MasterAngler- Despite being this far north I find most big walleye > 25in. in 15 to 25 ft of water on mid lake reefs. We have a  particularly good producing spot that has a 15 - 20 ft flat about 100 yds long in a narrows. Fish are a bit scattered but when they are there ...they are there. Windswept points and along deep weed edges are producers too. I have also tried surface troling when ciscoes rise on lake surface after sunset but have had only modest success on large size, but numbers have been good with this method.

I normally fish with Cabela glow spiner floating worm harnesses with 1/2 a nightcrawler with a 1/2 -3/4 oz slip sinker. I also use Northland Whistler propeller jigs  or Capn Red Beard jigs with a twister tail and bit of a worm or Gulp leech. I agree with you... since the live bait ban in Quetico my walleye numbers and size have diminished by 1/3. It is still very good but I know many agree with me ... including Stu Ostoff, publisher of BW Magazine and guide. Gulp is good but not as good as live bait.  Last year our group only caught  13 walleyes over 25 inches. Two years ago when there was a steady barometer all week and a descent walleye chop we hit a home run that we may never equal again: 55 walleye over 25 in. with several over 30 in. Remember, we have been fishing this lake for many years and know it well.

I really like the dark stained water up there and it produces well during daylight hours.
