Fishing the West Canada Lakes

I am planning a trip into the West Canada Lakes in August (French Louie loop). I want to do some (Tenkara) fly fishing while there and I am considering bringing in my pack raft. I don't know what to expect in terms of fishing and would be interested in your thoughts, advice and tips on this and whether having the pack raft would be advantageous. I will have 6-8 days if I want them. Thanks!
