Thanks......I'm not aware that "jacks are a targeted fish in WB", yes I'm sure there are many caught while fishing for adults.

Chehalis Basin has a "very active jack fishery".... Most of that fishery is between Montesano and Fuller Bridge.....the active fishing area have "tide affected, and regular water flows that have been heavily fished for the 50 years I've lived here.

I'm sure that any areas that have hatchery Coho releases, will have "Coho jacks", just that available access is reduced on many rivers, unless you have a boat.

Again, thanks for your input.........
