- 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, 1,564 spring and summer Chinook salmon, 410 fall Chinook salmon, 430 sockeye salmon, and 1,024 steelhead retained transmitters and were recorded passing John Day Dam via fishways. An additional 19 to 45 spring and summer Chinook salmon, 71 fall Chinook salmon, 38 sockeye salmon, and 17 to 23 steelhead were known to pass the dam, either via the navigation lock, during fishway antenna outages, or with malfunctioning or lost transmitters. We monitored passage and fallbacks at John Day 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.
