Excerpt from Passage of Shad at the Bonneville Fishways An evident factor in the decline of the shad was the erection of dams that prevented the fish from ascending streams to reach their natural spawning grounds. Although many of these dams had fish ladders intended to pass fish upstream, the shad generally did not use the ladders. Con sequently, a part of the investigation of the Atlantic-coast shad has been a search for suitable methods of passing shad over obstructions. At the beginning of the study the only fishways we knew of that were utilized by shad were those at Bonneville Dam on the Columbia River in the Pacific Northwest, and a special study was made of the passage of shad by those fishways. This paper is a report of that study. In the study, William H. Rees (now with the State of Washington Department of Fisheries) made the observations at Bonneville Dam and com piled and analyzed part of the data; C. J. Burner and K. G. Weber made many helpful suggestions during the progress of the study; B. A. Fredin and C. H. Walburg helped prepare the statistical analyses; C. E. Atkinson helped plan and carry out the study; and Harlan B. Holmes gave special help in obtaining unpublished records, supplied much of the factual information, and suggested methods of analyzing the data. I am indebted to Ivan Donaldson, resident biologist at Bonneville Dam, for his help and suggestions, and to the Corps of Engineers for the use of unpublished records and for the map and photographs.
