Book Description
A 15-month study to inventory wildlife resources on 4 proposed terrestrial dredged material disposal sties and 1 intertidal disposal site was initiated. Major emphasis was placed on inventorying birds and mammals to assess the value of these areas to wildlife. Amphibians, reptiles, and plants received less emphasis. Seven species of amphibians and 3 species of reptiles were captured on fill sites 16, 17, and 18 during this study. The spotted frog and Dunn's salamander have been reported only rarely in Grays Harbor County. Most individuals of these two groups of animals would be killed by disposal of dredge materials on these sites. At least 46 species of waterbirds use the main channel and sloughs proximal to the Cosmopolis Reach of the Chehalis River. Mallards and scaup were the most common waterfowl; highest numbers were seen during winter. Areas preferred by waterfowl were river marshes and upper reaches of sloughs. Large numbers (more than 200) of western grebes, gulls and diving waterfowl used the Cosmopolis Reach during all seasons. During dredging, direct impacts to waterfowl and bald eagles would be negligible; most observations were 5 kms or more upstream from proposed dredging activity. Impacts (i.e. decreased hunting success due to suspended particulates) to diving birds would be minimized by dredging between August and October, when numbers of birds are lowest. Dredging during ebb tides would result in sediments disturbed by dredging flowing into the harbor.

Book Description
Four alternative ocean disposal sites with varying distances from the mouth of Grays Harbor, Washington, are discussed as possible sites to dump approximately 3.3 million cubic yards of dredged material resulting from the widening and deepening of Grays Harbor. The remaining 13.4 million cubic yards of dredged material is targeteds for ocean dumping. This report includes the responses of groups and agencies to the questionnaire sent out to collect public opinion data on the proposed ocean dumping project. (Author).
