{"abstract":"We, the National Marine Fisheries Service (NMFS), are issuing a final rule to authorize the continued release of Middle Columbia River (MCR) steelhead (Oncorhynchus mykiss) that are currently being reintroduced as part of an ongoing reintroduction effort into the upper Deschutes River basin in portions of Jefferson, Crook, and Deschutes Counties, Oregon, and designate them as a nonessential experimental population (NEP) under the Endangered Species Act (ESA) of 1973. The geographic boundaries of the NEP extend upstream from Round Butte Dam on the Deschutes River (about river mile (RM) 110, river kilometer (rkm) 177) and all accessible reaches of the Deschutes River and its tributary Whychus Creek; on the Crooked River from its confluence with the Deschutes River upstream to Bowman Dam (RM 70, rkm 113) and all accessible tributaries between these points; and on the Metolius River from its confluence with the Deschutes River upstream to all accessible tributaries between these points. This NEP designation will have an expiration date 12 years from the effective date of this final rule. We anticipate providing a notice in the Federal Register about 1 year before the NEP designation is set to expire to provide adequate notice to the public.","action":"Final rule.","agencies":[{"raw_name":"DEPARTMENT OF COMMERCE","name":"Commerce Department","id":54,"url":"https://www.federalregister.gov/agencies/commerce-department","json_url":"https://www.federalregister.gov/api/v1/agencies/54","parent_id":null,"slug":"commerce-department"},{"raw_name":"National Oceanic and Atmospheric Administration","name":"National Oceanic and Atmospheric Administration","id":361,"url":"https://www.federalregister.gov/agencies/national-oceanic-and-atmospheric-administration","json_url":"https://www.federalregister.gov/api/v1/agencies/361","parent_id":54,"slug":"national-oceanic-and-atmospheric-administration"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2013/01/15/2013-00700.html","cfr_references":[{"chapter":null,"citation_url":null,"part":223,"title":50}],"citation":"78 FR 2893","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"The effective date of this rule is January 15, 2013.","disposition_notes":null,"docket_ids":["Docket No. 110427267-2708-02"],"dockets":[],"document_number":"2013-00700","effective_on":"2013-01-15","end_page":2907,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2013/01/15/2013-00700.xml","html_url":"https://www.federalregister.gov/documents/2013/01/15/2013-00700/endangered-and-threatened-species-designation-of-a-nonessential-experimental-population-for-middle","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2013-00700?publication_date=2013-01-15","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2013-01-15/2013-00700/mods.xml","not_received_for_publication":null,"page_length":15,"page_views":{"count":616,"last_updated":"2026-09-22 04:15:07 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2013-01-15/pdf/2013-00700.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2013-00700.pdf?1358171463","publication_date":"2013-01-15","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2013/01/15/2013-00700.txt","regulation_id_number_info":{"0648-BB04":{"issue":"201210","html_url":"https://www.federalregister.gov/regulations/0648-BB04/endangered-and-threatened-species-designation-of-a-nonessential-experimental-population-for-middle-c","title":"Endangered and Threatened Species: Designation of a Nonessential Experimental Population for Middle Columbia River Steelhead above the Pelton Round Butte Hydroelectric Project in the Deschutes River","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=201210&RIN=0648-BB04&operation=OPERATION_EXPORT_XML","priority_category":"Substantive, Nonsignificant"}},"regulation_id_numbers":["0648-BB04"],"regulations_dot_gov_info":{"supporting_documents":[],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/0648-BB04/endangered-and-threatened-species-designation-of-a-nonessential-experimental-population-for-middle-c","title":"Endangered and Threatened Species: Designation of a Nonessential Experimental Population for Middle Columbia River Steelhead above the Pelton Round Butte Hydroelectric Project in the Deschutes River"},"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=NOAA-NMFS-2011-0132","supporting_documents_count":0,"docket_id":"NOAA-NMFS-2011-0132","regulation_id_number":"0648-BB04","title":"Endangered and Threatened Species: Designation of a Nonessential Experimental Population for Middle Columbia River Steelhead Above the Pelton Round Butte Hydroelectric Project in the Deschutes River Basin, Oregon","checked_regulationsdotgov_at":"2013-02-19T17:36:12Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":2893,"subtype":null,"title":"Endangered and Threatened Species: Designation of a Nonessential Experimental Population for Middle Columbia River Steelhead above the Pelton Round Butte Hydroelectric Project in the Deschutes River Basin, OR","toc_doc":"Designation of Nonessential Experimental Population for Middle Columbia River Steelhead, etc., in the Deschutes River Basin, OR","toc_subject":"Endangered and Threatened Species:","topics":["Endangered and threatened species","Exports","Imports"],"type":"Rule","volume":78}
