Bureau of Reclamation, Interior.




The Bureau of Reclamation has made available for public review and comment the Draft Environmental Impact Statement (DEIS) for the Long-Term Plan to Protect Adult Salmon in the Lower Klamath River (LTP). The DEIS describes the potential environmental effects of the No-Action and Action Alternatives to augment flows in the Lower Klamath River to reduce the likelihood, and reduce the severity, of any Ich epizootic event that could lead to an associated fish die-off in future years.


Send written comments on the DEIS on or before December 5, 2016. One open house followed by a public hearing will be held on Wednesday, November 9, 2016, in Redding, CA. Doors open at 5:00 p.m.; the open house is scheduled from 5:30 p.m. to 6:30 p.m.; and the public hearing is scheduled from 6:30 p.m. to 8:30 p.m.


Send written comments or requests for copies to Ms. Julia Long, Project Manager, Bureau of Reclamation, Northern California Area Office, 16349 Shasta Dam Blvd., Shasta Lake, CA 96019; or via email to The DEIS is also accessible from the following Web site:​mp/​nepa/​nepa_​projdetails.cfm?​Project_​ID=​22021.

The open house and public hearing will be held at the Holiday Inn, 1900 Hilltop Drive, Redding, CA.

The DEIS documents the potential direct, indirect, and cumulative physical, biological, and socioeconomic environmental effects that may result from implementing flow augmentation actions in the Lower Klamath River.

The DEIS evaluates and discloses any potential environmental impacts associated with implementing the LTP. The purpose of the proposed action is to increase flows in the lower Klamath River to reduce the likelihood, and potentially reduce the severity, of any Ich epizootic event that could lead to an associated fish die-off in future years. The need is based on the past extensive fish die-off that occurred in 2002. Crowded holding conditions for pre-spawn adults, warm water temperatures, and the presence of disease pathogens are the likely major factors contributing to the adult salmon mortalities. The proposed increased flows would be provided primarily from releases of water stored in Trinity Reservoir on the main stem of the Trinity River.

In August and September 2002, an estimated 170,000 fall-run Chinook salmon returned to the Klamath River. During those two months, 33,000 adult Chinook salmon, including 344 Coho salmon which are listed as threatened under the Endangered Species Act, and other salmonids, died prematurely due to infection. Federal, tribal, and state biologists studying the die-off concluded that the pathogens Ich (Ichthyophthirius multifiliis) and Columnaris (Flavobacterium columnare), were the primary causes of death to fish. Contributing factors that lead to the infection were warm water temperatures, low water velocities and volumes, high fish density, and long fish residence times. Flows in the lower Klamath averaged about 2,000 cubic feet per second during September 2002.

Subsequent dry year conditions in 2003, 2004, and 2012 through 2016, prompted Reclamation to arrange for late-summer flow augmentation to reduce the probability of a disease outbreak. In each of these years, 38 thousand acre-feet (TAF) to 64 TAF of supplemental water was released from Trinity Reservoir.

Reclamation recognizes that there is an increasing need to provide augmentation flows in dry years for the foreseeable future to prevent fish mortalities due to Ich and Columnaris. Reclamation is developing a long-term plan to address this need.


The Trinity River Division Authorization Act of August 12, 1955 (Public Law 84-386) and the Trinity River Basin Fish & Wildlife Management Act of 1984 (Act of October 24, 1984, Public Law 98-541), as amended, provides Reclamation the authority to take action to protect fishery resources.
