts
in use: its surplus water.
CRIT, whose reservation lands in California and Arizona are
bisected by the Colorado River, has some of the most senior water
rights on the river. But a federal law enacted in the late 1700s,
decades before any southwestern state was established, prevents
most tribes from sending any of its water off its reservation.
The restrictions mean CRIT, which holds the rights to nearly a
quarter of the entire state of Arizona’s yearly allotment of
river water, is missing out on financial gain and the chance to
help its river partners.
Managers of California’s most
overdrawn aquifers were given a monumental task under the state’s
landmark Sustainable Groundwater Management Act: Craft viable,
detailed plans on a 20-year timeline to bring their beleaguered
basins into balance. It was a task that required more than 250
newly formed local groundwater agencies – many of them in the
drought-stressed San Joaquin Valley – to set up shop, gather
data, hear from the public and collaborate with neighbors on
multiple complex plans, often covering just portions of a
groundwater basin.

This tour ventured through California’s Central Valley, known as the nation’s breadbasket thanks to an imported supply of surface water and local groundwater. Covering about 20,000 square miles through the heart of the state, the valley provides 25 percent of the nation’s food, including 40 percent of all fruits, nuts and vegetables consumed throughout the country.
Climate scientist Brad Udall calls
himself the skunk in the room when it comes to the Colorado
River. Armed with a deck of PowerPoint slides and charts that
highlight the Colorado River’s worsening math, the Colorado State
University scientist offers a grim assessment of the river’s
future: Runoff from the river’s headwaters is declining, less
water is flowing into Lake Powell – the key reservoir near the
Arizona-Utah border – and at the same time, more water is being
released from the reservoir than it can sustainably provide.

For more than 20 years, Tanya
Trujillo has been immersed in the many challenges of the Colorado
River, the drought-stressed lifeline for 40 million people from
Denver to Los Angeles and the source of irrigation water for more
than 5 million acres of winter lettuce, supermarket melons and
other crops.
Trujillo has experience working in both the Upper and Lower
Basins of the Colorado River, basins that split the river’s water
evenly but are sometimes at odds with each other. She was a
lawyer for the state of New Mexico, one of four states in the
Upper Colorado River Basin, when key operating guidelines for
sharing shortages on the river were negotiated in 2007. She later
worked as executive director for the Colorado River Board of
California, exposing her to the different perspectives and
challenges facing California and the other states in the river’s
Lower Basin.
This tour guided participants on a virtual exploration of the Sacramento River and its tributaries and 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.
This tour guided participants on a virtual journey deep into California’s most crucial water and ecological resource – the Sacramento-San Joaquin Delta. The 720,000-acre network of islands and canals support the state’s two major water systems – the State Water Project and the Central Valley Project. The Delta and the connecting San Francisco Bay form the largest freshwater tidal estuary of its kind on the West coast.
Las Vegas, known for its searing summertime heat and glitzy casino fountains, is projected to get even hotter in the coming years as climate change intensifies. As temperatures rise, possibly as much as 10 degrees by end of the century, according to some models, water demand for the desert community is expected to spike. That is not good news in a fast-growing region that depends largely on a limited supply of water from an already drought-stressed Colorado River.
On average, more than 60 percent of
California’s developed water supply originates in the Sierra
Nevada and the southern spur of the Cascade Range. Our water
supply is largely dependent on the health of our Sierra forests,
which are suffering from ecosystem degradation, drought,
wildfires and widespread tree mortality.
This tour ventured into the Sierra to examine water issues
that happen upstream but have dramatic impacts downstream and
throughout the state.
When you oversee the largest
supplier of treated water in the United States, you tend to think
big.
Jeff Kightlinger, general manager of the Metropolitan Water
District of Southern California for the last 15 years, has
focused on diversifying his agency’s water supply and building
security through investment. That means looking beyond MWD’s
borders to ensure the reliable delivery of water to two-thirds of
California’s population.
