River flows increase starting Tuesday
Release of water from Trinity Lake to the Trinity River will increase starting early Tuesday, Aug. 13, to help protect an expected large returning run of Chinook salmon from disease, the federal Bureau of Reclamation announced.
Reclamation urges the public to take precautions on or near the river while flows are high.
The Trinity flows will be adjusted in order to reach flows of 2,800 cubic feet per second in the lower Klamath River from mid-August through the last week of September. Current flow forecasts indicate that Lewiston Dam releases will increase from the current rate of 450 cfs on the 13th and will vary between about 1,000 and 1,200 cfs, prior to dropping to 450 cfs again in late September. Between Aug. 26 and 27, a pulse flow release from Lewiston Dam could be as high as 2,600 cfs.
The rate of increasing releases could be as high as 250 cfs every two hours, and the rate of flow reductions could be as high as 100 cfs every four hours.
An Environmental Assessment and Finding of No Significant Impact were prepared for the higher releases under the National Environmental Policy Act and are available online at http://www.usbr.gov/mp/nepa/nepa_projdetails.cfm?Project_ID=14366.
