The last two walleye openers were in Gowganda and Shining Tree areas. In the first trip, the fish were still hanging around their spawning grounds at the river mouth and so I could at least locate them. The biggest problem for me is locating them in a lake. I suppose trolling is the way to go to find them in an unfamilar lake, but even in a lake that's not that big, say 5 miles long and 2 miles wide, it's rather daunting to cover so much water--and the fish keep moving all the time!
So, how do you guys go about locating walleye in an unfamiliar lake? Do you look for particular structures/features and hit them hard, or do you more or less troll the whole lake systematically grid by grid? When trolling, do you always keep your lure close to the bottom or run them at different depths?
