An ecosystem includes all of the living organisms (plants,
animals and microbes) in a given area, interacting with each
other, and also with their non-living environments (air, water
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.
To begin, what is arsenic? It is one of the basic chemical
elements found in the periodic table that shows its
relationship to other elements. Arsenic is dissolved from rocks
by water in areas that have groundwater pools. If you have
significant levels of arsenic in your water, it can cause
cancer, heart disease, diarrhea and affect your skin.
With support from EDF, four UC Santa Barbara graduate students

Decades of environmental protection is threatened to be undone
by the recent Trump Administration Executive Order to roll back
regulations from the Clean Water Act to speed up energy
projects. The proceeding EPA rule-making procedures make it
easier for owners of hydroelectric dam projects to bypass state

U.S. District Court Judge Dale Drozd of the Eastern District of
California, who is based in Fresno, denied environmental
groups’ request for an injunction that would have required the
U.S. Bureau of Reclamation, which operates the CVP, to reduce
water allocations as needed to manage water temperatures in the

For more than a decade, California’s governors have pushed for
“voluntary agreements” to establish rules for water diversions
by major urban and agricultural water districts, and to redress
their environmental impacts. Voluntary agreements crumbled
recently, after the state’s largest water districts walked away
from the table.
On June 18, 2020, the Third District Court of Appeal affirmed
the State Water Resources Control Board’s (“State Water Board”
or “Board”) authority to regulate what it deems to be an
unreasonable use of water, in this case through adoption of
emergency regulations establishing minimum instream flow
requirements to protect migration of threatened fish species
during drought conditions.
Adapting to climate change, coupled with the need to address
aging infrastructure, population growth, and degraded
ecosystems, requires significant investment in natural and
built water systems. These investments present a significant
opportunity to support not only water, but to provide economic,
social, and environmental benefits.

Degraded meadows and their streams can be rehabilitated using a
“pond and plug” technique to restore the floodplain function.
This strategy aims to elevate groundwater levels in the dry

While there are numerous factors that can lead to increased
wildfire risk, a growing body of scientific evidence finds that
climate change is a wildfire “threat multiplier,” amplifying
both natural and human risk factors. But how climate will
influence western communities and ecosystems varies
considerably. Two recent studies in California and the Pacific
Northwest help to bring some of this into better focus.

Water and the question of what constitutes its sustainable use
is becoming an increasingly important subject everywhere with
each passing year, but in few places is it more crucial than in
the Carrizo Planning Area of California Valley
After an absence of many decades, Chinook salmon swim up the
Guadalupe River in San José most winters. The fish look for
places to lay eggs and often find them. If there’s enough water
left in the dry season, their offspring swim back down the
river in the spring to head out to sea. Surprisingly, given the
generally heated politics regarding fish in California, little
else is known about these salmon.
As the Salton Sea retreats, leaving the dry playa exposed, dust
particles become airborne and mobilize lung-damaging toxins
from agricultural runoff. Red Hill Bay, located near the
southeastern corner of the sea, would restore habitat by

American Indian tribes in California’s Klamath Basin praised
Monday’s decision by the United States Supreme Court not to
hear the Klamath Project irrigators’ Fifth Amendment water
rights case, Baley v. United States. By not hearing the case,
the Supreme Court upheld the Klamath Tribes’ treaty water
rights as the most senior water rights in the Klamath Basin.
These water rights are critical to protect the tribes’
fisheries and traditional way of life.
The creation of the Council was, in many ways, an experiment in
governance by the California State Legislature and

With a global pandemic, a catastrophic economic recession and
record-high unemployment, one would think the state has enough
issues to tackle. But proponents of a state water grab that I
have been fighting since the day I was sworn into office in
2012 disagree. Where others see turmoil and anguish, they see
opportunity. Apparently, they believe in the adage, “Never let
a crisis go to waste.”
The suit, filed by Earthjustice on behalf of Sierra Club, other
environmental groups, and a number of tribes, argued the Trump
administration erred in removing protections for wetlands and
streams that result from rainfall.
On June 22, 1980, Lake Powell reached its capacity for the
first time, marking a grim milestone for environmentalists who
have never forgotten the loss of Glen Canyon. Before the waters
began pouring in, it was a maze of towering sandstone cliffs
and spires, with thousands of indigenous ruins now mostly lost.
As crews continue to battle a human-caused wildfire that has
become one of the largest in Arizona history, state agencies
are concerned about the potential impact on wildlife and water
resources. The Bush Fire, now the fifth-largest fire on record,

