Climate change involves natural and man-made changes to weather
patterns that occur over millions of years or over decades.
In the past 150 years, human industrial activity has accelerated
the rate of change in the climate due to the increase in
greenhouse gases (carbon dioxide, methane, and nitrous oxide).
Scientific studies describing this climate change continue to be
produced and its expected impacts continue to be assessed.
In California, the California Environmental Protection Agency has
found temperatures have risen by about 1.5 degrees since 1895.
Looking ahead, temperatures could rise by 2.7 degrees and its sea
levels by 55 inches in the next 40 years, according to the
California Energy Commission and the California Natural Resources
Agency. These are among the ongoing issues the state faces as it
grapples with climate change.
Already, California is confronting rising demand for water and
diminishing supplies. At the same time, the state’s water
infrastructure such as levees is increasingly aging and in
disrepair—conditions expected to be made worse by climate change.
Westlands Water District says a preliminary injunction ordering
it to stop work on an environmental impact report may prevent
it from helping to pay for raising the height of the dam,
according to the appeal filed last week.
Arguing that Monterey County officials improperly ignored new
groundwater impact information and a viable, even preferable
recycled water alternative, Marina Coast Water District has
sued the county and California American Water over the county’s
narrow approval of Cal Am’s desalination plant permit.
California’s rivers and streams have experienced enormous
changes over the past 150 years, and a warming climate brings
new challenges. We talked to Ted Grantham—a river scientist at
UC Berkeley and a member of the PPIC Water Policy Center
research network—about the state of the state’s rivers.
Abalone is a much-sought-after delicacy with a sweet, delicate
flavor similar to a sea scallop, say those who’ve tried it. …
But as marine heat waves, ocean acidification, habitat loss,
and overfishing shrink the red abalone fishery, the sweet
delicacy is at risk of permanently losing its food source: the
Although more fundamental ESA reform is needed, last week’s
action yielded modest and common-sense improvements to
implementation of an imperfect law. New efficiencies, clarity,

While wildfires have gotten much of the attention in California
as consequences of climate change, it’s really rising sea
levels that will likely wreak the most damage. With more than
25 million people living near the coast, some $150 billion
worth of property is at risk.
The Clovis City Council in July approved an amended deal with
the Fresno Irrigation District concerning the conveyance of
Kings River water to the city’s water system. … The agreement
includes “the addition of a new water supply to meet future
City growth and support implementation of the Sustainable
Groundwater Management Act (SGMA).”
The proposed rule would re-write EPA’s existing Section 401
implementing regulations and significantly narrow the authority
of states and Indian tribes when acting on Section 401
The desire to expand housing, commerce and other development
around metro Denver and on arid high plains once deemed
inhospitable has driven an innovative urban water broker to
build a $22 million reservoir on a ranch 70 miles east of the
city along the South Platte River.
Ariel Rubissow Okamoto, the editor in chief of Estuary Magazine
and long-time Bay Area science writer, talks about the
resiliency of the largest estuary on the West Coast, the
challenges facing the Sacramento–San Joaquin Delta, and the
potential impacts of climate change and sea-level rise on the
San Francisco Bay.
In a paper published Tuesday in the Journal of Applied Ecology,
scientists at the University of California, Santa Cruz and the
National Marine Fisheries Service used statistical modeling to
determine an optimal water management plan that would protect

Immigration law, tailpipe emissions and farm pesticides are on
the list that Sacramento takes up in defiance of the Trump
administration. Leaders elsewhere take note and join the cause.
Now comes the latest test: a chance for California to stop a
serious weakening of wildlife preservation laws embodied in the
45-year-old Endangered Species Act.
Integration is especially hard, and unavoidably imperfect, for
organizing common functions across different agencies with
different missions and governing authorities. … Much of what
is called for in California water requires greater devotion of
leadership, resources, and organization to multi-agency
Desalination began to lose its urgency among Californians and
their public officials two years ago, after the drought-busting
winter of 2016-17, when heavy rain and snow ended dry
conditions in most of the state. The idea of drawing potable
water from the sea became even less of a priority this year,
when an autumn of record-level fires gave way to one of the
state’s wettest winters on record.
A dozen conservationists gathered eagerly around the edges of

