I find if you fish off the main points in the lake in 25-30 feet of water early morning as sun rises or late as the sun sets you can pick up the odd walleye. Usually only half hour of action then no walleye the rest of the day. I'm sure other people have them better figured out than me. My catches are usually incidental cause we usually try for pike out there. Have caught a few nice perch randomly while trying for walleye though. Maybe only caught three but all around 12 inches.