Monday morning… The Tonto National Forest encompasses some of
the main water sources for Phoenix residents.
Each year millions of liters of fire-retardant chemicals are
applied to wildfires across the nation. The use of these
retardants could have significant effects on downstream
nutrients. The aim of this study will be to determine which

The recovery from the COVID shutdown gives us a rare
opportunity to rethink our relationship with the global
ecosystems on which we depend. Like so many others, I long for

A federal Judge in California on Friday rejected a request for
a nationwide injunction of the rule. Hours later, a federal
Judge in Colorado agreed to freeze the federal rule within that
state. The California court’s decision is a major blow to
environmentalists and states that had hoped to block the
Navigable Waters Protection Rule across the country before it
takes effect Monday.

Living in cold streams fed by underground springs, the Shasta
crayfish is California’s last native crayfish. Listed as
endangered in 1988, the once prolific crayfish have declined
over the past 20 years to the point where only about 500

If there’s one certainty in these uncertain times, it’s that
nature is resilient, and one needn’t look further than the San
Joaquin River as an example. For a second year in a row, and
for only the second year in over 65 years, spring-run Chinook
salmon have returned from the ocean to spawn in the river and
bring forth the next generation.
A smidge over 200 acres, the Wright Wetland Preserve is easily

The Fish Friendly Farming Certification Program was designed to
improve water quality and to restore and sustain habitat for
federally-listed threatened species like Chinook salmon and
steelhead trout. In a stunning victory for fish, farming and
our environment, Fish Friendly Farming has already certified 90
percent of all Napa grape vineyards.
Although the Clean Water Act will still protect heavily used
waterways in Nevada, including the Colorado River and the
Truckee River, it excludes many wetlands and most seasonal
streams. As a result, the rule has set off a flurry of legal
challenges from environmental groups. And in recent months,
several Democrat-led Western states, including Colorado,
California and New Mexico, have sued the Trump administration
to challenge the final rule. Nevada has not joined those suits.
The COVID-19 pandemic has changed the way families, educators
and students can experience state parks — through expanded
online programs. … Education coordinator Anne Marie Tipton
says the Tijuana River National Estuarine Reserve’s
virtual field trips teach classrooms around the state about the
estuary’s role in the environment.
In order for the Chinook and steelhead to rebound in the Eel
River, there should be at least 26,400 fish returning from the
ocean to spawn annually… Although the Eel salmon population
was larger this year than last, Fish and Wildlife’s June 1
report shows the population fell far below the margin for
species recovery. Only 8,263 made the journey, they wrote.
Oil, logging, mining, and grazing will be the priorities of
national forests and grasslands, with expedited environmental

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

community in the restored area.
Hundreds of studies on nature-based solutions to extreme events
show that “green infrastructure” is often cheaper and more
effective than engineered projects like dams, levees and sea
walls, according to a new analysis. Experts say federal and
state governments should heed those findings and increase
funding for natural landscapes and systems to reduce climate
disaster risk. Solutions include floodplain restoration and
“living shorelines” along vulnerable coasts and rivers.

