California’s two primary salmon species, Coho and Chinook, have
experienced significant declines from historical populations.
Of particular importance is the Chinook salmon because the
species supports commercial fishing and related jobs and economic
activities at fish hatcheries.
The decline in salmon numbers is attributed to a variety of
manmade and natural factors including drought, habitat
destruction, water diversions, migratory obstacles created by
local, state and federal water projects, over-fishing,
unfavorable ocean conditions, pollution and introduced predator
species. Wetlands have also been drained and diked; dams have
blocked salmon from reaching historic spawning grounds.
Years of declining populations represent a significant economic
loss and have led to federally mandated salmon restoration plans
that complicate water diversions and conveyance for agriculture
and other uses.
The Pacific Fisheries Management Council released estimates for
the number of chinook salmon that returned from the Pacific
Ocean in the fall to spawn in rivers where they were born or
released from hatcheries.
In the Consolidated Salmonid Cases, the Eastern District Court
of California reviewed a Biological Opinion (“BiOp”) issued in
2009 by the National Marine Fisheries Service (“NMFS”) that
placed restrictions on the Projects’ [Central Valley Project
and State Water Project] operations to protect endangered
A multi-agency partnership, involving state and local agencies,
this week finished inspections of 14 private properties with
active marijuana grow operations along Sproul Creek within the
Eel River watershed.
Looking back on 2014, it’s hard not to feel despair for
California salmon. … There was, however, a startling
exception to the run of bad salmon news. On the Shasta River, a
lifeline for Siskiyou County cattle ranchers, more than 18,000
fall-run Chinook salmon returned from the ocean. That’s more
than double the return from the previous fall.
Scientists from the U.S. Geological Survey and Washington State
University have discovered that endangered Chinook salmon can
be detected accurately from DNA they release into the
environment. The results are part of a special issue of the
journal Biological Conservation on use of environmental DNA to
inform conservation and management of aquatic species.
The lake of [Jay] Hall’s memory is dead, its salmon all but
vanished in the past decade – a collapse so swift that
fisheries biologists have likened it to driving off a cliff.
For a brief few decades, those biologists had turned this Great
Lake into a Pacific chinook factory, taking a wildly popular
sport fish from faraway ocean waters and setting it loose to
gorge upon the swarms of invasive alewives that had decimated
native fish species.
The bonanza of rain over the last week has boosted Marin’s
totals to above average, filled reservoirs and has allowed
endangered coho salmon to make their way back to local streams
sooner than normal. … And the rain is far from over with more
predicted for the weekend and early next week.
Crews are out working in the Sacramento River in Redding this
week repairing a side channel they hope will soon be filled
with spawning salmon. But the workers aren’t with one of the
state or federal agencies charged with managing fish and
wildlife. Instead, the Glenn-Colusa Irrigation District out of
Willows is spending about $250,000 to improve salmon habitat in
The cherished coho salmon that historically wriggled their way
past beachgoers up Redwood Creek into Muir Woods vanished this
year and are now on the verge of extinction, prompting a
last-ditch attempt by fisheries biologists to save the
genetically unique species.
On a recent day after a rainstorm, several dozen fall-run
Chinook salmon trying to migrate upstream in Auburn Ravine
found their progress frustrated. Efforts to complete their long
spawning run from the Pacific Ocean were halted by a small dam
on the outskirts of Lincoln.
The peace and quiet of the moment is suddenly broken by a
splash in the middle of the river. It’s the sound of fall run
Chinook salmon returning to the San Joaquin, bringing with them
the foundation for new life and a cause for celebration.
Just hours into the experiment, the prognosis was grim for
salmon that had been submerged in rain runoff collected from
one of Seattle’s busiest highways. … The research being
conducted by scientists with NOAA, Washington State University
and U.S. Fish and Wildlife offers a promising solution to
stormwater pollution, a major problem for Puget Sound and other
streams and lakes in the nation.
A miraculous thing happens each fall in the Sacramento Valley,
and it’s not the end of 100-degree weather: Salmon return to
the area’s rivers and creeks. One hundred miles from the
Pacific Ocean, the valley hosts one of the largest annual
salmon spawning runs in America.
For decades, California’s management and restoration of salmon
and trout populations have focused on principles rooted in
coastal redwood streams, mostly fed by rainfall runoff. These
concepts portray ideal salmonid habitat as deep pools, shallow
riffles and “large woody debris,” such as fallen trees and
limbs. Recent studies on spring-fed streams challenges this
The public will have a chance next week to witness the annual
spectacle of the American River salmon run. About 10:40 a.m. on
Nov. 3, the California Department of Fish and Wildlife will
open the fish ladder at Nimbus Hatchery on American River.
The Water Education Foundation’s popular Northern California
Tour features a diverse group of experts talking about
groundwater, flood management, the drought, water supplies,
agricultural challenges, and the latest on salmon restoration
efforts. The tour also includes a houseboat cruise on Lake
Shasta. … The tour travels the length of the Sacramento
Valley with visits to Oroville and Shasta dams.
A federal judge ruled Wednesday that a federal water agency did
not violate the law when it made special reservoir releases
last year to help salmon in Northern California’s Klamath River
survive the drought, rather than save it for farms.
The state Supreme Court on Wednesday allowed California
regulators to order farmers along the Russian River to reduce
cold-weather water sprays that have helped preserve their crops
while killing thousands of endangered salmon.
Construction crews that have spent more than two years
reconfiguring a mile-long stretch of Dry Creek outside

plans to restore endangered salmon and steelhead fish in
California’s Central Valley, including returning them to some
habitats where they were shut out decades ago by dams and other

Defense Council lawsuit against the Bureau of Reclamation and
Friant Water Users Authority that Friant Dam is required to
comply with a state law that requires enough water be released to
sustain downstream fish populations.
Fresh from the ocean, adult salmon struggle to swim hundreds of
miles upstream to spawn — and then die — in the same stream in
which they were born. For the salmon, the river-to-ocean,
ocean-to-river life cycle is nothing more than instinct. For
humans, it invites wonder. The cycle has prevailed for centuries,
yet as salmon populations have declined, the cycle has become a
source of conflict. Water users have seen their supplies reduced.
Fishermen have had their catch curtailed. Environmentalists have
pushed for more instream flows for fish.
