Ecosystems are dynamic and are impacted by disturbances such as a
drought, an extraordinarily freezing winter, and pests.
Longer-term disturbances include climate change effects.
Ecosystems provide a variety of goods and services upon which
people depend. Ecosystem management emphasizes managing natural
resources at the level of the ecosystem itself and not just
managing individual species.
The California Legislature was the first in the country to
protect rare plants and animals through passage of the California
Endangered Species Act in 1970. Congress followed suit in 1973 by
passing the federal Endangered Species Act.
A rookie California lawmaker plans to haul a 20-pound rodent
carcass into Congress on Tuesday to press his colleagues for
money to fight an invasive species wreaking havoc on his

Individual members of any species can vary dramatically,
something tied to genetic differences. That diversity comes in
handy when environmental conditions change. The drought, heat
and beetle outbreaks in recent years put extreme pressure on
sugar pines, creating a natural experiment that weeded out all

By any reckoning, the steelhead trout won a significant legal
victory this week, along with CalTrout and the Environmental
Defense Center, which have been arguing the case for two
decades. But it remains uncertain exactly how much more water
will have to be released downstream from Lake Cachuma to create
a habitat wet enough along the main stem of the Santa Ynez

While farm and private property interests cheered,
environmental groups last week bemoaned the Trump
administration finalizing the repeal of the controversial
“Waters of the United States,” or WOTUS, rule. We see little to
cheer or jeer at this point, as the repeal is hardly the final
chapter in a dispute that has stretched on for nearly 10 years.
An influx of Bay Area visitors to Sonoma County’s bucolic

Two bills to ban smoking at all state beaches — with a $25 fine
for violators — have reached Gov. Gavin Newsom’s desk and await
his signature. Former Gov. Jerry Brown vetoed similar bills
three times, saying people should be allowed to smoke outdoors
in parks. But this year there’s a new governor.
Before all those thousands of miles of levees went in, the
Central Valley had one of the West Coast’s largest salmon runs,
with a million or more of these mighty fish returning each
year. A big reason for the salmon’s suc-cess was that the
valley was among the most extensive floodplains in the world.
I’m writing to express our tribe’s dismay at Gov. Gavin
Newsom’s announcement that he plans to veto Senate Bill 1. …
Vetoing this bill will green-light President Trump’s plan to
divert even more water from our struggling rivers for
industrial agriculture. Many well-respected fish biologists and
environmentalists have concluded Trump’s attempt to ignore the
best science and rewrite the rules will essentially be an
“extinction plan” for Chinook salmon and other threatened fish.
Tijuana’s sewage system appears to be incapable of handling the
sewage generated in the Mexican city, and Imperial Beach Mayor
Serge Dedina called the situation unacceptable. Dedina hoped to
get the attention of President Donald Trump, who is in San

“There’s tremendous pollution being put into the ocean because
they’re going through what’s called the storm sewer that’s for
rainwater,” Trump said. “And we have tremendous things that we

are needles, there are other things.”
In 2019, at long last, justice was finally achieved; it was
secured through the combined power of the people and allies who
said it was finally time to bring safe water to all
Californians. On July 24, Gov. Gavin Newsom signed legislation
that will make sure all Californians have access to safe,
affordable drinking water.
A report that the homeless living along the San Gabriel

There is not enough water to support important wetlands and
springs in a semi-arid desert ecosystem that straddles the
Nevada-Utah border if all permitted and proposed groundwater
rights are put to use, according to a U.S. Geological Survey
study of the Snake Valley. There also may not be enough
groundwater to satisfy the desires of the Las Vegas area, whose
water agencies have eyed the valley for decades…
Newsom has said he won’t approve Senate President Pro Tem Toni
Atkins’ bid for a legal backstop against environmental
rollbacks by the Trump administration. And Washington is poised
to reduce protections for endangered fish species in the
state’s largest watersheds. The result may be the heightened
regulatory uncertainty that opponents of the bill said they
hoped to avoid…

Every degree of warming is expected to worsen what, in many
ways, is already a crisis for the state’s multibillion-dollar
agricultural industry. And a crisis here is a problem

critically endangered fish.
The Fox Canyon Groundwater Management Agency … discussed
reasons why the area will reduce pumping in the future to meet
its sustainability goals as it moves toward 2040. Cities can

