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

The U.S. National Science Foundation-funded study … found
that agrochemicals can increase transmission of the schistosome
worm in myriad ways: by directly affecting survival of the
waterborne parasite itself; by decimating aquatic predators
that feed on snails that carry the parasite; and by altering
the composition of algae in the water, which provides a major
food source for snails.
On July 16, 2020, the Council on Environmental Quality (CEQ)

The legislation, H.R. 1957, would provide the Land and Water
Conservation Fund with $900 million annually — the first time
the program has ever been guaranteed full, yearly funding since
its creation in 1964. It also would establish a trust fund to
start winding down some of a $20 billion backlog of deferred
maintenance projects at national parks and on public lands.
A century ago, the Sacramento-San Joaquin Delta was a massive
wetland habitat. The construction of levees over the past 100
years has dried out these wetlands and converted them into
farmland, eliminating 95 percent of this important aquatic
habitat for fish. But scientists are finding out that given the
right conditions, nature can reclaim itself.
The nearly $2-billion EchoWater project aims to meet a 2010

As coronavirus infections and deaths continue to rise
throughout the United States, state officials are fighting a
battle against a separate outbreak that has killed up to 60,000
fish at the Mojave River Hatchery. The culprit, a bacteria
known as Lactococcus garvieae, has never before been
seen in the state…
Rollbacks of the Clean Water Act and the executive order to
suspend the National Environmental Policy Act are meant to save
costs and cut red tape. However, Jeremy Schewe, professional
wetland scientist, explains these efforts will ultimately lead
to far greater expense to business, society, and the planet,
especially when combined with the House proposed infrastructure
Headwater forests are critical to California’s water supply, a
fact made plain by recent state funding
decisions…California’s water storage is concentrated in the
alpine snowpack that accumulates during the wet season and

Historically, Colorado has had a love-hate relationship with
the 1968 Wild & Scenic Rivers Act. While we have unarguably
some of the wildest and most scenic rivers in America, Colorado
has only one such designated section – the Cache la Poudre
River above the city of Ft. Collins. New Jersey, a much smaller
state with many fewer river miles, has five designated Wild &
Studies conducted in multiple countries in recent months have
detected the novel coronavirus, SARS-CoV-2, in treated and

evidence of a person contracting the virus through wastewater
or swimming areas.
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.
California Attorney General Xavier Becerra, Maryland Attorney
General Brian Frosh, and Massachusetts Attorney General Maura
Healey today led a multistate coalition in expressing
opposition to President Trump’s recently signed executive order
instructing federal agencies to use emergency authority to
bypass critical environmental review and permitting processes
for infrastructure projects.
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.
Within weeks of Bay Area Concrete losing its battle before the
Hayward Planning Commission, PG&E had hired the company to
build and run a dump outside of Paradise, 180 miles to the
north. Trucks began dumping potentially toxic slurry at the
disposal site, which did not require environmental review as an
emergency project and helped speed cleanup operations.
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.
The summer’s high temperatures have contributed to an algal
bloom that’s impacting Clear Lake, with recent testing of 30
sites on the lake finding concerning levels of cyanotoxin. On
Thursday, Lake County Water Resources reported on the lake-wide
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.
Russell Barabe is a coldwater fisheries biologist based out of
CDFW’s South Coast Region office in San Diego. … A Master’s
degree in fisheries biology at Mississippi State University put
him on the path to becoming a CDFW biologist, where he’s been

The historic lighthouse at Rubicon Point was born out of
organized advocacy work in the early 1900s. The Lake Tahoe
Protective Association formed in response to a proposal to cut
the rim of Lake Tahoe at the Truckee River. The proposal was
floated by the Truckee River General Electric Company in 1912
as a means to keep water flowing out of Tahoe even when the
lake level dipped too low.
The state of California, city of Imperial Beach, and the
Surfrider Foundation have agreed to a 12-month stay in

On June 24, 2020, the United States District Court for the
Eastern District of California denied the preliminary
injunctive relief requested by a coalition of fishery and
environmental groups regarding the U.S. Bureau of Reclamation’s
operations of Shasta Dam and Reservoir, and related temperature
management actions on the upper Sacramento River.

