This report is the second in a series detailing the procedures used and the results obtained from studies designed to determine the impacts of erosion control structures on fish habitat at Willapa Bay, Washington. The erosion control structure, consisting of a 1600-ft rock groin and an attached 930-ft underwater dike was placed on Washaway Beach in 1998 to protect State Route (SR) 105 from erosion. The objectives of the study are to develop an understanding about whether groin-type structures on the outer coast can alter migratory movement or predation pressure on juvenile and adult salmon. Field surveys in this report were conducted from October 14-21, 2001, and consisted of gillnetting, passive drifter surveys, diver surveys, interviews with fishers and Washington Department of Fish and Wildlife (WDFW) personnel, bird and mammal surveys, and split beam hydroacoustic surveys. Field sampling activities were begun on October 14 and were suspended during the commercial gillnet season from October 16-18. Interviews with fishers and WDFW were conducted during that period, and field sampling recommenced on October 19. The hydroacoustic surveys were conducted from October 19-21. The migration pattern of fish, presumed to be salmon, was documented relative to the tidal phase. Fish were observed tomore » congregate in the deeper portion of the channel during the end of the ebb tide. The fishermen set their nets and rid the tide upstream as they catch fish. Many fewer fish were observed in the channel at the high tide stand.« less