Los Angeles city and county representatives hosted a discussion
with state officials to address ways to increase local water
supplies and to support a proposed statewide water system. Los
Angeles Mayor Eric Garcetti was joined Friday by the California
Secretary of Natural Resources, Wade Crowfoot, and Secretary of
Environmental Protection, Jared Blumenfeld, to discuss the
city’s maintenance of its water sources.
Hydrogen sulfide is associated with the natural processes
occurring in the Salton Sea, a non-draining body of water with
no ability to cleanse itself. Trapped in its waters are salt
and selenium-laden agricultural runoff from surrounding farms,
as well as heavy metals and bacterial pollution that flow in
from Mexico’s New River, authorities said.
The Lake Powell Pipeline (LPP) proposal arose from a belief
that Utah has an unused share of the Colorado River and a fear
of water shortages stifling Washington County’s rapid
population growth. Although many leaders across the state say
southern Utah needs the LPP, this statement is not based on
Irvine Lake looks a lot different today than it did a year ago.
Last September the reservoir looked like a giant puddle at 13
percent of capacity, today, after a rainy winter, the water
covers the area and is ready to greet the public on Saturday,
Aug. 17. After a 3-year hiatus, Irvine Lake is reopening for
shoreline fishing on Aug. 17.
Not every bloom is toxic, but the toxins produced by the
blue-green algae can be harmful and even deadly for pets when
they eat the algae or drink the water, even in small amounts,
water experts warn. Summer heat, stagnant or slow-moving water
and nutrients from agricultural or septic runoff are an ideal
recipe for the toxic stew.
In a region that has already seen two 20-year droughts, the San
Bernardino Valley Municipal Water District continues to invest
in water supplies to help the region sustain prolonged
droughts. A new program offered by Valley District provides
financial incentive to local water agencies for projects that
produce recycled water or capture storm water.
The story behind a proposal to pump water from under the Mojave
Desert in San Bernardino County is a long and complicated one.
Since its approval in 2012, the Cadiz Valley Water
Conservation, Recovery and Storage Project has been tied up in
litigation from environmental groups, fought over in the state

Although prescribed burns have been part of federal fire policy
since 1995, last year the Forest Service performed them on just
one per cent—some sixty thousand acres—of its land in the
Sierra Nevada. “We need to be burning close to a million acres
each year, just in the Sierras, or it’s over,” said Jeff Brown,
manager of a field station in the Tahoe National Forest.
For most of the last 150 years, traditional Karuk burning
practices were criminalized. The Plan attempts to reverse all
this by re-establishing a more natural fire regime on the
landscape through prescribed burns at appropriate times of
With the last drought in the rearview and the next one

A team of researchers from Washington state recently studied
the effects of acidification on salmon’s sense of smell, also
known as “olfaction,” which is particularly important for
salmon to navigate back to their home streams to spawn. The
scientists made the alarming discovery that at the pH levels of
seawater predicted to occur in the next 50 to 100 years,
salmon’s sense of smell may be significantly impaired.
San Diego County’s eroding coastline is causing significant
public safety, financial and political challenges. … But
those shoreline changes seem certain to become more serious and
frequent because of sea-level rise, yet the public at large

existing and future development along the coast.
As the sun sets across Lake Tahoe, UC Davis researcher Brant
Allen and his team lower their sonar machine into the lake.
Thousands of little purple dots rise across the screen as they