As California slowly emerges from
the depths of the COVID-19 pandemic, one remnant left behind by
the statewide lockdown offers a sobering reminder of the economic
challenges still ahead for millions of the state’s residents and
the water agencies that serve them – a mountain of water debt.
Water affordability concerns, long an issue in a state where
millions of people struggle to make ends meet, jumped into
overdrive last year as the pandemic wrenched the economy. Jobs
were lost and household finances were upended. Even with federal
stimulus aid and unemployment checks, bills fell by the wayside.
As California’s seasons become
warmer and drier, state officials are pondering whether the water
rights permitting system needs revising to better reflect the
reality of climate change’s effect on the timing and volume of
the state’s water supply.
A report by the State Water Resources Control Board recommends
that new water rights permits be tailored to California’s
increasingly volatile hydrology and be adaptable enough to ensure
water exists to meet an applicant’s demand. And it warns
that the increasingly whiplash nature of California’s changing
climate could require existing rights holders to curtail
diversions more often and in more watersheds — or open
opportunities to grab more water in climate-induced floods.
This beautifully illustrated 24×36-inch poster, suitable for
framing and display in any office or classroom, highlights the
Sacramento-San Joaquin River Delta, its place as a center of
farming, its importance as an ecological resource and its
vital role in California’s water supply system.
The text, photos and graphics explain issues related to land
subsidence, levees and flooding, urbanization, farming, fish and
wildlife protection. An inset map illustrates the tidal action
that increases the salinity of the Delta’s waterways.
A government agency that controls much of California’s water
supply released its initial allocation for 2021, and the
numbers reinforced fears that the state is falling into another
drought. The U.S. Bureau of Reclamation said Tuesday that most
of the water agencies that rely on the Central Valley Project
will get just 5% of their contract supply, a dismally low
number. Although the figure could grow if California gets more
rain and snow, the allocation comes amid fresh weather
forecasts suggesting the dry winter is continuing. The National
Weather Service says the Sacramento Valley will be warm and
windy the next few days, with no rain in the forecast.

Twenty years ago, the Colorado River
Basin’s hydrology began tumbling into a historically bad stretch.
The weather turned persistently dry. Water levels in the system’s
anchor reservoirs of Lake Powell and Lake Mead plummeted. A river
system relied upon by nearly 40 million people, farms and
ecosystems across the West was in trouble. And there was no guide
on how to respond.
Radically transformed from its ancient origin as a vast tidal-influenced freshwater marsh, the Sacramento-San Joaquin Delta ecosystem is in constant flux, influenced by factors within the estuary itself and the massive watersheds that drain though it into the Pacific Ocean.
Lately, however, scientists say the rate of change has kicked into overdrive, fueled in part by climate change, and is limiting the ability of science and Delta water managers to keep up. The rapid pace of upheaval demands a new way of conducting science and managing water in the troubled estuary.
Colorado is home to the headwaters
of the Colorado River and the water policy decisions made in the
Centennial State reverberate throughout the river’s sprawling
basin that stretches south to Mexico. The stakes are huge in a
basin that serves 40 million people, and responding to the water
needs of the economy, productive agriculture, a robust
recreational industry and environmental protection takes
expertise, leadership and a steady hand.
Sprawled across a desert expanse
along the Utah-Arizona border, Lake Powell’s nearly 100-foot high
bathtub ring etched on its sandstone walls belie the challenges
of a major Colorado River reservoir at less than half-full. How
those challenges play out as demand grows for the river’s water
amid a changing climate is fueling simmering questions about
Powell’s future.
Voluntary agreements in California
have been touted as an innovative and flexible way to improve
environmental conditions in the Sacramento-San Joaquin Delta
and the rivers that feed it. The goal is to provide river flows
and habitat for fish while still allowing enough water to be
diverted for farms and cities in a way that satisfies state
regulators.
This event explored the lower Colorado River where virtually every drop of the river is allocated, yet demand is growing from myriad sources — increasing population, declining habitat, drought and climate change.
