Existing island and shoreline dredged-material disposal sites are nearly filled to capacity, and options for new disposal sites for such large volumes of dredged material are extremely limited. One potential disposal site is the area just north of Rice Island, an island created with dredged material. Proposals for expanding Rice Island with dredged material include creating a 10,000-ft (3,048-m) by 500

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 distribut

Emmett Final Report of Research Financed by U.S. Fish and Wildlife Service Ecological Services Division Portland, Oregon (Contract No. 14-16-009-77-939) and National Oceanic and Atmospheric Administration National Marine Fisheries Service Northwest and Alaska Fisheries Center Coastal Zone and Estuarine Studies Division 2725 Montlake Boulevard East Seattle, Washington 98112 March 1980 ABSTRACT The study provides federal resource agencies base line classification information on an important west coast estuary. Estuarine characterization data were gathered at 3-month intervals from 45 sites in the Columbia River estuary. Replicate samples of benthic invertebrates and sediment structure were taken at each site. The four survey periods, during June, September, and December 1977 and March 1978, resulted in 359 invertebrate samples and 360 sediment samples. Invertebrate samples, taken with a 0.05 m2 Ponar dredge, were preserved, stained, identified to taxonomic group, counted, verified, and weighed. The study involved 212,797 benthic invertebrates--an average of 593 organisms per sample. Embayments on the Oregon side of the estuary had greater numbers of benthic organism whereas weights averaged more on the Washington side. Seasonal shifts in numbers and weights were noted, but changes were not consistent between areas. Important species observed included amphipods: Corophium salmonis, C. brevis, and C. spinicorne; bivalves: Macoma baltbica and Corbicula Manilensis; polychaetes: Neanthes limnicola and Hobsonia florida; copepod: Canuella canadensis; and groups such as nematoda, oligochaeta, nemertea, cumacea, cirripedia, and
