I too look forward to NZTB's report. According to the Big Salmon web page update on 10 August you can "walk on the backs of the silvers out at swiftsure"! We didn't exactly see that when we were there during that time. Unfortunately, my trips out there are probably done for the year...
Check out the Coho creel counts over at Clallam bay (for some reason they don't include the counts at Big Salmon?).
We are going to try the Posession bar area tomorrow and see what's happening locally.