The 1,450-mile river is a lifeline to 40 million people in the Southwest across seven states and Mexico. How the Lower Basin states – Arizona, California and Nevada – use and manage this water to meet agricultural, urban, environmental and industrial needs was the focus of this tour.
The Colorado River is arguably one
of the hardest working rivers on the planet, supplying water to
40 million people and a large agricultural economy in the West.
But it’s under duress from two decades of drought and decisions
made about its management will have exceptional ramifications for
the future, especially as impacts from climate change are felt.
Every other year we hold an
invitation-only Colorado River Symposium attended by various
stakeholders from across the seven Western states and Mexico that
rely on the iconic river. We host this three-day event in Santa
Fe, N.M., where the 1922 Colorado River Compact was signed, as
part of our mission to catalyze critical conversations to build
bridges and inform collaborative decision-making.
Members of the 2019 Water Leaders class examined the
emerging issue of wildfire impacts on California’s water
supply and quality. Read their policy recommendations in the
class report, Fire and Water: An Emerging Nexus in
California, to learn more.
Many of California’s watersheds are
notoriously flashy – swerving from below-average flows to jarring
flood conditions in quick order. The state needs all the water it
can get from storms, but current flood management guidelines are
strict and unyielding, requiring reservoirs to dump water each
winter to make space for flood flows that may not come.
However, new tools and operating methods are emerging that could
lead the way to a redefined system that improves both water
supply and flood protection capabilities.
It’s been a year since two devastating wildfires on opposite ends
of California underscored the harsh new realities facing water
districts and cities serving communities in or adjacent to the
state’s fire-prone wildlands. Fire doesn’t just level homes, it
can contaminate water, scorch watersheds, damage delivery systems
and upend an agency’s finances.
California is chock full of rivers and creeks, yet the state’s network of stream gauges has significant gaps that limit real-time tracking of how much water is flowing downstream, information that is vital for flood protection, forecasting water supplies and knowing what the future might bring.
That network of stream gauges got a big boost Sept. 30 with the signing of SB 19. Authored by Sen. Bill Dodd (D-Napa), the law requires the state to develop a stream gauge deployment plan, focusing on reactivating existing gauges that have been offline for lack of funding and other reasons. Nearly half of California’s stream gauges are dormant.
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
recharged.
The southern part of California’s Central Coast from San Luis Obispo County to Ventura County, home to about 1.5 million people, is blessed with a pleasing Mediterranean climate and a picturesque terrain. Yet while its unique geography abounds in beauty, the area perpetually struggles with drought.
Indeed, while the rest of California breathed a sigh of relief with the return of wet weather after the severe drought of 2012–2016, places such as Santa Barbara still grappled with dry conditions.
The majestic beauty of the Sierra
Nevada forest is awe-inspiring, but beneath the dazzling blue
sky, there is a problem: A century of fire suppression and
logging practices have left trees too close together. Millions of
trees have died, stricken by drought and beetle infestation.
Combined with a forest floor cluttered with dry brush and debris,
it’s a wildfire waiting to happen.
Fires devastate the Sierra watersheds upon which millions of
Californians depend — scorching the ground, unleashing a
battering ram of debris and turning hillsides into gelatinous,
stream-choking mudflows.
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.”
Registration opens today for the
Water Education Foundation’s 36th annual Water
Summit, set for Oct. 30 in Sacramento. This year’s
theme, Water Year 2020: A Year of Reckoning,
reflects fast-approaching deadlines for the State Groundwater
Management Act as well as the pressing need for new approaches to
water management as California and the West weather intensified
flooding, fire and drought. To register for this can’t-miss
event, visit our Water Summit
event page.
Registration includes a full day of discussions by leading
stakeholders and policymakers on key issues, as well as coffee,
materials, gourmet lunch and an outdoor reception by the
Sacramento River that will offer the opportunity to network with
speakers and other attendees. The summit also features a silent
auction to benefit our Water Leaders program featuring
items up for bid such as kayaking trips, hotel stays and lunches
with key people in the water world.
