Federal
Government Intervenes in Butte Creek Salmon Disaster
by

The
worst ever die off of threatened spring-run chinooks on Butte Creek has
prompted a federal government agency, NOAA Fisheries, to press for a series of
actions to stop this from happening again in 2004. Unfortunately, the
government intervention was taken too late for this year’s run.
The
banks of Butte Creek, the most vibrant remaining spring chinook fishery in
California, have been littered since July with thousands of carcasses of salmon
that died before they were able to spawn. In a beautiful canyon where anglers
and environmentalists should be celebrating the return of a huge run, the
survivors of the fish kill are now spawning.
In
a disaster much worse than even the Klamath fish kill of 2002, the federal
government, fishery activists and DFG agree that the majority of wild
spring-run chinooks perished before spawning, although they disagree on the
exact numbers. The fish died from the same two diseases - Columnaris (bacterial
gill disease) and Ich - that killed spring chinooks on Butte Creek and fall
chinooks on the Klamath River last year.
Michael
E. Aceituno, Supervisor of Sacramento Area Office of NOAA Fisheries, estimated
the pre-spawning mortality to be “80 to 90 percent of the adult escapement” in
a letter to Magalie R. Salas, Office of the Secretary, Federal Energy
Regulatory Commission.
Emphasizing
the seriousness of the situation, Aceituno said, “The final pre-spawning
mortality estimate is likely to represent a significant proportion of the
entire population of the Central Valley spring-run Chinook Salmon Evolutionarily
Significant Unit (ESU).”
In
his letter, he requested FERC to initiate formal section 7 (a)(2) consultation
on these effects. Formal consultation is necessary any time a federal action
“may affect” species listed under the Endangered Species Act. Up to this point,
consultation has been done on an informal basis.
“We
believe that PG&E must take immediate steps if it is to avoid or minimize
any future episodes of high pre-spawning mortality levels of Central Valley
spring-run chinook salmon in Butte Creek,” he stated.
He
strongly urged FERC to direct PG&E to adopt 11 specific measures, most
regarding monitoring water temperatures and studies on how to manage the
hydroelectric plants best for salmon and steelhead.
NOAA
wants PG&E to analyze fish passage at Quartz Bowl and beyond (Centerville
Head Dam) immediately. It has also asked PG&E to do a risk assessment on
the flumes which regularly dump tons of sediment into the creek.
The
letter also recommended convening an upper Butte Creek science workshop to
review the status of existing information, identify relevant science/study
needs and make preliminary recommendations for operation alternatives and
facilities modifications.
Paul
Ward, DFG fishery biologist, dismissed the gravity of the fish kill and
estimates the pre-spawn mortality to be 11,200 fish and the live fish spawning
now to be 4,400.
“The
4400 fish that are now spawning is still more than over half of the combined
spring-run chinook populations of the other two tributaries, Mill and Deer
Creek,” said Ward. “The historic average of Butte Creek runs from 1967 to 1991
was 360 fish, with a high of 1300 fish. In contrast, the runs averaged 6,000 to
8,000 salmon over the past 8 years.”
Responding
to the NOAA letter, Ward said, “There is nothing requested in the letter that
is terribly different from what PG&E and DFG are already doing, other than
NOAA is requesting formal, rather than informal, consultation. There doesn’t
appear to be a lot that we could have done differently during the fish kill
this year. The Columnaris and Ich protozoa outbreak was caused by crowded, warm
water conditions.
However,
Allen Harthorn, board member of Friends of Butte Creek and fishing guide,
emphasized that the fish kill shouldn’t be taken lightly, since spring run
chinook are a listed species under the Endangered Species Act. Hawthorn
estimates that 12-15,000 fish died this summer before spawning.
“If
we had bald eagles, whales, or even fairy shrimp dying like this, people would
be up in arms about the deaths of listed species,” said Harthorn. “There is
simply no precedent for a listed species die off of this magnitude.”
He
also said that DFG and PG&E claims that the fish kill was caused by too
many fish in the creek is “ridiculous.”
“The
number of fish spawning in the creek this year has been greatly reduced from
1998,” he stated. “I’ve been documenting salmon spawning in the creek each
year. Whereas there were 20 redds (nests) below my house in Butte Creek Canyon
in 1998, today there are only 2 redds.”
Friends
of Butte Creek applauded the federal intervention. “After this year’s fish kill, NOAA Fisheries has stepped up to
the plate and asked for immediate action,” said Harthorn. “This is a huge step
forward in getting the ass-backward management of Butte Creek straightened
out.”
In
addition, the Friends have asked FERC to immediately increase the flow to 80
cfs and maintain the entire flow of Butte Creek and the West Branch Feather
River water (total 125 cfs) in the bypass reach all summer.
“This
would mean shutting down the Centerville Powerhouse all summer,” said Hawthorn.
“This would provide the best refugia from the summer heat in the highest
reaches, which is the only logical, biological thing to do.”
Harthorn
noted that the electricity lost by shutting down Centerville Powerhouse in the
summer would be “a drop in the bucket,”
2.3 megawatts, while saving the largest spring chinook run in California. This
compares to the 18 megawatts provided by Desabla Powerhouse and the 35
megawatts provided by the Battle Creek hydroelectric facilities.
“If
PG&E increased the flow to 125 cfs, they would not only provide better
conditions for spring -run chinooks, but support much healthier steelhead runs
and probably support a winter run of chinooks,” he added. “When you increase
the flows, you increase the available habitat.”
PG&E
did not return my phone call, but Lisa Randle, PG&E spokesperson, in an
article in the Chico Enterprise Record on October 2, was quoted as saying,
“More data is needed to make decisions. All the agencies and PG&E will be
working toward that.”
Tens
of millions of dollars have been spent on passage and habitat improvements in
the Butte Creek watershed, so this year’s fish kill is a gigantic tragedy.
Nobody knows yet how successful the spawn of the remaining fish - stressed in
the warm water - will be. All of the hard work and money that people have put
into the creek’s restoration is being lost, due to inaction by the Department
of Fish and Game and PG&E. I applaud the intervention by NOAA Fisheries.
Please
write letters of support to FERC for the NOAA recommendations. Write Magalie R.
Salas, Office of the Secretary, Docket Room, Federal Energy Regulatory
Commission, 888 First Street, N.E., Room 1A, East, Washington, D.C. 20002.
