Endangered and Threatened Species: Authorizing Release of a Nonessential Experimental Population of Upper Columbia Spring-Run Chinook Salmon in the Okanogan River Basin Under the Endangered Species Act
We, the National Marine Fisheries Service (NMFS), will be considering a proposal to authorize a nonessential experimental population of Upper Columbia (UC) spring-run Chinook salmon (Oncorhynchus tshawytscha) in the Okanogan River and its tributaries in Okanogan County, Washington under the Endangered Species Act (ESA) of 1973, as amended. The geographic boundaries of the experimental population area would likely include the entire Okanogan River subbasin and a portion of the mainstem Columbia River from the confluence of the Columbia and Okanogan Rivers upstream to the base of Chief Joseph Dam. We will consider the best available information to determine if reintroduction of Chinook salmon is biologically feasible and will promote the conservation of the UC spring-run Chinook salmon Evolutionarily Significant Unit (ESU). This advance notice of proposed rulemaking (ANPR) identifies policy and technical issues for consideration and evaluation, and solicits comments regarding them.