the road. “All told, the board is looking at around a 30 to 35%
reduction in productivity,” said Patrick Pulupa, executive
officer for the regional board, during a meeting Thursday.
Farmers and ranchers in the Klamath Project are breathing a
sigh of relief after the U.S. Bureau of Reclamation announced
Tuesday it will not further reduce this year’s water allotment,
which is already less than half of demand. … On the other
hand, tribal members that depend on ample salmon runs for their
way of life argue the runs will continue to suffer in warm, low
rivers without enough flow for them to migrate and spawn.
Any potential alignment of the Lake Powell pipeline would pass
through lands that hold spiritual and cultural significance to
Southern Paiutes, who fear the project would jeopardize their
culture and upset the balance of nature.
To assess the range of pandemic-related issues confronting the
sector, the PPIC Water Policy Center held a series of
conversations with representatives from state and federal
agencies, water utilities, environmental nonprofits, and
businesses that specialize in restoration. The pandemic’s
impact falls into three categories: disruption of monitoring
and research programs, delays to restoration projects, and the
threat posed by the economic downturn to funding for this work.
Here are some key takeaways.
Imagine taking a kayak out on the water all day as a full-time
job. Well, that’s exactly what the U.S. Fish and Wildlife
Service employees from the Red Bluff office do for a portion of
the year. The work is critical for surveying Clear Creek for
the presence of steelhead, rainbow trout and late-fall Chinook
salmon nests known as redds.
Water pollution in San Francisco Bay, California has reduced
significantly due to the reduction in traffic, according to a
recent study in the journal Science of the Total Environment.
The toxic particles emitted by cars, in fact, fall into the
surrounding waters, inlets and on the coast for miles.
Over the years, much attention has been given to California’s
drought, but less is known about the more than one million
Californians in more than 300 communities who don’t have access
to clean drinking water. To address this crisis, CSU faculty
and students are performing community assessments, conducting
research and assisting local engineering projects, often with
support from Water Resources & Policy Initiatives. Take a look
at some of the CSU’s ongoing work.
The Solano County Water Agency has filed an appeal with the
Delta Stewardship Council regarding the consistency
determination submitted by Westlands Water District for the

that will be impacted…
In his time with the commission, which has the responsibility
for applying the boundary and water treaties between the United
States and Mexico, the two nations have taken huge steps
forward in assuring that commitments to the primary binational
water agreement in the Southwest – the 1944 Mexico-U.S. Water
Treaty – were faithfully upheld.
The group aims to counter the narrative that the outdoors
aren’t for Black people, educate people about challenges people

Birders Week shows that the Black experience is more than
trauma, that it is about pride, is about joy. It is about
resilience, strength and style,” says Tykee James, a Black
Birders Week organizer and the National Audubon Society’s
government affairs coordinator.
The first slide of Daybreak Power’s first-ever presentation to
potential investors quotes Paul Allen, the legendary co-founder
of Microsoft, asking what he calls the most exciting question
imaginable: “What should exist? … What do we need that we don’t