Last week, the Legislature acted to thwart President Donald
Trump on water matters by passing a bill to essentially
pre-empt the execution of federal environmental law. The
Metropolitan Water District opposed Senate Bill 1 because it
would have unleashed rounds of state-federal litigation, and
would have likely brought 13 years of effort to a halt. Gov.
Gavin Newsom has signaled he plans to veto the measure.
State officials have ordered increased water flows on the Santa
Ynez River in Santa Barbara County to protect steelhead trout,
which are endangered in Southern California. The State Water
Resources Control Board action follows two decades of legal
efforts to address long-term declines in native fish
populations in the Santa Ynez.
Whatever satisfaction might be gained by telling the president
to pound sand is nowhere near as important as protecting the

movement of the fish when they get trapped below them.
Some 45,000 to 50,000 spring-summer Chinook spawned here in the
1950s. These days, the average is about 1,500 fish, and
declining. And not just here: Native fish are in free-fall
throughout the Columbia River basin, a situation so dire that
many groups are urging the removal of four large dams to keep
the fish from being lost.
There’s a lot to like about the Bay Area’s efforts to prepare
for sea level rise: the collaborative efforts, the detailed
studies and, laudably, the voters who are willing to tax
themselves with an eye to future needs. But if the long-term
threat is as grim as scientific projections indicate, local
experts say the region needs to respond with increased urgency
— an urgency that is at odds with the Bay Area’s often
cumbersome decision-making processes.
For San Franciscans … there are new worries for the city.
Fires now burn more regularly across the Sierra Nevada as well
as coastal mountain ranges. The flames may ruin plans for
weekend getaways to Yosemite or deliver noxious smoke to the
Bay Area. And locals may start to reach for air masks as
dangerously smoky days become more common.
Newsom saw SB 1 as a mortal threat to something he’s been
supporting since shortly before he took office: a tentative
truce in California’s longstanding water wars. The truce
revolves around the flow of water in and out of the Delta from
California’s most important river systems, the Sacramento and
The state’s moves open up more opportunities for extension of
drinking water service, operations and maintenance for domestic

Salmon and steelhead that were once abundant in this great
watershed are now at risk of extinction, a preventable disaster
that can be averted by moving forward with the planned removal
of four aging hydroelectric dams. While the Klamath River was
once the third-largest salmon producer on the west coast, its
fish runs have been declining for decades.
The city of South Gate plans to transform a weedy and rutted

Heather Hansman’s new book Downriver: Into the Future of Water
in the West explores the water emergency with remarkable calm
and even-handedness. She focuses on a single river, the Green
River, where ranchers, frackers, rafters, fishermen, and
urbanites all fight for their share of the water, while
contending with Byzantine state policies.
Removing the four aging hydroelectric dams from the river would
significantly improve ecological and geomorphic conditions
throughout the Klamath watershed and play a key role in
returning salmon to stable population levels.
Gov. Gavin Newsom plans to veto a bill passed by California
lawmakers that would have allowed the state to keep strict
Obama-era endangered species protections and water pumping
restrictions for the Sacramento-San Joaquin Delta. Newsom’s