Summer is a good time to take a
break, relax and enjoy some of the great beaches, waterways and
watersheds around California and the West. We hope you’re getting
a chance to do plenty of that this July.
But in the weekly sprint through work, it’s easy to miss
some interesting nuggets you might want to read. So while we’re
taking a publishing break to work on other water articles planned
for later this year, we want to help you catch up on
Western Water stories from the first half of this year
that you might have missed.
Our 36th annual
Water Summit,
happening Oct. 30 in Sacramento, will feature the theme “Water
Year 2020: A Year of Reckoning,” reflecting upcoming regulatory
deadlines and efforts to improve water management and policy in
the face of natural disasters.
The Summit will feature top policymakers and leading stakeholders
providing the latest information and a variety of viewpoints on
issues affecting water across California and the West.
New to this year’s slate of water
tours, our Edge of
Drought Tour Aug. 27-29 will venture into the Santa
Barbara area to learn about the challenges of limited local
surface and groundwater supplies and the solutions being
implemented to address them.
Despite Santa Barbara County’s decision to lift a drought
emergency declaration after this winter’s storms replenished
local reservoirs, the region’s hydrologic recovery often has
lagged behind much of the rest of the state.
Californians have been doing an
exceptional job
reducing their indoor water use, helping the state survive
the most recent drought when water districts were required to
meet conservation targets. With more droughts inevitable,
Californians are likely to face even greater calls to save water
in the future.
We have an unknown distance yet to run, an unknown river to explore. What falls there are, we know not; what rocks beset the channel, we know not; what walls ride over the river, we know not. Ah, well! We may conjecture many things.
~John Wesley Powell
Powell scrawled those words in his journal as he and his expedition paddled their way into the deep walls of the Grand Canyon on a stretch of the Colorado River in August 1869. Three months earlier, the 10-man group had set out on their exploration of the iconic Southwest river by hauling their wooden boats into a major tributary of the Colorado, the Green River in Wyoming, for their trip into the “great unknown,” as Powell described it.
Sixty percent of California’s
developed water supply originates high in the Sierra Nevada,
making the state’s water supply largely dependent on the health
of Sierra forests. But those forests are suffering from ecosystem
degradation, drought, wildfires and widespread tree mortality.
On our Headwaters Tour
June 27-28, we will visit Eldorado and Tahoe national forests to
learn about new forest management practices, including efforts to
both prevent wildfires and recover from them.
Even as stakeholders in the Colorado River Basin celebrate the recent completion of an unprecedented drought plan intended to stave off a crashing Lake Mead, there is little time to rest. An even larger hurdle lies ahead as they prepare to hammer out the next set of rules that could vastly reshape the river’s future.
Set to expire in 2026, the current guidelines for water deliveries and shortage sharing, launched in 2007 amid a multiyear drought, were designed to prevent disputes that could provoke conflict.
One of California Gov. Gavin
Newsom’s first actions after taking office was to appoint Wade
Crowfoot as Natural Resources Agency secretary. Then, within
weeks, the governor laid out an ambitious water agenda that
Crowfoot, 45, is now charged with executing.
That agenda includes the governor’s desire for a “fresh approach”
on water, scaling back the conveyance plan in the Sacramento-San
Joaquin Delta and calling for more water recycling, expanded
floodplains in the Central Valley and more groundwater recharge.
Bruce Babbitt, the former Arizona
governor and secretary of the Interior, has been a thoughtful,
provocative and sometimes forceful voice in some of the most
high-profile water conflicts over the last 40 years, including
groundwater management in Arizona and the reduction of
California’s take of the Colorado River. In 2016, former
California Gov. Jerry Brown named Babbitt as a special adviser to
work on matters relating to the Sacramento-San Joaquin Delta and
the Delta tunnels plan.
