On April 7, 2000, the National Marine Fisheries Service (NMFS) received a request from the U.S. Army Corps of Engineers, Portland District (COE) for Endangered Species Act (ESA) section 7 formal consultation for programmatic coverage for a proposed Regional General Permit (RGP) for certain stream restoration activities (habitat restoration using large wood or boulders throughout the State of Oregon) requiring COE approval. The Biological Assessment (BA) provided with the request determined that the proposed activities covered under the RGP would be likely to adversely affect anadromous fish species listed under the ESA (Table 1). Species considered in this Biological Opinion (Opinion) are: Snake River sockeye salmon (Oncorhynchus nerka); Snake River spring /summer chinook salmon (O. tshawytscha); Snake River fall chinook salmon (O. tshawytscha); Lower Columbia River steelhead (O. mykiss); Upper Columbia River steelhead (O. mykiss); Snake River steelhead (O. mykiss); Upper Willamette River steelhead (O. mykiss); Middle Columbia River steelhead (O. mykiss); Columbia River chum salmon (O. keta); Lower Columbia River chinook salmon (O. tshawytscha); Upper Willamette River chinook salmon (O. tshawytscha); Upper Columbia River spring run chinook salmon (O. tshawytscha); S. Oregon/N. California Coast coho salmon (O. kisutch); and Oregon Coast coho salmon (O. kisutch). On April 18, 2000, NMFS received a letter from COE providing additional information on proposed criteria to be included in the RGP. On May 12, 2000, NMFS received an e-mail with further proposed criteria to be included in the RGP.