This spring marked the fifth anniversary of the California
EcoRestore initiative, a coordinated effort across state
agencies to deliver 30,000 acres of restored fish and wildlife
habitat in the Sacramento-San Joaquin Delta, an immensely
important landscape that five years ago only had 5 percent of
its native habitat remaining.
Three months after federal dam safety regulators ordered
Anderson Reservoir, the largest reservoir in Santa Clara
County, to be drained due to earthquake concerns, new details
are emerging on what will happen to all that water, the fish
that depend on it, and the water supply for Silicon Valley.
In 1984, a small group of California surfers were fed up with
the development and water pollution at their favorite break,
Malibu’s Surfrider Beach. They took their environmental
concerns to California State Parks officials — and prevailed.
The Surfrider Foundation was born.
On May 21, the Southern Nevada Water Authority board of
directors voted to indefinitely defer its groundwater
development project, which opponents had dubbed the “water
grab.” The unanimous vote brought an end to more than three
decades of acrimonious battle with the Great Basin Water
Situated between Bethel Island and False River and accessible
only by boat, Franks Tract is primarily used by fishermen,
boaters and waterfowl hunters. But, over the past several
years, the Department of Fish and Wildlife has been studying
ways to restore part of the 3,523-acre underwater state park to
its original marshland in the hopes of reducing saltwater
intrusion into the Delta and more.
EPA’s final rule that curtails states’ authority over Clean
Water Act permitting of pipelines, hydroelectric dams and other
energy projects could run afoul of a 1994 Supreme Court ruling
that originally granted states that oversight power.
California and federal water regulators are trying to quickly
resolve their legal dispute over competing biological opinions
governing the management of their respective water projects, a
top state official says. The talks are proceeding after Gov.
Gavin Newsom filed suit in February to nullify new federal
opinions that would ease restrictions on surface water for San
Joaquin Valley growers.
When most people think of sea otters, they picture these
charismatic creatures wrapped in kelp as they float on their
backs in the ocean. But this iconic image is only part of the
story. Sea otters also once abounded in the San Francisco Bay
and other coastal estuaries. Now, a team of sea otter experts
is raising the idea of bringing sea otters back to our bay.
As big corporations consume mass amounts of water, the smaller,
local communities near the plants, factories and corporate
offices have fewer resources. Water shortages then become
prevalent as the corporation continues to use up the nearby
sources. … In order to make a meaningful change for smaller
communities, big corporations will need to work on
The $65.8 million in grants will help fund projects such as
groundwater replenishment and habitat restoration within the
Colorado River, Lahontan, San Francisco Bay Area and Santa Ana
Proposition 1 funding areas. More than $12 million of this
amount targets projects that also help disadvantaged and
underrepresented communities, including Tribal governments.
A long-sought compromise has been approved that will open the
stagnant, reed-filled Buena Vista Lagoon to the sea and restore
its native coastal marine habitat, but years of work remain
before the transformation begins.
Researchers analysed the records of nearly 3 million births in
California to women living within 6.2 miles (10km) of at least
one oil or gas well between 2006 and 2015. … Active and
inactive oil and gas sites create myriad environmental hazards
including air and water pollutants, noise and excessive
lighting, which have all been linked with poor health outcomes.
The Department of Water Resources urged people to avoid
physical contact with the water at San Luis Reservoir in Merced
County until further notice due to blue-green algae. Boating is
allowed, but swimming and other water-contact recreation and
sporting activities are not considered safe under the warning
advisory due to potential adverse health effects.
The water rights behind the proposed Lake Powell pipeline are
not actually coming from the project’s namesake lake, but
rather from the major reservoir upstream on the Green River.
Now, Utah water officials’ new request to overhaul those rights
has handed opponents a fresh opportunity to thwart the proposed
pipeline just as federal officials are about to release a
long-awaited environmental review of the $1.2 billion
Georgia, West Virginia, and 21 other states moved to intervene
in litigation in order to help defeat challenges to the
Navigable Waters Protection Rule—a joint regulation from the
Environmental Protection Agency and Army Corps of Engineers
that narrows the types of wetlands and waterways subject to
federal Clean Water Act restrictions.
After only 6 months post-construction completion and levee
breach at the Tule Red Tidal Restoration Project, longfin smelt
have returned. The 420-acre restoration site converted wetlands
managed primarily for waterfowl to tidal wetlands for the
benefit of dwindling native fish populations including Delta
smelt, longfin smelt, Chinook salmon and the food web that
U.S. policymakers understand quite well the impact of Mexico’s
wastewater management on American communities. What they fail
to comprehend is that the ongoing border sewage crisis is
rooted in a longer history of U.S. imperialism and private
enterprise in the San Diego-Tijuana region.
The proposals from the Bureau of Land Management would
eliminate a 15-day protest period afforded to the public to
comment on timber sales and other forest management decisions.
BLM said the comment period they are proposing to cut is
repetitive, as people can already submit their thoughts when a
project is undergoing review under the National Environmental
In a stark reminder that drought has once again taken hold on
the North Coast, Sonoma County is preparing to ask state water
regulators for permission to reduce water levels in the Russian
River this summer to conserve water stored in Lake Mendocino
and ensure minimal late-season flows for fish.
The National Audubon Society has reached an agreement with the
Arizona Department of Water Resources to help fund the Colorado
River Indian Tribes’ on-going efforts to conserve 150,000
acre-feet of water in Lake Mead over the next three years.
By the thousands, they rolled through the Southern Oregon
countryside in tractors, hay trucks, log trucks, pickups and
minivans, their hand-painted signs greeted by supportive
passers-by who agreed with the message of Friday’s “Shut Down
and Fed Up” rally: the water problems that for decades have
plagued the region and its farmers must be resolved.
Restoration of the 500-plus acres of wetlands has been a goal
for literally decades of both city officials and environmental
advocates. Since the discovery of oil there in 1926, combined
with the channelization of the San Gabriel River, the once
2,400-acre wetlands complex has been landfilled, graded and
activated as a working oil field. Much of the remaining
wetlands is controlled by Beach Oil Minerals Partners (BOMP).
A recent study published in the journal Science helps explains
why, revealing that the south-western US is in the grip of a
20-year megadrought – a period of severe aridity that is
stoking fires, depleting reservoirs and putting a strain on
water supplies to the states of the region.
A major UK government-funded research study suggests particles
released from vehicle tyres could be a significant and
previously largely unrecorded source of microplastics in the
marine environment. The study is one of the first worldwide to