Groundwater helped make Kern County
the king of California agricultural production, with a $7 billion
annual array of crops that help feed the nation. That success has
come at a price, however. Decades of unchecked groundwater
pumping in the county and elsewhere across the state have left
some aquifers severely depleted. Now, the county’s water managers
have less than a year left to devise a plan that manages and
protects groundwater for the long term, yet ensures that Kern
County’s economy can continue to thrive, even with less water.
For the bulk of her career, Jayne
Harkins has devoted her energy to issues associated with the
management of the Colorado River, both with the U.S. Bureau of
Reclamation and with the Colorado River Commission of Nevada.
Now her career is taking a different direction. Harkins, 58, was
appointed by President Trump last August to take the helm of the
United States section of the U.S.-Mexico agency that oversees
myriad water matters between the two countries as they seek to
sustainably manage the supply and water quality of the Colorado
River, including its once-thriving Delta in Mexico, and other
rivers the two countries share. She is the first woman to be
named the U.S. Commissioner of the International Boundary and
Water Commission for either the United States or Mexico in the
commission’s 129-year history.
This tour explored the lower Colorado River where virtually every drop of the river is allocated, yet demand is growing from myriad sources — increasing population, declining habitat, drought and climate change.
The 1,450-mile river is a lifeline to 40 million people in the Southwest across seven states and Mexico. How the Lower Basin states – Arizona, California and Nevada – use and manage this water to meet agricultural, urban, environmental and industrial needs is the focus of this tour.

Although Santa Monica may be the most aggressive Southern California water provider to wean itself from imported supplies, it is hardly the only one looking to remake its water portfolio.
In Los Angeles, a city of about 4 million people, efforts are underway to dramatically slash purchases of imported water while boosting the amount from recycling, stormwater capture, groundwater cleanup and conservation. Mayor Eric Garcetti in 2014 announced a plan to reduce the city’s purchase of imported water from Metropolitan Water District by one-half by 2025 and to provide one-half of the city’s supply from local sources by 2035. (The city considers its Eastern Sierra supplies as imported water.)
Imported water from the Sierra
Nevada and the Colorado River built Southern California. Yet as
drought, climate change and environmental concerns render those
supplies increasingly at risk, the Southland’s cities have ramped
up their efforts to rely more on local sources and less on
imported water.
Far and away the most ambitious goal has been set by the city of
Santa Monica, which in 2014 embarked on a course to be virtually
water independent through local sources by 2023. In the 1990s,
Santa Monica was completely dependent on imported water. Now, it
derives more than 70 percent of its water locally.
The whims of political fate decided
in 2018 that state bond money would not be forthcoming to help
repair the subsidence-damaged parts of Friant-Kern Canal, the
152-mile conduit that conveys water from the San Joaquin River to
farms that fuel a multibillion-dollar agricultural economy along
the east side of the fertile San Joaquin Valley.
The growing leadership of women in water. The Colorado River’s persistent drought and efforts to sign off on a plan to avert worse shortfalls of water from the river. And in California’s Central Valley, promising solutions to vexing water resource challenges.
These were among the topics that Western Water news explored in 2018.
We’re already planning a full slate of stories for 2019. You can sign up here to be alerted when new stories are published. In the meantime, take a look at what we dove into in 2018:
As stakeholders labor to nail down
effective and durable drought contingency plans for the Colorado
River Basin, they face a stark reality: Scientific research is
increasingly pointing to even drier, more challenging times
ahead.
The latest sobering assessment landed the day after Thanksgiving,
when U.S. Global Change Research Program’s Fourth National Climate
Assessment concluded that Earth’s climate is changing rapidly
compared to the pace of natural variations that have occurred
throughout its history, with greenhouse gas emissions largely the
cause.
This 2-day, 1-night tour offered participants the opportunity to
learn about water issues affecting California’s scenic Central
Coast and efforts to solve some of the challenges of a region
struggling to be sustainable with limited local supplies that
have potential applications statewide.
The 1992 election to the United
States Senate was famously coined the “Year of the Woman” for the
record number of women elected to the upper chamber.
