I have been to the boundry waters several times and done well for walleye. Lood for any moving water, especially where one lake or creel falls into another lake or where a flowing lake narrows and creates a channel of miving water. I ussually fish big curlytail grubs bounced of the bottom. Also look for steep bluffs and fish the dropoffs or look for mid lake reefs or humps and fish the edge of them, where rock turns to mud bottom. You can catch them in the evenings shallow on rogues or other stick baits on chunk rock banks or in areas of large boulders.
We would always go the last week may or first week in june. We would absolutely hammer huge lake trout & monster pike. 20"-27"spawning smallmouth were not uncommon and we would catch big numbers of average size walleye. I have not been able to go for the last two years. I'm jealous. Good luck. Give us areport when you return.
