In many Lindy Land fisheries, staying on the bite as summer fades to fall means keeping up with migratory movements of the marble-eyed masses.

While the angles may vary from the Great Lakes to small waters and river systems, Lindy pro and longtime guide Mike Christensen offers one of his pet patterns for catching fish on mighty Mille Lacs Lake and a number of other Midwestern venues.

“When baitfish are abundant near shore, walleyes often make an inward migration toward the shoreline from deeper water offshore,” he said. “So, when your midsummer main-lake hotspots turn cold, it’s worth fishing areas closer to the bank.”

Well-defined deep weedlines and flats where thick stands of early-summer weedgrowth recently died off are potential strike zones. On Mille Lacs, Christensen likes rocky breaklines lying in 15 to 24 feet of water.

A variety of presentations put fish in the livewell, but Christensen says trolling crankbaits is hard to beat for covering water and triggering bites. “Smaller baits like Lindy’s 2 3/8-inch, size 3 River Rocker are standouts,” he reported. “I also like larger lures like the 3½-inch Rally Fish, particularly when larger baitfish are on the menu or I need to trigger reaction strikes.”

Depending on the depth of the target area and the lure’s running depth, he may use leadcore mainline (with a 20-foot superline leader) to reach the fish with shallow-diving lures.

“Rally Fish dive 26 feet on the troll, so they’re perfect for covering the base of a break or top of a deep flat all by themselves,” he said, noting that perch color patterns are deadly weapons right now on many lakes.

“Splashes of orange or pink can help the bait stand out from schools of baitfish, so don’t be afraid to experiment,” he said, adding yet another tantalizing clue to unlocking the mystery of late-summer walleyes.
