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…
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
intentions … comes less than 24 hours after state lawmakers
passed the sweeping legislation.
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.
It didn’t take long for the completion of the Drought

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.
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.
The tropical Pacific Ocean probably won’t be particularly warm
or cool this winter, climatologists said Thursday, depriving
forecasters of their best clue to how much snow will pile up in
the Cascade Range and the rest of the Northwest.
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 agency … says it’s “open to the concept” of allowing the
public access to the park-like grounds with decorative lagoons,
waterfalls, palm trees and walking paths. But there are several
notable caveats, including that it won’t pay a dime for making
the property accessible and that such a development wouldn’t
interfere with operations.
Our fabricators recently constructed two custom weirs
commissioned by the U.S. Fish & Wildlife Service’s Lahontan

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
directly affect landowners and businesses in California. State
regulators in April passed a sweeping wetlands policy that
secured state oversight of California’s waterways…
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 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.
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.
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.
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.
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.
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.

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.

California has long been a top producer of oil. But that may
change. Some hope that change will accelerate under Gov. Gavin
Newsom, who has called for a decrease in the demand and supply
of fossil fuels. A recent massive spill in Chevron’s Cymric
oilfield in Kern County, about 35 miles west of Bakersfield,
prompted a major regulatory shakeup and could bolster that
A piece of Riverside history could be revived if Councilman
Steve Adams can get the city to refill Hole Lake, an irrigation
and recreation reservoir for 60 years that’s now full of trees
and plants and, in some spots, trash and homeless camps.
Before electric refrigeration brought cheap and available ice
in the early 20th century, ice was harvested along Truckee’s
lakes and rivers. Truckee’s cold mountain air and readily
available clear streams created an ideal environment for ice
companies to create and harvest ice.
A couple of weeks ago, I wrote an article in which I — perhaps
cavalierly — described Los Angeles as a desert. … There was a
small part of me that raised a red flag as I pounded the words
into my keyboard. Is L.A. a desert, though? I thought. Haven’t
I also heard that it isn’t?
The idea of conserving the marsh was not popular with most of
the residents and elected officials, and the McCoys were
frequent targets of threats and harassment. It was a rough and
tumble fight and there was a lot of money at stake. Ignoring
personal risk, the McCoys launched their campaign to secure the
The majestic beauty of the Sierra
Nevada forest is awe-inspiring, but beneath the dazzling blue
sky, there is a problem: A century of fire suppression and
logging practices have left trees too close together. Millions of
trees have died, stricken by drought and beetle infestation.
Combined with a forest floor cluttered with dry brush and debris,
it’s a wildfire waiting to happen.
Fires devastate the Sierra watersheds upon which millions of
Californians depend — scorching the ground, unleashing a
battering ram of debris and turning hillsides into gelatinous,
Commercial salmon catches have surpassed official preseason
forecasts by about 50%, said Kandice Morgenstern, a marine
scientist with the California Department of Fish and Wildlife.
Harvests have been particularly strong in Morro Bay, Monterey
and San Francisco, but weaker along California’s northern
Federal scientists pulled no punches in their report: The Trump
administration’s plan to send more water to San Joaquin Valley
farmers would force critically endangered California salmon
even closer to extinction, and starve a struggling population
of West Coast killer whales.
More than 60 elected officials and environmental and community
groups throughout the Bay Area are urging Redwood City
officials to reject proposals to develop the Cargill salt ponds
and rather have them restored as wetlands.
A new legislative audit has concluded Washington County water
bosses will likely be able to generate sufficient revenue to
pay the massive costs of building and operating the proposed
Lake Powell pipeline, but only through large fee, rate and tax
increases and if the county triples its population during the
next 50 years.
The Lake County Board of Supervisors approved an amended
resolution Tuesday that will open the door for Lake County to
join a group vying to take over responsibility for the Potter
Valley hydroelectric project.
“These are federal lands, and they are being systematically
destroyed through clear-cutting, stream diversion, chemicals
and pesticides,” said U.S. Atty. McGregor Scott at a news
conference, where he was joined by federal, state and local
officials who were part of the investigation. “It’s a vitally
The successes and failures of Australia’s recent reform of the
Murray-Darling Basin hold valuable lessons for policy makers in
California and elsewhere who are likely to grapple with the
environmental repercussions of extreme drought in the future.
A panel of experts discuss how reactivating the floodplains can
provide habitat and food for native fish and for migrating
birds, and highlights the many projects and opportunities in
the Sacramento Valley.
Finding a way to deal with the wastewater produced by a town
full of people is a challenge, one that’s forced the
McKinleyville Community Services District to find some creative
solutions. Officials are touting the emerging solution as a
win-win, a cutting-edge project that will serve the district’s
needs at minimal cost to ratepayers while also helping the
For a moment as columns of sunlight drifted through the pines
with the cobalt surface of Lake Tahoe in the background, it
seemed as though the partisan rancor so characteristic of this
political moment might temporarily evaporate. But such
congeniality was short lived, if it ever lived at all.
The plan affecting Sacramento River tributaries has not been
released, but water-resource managers in the region said they
have been collaborating with government agencies and
environmental groups to develop voluntary agreements that would
accomplish the goals of the state board’s flows-only
The headwaters of Blue Creek is also among the tribe’s most
sacred sites, said Gene Brundin, a member of the tribe’s
cultural committee. The stream begins at a place called Elk
Valley near Chimney Rock and its cold water ensures the
viability of the salmon runs, he said.
There is a legendary loop sitting in the Shasta-Cascade of
Northern California that includes 13 incredible waterfalls to
visit. Realistically, you could accomplish this entire loop in
just two to three days, and see some of the world’s finest
waterfalls right here in NorCal.
The California Department of Fish and Wildlife has increasingly
cracked down on commercial boat operators who escort passengers
into MPAs to illegally catch everything from rockfish to bass
to yellowtail. Wardens issued 1,053 warnings and 686 citations
for illegal fishing in the protected areas in 2017, according
to the agency’s most recently available data. That’s up
dramatically from 2013, when wardens gave out just 396 warnings
and issued 327 citations.
Law enforcement officials on Tuesday announced a major
operation underway targeting illegal marijuana-growing sites in
the Sierra Nevada allegedly being operated by Mexican citizens
who are using a pesticide banned in the United States.
Lake Temescal in Upper Rockridge sits atop the Hayward Fault,
which passes underneath the right abutment of the manmade
lake’s aged dam. Experts agree that creep has been observed
near Lake Temescal Dam, but disagree on whether this indicates
the area is at risk of suffering major damage during a strong
Outside the walls of the lab lies an environment increasingly
unfit for fish like delta smelt. The Sacramento-San Joaquin
Delta, some 40 miles inland from the San Francisco Bay, is a
1,100-square-mile tidal marsh that for millennia teemed with
salmon, shellfish, tule elk, deer, and waterfowl — all of which
supported a Native American population of about 300,000 people.
Just a few months after completing the Drought Contingency Plan
for the Colorado River states, water managers in the southwest
will likely have to implement it starting in 2020. That’s
according to new projections for the levels of key reservoirs
in the southwestern river basin, and Arizona is first in line
to take water cutbacks.
The July 1 assessment, obtained by The Times, outlines how
proposed changes in government water operations would harm
several species protected by the Endangered Species Act,
including perilously low populations of winter-run salmon, as
well as steelhead trout and killer whales, which feed on
There is something about a swimming hole that implies
elusiveness. Compare it to the beach, which, at least in
California, one could reach from just about anywhere by heading
west: The coast is a line, but a swimming hole is a dot on the
map, a point in space and time.
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.
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.
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
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.
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).”
Ask around and many agree: just the sight of water in the Kern
River on a hot day has its own cooling effect. … Lucky for
us, water is expected to remain in the river for weeks to come,
though it won’t be quite as deep and full as it has been in the
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
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.
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
both species and ensure other water users would benefit as
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,