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
season by spreading large flows across the floodplain. The pond
and plug treatment improves water quality, soil moisture, and
wetland vegetation – improvements that are extremely beneficial
to birds and other wildlife.
he Northern Sierra Partnership, a coalition of land trusts
based in Palo Alto and funded in large part with donations from

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.
The project — managed jointly by California Division of Fish

The Environmental Protection Agency has again been sued over
its rollback of Obama-era waterway protections. On Thursday,
the Environmental Integrity Project, on behalf of four other
environmental groups, sued the agency, claiming that the new
rule conflicts with the Clean Water Act and “disregards”
science “without any rational, let alone ‘reasonable,’
The Delta is changing much faster than we can respond to, and
if we want to start to get ahead of things, we need to think
about what changes lie ahead and what managers and decision
makers will need to manage those changes. That was the topic
for the second Science Needs Workshop hosted by the Delta
Science Program which brought together Jennifer Pierre with the
State Water Contractors, Paul Souza with the US Fish and
Wildlife Service, and Campbell Ingram with the Delta
On June 18, 2020, the Third District Court of Appeal affirmed
the lower court’s determination that the State Water Resources
Control Board lawfully adopted emergency regulations and

severe and persistent drought conditions.
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
Groundwater provides nearly 40% of the water used by
California’s farms and cities, and significantly more in dry
years. But what is groundwater? In this post based on the first
segment of the UC Davis shortcourse on groundwater, Dr. Thomas
Harter provides a basic understanding of groundwater – what it
is, how much groundwater is out there, how fast groundwater
moves, and where it comes from and where it goes.
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
flooding the area, but it’s one of several mitigation projects
that have taken flack for progressing so slowly.
It shouldn’t come as a surprise that the farm itself has become
part of the landscape that millions of birds rely on. Cannon
Michael, president of Bowles Farming Co., has partnered with
Audubon over the last decade to support birds on his farm by
restoring corridors and habitat, and finding new ways to manage
crops to protect wildlife. You know a farmer is serious about
birds when their Instagram includes highlights like the “Birds
of Bowles Farming”.
Last week, on the flanks of Mount Lassen, the partnership of
the Western Rivers Conservancy and the Lassen National Forest
completed a project that protects a crucial 1,150-acre
property, and a significant branch of South Fork Antelope
Creek, a rare stronghold for salmon and steelhead in the
Sacramento River system.
Major California cities say they’ll use their share of a $650
million settlement to clean up the now-banned chemical PCB from
bays, lakes and other waterways polluted for decades. The giant
chemical company Monsanto announced a tentative agreement
Wednesday with government entities that had filed suit since
2015 over waterways and estuaries they say were polluted.
In an innovative and cross-disciplinary remote-sensing
approach, engineering Professor Joshua Viers and colleagues aim

After being docked for three months due to COVID-19
restrictions, the Department of Water Resources relaunched its
research vessel monitoring program, the Sentinel. It was the
first time since the 1970s that DWR didn’t have a monitoring
vessel taking field samples in the waters of the Sacramento-San
Joaquin Delta and San Francisco Estuaries.
The creation of the Council was, in many ways, an experiment in
governance by the California State Legislature and
Schwarzenegger administration to address years of gridlock over
how to manage the Delta’s limited natural resources and chart a
science-based path forward for future management. After ten
years with the Council, I can say, with conviction, the
experiment is working.
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.”
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 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,
had burned 186,086 acres in the Tonto National Forest as of
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
nutrients are likely to increase in concentration in areas
affected by wildfire in the western U.S., and whether the use
of fire retardants may exacerbate the situation.
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 return to normalcy. But that’s not what we need. We must come
out of this pandemic looking to address other looming crises.
Our unsustainable agricultural system, along with climate
change, are at the top of the list.
With dry conditions resulting in low flows and threatening the
survival of coho salmon, the State Water Board today sent
notices of water unavailability to110 junior water right
holders in the Scott River basin in Siskiyou County, urging
them to stop diverting.
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.
While these remarkable giants have been only a distant memory
in most of their range, recently, fish carrying the ancestral
genes of Pyramid Lake Lahontan cutthroat trout migrated to the
waters of the Truckee River in 2014 to spawn for the first time
in 80 years. The return of these fish … represents the
culmination of years of conservation efforts by local, state,
and federal agencies, as well as the Pyramid Lake Paiute Tribe.
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
individuals remain. But a project jointly developed by the
Service, the California Department of Fish and Wildlife, Spring
Rivers Ecological Sciences, and the Pacific Gas and Electric
Company could change the fate of the crayfish.
As winter rains intensify with climate change, flooding will
worsen in Santa Clara County, the Bay Area’s largest by
population… The Coyote Creek system — 1,500 miles of
waterways that drain a 350-square-mile watershed — connects
half a dozen elements that are key to climate adaptation, from
reservoirs to creek confluences to the Bay shore.
Saying in a project description that there is a demand for
high-quality construction supplies, … the company proposes to

