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.
At this point in the Sacramento River restoration game, one big
fix will not change the outlook for endangered and threatened
salmon. However, fish scientist Dave Vogel hopes that a series
of smaller fixes will make a big difference.
Five years of drought have severely taxed California’s rivers,
reservoirs and groundwater. The Sacramento-San Joaquin Delta –
the hub of California’s water supply, an agricultural center
and a crucial ecological resource – hasn’t been immune from the
impacts of the prolonged drought.
At this free one-day briefing in Stockton
on Oct. 25, keynote speaker Jay Lund, Director of the UC Center
for Watershed Sciences, and other experts will
discuss the drought’s effects on the Delta.
Other confirmed speakers include Delta Watermaster Michael
Patrick George, Michelle Banonis, Manager of the Bureau of
Reclamation’s Bay-Delta Office, Michael Dettinger, senior
scientist and research hydrologist at USGS, and Peter Moyle, one
of the foremost experts on California’s freshwater fish.

Less than 50 miles northeast of Chico, California, begins the
93-mile Butte Creek – a tributary of the Sacramento River. It is named
after Butte County, which was in turn named for the nearby
volcanic plateaus, or “buttes,” and travels through a massive
canyon on its way southwest to the Sacramento Valley.
As a watershed, it drains about 800 square miles, both for
agricultural and residential use. The upper watershed is
dominated by forests, while the lower watershed is primarily
The Bureau of Reclamation released water from the Trinity
Reservoir early Thursday morning to the lower Klamath River to

After nearly a month in port, local fishermen are once again
heading out to sea in search of the highly prized king salmon.
Also known as Chinook, it’s a sleek, silver fish that boasts a
high oil content, sweet flavor and a deep orange color due to
its fat-laden diet of krill, anchovies and squid.
From a Hoopa Valley Tribe press release: Today, the Hoopa
Valley Tribe (HVT) filed its lawsuit against the federal
government for violations of Endangered Species Act (ESA)
regarding its management actions on the Klamath River,
California’s second largest river system.
As Operation Yurok — which the Yurok Tribe carries out each
summer with help from local, state and national agencies —
continues this week, Yurok Tribe Chairman Thomas P. O’Rourke
Sr. said Wednesday the tribe may carry out similar raids later
this year. … Illegal diversion of water from stream and
creeks lead to less water for the Yurok people and the salmon
that live and spawn in the rivers.
While conditions on the Klamath River are looking more
favorable for fish compared to recent years of drought and
disease, North Coast researchers and tribes are not expecting
fall-run salmon to have an easy journey.

alleged Endangered Species Act violations on the Klamath River
after a group of environmental and fishing organizations filed
a notice of intent to sue this week.
Whether the temperature management of the runoff of Northern
California water reservoirs, including Shasta Dam, results in
improved survivability of endangered fish or uncertainty for
human water users was debated at a House Natural Resources
subcommittee hearing Tuesday.
A bill passed by U.S. House of Representatives seeks to limit
predator fish, such as striped bass, in the Sacramento-San
Joaquin Delta to aid struggling salmon populations. But

to fish for salmon, but for there to be salmon to catch — a
ruling that affirms the duty of the United States to protect
the habitat of the prized fish under treaties dating back more
than 150 years.
The Karuk and Yurok tribes are planning to sue two federal
agencies for what they perceive to be a failure to protect
threatened juvenile coho salmon from deadly parasitic outbreaks

the costs and pace of switching from fossil fuels to
renewables. The discussion, however, should widen to include
examination of programs favored by environmentalists and
governments to preserve species.
Visitors to the Feather River Fish Hatchery will find new signs
with updated information. The signs replace displays that were
erected when the hatchery first opened in 1967, according to
Penny Crawshaw, fish hatchery manager.
Recent high tides and brief mid-September rains gave some Eel