The study, published Wednesday in the scientific journal PLOS
One, documented dramatic decreases in wetland habitat around
San Francisco Bay, the Sacramento-San Joaquin River Delta and
nearly 450 other bays, lagoons, river deltas and coastal creek
mouths throughout the West.
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.
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.
In a joint statement, the local utility providers announced
that the Chili Bar Hydroelectric Project — a dam, reservoir,
spillway and powerhouse that generates electricity north of
Placerville on the South Fork of the American River — would be
changing hands after SMUD’s board of directors voted Thursday
evening to greenlight the purchase.
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
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.
A dozen conservationists gathered eagerly around the edges of
some shallow pools above a waterfall in the Angeles National

The California Tahoe Conservancy had planned to get started on
their $9 million, multi-stage Upper Truckee River project to
restore and enhance over 500 acres of floodplain this fall, but
that has been postponed until 2020. They will be redirecting
the Upper Truckee River flows to a historical network of
channels through the current Marsh while creating new channels
for the river in the vicinity of the Silverwood neighborhood.
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.
With the last drought in the rearview and the next one
inevitable, the damaging run on groundwater has state water
agencies and lawmakers mulling whether to spend hundreds of
millions to patch up a federally owned canal. But critics say
doing so would amount to a clear bailout for the state’s
A decade’s worth of junk including cars, refrigerators and even
goat carcasses that were illegally dumped into a West Marin

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.
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
cross the lake. … It’s not fish or Tahoe Tessie; it’s a horde
of tiny mysis shrimp, which researchers think have been making
the lake murkier since they were introduced in the 1960s.
On Monday, Aug. 19, the Yurok Tribe, Green Diamond Resource
Company and Western Rivers Conservancy will celebrate a
decade-long, hard-won effort to preserve and place into tribal
ownership approximately 50,000 acres of forest surrounding four
salmon sustaining streams, including Blue Creek, according to
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
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.
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

An unprecedented survey has revealed the loss of about 85
percent of historical tidal wetlands in California, Oregon, and
Washington. The report, published today in PLOS ONE, also
highlights forgotten estuary acreage that might now be targeted
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.
For five decades, PG&E paid for and operated the Colgate
Powerhouse in exchange for the revenue generated by the
hydroelectric generation. But now, instead of tens of millions
of dollars flowing out to the utility, that agreement has
expired and the revenue, potentially as much as $30 million per
year, is flowing back into the Yuba Water Agency.
Guests of Siren Island, a two-tiered wooden isle affixed with
four spindly maple tree branches, were relaxing in the
late-afternoon sun on the calm waters of the Sacramento-San
Joaquin River Delta. They took turns plunging their hands into
a steel basin of black lagoon mud then spreading it on one
another’s skin — limbs, torsos and faces.
