I know most reports from Winnibigosh have been of a tough bite, so I hears some good news. My Dad and I just got from 2 days of prefishing and 2 days of tournament fishing in the MTT event. While prefishing we tried everything from shallow weeds in 8 feet out to open water trolling in 40 feet. We primarily trolled to cover water prefishing and caught one here and there with only 2 keepers over 2 days. On the tournament days we slowed down and worked the edge of a sand flat in 13-15 feet pulling spinners. Both days we caught around 15 fish and over the 2 days we had 18 keeper-sized fish. There were other boats in this area and they were getting keeper fish too. Each day we did troll on another hump for awhile and picked up a couple keepers and fish up to 20 inches. There were about 20 limits each day, so overall the bite was much better than 2 weeks ago.
I should point out that if you are just looking for action, trolling along weed edges in 12-15 feet will keep you busy with Perch, Perch, Northerns, and Walleyes in that order.
