Reclamation to Release Additional Water from Trinity Reservoir to Supplement Flows in the Lower Klamath River

REDDING, Calif. – The Bureau of Reclamation will provide a one-day pulse flow from Lewiston Dam to help protect returning adult fall-run Chinook salmon in the lower Klamath River as identified in the Final Environmental Assessment and Finding of No Significant Impact for this project which are available at http://www.usbr.gov/mp/nepa/nepa_projdetails.cfm?Project_ID=22309.

In addition to the current supplemental flows being released out of Lewiston Dam to protect salmon, the one-day pulse flow is scheduled to commence on Tuesday evening, September 8, as a secondary preventative measure. The pulse flow will be implemented because of the continued presence of low-level infections of adult salmon by Ich, the disease thought primarily responsible for the fish die-off in 2002.

The flow from Lewiston Dam will increase from the current rate of 1,100 cubic feet per second and would peak at approximately 3,300 cfs for one day; it would then begin ramping down until reaching approximately 1,100 cfs the following day.

The public is urged to take all necessary precautions on or near the river while flows are high.
