little leech patterns will do you well this time of year. I use a floating line with a full sink leader and a foot or 2 of tippet. You don't need to fish deep in the water column, the water is cold enough so the fish will be at all depths depending on the conditions. Strip slowly until you get that taptap! You could also use a lighter leader and put an indicator on as well-kind of like chronomid fishing.
I generally stick to brown and black squirl hair leech type patterns. Go smaller rather than bigger. Wooly buggers will do well to.
I LOVE a dark red mohair leech patterns for fall fishing too. It's basically the same thing as a wooly bugger. Totally slayed on that pattern yesterday in my belly boat.
Depending on where you go, you'll mostly encounter cuttys and rainbows.
Deer, Hicks, and Weaver are all decent. Hungry, but moderately sized fish. Average is about 10ish inches?
Good luck with the weather!
