Oregon kokanee in the fall

[sawdustsavage]

I just got back from Alaska and I was wondering how late in the fall fishing stays good in various lakes. I assume the higher the lake the earlier the spawn.
Since this is my first year I would appreciate any info that you could give me. I need to try out a new smoker I bought in Joseph.101duh I geuss I was a little optomistic. No matter it was a great trip. I would like to try out witting them a few more times. Maybe SOME of my electronics will work this time.
Thanks John