passed the sweeping legislation.
Efforts to increase recycled water use in California got a
significant boost this week with the State Water Board’s
issuance of an order authorizing the Sacramento Regional County
Sanitation District’s program to deliver an average of 45
million gallons per day of recycled water from the Sacramento
Regional Wastewater Treatment Plant …
Completion and operation of the much-anticipated Pure Water
Monterey recycled water project have been delayed again and it
is now expected to miss another key water delivery deadline set
for the end of this year.
The three-year Colorado River System Conservation Pilot Program
(SCPP) started out modestly, with just 15 participating farms
and ranches the first year, but grew quickly as farmers
realized they could earn passive income for changing their
irrigation patterns, turning off the water they diverted from
the river earlier in the year when it carries more snowmelt,
and—in a few cases—fallowing some fields all together.
There’s no certain answer as to how the nutria population
re-emerged after being declared eradicated in California
decades ago but the population is spreading and causing serious
concern. The Department of Fish and Wildlife was recently
awarded $10 million to wipe out the large, invasive rodents and
that effort is now well underway.
Because there are moral, aesthetic, and legal obligations to
provide fish with water in streams, biologists like me often
get asked the question “Just how much water do the fish need,
anyway?” This, of course, is the wrong question…
Tiscornia Beach, an area on the lower American River frequented
by summer visitors, tested 7.5 times higher than the safety
threshold on Tuesday, according to data from the county and the
Central Valley Regional Water Quality Control Board. Samples of
river water taken two weeks earlier at nearby Discovery Park
tested almost 5.5 times higher than the safety threshold.
The project would build a new dam and expanded reservoir on the
North Fork of Pacheco Creek that could hold 140,000 acre-feet
of water, a substantial increase from the 5,500-acre-foot
capacity of the existing reservoir built 80 years ago.
The common reed, Phragmites australis, is one of the most
invasive plants in the world, and its numbers are widespread in
Suisun Marsh. … Phragmites can change ecosystem structure by
increasing tidal habitat elevations and reducing overall
habitat quality, including disturbing the food chain by driving
out native plants in the Delta that support wildlife such as
waterfowl and the endangered salt marsh harvest mouse.
Volunteers are needed for the 11th annual Great Sierra River

The flood insurance program has been plagued for years by
outdated maps of at-risk flood zones and billions of dollars in
accumulating debt, compounded by rising sea levels and
increasingly powerful storms strengthened by warming oceans.
… The result is that insurance premiums fail to reflect the
true risks to properties…
If we don’t manage groundwater pumping, levels of groundwater
as well as rivers and streams will decline, compromising the
wildlife, farms and cities that depend on them. By managing our
groundwater with the Sustainable Groundwater Management Act, we
are plugging leaks in the system.
The Trump administration, under Interior Secretary David
Bernhardt, is finalizing plans to rip up restrictions on
diverting Northern California water to its friends in the
agricultural industry in the dry western San Joaquin

districts oppose SB 1, hoping Trump administration efforts will
translate into increased water diversions.
In 2015, the Board of Supervisors gave initial approval to a
$58 million shoreline protection program to protect SFO from
sea-level rise. But on Wednesday, the board’s Budget and
Finance Committee approved an updated program that will now

new sea-level rise estimates and guidelines issued by the State
The Trump administration rolled back a key provision of the
Clean Water Act on Thursday, doing away with protections for
many wetlands and streams across the country… The repeal of
the Waters of the United States rule, however, will not

The new marine heatwave, which started spreading out from the
Gulf of Alaska in June and now covers much of the Pacific
Ocean, has not yet fully become The Blob 2, particularly in
California. Which means the effects, too, might not be as dire
as last time.
The Colorado River Basin’s 20 years of drought and the dramatic
decline in water levels at the river’s key reservoirs have
pressed water managers to adapt to challenging conditions. But
even more extreme — albeit rare — droughts or floods that could
overwhelm water managers may lie ahead in the Basin as the
effects of climate change take hold, say a group of scientists.
The western pond turtle in Butte County is currently shaking in
its shell, due to habitat alteration and introduced species
that are killing off the local reptile. … The turtle is being

Forecasts of strong winds in Southern California this week have
heightened concerns that the state’s fire season, tame in its
early stages compared to the devastation of last year,
could swing into destructive, even deadly mode.
We cannot advance the fight for environmental quality by
declaring that all science stopped on a specific date. If it’s

