A cooperative research program, sponsored by the Office, Chief of Engineers, U.S. Army, was conducted in Elliott Bay near Seattle, Wash., to determine the effects of disposal of dredged material from the Duwamish Waterway in open water. The study involved several agencies, both public and private, investigating various aspects of the disposal operation. The research described in this report was conducted by the National Marine Fisheries Service of the National Oceanic and Atmospheric Administration to determine the effects of dredged material disposal on demersal fish and shellfish at the disposal site. It was concluded that the quantity of dredged material dumped during the study did not have a lasting detrimental effect on the demersal fish and shellfish populations at the disposal site. The investigators recommend a that any future study include a longer period of time for collecting baseline data, b that the characteristics of the reference sites be more comparable to those of the disposal site, and c that the disposal operations be conducted in a manner similar to that which is used in actual practice so the results might have general application.