Some areas of the country are predicted to see increased
flooding from hurricanes and other storms, while climate models
show the West, particularly California, will be getting dryer.
This will especially affect the water supply in California and
here locally in the Santa Clarita Valley, where we have long
depended on water from the melting Sierra snowpack to get us
through our hot, dry summers.
The U.S. Bureau of Reclamation on Thursday will release its
projections for next year’s supply from Lake Mead, a key
reservoir that feeds Colorado River water to Nevada, Arizona,
California and Mexico. After a wet winter, the agency is not
expected to require any states to take cuts to their share of
water. But that doesn’t mean conditions are improving long
California was the last Western state to pass legislation
regulating groundwater: the Sustainable Groundwater Management
Act of 2014 arrived after more than a century of development,
intensive agriculture, bouts of drought and the looming threat
that our aquifers will dry up. But the details of who would get
to pump what – and the financial cost of achieving groundwater
sustainability – are only now becoming clear.
Two species of Klamath Basin sucker have been dying before they
can reach adulthood, and U.S. Sen. Jeff Merkley is showing
continued interest in expediting efforts already underway to

Californians, your yard sprinklers are about to get a little
bit more expensive. The good news is, your water bill is about
to get cheaper. California on Wednesday officially adopted new
regulations which are estimated to save more than 400 million
gallons of water per day within 10 years, enough to supply San
Diego, the second largest city in the state.
Nowadays there’s about a 7 percent chance that snowy areas in
the western U.S. will get two really bad snow years in a
row—years with snowpack lower than a quarter of the long-term
average. But within a few decades, if climate change continues
apace, those bookending “snow droughts” could occur about 40
percent of the time, according to work published in August in
Geophysical Research Letters.
An unprecedented survey has revealed the loss of about 85

According to a 2017 report by the Outdoor Industry Association,
outdoor recreation generated $92 billion in consumer spending
in California and is directly responsible for 691,000 jobs in
the state. That’s why local residents and elected leaders have
sought additional safeguards to make sure that some of the more
extraordinary lands and rivers within the national forest and
monument receive permanent protection as wilderness and wild
and scenic rivers.
Butte County, California Water Service and Paradise Irrigation
District are kicking off the lengthy process on a project to

The Delta smelt is practically extinct in the wild already. So
could the Delta be repopulated by taking up the farmers’ offer
to “hatch and repopulate the fish,” as Jack Fowler says in

Except that the Delta smelt war has never really been about the
Delta smelt at all.
The proposed changes to Clean Water Act permitting rules,
announced Friday by the U.S. Environmental Protection Agency,
would limit the amount of time states and tribes can take to

Many farmers probably haven’t read the new report from the
United Nations warning of threats to the global food supply
from climate change and land misuse. But we don’t need to read
the science — we’re living it. Here in the San Joaquin Valley,
one of the world’s most productive agricultural regions,
there’s not much debate anymore that the climate is changing.
Other than talking of a “planned retreat” from the water and
bluffs, local government has a hard time getting its head
around this crisis. Like so many of our regional problems —
traffic, homelessness, housing — each government unit feels
somewhat powerless on its own. And with no accountability, the
real work is negligible. Meanwhile, California crumbles.
What would happen if we ran out of water? For an increasing
number of people, that question is moving from a hypothetical

In a newly published study, my colleagues and I analyze
year-to-year variations of future snowpack to see how
frequently western states can expect multiple years in a row of

long-standing water scarcity issues in the region. These
mounting pressures have a bevvy of potential implications, from
human health and ecological function, to food and energy
In recent years, algae blooms – actually microscopic bacteria
called cyanobacteria – have erupted in hundreds of lakes
nationwide, putting at risk Americans whose drinking water
comes from those lakes, or who swim, ski or fish in them. If
ingested, microcystins can cause adverse health effects in
people and animals, ranging from skin rashes to serious illness
and even death.
During the past 107 years, daily air temperatures measured in

