The Tyee Test Fishery began on May 25th this year and is scheduled to continue until ~September 24th.
Skeena (Tyee Test Fishery) summer steelhead estimate summary info: The Tyee steelhead index to August 19th is 157 - well above average for this date (average: 77; worst year: 23 ('57); best year: 207 ('98), if direct comparisons between years were valid (please see caveat, below).
