Rivers of all sizes offer serious opportunities to hook up with fall walleyes. Across Lindy Land, cooling water temperatures and shorter days trigger the fish to school in predictable places for their annual autumn feast.

Relatively small, free-flowing rivers offer some of the most overlooked action. Examples include Minnesota’s Rum, upper Mississippi and Prairie rivers, along with the border waters of the upper St. Croix, lower St. Louis and Rainy, but you can find similar slices of paradise around the Walleye Belt.

Perennial hotspots in these systems frequently include holes scoured by strong currents during high-water events earlier in the year.

Corner holes carved in outside bends are some of the best, particularly those adjacent to long reaches of shallower water where walleyes feed once darkness falls. Deep pockets below bridges, chutes and other structure are also worth checking.

Depth is relative to what the system has to offer. In some rivers, eight feet is a deep hole. Where strong current boosts the water’s power of erosion, you might be looking at 15 feet of more.

Medium-diving crankbaits like Lindy’s Wally Demon are great options for fishing these holes, either from the bank or a small boat, canoe or kayak.

Position yourself on the inside bend and cast to the far side of the hole at a 45-degree angle upstream. Retrieve the bait through the hole, so the current sweeps it downstream and your bait ends up at a 45-degree angle below your position.

Leadheads like a Lindy Watsit Jig or Fuzz-E-Grub work wonders, too. Experiment with just the plastic trailer and adding a live minnow or chunk of nightcrawler. Use the same casting angles and skip the jig along bottom as the flow washes it down-current.

Such strategies produce banner catches from the Labor Day holiday weekend throughout the fall, so be sure to add river walleyes to your hit list for final leg of the open-water season.
