The following is a news release regarding the protection of juvenile coho salmon on the Klamath River.
SAN FRANCISCO—Today, a U.S. District Court judge ordered federal agencies to immediately take steps to protect juvenile coho salmon after several years of deadly disease outbreaks in the Klamath River.
Klamath River coho salmon are listed as threatened species under the federal Endangered Species Act. These fish are central to the cultural identity and survival of tribal nations along the river, and commercial fishermen rely on California’s second largest salmon producer for their livelihoods.
The Yurok Tribe, Pacific Coast Federation of Fishermen’s Associations, Institute for Fisheries Resources, Klamath Riverkeeper, and the Hoopa Valley Tribe sought a court order to compel federal agencies to manage river flows to protect juvenile coho salmon. Mismanagement of Klamath River flows below four major dams led to an outbreak of disease from a parasite called C. shasta in more than 90 percent of sampled juvenile salmon in 2015 and nearly that many in 2014. During the course of the case, the Bureau of Reclamation and National Marine Fisheries Service acknowledged their obligation to engage in consultation to develop mitigation measures to prevent future disease outbreaks.
In today’s order, U.S. District Judge William H. Orrick found that the Bureau’s operation of the Klamath Project is causing irreparable harm to the salmon and the Yurok Tribe and fishing families and that water levels appear favorable this year for the mitigation flows needed to reduce that harm. He found that, based on the best available science, "Plaintiffs have demonstrated that flushing flows and emergency dilution flows would reduce C. shasta rates among Coho salmon. There is no meaningful dispute among the parties on this point." He rejected pleas for delay to consider more evidence, stating "Where plaintiffs have shown a threat of imminent harm to Coho salmon, waiting for perfect science is not appropriate."
To protect the young salmon during the renewed biological review, Judge Orrick ordered the National Marine Fisheries Service and the U.S. Bureau of Reclamation to:
- Release sufficient water in the next few months to flush out organisms from the Klamath river.
