Restoration of White Salmon River Set: Federal Order to Remove Condit Dam (WA)
The prospect of removing Condit Dam on the White Salmon River moved closer to reality today in a
significant ruling from the Federal Energy Regulatory Commissioning formally ordering the removal
of the dam.
This past October the State of Washington gave their final approval for the project and shortly
thereafter the local county governments settled their outstanding issues with dam owner
PacifiCorp. With today's ruling federal regulators have now formally cleared the path for removal
in October of 2011.
In today's project surrender order Commissioners of the Federal Energy Regulatory Commission
stated, "We conclude, based on the record of this case, that the benefits of dam removal to
anadromous fish, wildlife, and whitewater recreation outweigh the costs associated with the loss
of Condit dam and Northwestern Lake." They further stated that these benefits of removal
"cannot be achieved if the dam is left in place."
Many partners from the river conservation, recreation, and fishing communities have worked on
this project and while some steps remain we are excited to have a real schedule for this
project.
"The rivers of the Columbia River Gorge represent some of the nation's most outstanding
whitewater resources, and at the heart of the Gorge the White Salmon River is known worldwide for
its scenic beauty and high quality whitewater", noted Thomas O'Keefe, American Whitewater's
Pacific Northwest Stewardship Director. "Condit Dam was originally constructed a century ago
for hydropower and at the time met a local community need. Now we recognize other values of the
river and while the dam itself is big, the hydropower project is relatively small especially in
light of its major environmental impacts--its time has passed." In 1999 American Whitewater
joined a diverse group of stakeholders, including dam owner PacifiCorp, who all agreed that dam
removal was the best alternative among those considered for the future of the hydroelectric
project.
"While we did not envision a decade-long review of this agreement at the time, the final
outstanding issues are quickly being resolved," said O'Keefe. "With final approval by
the State Department of Ecology this past fall, a formal settlement with the local county
governments last month that addressed their outstanding issues, and final approval from federal
regulators, we are ready to remove the dam."
The 125 foot dam, will be one of the largest dams ever removed and we anticipate a high profile
event in a dramatic draining of the reservoir. The proposed method for dam removal involves
drilling and blasting a 12-foot by 18-foot drain tunnel in the base of the dam to within a few
feet of the dam's face. During the month of October 2011 the remainder of the tunnel will be
blasted to drain the reservoir and flush impounded sediments out of the reservoir as rapidly as
possible. Following the final tunnel blast, the drain tunnel will discharge at a rate of 10,000
cubic feet-per-second--approximately 25 percent of the estimated peak discharge during the
February 1996 flood event on the White Salmon River. This will drain the reservoir in
approximately six hours. Rapid draining of the reservoir is expected to mobilize much of the
estimated 2.3-million cubic yards of sediment that have accumulated behind the dam since its
construction.
There may be some disruption to recreational access on the stretch of the river that ends at the
park on Northwestern Reservoir. This summer PacifiCorp will be rebuilding the bridge at the head
of the reservoir that needs new supports designed for a river environment. PacifiCorp has
committed to working with the whitewater community in an attempt to identify alternate access
sites upstream of the bridge. Once the reservoir is drained they will work to provide a temporary
boat access at the park that extends to the new waterline. American Whitewater will continue
working with PacifiCorp throughout the process.
Restoration of this river is important for both fish and recreational users. Fed by the springs
draining off Mt. Adams, the river is one of the more important tributaries in this reach of the
Columbia River with consistent summer flows of cool water that provide year around boating for
paddlers and critical cold water habitat for fish trying to escape the heat of summer.
