As the clock ticks down on another summer, many anglers’ thoughts turn to fast-approaching fall fishing patterns.

Lindy guide Jonny Petrowske, who plies Minnesota’s Upper Red Lake, is already looking forward to the walleyes’ annual late-season shoreline migration.

“From September through freeze-up, we catch walleyes in two to seven feet of water,” he said. “Everything from spottail and emerald shiners to baby whitefish crowds into the shallows on Red in the fall. Hungry walleyes come right up there with them.”

Petrowske says the south and eastern shores from Mort’s Dock up and around to Beacon Harbor Resort offer some of the finest fishing.

His tactics of choice include slow-trolling a lip-hooked minnow on a Lindy Spinner Rig behind a 3/8-ounce bottom bouncer, and running the same bait on a Lindy Lil’ Guy behind a 3/8- to ½-ounce Lindy No-Snagg Sinker.

With spinners, he recommends the size 3 Indiana blade option, noting that patterns offering shades of blue and silver — such as Tullibee — are top producers.

“When using a Lil’ Guy, I snip off the rear hook for minnow fishing,” he added, noting that the hybrid rig’s buoyant body allows you to pay out line when a light-biting walleye takes the bait.

With either spinner rigs or Lil’ Guys, Petrowske recommends plenty of letback, to avoid spooking fish in such shallow water. “I tell clients to let out at least a quarter to half of the line on their spinning reel,” he said. “One hundred feet is about right.”

To further reduce the chances of spooking skittish ’eyes, he also uses an electric trolling motor.

Fish size runs the gamut, and is often depth-dependent.

“If you’re seeing a lot of 8- to 10-inchers, try a different depth until you start getting the 15- to 16-inch fish that are perfect Red Lake eaters,” he says.

Toward that end, he also advises varying trolling depths throughout your trip.

“Don’t get hung up on trying to fish a single depth in a straight line,” he offers. “Swing up shallow and out deep to cover all your bases.”
