Portly yellow perch are popular targets of winter warriors across Lindy Land, but finding herds of jumbos roaming deep offshore basins can be challenging as winter wears on.

One trick to finding fish fast is focusing on areas where a hard bottom meets softer substrate. Such transition zones can be underwater buffets for hungry perch, as harder bottoms hold baitfish while the goo nurtures insect life.

Depths vary from one lake to another, but 25 to 35 feet is commonly productive in many Midwestern perch fisheries. And even in shallow, bathtub-like lakes, bottom transitions may hold the biggest perch in the lake.

To check a promising area for perch, punch a line of pilot holes over the transition and use flashy, noisy jigging lures to get the fish’s attention. If there are perch in the area, you’ll see them move in on your sonar.

Top picks include Lindy’s Perch Talker, Frostee Spoon and Rattl’n Flyer Spoon. Choose tippings based on predominant forage. Use a minnow head if you’re on the hard bottom side of the transition, where baitfish are on the menu; waxworms excel on the soft side, where insects are the main course.

Use aggressive jig strokes to call the fish in, then tone down your presentation once perch appear on sonar.

One final tip: if the bite slows after you’ve plucked a few perch from the hole, throw down a smaller lure like a size 10 Lindy Tungsten Toad, tipped with a nose-hooked waxie.

Such a combination often allows you to milk a few more curious onlookers from the hole before moving on to the next drop zone.