The general rule of thumb had been that El Niño years — when
the sea surface in a region off the coast of Peru is at least 1
degree Celsius warmer than average — tend to have more
rainfall, and La Niña years, when that region is 1 degree
Celsius cooler than average, tend to have less rain. But that
simple rule of thumb doesn’t always hold true.
Whether you are a water utility manager, elected official, or
homeowner, future water availability is a concern. There are
several factors fostering that concern and one of them is
climate change. … But as the empirical evidence mounts and a

to review what a changing climate fundamentally means to
California’s water resources; arguably our most important.
While other regions grappled with destructive waves and rising
seas, the West Coast for decades was spared by a rare
confluence of favorable winds and cooler water. This “sea level
rise suppression,” as scientists call it, went largely
undetected. Blinded from the consequences of a warming planet,
Californians kept building right to the water’s edge. But lines
in the sand are meant to shift.

Hiding and waiting is a great strategy as long as droughts are
temporary. But as our climate becomes warmer, increased
evaporation will make it effectively ever drier, and rainfall
will arrive ever less predictably at the right time of year.
Native plants will thus face long-term increases in water
stress, often exacerbated by intensified fire and shifts in
their delicate coexistence with exotic species.
One year from its initiation of the design-build process for

A San Luis Obispo County policy regulating pumping from the
Paso Robles Groundwater Basin has hamstrung how Robert
Galbraith can farm his land. For decades, the family grew corn
silage, Sudan grass, alfalfa, and grains on their few hundred

though he can see many a green vineyard down the road.
Water is indeed the most precious natural resource in the arid
West and from that perspective it should come as no surprise
that water-rights issues on Lake Tahoe and Truckee River have
been at the center of negotiation and controversy since
pioneers first settled the region.
A bill signed Wednesday evening by Gov. Gavin Newsom will
require Cadiz Inc.’s Mojave Desert groundwater pumping
project to undergo further review to show it will not harm

Like many communities throughout California, Carpinteria faces
sustained and historic drought conditions. … In response to
the shortfall, CVWD proposes a $25 million project to take
wastewater that has been cleaned, purify it and then inject it
into the groundwater basin to be used for various needs,
including potable drinking water.
The Westlands Water District, which provides irrigation water
to farmers on the west side of the San Joaquin Valley, was
working on a report assessing the environmental impacts of
raising the height of the dam. But a judge ruled Wednesday that
Westlands’ work violated a state law that prohibited local and
state agencies from participating in any projects that would
have an adverse impact on the McCloud River.
California American Water is seeking to raise its Monterey area
average customers’ bills by nearly 18 percent over a three-year
period from 2021-2023. … Under the proposal, the “average”
Cal Am customer would see their monthly rates increase from
about $89.40 to $105.42 over the three-year period.
The San Diego County Water Authority’s Board of Directors last
week approved a contract to study the viability of a new
regional water conveyance system that would deliver water from
the Colorado River to San Diego County and provide multiple
benefits across the Southwest. The $1.9 million contract was
awarded to Black & Veatch Corporation for a two-phase study.
The findings of Tom Corringham and Daniel Cayan, both of the

Californians are worried about global warming causing severe
wildfires and consider the health of beaches and the ocean key
priorities, according to a new statewide survey focused on the
environment. … While the poll found significant concern about
rising seas and more extreme heat, it was at a lower level than
the preoccupation with wildfires.
California’s biggest river—the Sacramento—needs a lot of room
to spread in big water years. A floodplain project called the
Yolo Bypass allows it to flood naturally, while also providing
habitat for waterbirds, fish, and other aquatic species. We
talked to Ted Sommer, lead scientist for the Department of
Water Resources (DWR), about this versatile landscape.

