| Abstract: | We outfitted 853 spring and summer Chinook salmon Onchorhynchus tshawytscha with radio transmitters at Bonneville Dam in 1996, 1,016 in 1997, and 957 in 1998. We outfitted 577 sockeye salmon O. nerka in 1997, 770 steelhead O. mykiss in 1996, 975 steelhead in 1997, and 1,032 fall Chinook salmon in 1998. Of these, 1,894 spring and summer Chinook salmon, 616 fall Chinook salmon, 485 sockeye salmon, and 1,219 steelhead retained transmitters and were recorded passing The Dalles Dam via fishways. An additional 1% to 3% were known to pass the dam, either via the navigation lock or during antenna outages. We monitored passage and fallbacks at The Dalles Dam using antennas/receivers in the tailrace and fishways in all years and supplemented that data with recapture records, telemetry records from receivers at upriver dams and the mouths of tributaries, and locations of fish by mobile trackers. |
