Dog Lake walleye advice?

Even though we don't leave for 3 1/2 weeks, I'm getting pumped about our trip to Dog Lake in June. We usually get a lot of pike and a few walleyes but would like to turn that around this year. Any suggestions?

We usually fish Dog Lake (near Wawa/Missanabie) and a few of the small lakes in the area. Any basic advice would be appreciated. Also, I can't remember the new slot sizes for Ontario. What are they?

Thanks guys, Trout.
