REDDING, Calif. – The Bureau of Reclamation has released the Draft Environmental Assessment for using Trinity Reservoir-stored water to supplement flows in the lower Klamath River to lessen the likelihood of a fish disease outbreak and a die-off of adult salmon during the late summer of 2015.

Continued dry hydrologic conditions and the recent discovery of the presence of Ich, the fish disease thought primarily responsible for the fish die-off in 2002, has prompted Reclamation to consider supplementing flows to the lower Klamath River in 2015. The Proposed Action includes supplemental flows to prevent a disease outbreak and a contingency volume to be used on an emergency basis to avoid a significant die-off of adult salmon. Real-time environmental and biological monitoring by federal, state and tribal biologists would be used to determine if and when to implement supplemental flows.

The Draft EA was prepared in accordance with the National Environmental Policy Act and is available at If you encounter problems accessing the document online, please call 916-978-5100 or email
