We had one awesome day last year in November, and have had limited success on a few other outings. We've never been able to be consistent on the damn things and have invested many hours for relatively few fish.
What success we have had has been on flashers and either pink & blue squirts or UV hootchies trolled between about 20 and 90 feet. Our best success came in mid channel right off Pat Bay fishing around jumpers. I will always remember the one day when we simply couldn't keep them off, but there were at least 10 other days that were lessons in frustration - fish all around you (sometimes literally hitting the boat!) and not a sniff for hours. We usually managed one or two, (for about 4 - 6 hours fishing)but given the huge schools of fish, I'd suggest that they typically don't bite well in this area. Not like north of the Narrows in the Campbell River area, anyway.
I moved to Victoria this summer so its unlikely I'll be chasing Chums this Autumn (the odds are just too long, and Juan De Fuca still has many secrets left for me to discover!)but best of luck to those of you who try. And hey, it sure beats sitiing on the couch, right?
Tight lines...