it in the Colorado below Morelos Dam, reminding us of the river
that once flowed there. It is agricultural drainage that comes
from farms in southwestern Arizona that use the Colorado River
to irrigate in the desert.
DWR is currently overseeing five habitat restoration projects
in Suisun Marsh. In October 2019, one of these projects, the
Tule Red Tidal Habitat Restoration Project – which converts
approximately 600 acres of existing managed wetland into tidal
habitat – is expected to finish construction.
Tucson’s below average rainfall for August, which is typically
the wettest month during monsoon season, might mean it’s time
to face the music and prepare for a potential short-term
drought, according to local weather experts.
A team of scientists has successfully teased out the influence
of human-caused climate change on wintertime precipitation over
the last century, showing that the warming climate altered
wintertime rainfall and snowfall across the Northern
According to a Customs and Border Protection spokesperson,
Organ Pipe Cactus National Monument has identified existing
groundwater wells construction contractors can use. In
addition, the contractor has proposed drilling new wells along
the border for the wall project. Currently, the construction
contractor estimates needing about 84,000 gallons of water per
day for the project.
There’s a lot of confusion and concern about what will happen
once the city of Ventura no longer discharges millions of
gallons of water into the Santa Clara River Estuary. … To
help residents get a better understanding of how Ventura’s
wastewater operations work, and to help answer those questions,
city officials opened up its facility to the public last week.
The rules specifically would restrict these non-federal
governments’ authority to review the water quality impacts of
projects that require a federal permit or license. These
projects range from pipelines to hydropower facilities to
dredging — any development that result in “discharge” into U.S.
In the Sacramento River near Redding this spring, water
districts, government agencies and others collaborated to
construct the Market Street Gravel Project to benefit fish. …
Reclamation District 108 Deputy Manager William Vanderwaal said
that to complete the $429,000 project, 12,000 tons of gravel
were placed into the river and developed as new spawning
habitat for chinook salmon and steelhead trout.
Much of the so-called microplastic was carried into the ocean
by storm runoff or in the flow from wastewater treatment
plants, and became embedded in sea floor sediment, said
Jennifer Brandon, a Scripps biologist who specializes in
As the old saying goes, if you can’t go through something, go
around it. And at an estimated cost of $357 million, the Friant
Water Authority is contemplating a 30-mile parallel canal to
circumvent the portion of the Friant Kern Canal that has been
negatively affected by subsidence.
It was only a little dam, a couple feet high, but it blocked
juvenile salmon from swimming the upper 2 miles of Ashland
Creek. On Tuesday, a powerful excavator tore it out with one
bite and soon the stream will be restored to its ancient look,
feel and flow.
Now, some are arguing that the bill should be stripped of its
longstanding provision applying the State’s own Endangered
Species Act to the operations of the federal Central Valley
Project. Here’s why that’s a terrible idea.
Passed by voters in November 2018, Measure W—the Safe, Clean
Water Program—imposed a 2.5 cent/sq. ft. parcel tax on
impermeable surface construction in LA County and is set to
provide upwards of $300 million annually to support stormwater
and clean water infrastructure projects. TPR spoke with Katy
Young Yaroslavsky, on the Board of Supervisors’ recent approval
of the Measure W Implementation Ordinance…
Nevada and Arizona, concerned that a 20-year drought has dried
up much of the river, are trying to rein in water use in an
effort to save the disappearing river. The river’s water levels
next year are projected to be just below the threshold of 1,090
feet laid out in the Drought Contingency Plan that was signed
earlier this year…
Crowfoot oversees a sprawling agency of 19,000 employees
engaged in the stewardship of the state’s forests and natural
lands, rivers and waterways, coast and ocean, fish and wildlife
and energy development. Now in its 36th year, the Water Summit
features a variety of policymakers, experts and stakeholders
discussing important topics in water across California and the
A few years ago, Paul Kehmeier did something unusual: He
decided not to water about 60% of his fields. He was one of a
few dozen farmers and landowners in Wyoming, Colorado, Utah,
and New Mexico who volunteered for a pilot program meant to
test out a new water-conservation strategy: Paying farmers to
temporarily leave their fields dry, to save the Colorado River.
A high-profile series of dog deaths has awakened the public to
the growing problem of toxic algal blooms, spurred by rising
temperatures and pollution. The blooms are emerging as a
national, not just regional, concern, according to preliminary
data reported to the U.S. Environmental Protection Agency
The county of San Diego says beachgoers should “feel more
confident” that water quality is being closely watched
throughout the region, especially along South Bay shorelines
where sewage pollution from Tijuana regularly fouls beaches.
The only bi-national financial institution dedicated to funding
environmental infrastructure projects along the border unveiled
six possible solutions to slowing down the cross-border sewage
spills that routinely shut down southern San Diego’s beaches.
The Bonneville Power Administration, the independent federal
