I'll start by saying I am just learning to fish, but have not had very good luck.  I have been reading articles in Boundary Waters Journal and Mr. Furtman's book.  I have found that most of the advice is geared toward Spring and Summer fishing.  What are the fish doing this time of year?  Are they coming up from the depths?

Specifically, I am going next week Sept. 23rd to Mountain lake.  Furtman's book says it contains Lake trout and Smallmouth.  What depths should I fish and what should I use for lures?

Should I fish the surface for smallmouth?  The weather outlook looks to be rainy with highs in the 50s.

In general, what do fish do in late September/early October?

Thanks.
