Stay in the middle of the channel in most places and you'll be fine. What are you going to be fishing for? If you want walleyes, I did real well above Dallas rapids vertical jigging spoons tipped with a piece of worm. If heading towards Dallas be on the look out for a huge rock right in the middle of the channel once you make your right hand turn off the main channel. I stick to the left side when going in, go slow the first time and mark it, then it's nothing to worry about. You'll also want to be careful about half way down the main outlet, there's a bit of a zigzag there. Again, go slow the first time and after that you're golden. I wouldn't waste my time with Canoe channel, but I would head east from the lodge and check out the rapids below the train bridge. Should be able to get into some walleye there as well (Be on the look out for big toothy critters as well)
Be weary of the slot on the French, especially for walleye.
