Water samples from Copco and Iron Gate Reservoirs
contain extremely high levels of the toxic blue-green algae
Microcystis aeruginosa for the third consecutive year since monitoring
began in 2005. Microcystis aeruginosa produces the toxin microcystin
which is known to cause liver failure and promote tumor growth.
Microcystin exposure can lead to organ failure and death.

The reservoirs are located on the Klamath River near the Oregon border
between Ashland, OR and Yreka, CA. The dams are owned by PacifiCorp, a
subsidiary of Buffett’s Mid American Energy Holdings Company.
“Although Siskiyou County officials have the
responsibility to inform and protect the public from exposure, it’s
not their fault these blooms are occurring. Warren Buffett’s dams
are to blame,” according Leaf Hillman, Vice Chair of the Karuk
Tribe.
Recently officials from the California Water Quality
Control Board and the Office of Environmental Health and Hazard
Assessment formed a Blue Green Algae (BGA) Work Group. The BGA Work
Group recently published a document to provide guidance to local
health officials dealing with toxic algae blooms. Samples taken
recently from Klamath reservoirs contained cell counts approximately
100 times greater than the threshold at which the BGA Work Group’s
document recommends
posting alerts to the public.
According to the BGA Work Group Document, when the
probability of adverse health affects are high, typical actions by
local authorities includes “immediate action to control contact with
scums including prohibition of swimming and other water contact
activities.”
The blooms occur in the summer as the shallow,
nutrient rich water trapped behind the dams heats up and thus provides
an optimal environment for the algae to bloom. For years, down river
Tribes, fishermen, and conservation groups have called for the removal
of the dams to restore runs of salmon that are in dramatic decline and
alleviate the toxic blooms.
In May Klamath River Keeper and other affected
community members filed a public nuisance claim against PacifiCorp
over the role the dams play in creating algae blooms and creating
conditions lethal to salmon. Said Hillman, “PacifiCorp is destroying
the most vital natural resource river and coastline communities have
while poisoning us at the same time.” Lawyers for the plaintiffs
include Robert Kennedy, Jr. of the National Water Keeper Alliance and
Joseph Cotchett. Tribal and state governments are not plaintiffs in
the suit.
Last May, Hillman and other Tribal leaders joined
with conservation groups and fishermen to take their grievances
straight to Buffett at Warranpalooza, the annual shareholders’
meeting of Buffett’s investment firm Berkshire Hathaway. Buffett
declined to address the groups’ appeal to remove the Klamath dams.
“In the end, PacifiCorp’s investors and
ratepayers will hold its management accountable. Not only is removing
these toxic waste factories the moral thing to do, it’s the
economically sound decision as well,” stated Hillman.
Hillman refers to the economic analysis performed by
the California
Energy Commission which concludes
that PacifiCorp would save over $100 million by removing the dams
instead of meeting the terms of a new operational license.
Currently over two dozen Klamath Basin stakeholders
are seeking to negotiate an agreement that would remove the dams as
well as address issues of in stream flows and power needs of farmers.
“Everyone in the Klamath Basin is working on
solutions to these problems. Its time for PacifiCorp to get real about
removing these dams and stop exploiting Klamath communities and their
own ratepayers,” concluded Hillman.
For more information, see the California
Coastal Commission sediment study
that concludes that dams can be removed safely.
Craig Tucker received his B.S. in biochemistry
from Clemson University in 1993 and a Ph.D. in biochemistry from
Vanderbilt University in 1999. He was the Outreach Director at Friends
of the River, developing grassroots campaigns on a variety of
California water issues. Each campaign was based on the connection
between sustainable environmental policy and social justice. Currently
Craig is the Campaign Coordinator for the Karuk Tribe's 'Bring the
Salmon Home' campaign. The goal: removal of four dams on the Klamath
River which would represent the largest dam removal project in
history. Tucker and the Karuk Tribe have produced a film, "Solving
the Klamath Crisis; Keeping Farms and Fish Alive".
