Reclamation to Increase Releases from Lewiston Dam to the Trinity River for
Tribal Ceremony and Lower Klamath Flow Augmentation

WEAVERVILLE, Calif. – On Sunday, August 25, 2013, at approximately 8 a.m.,
the Bureau of Reclamation will begin to increase releases from Lewiston Dam
to the Trinity River in support of the Hoopa Valley Tribe's bi-annual Boat
Dance Ceremony. The increased flows in the Trinity River will also meet
downstream needs and will be adjusted at rates that protect the public and
fish and wildlife.

The increased releases will raise flows gradually from the summer base flow
of 450 cubic feet per second to a peak of 2,650 cubic feet per second by
midnight Sunday.
Following the close of the ceremony, on Tuesday, August 27, 2013, at
approximately midnight, the flows will begin to be gradually reduced to a
rate of approximately 850 cubic feet per second. To protect the near-record
Chinook salmon return in the Klamath River, releases from Lewiston Dam will
then vary from about 850 to 900 cubic feet per second until approximately
September 19, 2013, when flows will gradually be reduced back to 450 cubic
feet per second. As always, the public is urged to exercise caution when
recreating in or around the Trinity River.