agency that sells the electricity produced by the dams, is
careening toward a financial cliff. BPA is $15 billion in debt,
facing a rapidly changing energy market increasingly dominated
by wind and solar and a desperate need to maintain aging
infrastructure that’s expected to cost $300 million to maintain
and upgrade by 2023.
For perhaps the first time in 80 years the California State
Lands Commission … faced a decision this summer between
competing ideas for the same parcel. The commission staff
announced at the end of August that it will enter negotiations
to lease a shoreline parcel for a park in Burlingame,
potentially shaping the way the lands commission considers sea
level rise in its decision-making, and the way the Bay
shoreline is developed in the future.
Gov. Gavin Newsom recently signed an executive order to develop
a comprehensive strategy for making the state’s water system
climate-resilient. … In a related study
published earlier this year, Stanford researchers
Newsha Ajami and Patricia (Gonzales) Whitby examined
effective strategies to rising water scarcity concerns.
Our leaders in Washington filled me with so much hope earlier
this year when they approved permanent reauthorization of
the Land and Water Conservation Fund. , securing the near-term
future of one of our country’s oldest and most important
conservation tools. But we can’t truly call this a victory
until Congress takes that final step: permanent program
A new study by scientists at Lawrence Berkeley National
Laboratory uses a numerical model of an important watershed in
California to shed light on how wildfires can affect
large-scale hydrological processes, such as stream flow,
groundwater levels, and snowpack and snowmelt. The team found
that post-wildfire conditions resulted in greater winter
snowpack and subsequently greater summer runoff as well as
increased groundwater storage.
California’s 2018 Camp Fire was the deadliest blaze in state
history. … From all that destruction, a mysterious threat has
emerged for those who appeared to have gotten by unscathed:
household water supplies with concentrations of toxic
benzene—including one sample that had 923 times what the state
considers safe. More than nine months after the fire, the
Paradise Irrigation District still has a “do not drink” order
unless individual parcels have been cleared.
A new method to measure pore structure and water flow is
described in a study published in the journal Water Resources
Research. With it, scientists should be able to more accurately
determine how fast water, contaminants, nutrients and other
liquids move through the soil — and where they go.
While researching the impacts of industrial site restoration on
aquatic ecosystems in the Coyote Creek watershed, a major
tributary in the southern San Francisco Estuary, scientists
with the University of California, Davis, observed surprisingly
high densities of reproductive adult smelt in the marshlands,
which were not previously known to be heavily exploited by the
Water users in the Colorado River Basin have survived the
drought through a combination of water storage infrastructure
and voluntary actions to protect reservoir storage and water
supply. Adoption of drought contingency plans this summer,
developed over years of collaborative negotiation, takes the
next step by implementing mandatory action to reduce risk and
protect limited water supplies.
Those with wells within the Antelope Valley who pump more
groundwater than is allowed under a 2015 court settlement will
be required to pay between $415 per acre-foot and $948 per
acre-foot to replace the additional water, based on assessments
approved Wednesday by the Antelope Valley Watermaster Board.
A state court of appeal has upheld a Shasta County Superior
Court decision to stop a Fresno-based water district from doing
an analysis of the effects of raising the height of Shasta Dam.
The Westlands Water District had asked the California Third
District Court of Appeal to overturn the lower court’s
preliminary injunction that ordered the district to stop work
on an environmental impact report.
Last fall, the district began construction on a project to
remove sediment from the Littlerock Dam reservoir to increase
its storage capacity, but the winter rain flooded the
construction site and halted work for more than six months.
After decades of costly floods — and 65 years after Congress
first approved it — construction on Santa Clara Valley Water
District’s flood control project along the Upper Llagas Creek,
is finally happening.
There are a lot of reasons our watershed is unique. It’s a high
elevation terminal watershed, what could be more special? Well,
another contributing factor is that the terminus of the Truckee
River watershed exists on the largest Native American
Reservation in Nevada.
When California voters legalized cannabis in 2016, supporters
of Proposition 64 hoped it would significantly reduce the
scourge of black market weed cultivation, particularly on
public lands. Yet nearly two years later, illegal marijuana
grows are still rampant across wide swaths of the national
forests in California, leaving behind a trail of garbage, human
waste, dead animals and caustic chemicals.
A major oil spill in one of the nation’s most economically
important waterways could become more likely unless a plan to
dredge two San Francisco Bay channels less frequently is
reconsidered, lawyers for the state of California and a
conservation group argued in court Wednesday.
At the 2019 California Water Law Symposium, Professor Dave Owen
from UC Hastings gave the following overview presentation of
California water rights, including types of water rights,
governing agencies, and sources of regulatory authority, as

