They should hold pretty true, I'd just look at the tides and watch the weather reports for the area if you're aiming for anadromous species such as steelhead or salmon.

I've seen lots of pictures of large Fall Chinook, but I was told by a buddy about 5 years ago all the Chinook that were in that year were little football shaped 15 pounders.