The report could revive past attempts to mine uranium in the
Los Padres National Forest in San Luis Obispo and Ventura
counties, including a tract of land near Lake Casitas in the
Ojai Valley, a source of drinking water for Carpinteria Valley
Water District. Many of the report’s recommendations will
require additional action before taking effect, such as changes
to agency rules or regulations, or passage of legislation.
At its May quarterly meeting, the Wildlife Conservation Board
approved approximately $36.2 million in grants to help restore
and protect fish and wildlife habitat throughout California.
Some of the 31 approved projects will benefit fish and wildlife
— including some endangered species — while others will provide
public access to important natural resources.
Anticipating where a fire is likely to ignite and how it might
spread requires information about how much burnable plant
material exists on the landscape and its dryness. Yet this
information is surprisingly difficult to gather at the scale
and speed necessary to aid wildfire management. Now, a team of
experts in hydrology, remote sensing and environmental
engineering have developed a deep-learning model that maps fuel
moisture levels in fine detail across 12 western states
Marine life mitigation, the need for desalinated water in
Orange County and the overall merits of Poseidon Water’s plan
to build a $1 billion desalination plant in Huntington Beach
were some of the main talking points of a 10-hour virtual

workshop: pointed questions about the merits of Poseidon’s
Two factors are believed to weigh heavily on the Delta smelt’s
fate. The biggest is the reduction in fresh water in the Delta
since water started flowing southward via the California
Aqueduct in the 1960s. … The other threat to Delta smelt are
larger fish particularly non-native striped bass and largemouth
bass that were introduced to the Delta by man.
The extraction methods that these operations use today are not
drastically different from processes that miners employed in
the California gold rush in the mid-1800s. Today we see history
repeating itself in places like the Peruvian Amazon, where
small-scale gold mining threatens to leave behind long-lasting
social, economic and environmental consequences.
In 2014, the Cleveland National Forest (CNF) initiated an
effort to restore the migratory corridors for fish and other
aquatic species in the San Juan and Santiago Watersheds by
removing the remnants of small (approximately 2 – 15 ft) dams
constructed by Orange County (California) between 1940-70s.
It was during the drought in the late-1980s that Robin Kulakow
and her fellow birdwatchers began noticing that Putah Creek was
running dry. The same observation was being made at places such
as Camp Davis, a popular site near the university where youth
paddled their canoes and participated in other activities.
Clear Lake is one of the richest lakes in the state when it
comes to nutrients. That is one reason we have algae blooms as
well as a massive amount of aquatic weeds. Some of the species
of aquatic weeds have been in the lake for more than a million
years and others only a few years. These new arrivals are
classed as foreign invasive weeds.
The $100m debt facility will cover the costs of finishing
projects including the Stockton data center which is expected
online in late 2020. The barge-borne data center will use the
company’s signature cooling system, cold water, and a system of
heat exchangers that use the water surrounding the building as
When a Phoenix company floated a proposal last year to build
two hydroelectric dams on the Little Colorado River, it faced
an outpouring of opposition. … Taking note of the criticisms,
the two businessmen who run the company have pivoted to a
different approach. They propose to move the project off
the Little Colorado River to an adjacent canyon to the east,
where they would build four dams.
Construction crews will soon begin work to restore Marsh Creek
along a nearly one-mile, treeless stretch near downtown
Brentwood. Crews are expected to close off the trail in the
area from Sungold Park to Dainty Avenue on Tuesday in the first
phase of a project to improve habitat and water quality for
fish and birds and to create a shady, natural creek corridor
for residents while keeping the community protected from floods
The Hi-Desert Water District opposes the proposed new status,
noting that the Joshua tree is already protected locally with
both city and county ordinances. They also said that, if the
listing was approved, it could deter people from building in
the Morongo Basin because most undeveloped plots in the area
have Joshua trees that developers will have to transplant or
Citing conservation gains and a third straw to the bottom of
Lake Mead, the Southern Nevada Water Authority on Thursday
voted to shelve a proposal for a multi-billion pipeline that
would have moved water from Northern and Eastern Nevada to Las
Vegas. The vote means the pipeline staunchly opposed by rural
communities, American Indian tribes and conservationists is
dead – or at least going into a long, deep coma.
Thursday, the Redwood Coast Land Conservancy announced that it
has received three grants totaling over $2.1 million for the
Gualala River Mill Bend Conservation Project that they are
stewarding for the community.
The Klamath Project, a U.S. government-operated waterworks that
steers runoff from the towering Cascades to more than 200,000
acres of potatoes, alfalfa, wheat, onions and other produce on
both sides of the state line, is running low on supplies. The
local water agencies served by the project say they may not
have water to send to farms beyond next month.
Outbreaks of E. coli illness that sickened 188 people who ate
romaine lettuce grown in California probably came from cattle
grazing near the farms, the U.S. Food and Drug Administration
said in a report released Thursday. … Investigators concluded
that the illness was centered on ranches and fields owned by
the same grower and that were located downslope from public
land where cattle grazed.
The Southern Nevada Water Authority voted Thursday to withdraw
all pending groundwater importation applications, return a
right-of-way associated with groundwater importation plans to
the Bureau of Land Management and take other actions to move
the multibillion-dollar groundwater development project —
sometimes referred to as the water pipeline project — into
“indefinite deferred status.”
ACWA retained Probolsky Research to conduct a bilingual
statewide survey of 900 California voters during March. The
results showed that a majority of respondents – 62% –
support Voluntary Agreements as an approach under development

