coosbo,
Those are good waters for lake trout and I've fished them quite a bit (with the exception of McAlpine, where I've always just "passed through"). My recommendations:
1. Bring a depthfinder & seek a minimum of 40 feet depth (preferably 60).
2. If you are inclined to "jig fish" or if you spot several fish on you screen, the Klos Brothers lures advertised in the BWJ can be productive.
3. Unless I spot a cluster OR I happen to know of a productive "hole", I almost always troll. On Kas & Quetico lakes I've done well with fat-lipped, deep-diving "cisco- like" lures. White "Hellbenders" are my favorite. Flashy six-inch feather-lite Sutton Spoons a close second (trailing behind a clip-on weight). You don't have to get your lure down to 40-60 feet. Trout will come up a LONG ways to attack a flashy lure IF they're feeding.
4. For some reason (probably a change in the forage fish available), I
haven't had as much luck with cisco-like lures on big Pickerel Lake. Rather, I do better with Reef Runners, Bomber lures, & spoons. I've seen some folks put flashy mylar straps on whatever they're using & do well.
5. On Quetico Lake I'll fish straight down the middle of any arm of the lake, as long as I'm in/near 60 feet of water.
6. On Kas, it's the same approach, though I try to fish parallel to the big reefs. Also, I, for one, have had far better luck fishing for LT in the western half of the lake.
7. Like I mentioned earlier, I don't bother fishing McAlpine; probably that's a mistake.
8. On big Pickerel Lake. I like that stretch of water above Wetasi Island & running east from there a couple miles to where it opens up wide & that big white whale rock sits in the middle (nice beach campsites near there, too; just a mile or so north of the dam above Beg, Risk &Bud). Frankly, there's good LT water all the way east on Pickerel out to the Pines. A lot of folks jig their favorite spots on Pickerel, more so than on other lakes in my experience. Pick an island, find 60 feet of water nearby and start
trolling or jigging, whichever is your pleasure.
9. I've had my best luck with lake trout between 10am and 4pm. However, that could well be because I'm almost always fishing for other species earlier & later.
That's what comes to mind at the moment. Feel free to PM me if you'd like me to add a few specifics.
