This publication is a compilation of three separate reports which collectively evaluate and describe the effectiveness and aquatic impact of propeller wash agitation dredging at Chinook Channel, Washington, during March and April 1976. Part 2 describes the dredging operation, hydrographic surveys, tides and currents, sediment sampling, and the advantages and disadvantages found with this method of dredging.
Section I, by the Hammond Field Facility of the National Marine Fisheries Service, documents the changes in epibenthic estuarine fish and invertebrates from the propeller agitation dredging.
Section II, by the Prescott Field Facility of the National Marine Fisheries Service, describes the effect of agitation dredging on benthic communities, water quality, and turbidity at Chinook Channel.
