The National Marine Fisheries Service (NMFS) is issuing a final determination that the Ozette Lake sockeye salmon (Oncorhynchus nerka) Evolutionarily Significant Unit (ESU), located on Washington's Olympic Peninsula, is a threatened species under the Endangered Species Act (ESA) of 1973, as amended. NMFS also reviewed the status of Baker River sockeye salmon, previously designated as a candidate species. Based on that review, NMFS has determined that Baker River sockeye salmon do not warrant listing under the ESA, nor candidate status at this time. NMFS previously determined that the Okanogan River, Lake Wenatchee, Quinault Lake, and Lake Pleasant (all located in Washington) sockeye salmon ESUs did not warrant listing. However, based on new information, NMFS remains concerned about the status of the Okanogan River and Lake Wenatchee ESUs, and will closely monitor their status. At this time, NMFS is listing all naturally spawned populations of Ozette Lake sockeye salmon belonging to the species' anadromous life form. NMFS has examined the relationship between hatchery and natural populations of sockeye salmon in this ESU and determined that none of the hatchery populations are currently essential for recovery and, therefore, the hatchery populations (and their progeny) are not listed. NMFS will issue any protective regulations deemed necessary under section 4(d) of the ESA for the listed ESU in a separate rulemaking. Even though NMFS does not now issue protective regulations for this ESU, Federal agencies are required under section 7 to consult with NMFS if any activity they authorize, fund, or carry out may affect listed sockeye salmon.
