"(Removing the dams)
has been a long-held dream," said Troy Fletcher, lead negotiator on
settlement issues for the Yurok Tribe and a tribal member. "It's a
chance to restore our fishery."
PacifiCorp has not agreed
to pull its dams. The company is attempting to relicense the facilities
to keep operating for another 30-50 years. About $300 million in
spending would be required to make the dams more fish-friendly if they
are relicensed.
Stakeholders are
presently holding confidential meetings with PacifiCorp to try to reach
an agreement that makes business sense to the company and results in dam
removal.
Folks who live closest to
the dams are dismayed at the prospect. A number of citizens have voiced
their concern at

Dams out, algae out

say, increasing the overall health of salmon populations native to the

But biologists with the
Klamath Tribes, headquartered in Chiloquin, Ore., near the river's
headwaters, are confident that dam removal combined with habitat
restoration and fish reintroduction would indeed bring salmon back to
the Upper Basin to once again nourish the tribe.
"We want salmon to
get up here the best way they can. That's with dams out," said Jeff
Mitchell, a Klamath Tribes councilman. "Dams out gives us, I think,
the best long-term protection for those fish that we can achieve. In
addition, we have to think about what do we also need in the
Taking the dams out could
relieve the river of high concentrations of a blue-green algae known as
Microcystis aeruginosa. Under warm, still-water conditions, this algae
can form massive blooms and produce toxins.
During the warm summer
months, the blooms form on the surfaces of Copco and
Late last summer, algae
concentrations were higher than ever before in the lower river, and
present for a longer duration, said Ken Fetcho, interim program director
for the Yurok Tribe Environmental Program that monitors water quality on
the river and its tributaries.

Some fishermen reported
skin rashes after being in the Klamath, Fetcho said.
"The river just
turned green overnight," Fetcho said. "It's pretty clear to
the tribe that these two project reservoirs create conditions for algae
to thrive."

Preliminary go-ahead
The California Coastal
Conservancy initiated a series of studies to see if removal of the
Klamath dams was feasible, both in costs and actual demolition. The
agency worked with several consultant groups to gather estimates on
costs, how much sediment would be released with removal and possible
approaches to removal.
The final report,
released in late 2006, estimated it would cost about $88 million to
remove the dams.
Michael Bowen, project
manager with the agency's
Still, Bowen said he was
confident the initial studies are enough to prove that dam removal is
feasible and affordable.
"This is a vast
undertaking," Bowen said. "I think we are at a place where we
can, and should, step forward."
Aftermath of
demolition
A dams-out scenario could
prove fruitful for salmon, but it would leave a noticeable scar on the
rural landscape in
Here, where golden eagles
dive for fish in the reservoirs and river otters swim in from the
Klamath to play in the lake, the landscape would be changed forever.

The California Coastal
Conservancy is focusing now on developing concepts for recreation along
the shores of the river if the dams were to come out, Bowen said.
"If this is changing
from a lake- based recreation area to a river-based recreation area,
what things could we do to enhance that?" said Bowen, citing
possibilities of boat launches and campgrounds.
These ideas will later be

Bowen said he does not
think property values would diminish if homes were to lose the lake.
"You can't just
conclude their economic value is being stripped away because you're
changing whether it's lake-front or river-front," said Bowen,
adding that what could negatively affect home sales now is the current
uncertainty of what will happen to the lakes, given the status of the
settlement proposal.

that their property would lose both monetary and aesthetic value.

If removal is allowed,
the reservoir would first be drained quickly to flush out sediment
captured behind the dam. The dam itself would be cut into pieces and
hauled away to be buried or recycled.