conservation organizations, farmers and state and federal
In letters addressed to Interior Secretary David Bernhardt and
Gov. Gavin Newsom, the Association of California Water Agencies
is urging state and federal officials to rejoin talks on
voluntary agreements to address ecosystem needs in the
Sacramento-San Joaquin Delta.
The agreement between property owners, nonprofits and multiple
governmental agencies outlines a plan to remove the weir, or
low wooden dam at the mouth of the lagoon, and excavate the
entire 220-acre preserve to restore tidal flushing. … Without
intervention, the lagoon would continue to fill with sediment
and vegetation until it eventually disappears.
Increased frequency and severity of droughts threatens
California’s endangered salmon population — but pools that
serve as drought refuges could make the difference between life
and death for these vulnerable fish, according to a study by
researchers from UC Berkeley and California Sea Grant…
The authors provide an overview of how water supports Earth’s
resilience and propose an approach for analyzing and better
understanding global water cycle modifications focused on three
central questions: What water-related changes could lead to
global tipping points? How and where is the water cycle
particularly vulnerable? And how do local changes in water
stores and fluxes affect regional and global processes and vice
For Indians, confronting economic uncertainty and food
shortages has been part of life since Europeans arrived in our
lands. … This is why the Yurok Tribe is fighting so hard to
remove Klamath River dams and restore the salmon runs that have
fed our people since the beginning of time.
Foothill Yellow-legged Frogs have begun to spawn, laying small
snow-globe sized egg masses in streams and rivers. They are one
of the few stream-breeding frogs endemic to California and
Oregon. This species is a good indicator of stream health
because they link aquatic and terrestrial ecosystems and are
strongly tied to natural seasonal cues associated with local
The Trump administration’s long-anticipated water jurisdiction
rule has already drawn a half-dozen legal challenges since its
April release, with more on the way. The Navigable Waters
Protection Rule narrows which types of wetlands and waterways
trigger federal Clean Water Act oversight, replacing
interpretations by Obama-era officials and earlier
administrations. … Here’s a breakdown of key legal arguments:
A new study led by Adam Schreiner-McGraw, a postdoctoral
hydrology researcher at University of California, Riverside,
modeled shrub encroachment on a sloping landscape and reached a
startling conclusion: Shrub encroachment on slopes can increase
the amount of water that goes into groundwater storage. The
effect of shrubs is so powerful that it even counterbalances
the lower annual rainfall amounts expected during climate
Facing uncertain revenues in the year ahead, state officials
said they would prioritize programs aimed at improving air
quality in disadvantaged communities, providing safe and
affordable drinking water and improving forest health
and fire protection.
My colleagues and I worked with Assemblymember Rudy Salas
(D-Bakersfield), to craft AB 2642, which will create the
Multibenefit Land Conversion Incentive Program… This new

