Water release from Trinity Reservoir will begin Saturday, Aug. 23, at 7 a.m.; Public urged to take safety precautions on or near the river while flows are high
REDDING, Calif. – The Bureau of Reclamation will release additional water from Trinity Reservoir to supplement flows in the lower Klamath River to help protect the returning run of adult Chinook salmon. The public is urged to take all necessary precautions on or near the river while flows are high during this period.
“We have determined that unprecedented conditions over the past few weeks in the lower Klamath River require us to take emergency measures to help reduce the potential for a large-scale fish die-off,” said Mid-Pacific Regional Director David Murillo. “This decision was made based on science and after consultation with Tribes, water and power users, federal and state fish regulatory agencies, and others.”
Several recent factors prevalent in the lower Klamath River are the basis for the decision to provide emergency augmentation flows. Reclamation will increase releases from Lewiston Dam beginning at 7 a.m. on Saturday, Aug. 23, from approximately 450 cubic feet per second to approximately 950 cfs to achieve a flow rate of 2,500 cfs in the lower Klamath River.
At 7 a.m. on Monday, Aug. 25, releases from Lewiston Dam will begin increasing to approximately 2,450 cfs to achieve a flow rate of approximately 4,000 cfs in the lower Klamath River. This release from Lewiston Dam will be maintained for approximately 24 hours before returning to approximately 950 cfs and will be regulated at approximately that level as necessary to maintain lower Klamath River flows at 2,500 cfs until approximately Sunday, Sept. 14. River and fishery conditions will be continuously monitored, and those conditions will determine the duration.
“We fully recognize that during this prolonged severe drought, every acre-foot of water is extremely valuable, and we are making every effort to conserve water released for fish health purposes to reduce hardships wherever possible,” added Murillo.
Reclamation will continue to work with NOAA Fisheries and other federal agencies to comply with applicable provisions of the Endangered Species Act and the National Environmental Policy Act.
