Released On: August 07, 2013
REDDING, Calif. – The Bureau of Reclamation will release additional water from Trinity Reservoir to supplement flows in the Lower Klamath River in 2013 to help protect an expected large returning run of adult Chinook salmon from a disease outbreak and mortality. The target date for augmented flows in the Lower Klamath River is August 15. Because of the two day travel time between Lewiston Dam and the Lower Klamath, the releases from Lewiston Dam will begin in the early morning hours of August 13 and end in the last week of September.
Flows in the Lower Klamath River will be targeted at 2,800 cubic feet per second during this period and Lewiston Dam releases will be adjusted accordingly. Current river flow forecasts indicate that Lewiston Dam releases will increase from the current rate of 450 cubic feet per second on August 13 and will vary between about 1,000 and 1,200 cubic feet per second, prior to dropping to 450 cubic feet per second in late September. Between August 26 and August 27, a pulse flow release from Lewiston Dam could be as high as 2,600 cubic feet per second.
The rate of increasing releases could be as high as 250 cubic feet per second every two hours, and the rate of flow reductions could be as high as 100 cubic feet per second every four hours. The public is urged to take all necessary precautions on or near the river while flows are high.