landowners who voluntarily repurpose their agricultural land to
other less water-intensive uses for a minimum of 10 years.
The Round Valley Indian Tribes, California Trout, Humboldy
County, the Mendocino Inland Water and Power Commission and
Sonoma Water have formed a group called the Two-Basin
Partnership and announced the filing of a feasibility report
with FERC on Wednesday.
This interdisciplinary study by plant biologists and physicists
is important because it potentially explains how plants take up
water in very dry soil — such as drought-tolerant plants in
Southern California and in the desert — and survive, said Cal
State Fullerton plant biologist H. Jochen Schenk, a co-author
of the paper.
For decades, sediment buildup in California’s Butano Creek
caused an array of issues for both fish and people. It flooded
roads and local communities, prevented steelhead and coho
salmon from migrating, and contributed to substantial die-offs
of fish. In October 2019, the NOAA Restoration Center and
partners finished a $7 million effort to remove the sediment
and restore the creek.
A partnership of numerous Northern California agencies intends

fully visible, into the still water.
An intense, long and dangerous fire season is projected.
Degraded north state watersheds threaten California’s water
supply and reliability, and northern rural counties rank among
the highest in the nation for unemployment. This combination of
risks is daunting, but if addressed together can yield benefits
and outcomes far greater than addressing each problem
Following passage of SGMA, The Nature Conservancy received a
$1.8 million Conservation Innovation Grant from USDA’s Natural
Resources Conservation Service to develop the Fox Canyon Water
Market. TNC, supported by project partners Fox Canyon
Groundwater Management Agency and California Lutheran
University, sought to establish a market-driven approach to
reduce groundwater pumping.
All animals leave traces of genetic material in their
environment, and for those organisms living in water, this
means their DNA is constantly being shed into the rivers or
lakes where they reside. Like something out of Star Trek,
scientists can essentially scan for lifeforms by filtering this
environmental DNA (eDNA) out of the water and utilizing
molecular techniques to either detect a certain species or to
assess the composition of the entire aquatic community.
The University’s Adrian Harpold recently led a team in
developing a modeling tool to focus on the issue of water
quantity. The tool predicts how different approaches to
thinning the forest impact snowpack accumulation in Lake Tahoe,
which controls how much water is available for downstream
communities such as Reno.
The USDA’s Natural Resources Conservation Service announced
today the availability of up to $5 million for wetland
mitigation banks. This funding through the Wetland Mitigation
Banking Program is available to help conservation partners
develop or establish mitigation banks to help agricultural
producers maintain eligibility for USDA programs.
A major response to the state’s biodiversity challenge has been
the California Biodiversity Initiative of 2018, which was
supported by Governor Brown and continues to be supported by
Governor Newsom. … However, it also has a major flaw: it is
so focused on terrestrial ecosystems and native plants that it
overlooks the needs of native aquatic (freshwater) species,
habitats, and ecosystems. California’s aquatic biodiversity is
particularly imperiled, as it is worldwide…
The Truckee Town Council has approved a resolution to accept

The U.S. Department of Interior started a water experiment
along the Colorado Friday, May 1, at the Glen Canyon Dam,
located near Page Arizona. The experiment is meant to improve
the egg-laying conditions for insects that live at least some
part of their lives in the water, which are the primary food
source for endangered Colorado River fish as well as native
For us, better science is the only path that can achieve those
two important goals. Unfortunately, as the state completed its
new permitting effort at the end of March, a decade of research
was largely ignored in favor of political objectives that

The Court decision introduces the concept of a “functional
equivalent of a direct discharge” as a guideline for when a
point source discharge must obtain a permit. It cites the case
of an injection well receiving pollutant discharge that then
travels a few feet through groundwater into navigable waters as
a clear case of “functional equivalent” to direct discharge.
