Anglers have been working hard to catch walleyes this week with some success being found on the humps in 21 to 24 feet, 25- to 31-foot mud, and deep sides of the main lake bars. Putting together a batch of perch involves sorting through small fish with a jig and minnow on the 6- to 12-foot sand. Spoons or crankbaits are producing pike in 8 to 15 feet.
