This project, in part, involved determination of the effects, if any, 

 of dredging of the Intracoastal Waterway in Georgia on estuarine organisms. 

 Emphasis was placed on fishes and macroinvertebrates as obtained through otter 

 trawling. The data were partially analyzed by several computer programs; length- 

 weight relationships and condition factors were included. The current report pre- 

 sents length-weight data for several fishes and invertebrates and also the condition 

 factors for those fish for which length-weight relationships were obtained.

 and Benthic Macroinvertebrates," Technical Report Series No. 72-4, Georgia

 July 1972. 



Collections of fishes and invertebrates made by otter trawl from November 

 1970 through December 1971 from stations within the Georgia coastal estuarine 

 system were evaluated in terms of effects of hydraulic dredging activities 

 associated with the Intracoastal Waterway on the biota collected. The patterns 

 of seasonal occurrence and dominance of specific organisms appeared to be con- 

 sistent regardless of whether or not dredging had occurred in the area sampled. 

 Variability among the stations seemed to be associated with natural hydrographic 

 and physiographic characteristics, as well as sampling variability. Some changes 

 in the population structure or standing crop may have been associated with the 

 dredging, but these effects were transient, lasting no longer than 1 or 2 

 months following dredging.

 Studied," World Dredging and Marine Construction, Vol. 9, No. 9, July 

 1973, pp. 34-37. 



This study focused on the immediate and long-term effects of hydraulic 

 dredging on two estuarine communities of animals. The evidence obtained from 

 the studies indicates no gross or long-term effects of the Atlantic Intracoastal 

 Waterway (AIWW) dredging on fishes and macroinvertebrates. Maintenance dredging 

 of the AIWW is not comparable with dredging of polluted and possibly toxic 

 sediments.

 Marinas, Breakwaters, Bulkheads and Land Fills in the Columbia River 

 and Coastal Bays," Washington Department of Fisheries, Olympia, Wash., 

 unpublished, 1974. 



This paper describes possible adverse effects on water quality and fish 

 and shellfish habitats as a result of marinas, breakwaters, bulkheads, and 

 landfills at a number of locations on the lower Columbia River and several 

 Washington coastal bays. The main concern was water quality deterioration and 

 predator buildup as factors that affect juvenile migrating salmon. Recommenda- 

 tions for design criteria of future structures are made that will alleviate 

 these adverse effects.