Mount Shasta is a community that prides itself on clean water.
In the past when water-related issues have come before City
Council, meetings are often crowded to the point of
overflowing. It is surprising, then, that one of the most
important water topics in our city receives so little

Roland Knapp, research biologist at the University of
California Sierra Nevada Aquatic Laboratory, explained that a
fish-less habitat along with increased resistance to chytrid
fungus can allow populations to rebound and increase. Knapp’s
research findings have shown the frogs being able to adapt to
the disease over time. … “I have a lot of hope. I wouldn’t
have said that 10 years ago.”
In October 2019, the Public Policy Institute of California
(PPIC) released the report, Priorities for California’s Water,

The California Department of Fish and Wildlife is urging
anglers and other recreational water users to be vigilant about
checking for harmful freshwater algal blooms, also called HABs,
while out enjoying California’s lakes, reservoirs, rivers,
streams and creeks this year.
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 largest in the trust’s portfolio. Its terrain ranges from
lake to valley oak woodland with everything from native
wetland, freshwater marsh and upland pasture included. The
property is partially bordered by Manning Creek, an important
breeding ground for an endemic and threatened fish species, the
Clear Lake hitch.
Burrowing owl homes maintained by the Otay Water District
received a modern makeover this year. As part of its ongoing
environmental mitigation efforts, the District managed
construction of new nesting burrows to encourage breeding. Ten
acres of the 240-acre, District-owned San Miguel Habitat
Management Area reserve and mitigation bank in eastern Chula
Vista is a dedicated native grasslands area where the new
artificial burrows are located.
In a rare display of bipartisanship, the U.S. Senate has passed
a sweeping public lands package that both addresses the
ballooning maintenance backlog at national parks and provides
full, permanent funding for the popular Land and Water
Conservation Fund, a program established in 1964 to protect
natural areas and water resources.
The California legislature voted Monday to keep the Salton Sea
in its budget proposal sent to Governor Gavin Newsom.
Assemblymember Eduardo Garcia said he’s pleased the legislature
found a way to allocate some funding for the Salton Sea despite
the fiscal challenges created by the pandemic.
California’s top water regulator on Tuesday approved a
definition of microplastics in drinking water, setting the
stage for the state to investigate the extent of contamination
from the tiny plastics that have been found in fish, waterways,
and other habitats. … The action makes California the first
government in the world to define microplastics in a drinking
Nevada is in a new era of water management. As the driest state
in the nation, responsible and sustainable management of
Nevada’s limited water resources is the foremost priority of
the Nevada Division of Water Resources. As part of this
commitment, Monday the Nevada State Engineer issued Order No.
1309 for one of Nevada’s most important and unique hydrographic
basins called the Lower White River Flow System.
Beginning June 11, the Bureau released flows to help sustain
juvenile salmon, but it plans to provide only 16,000 of the
40,000-acre feet promised in the plan developed with the Yurok
Tribe, fishing groups and irrigators in March. And nearly a
month passed without augmented flows when young salmon were
being infected and dying from disease-causing parasites and 1.5
million hatchery fish were released and ready to pass through
the infection zone.
Supreme Court justices today declined to consider whether
moving — but not adding — rocks, sand and other debris within a
regulated waterway is subject to Clean Water Act restrictions.
The court’s decision not to take up the Eastern Oregon Mining
Association’s petition came as a disappointment for operators
that use suction dredge mining, an industrial process similar
to panning for gold in a river.
President Trump’s wall now stretches along 200 miles of
U.S.-Mexico borderland. Progress hasn’t slowed during the

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.
Aaron Thomas arrived back in Paradise Valley just in time to
christen the Ambiente Course, which proved a sort of launching
pad for all manner constructive, on-course experimentation. …
Thomas confirms the new design saves between 45 million and 55

That is the platform from which Thomas has worked these past
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
oversight, Agriculture Secretary Sonny Perdue told the U.S.
Forest Service Friday. His memo announced a “blueprint for

and services from the 193 million acres of forests, grasslands,
and wilderness areas it oversees.
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