In the water world, 2018 has been a similar banner year, with
noteworthy appointments of women to top leadership posts in
California — Karla Nemeth at the California Department of Water
Resources and Gloria Gray at the Metropolitan Water District of
Southern California.
The 2018 Water Leaders class examined ways to improve water
management through data. Read their recommendations in the class
report, Catch the Data Wave: Improving Water Management
through Data.
In the universe of California water, Tim Quinn is a professor emeritus. Quinn has seen — and been a key player in — a lot of major California water issues since he began his water career 40 years ago as a young economist with the Rand Corporation, then later as deputy general manager with the Metropolitan Water District of Southern California, and finally as executive director of the Association of California Water Agencies. In December, the 66-year-old will retire from ACWA.
As the Colorado River Basin becomes
drier and shortage conditions loom, one great variable remains:
How much of the river’s water belongs to Native American tribes?
Native Americans already use water from the Colorado River and
its tributaries for a variety of purposes, including leasing it
to non-Indian users. But some tribes aren’t using their full
federal Indian reserved water right and others have water rights
claims that have yet to be resolved. Combined, tribes have rights
to more water than some states in the Colorado River Basin.
Just because El Niño may be lurking
off in the tropical Pacific, does that really offer much of a
clue about what kind of rainy season California can expect in
Water Year 2019?
Will a river of storms pound the state, swelling streams and
packing the mountains with deep layers of heavy snow much like
the exceptionally wet 2017 Water Year (Oct. 1, 2016 to Sept. 30,
2017)? Or will this winter sputter along like last winter,
leaving California with a second dry year and the possibility of
another potential drought? What can reliably be said about the
prospects for Water Year 2019?
At Water Year
2019: Feast or Famine?, a one-day event on Dec. 5 in Irvine,
water managers and anyone else interested in this topic will
learn about what is and isn’t known about forecasting
California’s winter precipitation weeks to months ahead, the
skill of present forecasts and ongoing research to develop
predictive ability.
In 1983, a landmark California Supreme Court ruling extended the public trust doctrine to tributary creeks that feed Mono Lake, which is a navigable water body even though the creeks themselves were not. The ruling marked a dramatic shift in water law and forced Los Angeles to cut back its take of water from those creeks in the Eastern Sierra to preserve the lake.
Now, a state appellate court has for the first time extended that same public trust doctrine to groundwater that feeds a navigable river, in this case the Scott River flowing through a picturesque valley of farms and alfalfa in Siskiyou County in the northern reaches of California.
This tour explored the Sacramento River and its tributaries
through a scenic landscape as participants learned 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 got an on-site update of Oroville Dam spillway
repairs.
“Dry, hot and on fire” is how the
California Department of Water Resources described Water Year
2018 in a recent report.
Water Year 2018 – from Oct. 1, 2017 to Sept. 30, 2018 -
marked a return to dry conditions statewide following an
exceptionally wet 2017, according to DWR’s Water
Year 2018 report. But 2017 was exceptional as all but two of
the water years in the past decade experienced drought.
Was Water Year 2018 simply a single dry year or does it
signal the beginning of another drought? And what can
reliably be said about the prospects for Water Year 2019? Does El
Niño really mean anything for California or is it all washed up
as a predictor?

There’s going to be a new governor
in California next year – and a host of challenges both old and
new involving the state’s most vital natural resource, water.
So what should be the next governor’s water priorities?
That was one of the questions put to more than 150 participants
during a wrap-up session at the end of the Water Education
Foundation’s Sept. 20 Water Summit in Sacramento.
People in California and the
Southwest are getting stingier with water, a story that’s told by
the acre-foot.
For years, water use has generally been described in terms of
acre-foot per a certain number of households, keying off the
image of an acre-foot as a football field a foot deep in water.
The long-time rule of thumb: One acre-foot of water would supply
the indoor and outdoor needs of two typical urban households for
a year.