Finding a river in the West that still behaves like a Western
river — one that rises and falls with the annual rush of
melting snow — is tough. … But one major Western waterway
has achieved almost mythical status for its wildness: the Yampa
in northwestern Colorado.
The Paso Robles groundwater basin is one of three basins in the
state chosen to participate in a Stanford University study that
will deploy state-of-the-art aerial electromagnetic technology
to better understand its characteristics.
Known to locals as “Long Beach,” it’s part of the San Leandro
Shoreline Marshlands and once stretched at least 23 miles. The
most recent official estimate done back in 2008 put the beach
at seven miles amid development and rising sea levels.
The California State Board of Food and Agriculture will host a
public comment session on California’s Water Future on

50 million gallons of crude oil flowed out of the ground in an
uncontrolled release near a Chevron facility in Kern County
over the last 16 years.
ASU Now spoke to Sarah Porter, director of the Kyl Center for
Water Policy at ASU’s Morrison Institute for Public Policy,
about the cutbacks and what they will mean for Arizona’s
agriculture and the state’s roughly 7 million residents.
More and more land in California is going up in flames. The
area in the state burned by wildfires has increased by a factor
of five since 1972, according to a recent study, which
identified human-caused warming the likely culprit. So what’s
to be done? The Karuk Tribe wants to fight fire with fire.
The intent of the Salton Sea restoration is to mitigate losses
of habitat for wildlife as the Salton Sea shrinks. However,
mitigating lost habitat by replacing it with something harmful
does not result in any benefits to wildlife; in fact, it makes
things worse by creating a new exposure pathway that subjects
wildlife to contaminants.
Here we provide an updated account of Suisun Marsh fishes to
show why the marsh is so important for conserving fishes in the
upper San Francisco Estuary in general…and why we continue to
be enthusiastic about working there.
The Colorado is the most significant water supply source in the
West, but it carries an annual salt load of nine to 10 million
tons, said Don Barnett, executive director of the Colorado
River Basin Salinity Control Forum. … For the past 40 years,
the the forum has been “silently working away” at improving
water quality and lowering salt content on the Colorado, which
supplies water to 40 million people in seven states and Mexico.
The researchers — many of whom have been active in the
program’s rule making and have challenged the agency before —
argue in the working paper that the emissions reductions in
California’s offset program are inherently uncertain. In some
cases, they wrote, the rules create “perverse incentives”
toward increasing planet-warming gases.
While the guidelines are the strictest, most-health protective
levels proposed in the nation for these two PFAS chemicals, we
are deeply disappointed by the Water Board’s decision to focus
on just two of the many PFAS that have been detected in
California drinking water.
Shares of water resource specialist Cadiz (NASDAQ:CDZI) have
jumped 19.5% this month through Aug. 23, while the S&P 500,
including dividends, is down 4.3%. … The catalyst for Cadiz

entered the U.S. hemp market.
Preliminary analyses of water samples collected by researchers
at the Desert Research Institute in Reno revealed the presence
of particles of synthetic fiber and bits of red and blue
plastic no bigger than the head of a pin. “On one level, we’re
heartbroken and disappointed by this discovery,” said Monica
Arienzo, an assistant research professor at the institute and
leader of the investigation.
Environmental groups are raising concerns over a provision in
draft legislation they believe could exempt the Las Vegas
pipeline — a proposal to pump eastern Nevada groundwater about
300 miles to Southern Nevada — from further litigation and
federal environmental review.
Managing a river is no easy feat. Consider the needs for water
released at Shasta Dam into the Sacramento River: salmon need
cold water, sturgeon need warm water, and irrigators just need
water. Recent research shows that all three needs can be met in
all but the most drought-stricken years. How?
The latest assault on the Delta, which supplies roughly
one-third of the Bay Area’s water, is the Trump
administration’s efforts to gut the federal Endangered Species
Act. Removing protections in existence for nearly 50 years
threatens not only the Delta’s wildlife but also the quality of
its fresh water.