assessments to customers — and specific projects to implement
The silvery panels looked like an interloper amid a patchwork
landscape of lush almond groves, barren brown dirt and saltbush
scrub, framed by the blue-green strip of the California
Aqueduct bringing water from the north. … Solar energy
projects could replace some of the jobs and tax revenues that
may be lost as constrained water supplies force California’s
agriculture industry to scale back.
While it may not be obvious to some, sustainable groundwater
management is inherently connected to the long-term survival of
the Delta. Not only does the state’s most significant
groundwater use occur in regions that also rely upon water from
the Delta watershed, reduced reliance on the Delta and improved
regional self-reliance are central to many of the goals
outlined in the Delta Stewardship Council’s Delta Plan.
It is seen as a major move from one of the world’s biggest
credit ratings agencies that could have a significant impact on
how seriously climate risk factors are viewed by financiers.
Based in California, Four Twenty Seven scores physical risks
associated with climate-related factors and other environmental
issues, including heat stress, water stress, extreme
precipitation, hurricanes and typhoons, and sea-level rise.
The heavy rains that hit the Central Coast this past winter are
keeping recreators at area lakes and reservoirs happy this
summer. However, the precipitation has done little to ease
concerns for a group fighting Monterey County over the water it
withdraws from Lake Nacimiento.
County and tribal officials are reporting that new testing at
sites around Clear Lake have revealed half a dozen areas with
cyanobacteria levels that trigger health warnings. Water
monitoring is regularly done by the Big Valley Band of Pomo
Indians and Elem Indian Colony, a valuable service that helps
facilitate safe lake use.
The water cycle is the movement of water on the planet — from
falling as precipitation, such as rain, ice or snow, to being
absorbed in the soil or flowing into groundwater and streams
and then being evaporated to start all over again. Research by
scientists from the U.S. Geological Survey shows water has been
moving more quickly and intensely through the various stages of
the cycle, according to NASA’s Earth Observatory.
John Reager is being honored for his work on the GRACE mission,
studying Earth’s water cycle by measuring groundwater, floods
and drought. This helps him and his colleagues study how
extremes of water vary with time and climate change.
Seven and a half years after it was formed, the Monterey
Peninsula Regional Water Authority is moving forward with a
smaller, less expensive version of itself. … The authority
has completed the vast majority of its mandate in backing a new
water supply for the Peninsula and can now be expected to shift
its focus toward dealing with the state water board’s Carmel
River pumping cutback order.
On Monday, the state of California and a coalition of fishing
groups and environmentalists asked a judge to bar Westlands
from completing a crucial environmental report in hopes of
stalling the project. “Everything we see looks to be illegal,”
said deputy attorney general Russell Hildreth. At issue is a
stretch of the McCloud River that both sides agree would be
inundated by the project.
California has grown from 10 million to at least 40 million
since 1950, making it necessary to move water over long
distances to where people live and work. Close to two thirds of
the state’s population is bunched in a few water-dependent
More than 61,000 acre-feet of snowmelt and rainfall has been
diverted from Mill Creek and the Santa Ana River by the
District and recharged into the groundwater basin for future
use by those who pump water from the basin. Imported water was
also used to help supplement the amount of water stored.
What happens when the farmer’s source of water is tapped out?
They look for it elsewhere. This could become a major problem
as their adaptation to climate change only exacerbates another
major impact from climate change—water scarcity.
Water is key to everything in California. If you have control
of water in sufficient amounts you control your destiny. There
are three things on the horizon that city leaders had best pay
heed before they buy into the PG&E model regarding critical
and essential utilities and go for the money in the here and

To reduce flooding on roads near Novato Creek, a Marin County
flood control agency and a local environmental group are
partnering to upgrade flood control equipment and improve
wetlands in the Simmons Slough basin.
The center, being built at North Natomas Regional Park, will
feature the city’s first 50-meter competition pool with 13
diving boards and lanes. It will also feature a 25-meter pool,

The report estimates there are a cluster of major California
crops that are particularly vulnerable to extreme temperature
changes: wine grapes, lettuce, almonds, strawberries, table
grapes, hay, oranges, cotton, tomatoes, walnuts, avocados, and
pistachios. Specifically, avocado production in California
could fall 40 percent by 2050 due to climate change factors.
Pacific salmon that spawn in Western streams and rivers have
been struggling for decades to survive water diversions, dams
and logging. Now, global warming is pushing four important
populations in California, Oregon and Idaho toward extinction,
federal scientists warn in a new study.
Moderator Kathleen Schock got an update on how the work is
progressing locally from Gary Serrato, executive director of
the North Kings Groundwater Sustainability Agency, Christina
Beckstead, executive director of Madera County Farm Bureau, and

