YREKA, Calif. – Scientists reviewing federal
efforts to protect Klamath River coho salmon say
more attention needs to be given to summer water
temperatures. How the recommendation plays out
will be determined this winter as agencies revise
an Endangered Species Act biological opinion
already found wanting by a federal judge.
The National Research Council finding has
implications for irrigators in U.S. Bureau of
Reclamation’s Klamath Project astride the
California-Oregon border and for the Klamath Basin
Fisheries Task Force, a federal advisory group
that met here last week. Irrigation water supply
in average or below-average years is pinched in a
balancing act between downstream coho flows and
retention of Upper Klamath Lake water needed by
suckerfish also under ESA protection.
Coho is one of dozens of fish species that call
the Klamath home. The stream, more than 250 miles
from the ocean to headwaters in Oregon and in
California’s Trinity County, is best known for
chinook salmon and a sometimes-contentious
struggle over water, which in 2001 resulted in
non-delivery of irrigation water when a
drought-shortened supply was held for habitat of
ESA-protected fish.
The NRC report issued Oct. 21 says just calling
for water flow misses the mark for coho salmon.
They spend 14 to 18 months of their three-year
lives in fresh water, a stay interrupted by a year
or two in the Pacific Ocean.
Iron Gate Reservoir, farthest downstream of the
Klamath’s eight-plant hydroelectric system, is
well-known for heating water. Increasing summer
flow from Iron Gate makes a warmer river,
sometimes lethal for young coho.
“From a bioenergetic perspective, increasing
minimum (river) temperatures may be especially
unfavorable for coho,” says the report.
Before the 2004 irrigation season, NOAA Fisheries
and BuRec intend to revise coho biological
opinions. Most participants in last week’s task
force meeting had not reviewed full contents of
the NRC report.
Irma Lagomarsino, Northern California team leader
for NOAA Fisheries, told the task force on Oct. 22
that revisions will also address criticisms of the
biological opinion made earlier this year by a
federal judge who questioned anticipating water
supply from non-project irrigators and a BuRec
water banking plan.
The controversial biological opinion issued in
June 2002 dictates minimum downstream flows
delivered at PacifiCorp’s Iron Gate Dam. BuRec
said last year that it wanted to renegotiate the
opinion. U.S. Department of Interior delayed the
process until the NRC report was in hand. It
arrived less than 24 hours before the task force
began last week’s meetings in Yreka.
Chris Karas, deputy manager of the BuRec Klamath
Project, said work continues on the environmental
impact statement that covers project operations
through 2012. Public comment is extended until
December to allow consideration of the NRC report.
This week BuRec was scheduled to release another
draft of the proposed basinwide conservation plan
process. Officials hope it brings together upriver
and downriver interests, involving the entire
10-million-acre basin rather than placing the
burden for ESA compliance on the reclamation
project’s 200,000 acres of cropland. There’s also
a move to broaden management beyond fish currently
listed by the ESA. That’s another point made in
the NRC report.
“Think unified basin,” Karas said, urging a
central clearinghouse for all state and federal
water quality data and uniform standards for what
information is collected.
NOAA, after what Lagomarsino described as “a long
pause,” is back at work on recovery plans for the
Klamath coho and other coastal salmon under ESA
protection. She told the task force it will be
spring 2004 before the agency has goals for how
many fish represent a recovered population in
specific streams or parts of streams.
It’s a “different approach” from the state of
California’s coho protection plan, triggered
earlier this year by a separate listing made under
state law by the California Fish and Game
Commission. Craig Marst, leader of the state
fishery team for the Scott and Shasta rivers, said
California law requires his agency give permits
for 1,600 irrigation water diversions that might
be considered impacting coho habitat.
“Part of the thing slowing us down,” Marst said,
“is lack of data” on the amount of fish loss that
could occur as a result of those diversions.
The Klamath’s fall chinook salmon run is in full
swing and has already peaked in the lower river.
DFG’s Neil Manji said it appears migration in some
streams is perhaps a week or more slower than in
2002. The state hatchery at Iron Gate Dam, five
miles east of I-5 in Siskiyou County, counted
22,000 chinook through Oct. 20, up 1,000 from the
same week one year ago. But Manji said chinook
numbers are behind in major tributaries such as
the Shasta and Scott rivers.
“The run is delayed. They are there. They are
moving up,” Manji said.
The task force was established by the 1986 Klamath
Restoration Act and is charged with implementing
fishery restoration by 2006. Another advisory
committee launched by the same act, the Klamath
Fishery Management Council, faces an uncertain
future.
The House version of the 2004 federal budget
denies the council funding, a request made by Rep.
Wally Herger, R-Calif. The Senate has yet to act
on that part of the federal budget.
Phil Detrich, head of the U.S. Fish and Wildlife
Service Yreka office, said since the new federal
fiscal year began Oct. 1, he can’t spend any time
supporting council activities. They are mainly
concerned with technical details of commercial,
tribal and sport fishery quotas for Klamath River
anadromous fish.
