Last week the Bureau of Reclamation (BOR) announced that it would release additional water from Trinity Reservoir for the lower Klamath River to help protect returning adult fall run Chinook salmon from a disease outbreak and mortality. Supplemental flows from Lewiston Dam would commence on August 21 and extendinto late September. That’s good news for salmon. Read the BOR’s announcement here.
But not so fast. Shortly after the announcement, the San Luis & Delta-Mendota Water Authority along with Westlands Water District filed a lawsuit in federal court to stop the Bureau of Reclamation from releasing Central Valley Project water from the Trinity Division to the Klamath River. In their joint statement, they claim
“The decision by the Bureau of Reclamation to repurpose precious Central Valley Project water resources to augment Klamath flows for non-endangered fish, an action that is of questionable benefit, is both irresponsible and incomprehensible.”
We find their choice of the word ‘repurpose’ ironic given that the original ‘purpose’ of the water is to flow down the river, or be ‘flushed down’ as they put it.
Yes, farmer’s are being impacted by the current drought. But they’re not the only ones. As we and The Nature Conservancy mentioned in our letter to the BOR,
The low flows of 2002 resulted in the largest die off of adult salmon ever recorded in the United States. It is estimated that between 38,000 – 75,000 fish died during this period, mostly fall run Chinook salmon that were just beginning their spawning migration. This preventable event devastated the commercial fishing industry and severely impacted the local Tribes who rely on the fishery as a source of food, as well as centerpiece of their cultural heritage.
The water districts filed a similar lawsuit last year when increased flows were announce and lost. Yesterday, the court denied the Temporary Restraining Order allowing for the increased flows from Trinity Reservoir to the Lower Klamath. You can read their ruling here.

He is co-author of the 2017 book, Floodplains: Processes and Management for Ecosystem Services. His research interests include conservation of aquatic species, habitats, and ecosystems, including salmon; ecology of fishes of the San Francisco Estuary; ecology of California stream fishes; impact of introduced aquatic organisms; and use of floodplains by fish.
Robert Lusardi is the California Trout/UC Davis Wild and Coldwater Fish Researcher focused on establishing the basis for long-term science specific to California Trout’s wild and coldwater fish initiatives. His work bridges the widening gap between academic science and applied conservation policy, ensuring that rapidly developing science informs conservation projects throughout California. Dr. Lusardi resides at the UC Davis Center for Watershed Sciences and works closely with Dr. Peter Moyle on numerous projects to help inform California Trout conservation policy. His recent research interests include Coho salmon on the Shasta River, the ecology of volcanic spring-fed rivers, inland trout conservation and management, and policy implications of trap and haul programs for anadromous fishes in California.
Patrick Samuel is the Conservation Program Coordinator for California Trout, a position he has held for almost two years, where he coordinates special research projects for California Trout, including the State of the Salmonids report. Prior to joining CalTrout, he worked with the Fisheries Leadership & Sustainability Forum, a non-profit that supports the eight federal regional fishery management councils around the country. Patrick got his start in fisheries as an undergraduate intern with NOAA Fisheries Protected Resources Division in Sacramento, and in his first field job as a crew member of the California Department of Fish & Wildlife’s Wild and Heritage Trout Program.