Water is the lifeblood of the Sacramento Valley. Yet, the best
methods for storing and using the precious resource are often
elusive. A new water system in operation in Roseville treats
underground aquifers like a bank, making deposits in times of
surplus for withdrawal in times of drought.
Jennifer Gilden, the Pacific Fishery Management Council’s staff
officer for outreach, habitat and legislation, said the ocean
conditions are improving, though the Chinook salmon population
has yet to fully recover. Unfortunately, it is likely marine
heatwaves are only going to increase in frequency and intensity
in the coming years, according to a body of research on the
The newly formed water market would create a place where
farmers in the Rosedale district can buy and sell water based
on their needs. So if one farmer has too much for his crops in
a certain year, he’d be able to sell it on the market to
another who might not have enough.
The Sacramento-San Joaquin Delta is arguably the most
extensively studied and monitored ecosystem in the world. This
has generated mountains of data on everything from the
locations of the smallest fish to the water quality conditions
of the largest reservoir. Knowing where to access the most

district that serves a relatively modest population of 35,000,
just over 1% of the county.
More than 90% of U.S. wine comes from California, despite
growth in other states’ production, and it’s putting a strain
on the environment. Throughout the region, wine producers say
they’re striving to save water and use less pesticides, among
other measures aimed at sustainable growing, as they face the
challenges brought on by the advance of climate change.
New measurements taken in California’s Monterey Bay show that
it absorbs carbon dioxide emissions from the surrounding cities
and agricultural lands, making it more acidic. The finding is

By 2030, the Carpinteria Valley Water District estimates that
on a dry year, the deficit could be as high as 1,550 acre
feet—enough to fill 775 Olympic-sized swimming pools, or serve
the average yearly use of 6,200 local households. In response
to the shortfall, CVWD proposes a $25 million project to take
wastewater that has been cleaned, purify it and then inject it
into the groundwater basin…
When the population collapses, like it did between 2013 to
2016, the effects ripple across the ecosystem. Brown pelicans
struggled to reproduce and those that did abandoned their
chicks. Thousands of sea lion pups were found malnourished and
dehydrated on California’s beaches. These effects may be
exacerbated by humans, especially when high fishing rates
remain when stocks are in decline. California anchovies are
almost exclusively sold abroad as food for fish farms and bait
Thoughtfully implementing state law that requires local water
users to bring groundwater use to sustainable levels within the
next two decades will … result in withdrawal of large amounts
of land from agricultural production and the loss of economic
benefits. But we can repurpose those lands to support large
scale storage and solar, as well as other renewable energy
technologies that can help decarbonize our electric grid and
create new jobs in the Central Valley.
If you’ve read stories about the disaster afflicting Flint,
Michigan, you are probably grateful we still have good drinking

