The Bureau of Reclamation will begin to increase releases from Lewiston Dam
to the Trinity River beginning Friday, Aug. 22 in support of the Hoopa
Valley Tribe bi-annual Boat Dance Ceremony held in Hoopa, California.

Beginning Aug. 22, Lewiston Dam releases are scheduled to gradually
increase from the summer base flow of 450 cubic feet per second and are
expected to reach a peak release of 2,300 cfs on Aug. 25 before returning
to summer base flows on Aug. 30.

River recreators can expect a higher volume of water and increased
turbidity in the Trinity River during the ceremonial flow. As always, the
public is urged to exercise caution when recreating in or around the
Trinity River.

The hourly change order is included in the forwarded message below.
