Yeah, hit the high lakes out there. Lots of good lakes for various varieties of trout. You can keep em too. Eastern Brook there is no limit, the rest (except Bull and Dolly Varden) the limit is 5 total. Eastern Brook don't count toward the limit. Forget the streams and go with the lakes if you want trout to eat. There are places you can keep trout on the Lewis system, but navigating that probably isn't worth it.