Gov. Gavin Newsom on Wednesday signed into law the Safe and
Affordable Drinking Water Fund bill in the tiny Fresno County
community of Tombstone Territory — where residents rely on
bottled water because their private wells are contaminated.
Starting next year, Senate Bill 200 will provide $130 million
annually to clean up drinking water in California communities
like Tombstone that lack access to safe water.
The Coleman National Fish Hatchery is expecting good returns of
their fish in the foreseeable future after a few lean years of
comebacks. … Mother Nature worked with the hatchery this year
providing high water levels and spring storms, said Galyean.
When nature was not working in the hatchery’s favor was during
the recent drought.
High-tech firms like Ceres, Prospera, Farmers Edge, and the
Climate Corporation are using artificial intelligence to help
famers decide when to plant, water, spray, and harvest their
crops. As climate change worsens rainstorms in the Midwest and
drought in California, the technology could also help growers
navigate more severe and volatile weather.
Katy Delaney pointed to an open patch of sediment at the base
of the canyon. A year ago, pools of cool water gleamed under
the sun and frogs basked on their banks. Now, a trickle of
water lazed through the mud. And the California red-legged
frog, whose fate had consumed eight years of Delaney’s life,
was nowhere to be seen.
During our Edge of Drought Tour Aug. 27-29, we’ll visit an
atmospheric river observatory in Santa Barbara that
specifically monitors the meteorological phenomenon and also
visit Lopez Lake to hear from the County of San Luis Obispo on
their cloud seeding efforts.
In areas where groundwater levels have fallen because of heavy
pumping, people have often responded by drilling deeper wells.
But exactly how much that has been occurring on a nationwide
scale wasn’t clear until water experts compiled nearly 12
million well-drilling records from state and local agencies
across the country.
During a recent trip to the Trinity River, I learned about the
many challenges facing its salmon and steelhead populations.
… But there is hope and evidence of progress in realizing

its 70,000-square-mile territory by the year’s end.
Close to $3 million worth of water has rushed down the Santa
Clara River over the past several weeks to recharge groundwater
basins in the Oxnard Plain. The release was part of a deal
between the United Water Conservation District and Fox Canyon
Groundwater Management Agency to help recharge aquifers still
struggling after years of drought.
After a few horrific years of extreme wildfires, California has
been taking steps to reduce future risks with new programs,
increased funding, and new policy efforts. We talked to Van
Butsic—a land use scientist at UC Berkeley and an adjunct
fellow at the PPIC Water Policy Center—about these efforts.
Gathering California water policy and decision-makers along
with groundwater stakeholders and users, the workshop gave
participants the opportunity to meet European Union (EU) water
specialists, exchange experiences and ideas, and compare
California and EU issues and solutions.
California regulators are teaming up with the United Nations to
develop “sustainable insurance” guidelines that would help
address climate-change-related disasters such as coastal
flooding and larger wildfires — the first such partnership of
its kind between the international organization and a U.S.
state, officials announced Tuesday.
For many years, federal “biological opinions” for delta smelt
and winter run chinook salmon have dictated restrictions on
operations of the pumps, reservoirs and canals of the federal

decade of science and on-the-ground experience with what we
know has not worked, long-awaited new federal biological
opinions are finally nearing completion.
Water managers on the Colorado River are facing a unique
moment. With a temporary fix to the river’s scarcity problem
recently completed, talk has begun to turn toward future
agreements to manage the water source for 40 million people in
the southwestern U.S. … Some within the basin see a window of
opportunity to argue for big, bold actions to find balance in
The state drought plans move gingerly toward encouraging
transfers of water by using clever euphemisms that avoid any
mention of water marketing. … These euphemisms are tools that
usher in a new frontier in western water law that will increase
resilience in the face of droughts, floods and forest fires
fueled by climate change.
The Trump Administration last year proposed to combine the
responsibilities of both the NMFS and the USFWS under one
federal roof. This would promote more efficient, effective, and
coordinated management of all ESA responsibilities for
anadromous and freshwater fish in Western watersheds, from the
highest reaches of our headwaters to the Pacific Ocean.
The Friant Water Authority is confident a parallel canal is the
best solution. This new one will be built in a way that
prepares for subsidence. A new canal would also benefit from
the Ground Water Management Act of 2014, which will regulate
how much and when water is pumped out of the ground, preventing
what some believe is the main cause of subsidence.
A new study looked at more than half a century of well depth
trends to gain new insights into the management of the critical
resource. … The team found that, between 1950 and 2015,
across most of the country, groundwater users are drilling
wells deeper and deeper. But well depths did not increase
everywhere … which means that, in some places, wells might
The Indian Wells Valley Groundwater Authority board of
directors took the first step Thursday to require all
