Description:Potential biological impacts of deepening the Coos Bay, Oregon navigation channel from River Mile (RM) 0 to 15 were discussed at an interagency meeting in March 1989. Participants included the U.S. Army Corps of Engineers (COE) (Division of Ecological Services, Portland District), the U.S. Fish and Wildlife Service, and the National Marine Fisheries Service (NMFS) (Environmental and Technical Services Division of the Northwest Region and Coastal Zone and Estuarine Studies [CZES] Division of the Northwest Fisheries Science Center). One result of this meeting was a general agreement that a preliminary biological survey was required to determine the need for a comprehensive biological assessment of the area impacted by the deepening of the navigation channel. Subsequently, a cooperative agreement was reached between the COE and CZES Division to collect sediment samples at selected intervals over the length of the project and to determine the distribution and abundance of benthic invertebrates. This report summarizes the results of this preliminary investigation.
