Fisheries biologist Don Chapman says the impacts of global warming on the region call for drastic action if Idaho's salmon are to survive
Fisheries biologist Don Chapman has been the main expert of the hydroelectric industry in the Pacific Northwest for decades, and has advocated against dam breaching. Now, he's changed his mind and says breaching must be on the table because of the impact that global warming and recent political decisions will have on fish populations. .
Fisheries biologist Don Chapman has been called the guru of salmon science in the Pacific Northwest. He's talking about breaching the four lower Snake dams in Washington. Those dams produce less than 5 percent of the region's federal power. Chapman says "let the river cleanse itself" after breaching dams.

Chapman, called the "guru" of salmon science in the Pacific
Northwest, wants to breach the four lower Snake dams in Washington. Those dams
produce less than 5 percent of the region's federal power — enough to meet
Seattle's needs — and allow barge shipping of grain and other goods from
Lewiston to Portland.
Breaching the dams is necessary, he said, because many residents value salmon
and want the fish to survive in harvestable numbers. Salmon represent the
region's wild heart and provide food and spiritual sustenance for Native
Americans and a fishing industry worth hundreds of millions of dollars.
Six years ago, Chapman led a minority that opposed breaching dams in the
face of an overwhelming majority of members of the Idaho Section of the
American Fisheries Society that said breaching the dams was necessary for
restoring salmon.
Earlier this year, Chapman filed a declaration on behalf of public power
companies challenging salmon advocates' plan to spill water over the dams to
help the salmon migration. So when the man whose opinion that business and
political leaders have rested their cases on for current salmon programs calls
for a major reassessment, people listen.
"When Don says it, you kind of stand up and take notice," said Chuck
Peven, fisheries program manager for the Chelan Public Utilities District in
Washington, which operates dams on the Columbia. "He's only an advocate
for the best science."
But Peven and other biologists who work in the utility industry aren't
ready to accept Chapman's argument.
"It's a nice story, but there are a lot of linkages here that need to be
examined thoroughly," said Al Georgi, a fisheries consultant who took
over Chapman's business when he retired seven years ago.
"He's the guru of salmon resource science here in the Pacific
Northwest and people must pay attention to what he has to say," Georgi
said.
Robert Lohn, Northwest Regional Director of the National Marine Fisheries
Service, is intrigued by Chapman's shift.
"I have a great deal of respect for him as a biologist and I would be
interested in understanding his reasoning," Lohn said.
Chapman said his current position is not just based on science but also
politics.
"After 50 years in fisheries, I take that privilege," he said.
Chapman said the Bush administration's decision that the dams don't jeopardize the survival of salmon because they were there at the time the fish were listed under the Endangered Species Act "is so contrary to logic and common sense that I feel offended."
Warming is at the heart of his argument
Data shows the temperature of the Columbia River at Bonneville Dam has
increased 1.5 degrees centigrade since 1938. Higher temperatures in the river
increase stress, predation and disease, especially in fall chinook that
migrate during summer.
Sockeye are migrating earlier to avoid the warm water, steelhead split their
migration to avoid the warm river.
Also, spring chinook and steelhead will be losing habitat in tributaries that
are warming, Chapman predicted, forcing them to move upstream. Finally, some
scientists are worried about the collapse of productivity of the North Pacific
ecosystem where salmon spend much of their lives.
"With warming, we are going to have to give salmon and steelhead in
Idaho every break possible if they are to survive," Chapman said.
The other trigger to his new view was U.S. District Judge James Redden's May
decision to strike down the Bush administration's plan for protecting salmon
from federal dams. Redden ordered federal dam operators to spill water over
the dams at a cost of $67 million this summer alone. The loss of that
hydropower revenue and perhaps even more in the spring, "reduces the
hydropower benefit of the lower Snake dams," Chapman said.
Chapman said Redden was wrong to order the spill, which reduced the number
of salmon barged, and forced more to survive the warmer river this summer.
Barging fish only benefits salmon in the driest years and not consistently, he
said.
Over the long run, dam breaching will be cheaper than making investments in
barging, fish bypass facilities and new technologies like removable spillway
weirs, Chapman said. Many hatcheries also can be closed once the dams are
gone.
Don't switch to fossil fuels
But before the dams should be breached, he said, railroads should be built
to replace barge shipping to reduce the use of fossil fuels.
He advocates the building of nuclear power plants and not natural gas or coal
plants to offset the lost electric power generation capacity. This would be
necessary, he said, because the region continues to grow rapidly.
"Advocates of breaching cannot responsibly propose fossil-fuel
substitution for lost hydropower," Chapman said. "I especially aim
that comment at fish biologists, who are trained in holistic ecology."
Chapman's opinion doesn't sway Owen Squires, director of the Rocky Mountain
Region for Pulp and Paperworkers Resource Council, who is active in the
Lewiston-based group Save our Dams.
"Breaching those dams is a radical, one-way step," Squires said.
"Once we do it, we can't reverse it."
But he agrees with Chapman on nuclear power and fossil fuels.
"If we had four nukes in the desert cranking out that power, part of the
argument would be mute," Squires said. "But the same people who want
us to breach the dams are the same people who want us to burn natural gas but
don't want us to drill for more gas."
Even with breaching, salmon harvest will have to be strictly limited, Chapman said. He advocates a cooperative fishery that allows tribal members to catch hatchery salmon as they return to Bonneville Dam. That would eliminate losses of endangered wild salmon caught in the nets of fisherman targeting more abundant species.
Less water would be needed from Idaho
One group that would benefit from breaching is southern Idaho's water
users, Chapman said. They currently send 427,000 acre-feet of water from
southern Idaho reservoirs down the Snake River to aid salmon migration. Less,
not more water, would be needed if the four dams were breached, he said.
However, Chapman would like to see some of the water used to irrigate the
benches and lands now covered by the reservoirs behind the four dams. The
irrigation would be used to anchor the silt with vegetation to reduce the
amount that would be carried downriver.
He would keep those lands in federal ownership as wildlife areas.
John Rosholt, a Twin Falls attorney who represents the major canal companies
serving southern Idaho, is a long-time friend of Chapman's who often has
called on his consulting services for his clients.
"With Don Chapman now taking this position, certainly, all people
concerned with the issue should re-examine the premises on which he's basing
it," Rosholt said.
Why Chapman's opinion is significant:
• Resume. He is one of the most senior, respected fisheries biologists in
the Pacific Northwest. He taught a generation of fisheries biologists at the
University of Idaho their trade before becoming a consultant for electric
utilities and others.
• Past position: Chapman was among the most prominent opponents to breaching
the four lower Snake dams in Washington and one of the strongest supporters
for the current fish bypass and collection systems at the dams.
Why breaching dams is under discussion now
• U.S. District Judge James Redden struck down the Bush administration's
plan for salmon and dams that ruled out breaching the four dams in Washington.
Many scientists say the only way to preserve salmon is to breach some of the
dams on the Columbia and Snake rivers.
• As Chapman pointed out, Redden's order to spill water over the dams to aid
salmon reduced the revenue from the dams by $67 million this summer alone. He
could order even more costly measures to aid salmon migration next spring,
which would make dam breaching more attractive economically as a way to
preserve the rest of the federal hydroelectric system in the Columbia Basin.
