PSU-

I'm not a Quetico paddler.  I just paddle the BW.  that being said there are some good resources out there and I'm sure you'll get some advice from some Quetico padlers.  That being said there is a book out that might be a good place to start.

The book is Furtmans Boudary Waters fishing guide (not sure the actual name, I'll have to get back to you on that).  the book covers Quetico Lakes as well.  It does a fairly good job at telling oyu what species to suppect in the lakes you plan to travel and will give some basic fishing tips on how to get them.

Have a great trip!
