Lipless crankbaits that mimic shad are excellent for covering water near bait schools. Crank them fast, with occasional jerks, to entice hungry bass.

Catching a bass on every cast is mostly an angler’s dream. However, for a brief time each fall, it can become a reality on Midwest lakes where largemouths school on young-of-the-year gizzard and threadfin shad. The giant swarms of bait—thousands of fish 1 to 4 inches long—are perfectly sized for a bass banquet. During winter, feeding slows to a crawl, so as bass feel the approach of cold weather, they eat heavily knowing they have to survive on accumulated energy from fall.
Gizzard shad are by far the most abundant of the two shad species in the Midwest, endemic throughout the Mississippi River basin and on many other waters. The gizzards hatched last spring are just the right size for most adult bass to eat as fall arrives, and their massive schools create a feast that persists for weeks in many lakes and rivers.
Threadfins are less common this far north, as they don’t do well in lakes that freeze over. However, they’ve been stocked in the southernmost waters of a few Midwest states, and they thrive in most Missouri waters. Their adult size is commonly about 4 inches, so they’re permanent bass fodder wherever they’re abundant.
With FFS, dance jigs above bass on shad schools. Minnow-style baits, like Rapala’s CrushCity Freeloader or Mooch Minnow, work great.

Most large schools of shad have bass nearby, even if they’re not actively feeding on them when you get there.

Gizzard shad feed mostly on bottom in waters that have a high nutrient level and are somewhat murky or muddy. Threadfins, on the other hand, often chase free-swimming zooplankton, so they usually prefer clearer, more open water and a firmer bottom. But in lakes that have strong populations of both, pretty much any bay with comfortable water temperature—60 to 75 degrees or so—may hold large schools.
Anywhere water temperature drops below about 55, threadfins are likely to be absent. They avoid cold water, and they die if it gets down into the 40s. Gizzard shad, on the other hand, can survive even in waters that fully ice over each winter.
GEAR UP FOR SCHOOLS Schooling bass can be caught on topwaters, mid-depth lures and right on bottom, depending on where bait is concentrated. In general, though, fish feed “up,” so you want a lure that stays just above them.

When fish are on top, it’s pretty much a no-brainer because they will blast just about any topwater that looks remotely like a shad. Among the best are the Berkley J-Walker and Cane Walker and the noisy Berkley Choppo , which provokes some spectacular hits. Rapala’s X-Rap Pop and Rebel’s venerable Pop-R are effective popping lures, and the Strike King Wake Bai t and Wake Shad are both great for slow-waking.
After the topwater flurry subsides, there are usually plenty of fish still in the same area. You can see them if you have forward-facing sonar (FFS), of course. However, it’s not necessary most of the time because a fast-moving vibrating shad imitation like the Rat-L-Trap , SPRO Aruku Shad or Cotton Cordell Super Spot will search them out promptly. Crank it fast, with occasional hard pulls to make it dart and flash.
If you have FFS, pick out larger targets within range. Then tease them with a 1/8- to 1/4-ounce jig rigged with a small soft plastic like Rapala’s Crush City Mooch Minnow or Yum’s FF Sonar Minnow . Deliver the bait to just above their level and, by steadily twitching the rod while slowly retrieving, make it dance and quiver like a stunned shad. When the targets converge on screen, you’ll feel the “tap” and the fun begins.
Small chrome crankbaits that dive 3 to 6 feet also work. The Strike King 3XD and Berkley Bad Shad are among many good choices. Rather than straight cranking, try a long pull and then hesitate, letting the lure rise briefly before the next pull. This works really well where there are scattered weeds because the pulls help clear any debris on the hooks.
Finally, when you’ve exhausted the bite on surface and midwater lures, plumb the depths with a flutter spoon like the 1/2-ounce Acme Side-Winder or LiveTarget Flutter Shad . Both have a crazy, rocking fall that really turns on bass looking for wounded shad. (Keep slight pressure on the line as the lure sinks. When you feel a tap or any variation in the drop, set the hook.)
Lipless crankbaits can also be fished this way. Let them sink and be on full alert for a tap. Then retrieve in a series of sharp upward snaps followed by a fall back to bottom.
Schools of shad are easily seen and marked on live and 2D sonar while cruising. Also watch for birds and surface disturbances. (Photo by Frank Sargeant) LOOK FOR CLUES Schooling frequently occurs in large bays or near causeways where shad swarm thickest in fall. Fortunately, a school of shad is very easy to see on conventional side-imaging and live sonar. They appear as a large, bright cloud on screen. Run your lake at about 25 to 30 mph, mark as many of these schools as you can on GPS and then return to fish them. Some will surely have bass around them.
Shad sometimes make themselves obvious by feeding at the surface. “Shad ripples” look sort of like a moving rain shower sweeping across the surface as thousands of them swarm to the surface to grab tiny zooplankton soaking up the sun. Both young gizzard and threadfin shad do this, but the gizzards move more to grazing on the bottom as they get older.
Shad also sometimes do an odd “flip” at the surface—mostly single fish—and this occurs on calm sunny days as the water chills into the 50s each fall. Whether they’re coming up to get a gulp of warm air or maybe just grab a final copepod or other minute bug, it’s pretty obvious when you see it. There are often bass below when you spot this behavior.
Of course, the most obvious way to find schooling bass is to actually see them exploding into a school of bait they’ve chased to the surface. This is some of the most exciting bass fishing you’ll ever enjoy. You may see multiple fish blasting baits clear out of the water, and the action can sometimes spread over hundreds of feet of the surface in lakes with high populations of shad and bass.
Birds can also help you find schooling bass. When bass drive bait to the surface, gulls and cormorants are quick to take advantage. Keep an eye on the sky, and if you see multiple fish-eating birds headed in one direction, follow them. Odds are there’s a baitfish bonanza waiting for them.
As the water chills, warm-water pockets may also attract shad schools. Lakes that have generating stations on them sometimes concentrate bait where the heated water flows back into the lake.
Just be aware that both the bait and the bass are likely to be boat shy, so don’t pull up right on top of them and start casting. Shut down about 100 yards out and ease in on the trolling motor or with the wind, and keep your distance from the bait ball. If you get right on top of them in less than 20 feet of water, they’re likely to move or disperse, and the bass will go with them.
SCHOOLING SWEET SPOTS Hit these prime Midwestern lakes for hot-and-heavy action on hungry bass. Several Missouri reservoirs, including Lake of the Ozarks, offer phenomenal fall fishing for bass keyed on shad. (Photo by © Jonmanjeot/Dreamstime) The Midwest is blessed with many waters offering solid schooling action in the fall, especially in more southern stretches of the region. Some of these are powerplant lakes, and most are manmade reservoirs, but all have good populations of gizzard or threadfin shad—or both. Below are several top Midwest options.
HAWKEYE HOT SPOT Iowa doesn’t have a lot of lakes where shad are the primary bass food, but 5,400-acre Saylorville Lake qualifies. Shad-imitating crankbaits worked around rocky points and breakwaters produce good catches in fall.
HEARTLAND HEAVYWEIGHT Gizzard shad are the main forage base at Kansas’ 2,600-acre La Cygne Reservoir, too. Here, the shad and the bass school around the powerplant outflow on chilly late-fall mornings, per Kansas Department of Wildlife and Parks. You should head there as well.
MISSOURI MAINSTAYS The Show-Me State is the promised land for schooling bass action in the fall. Most Missouri lakes contain both shad species, and the bass form large wolfpacks to attack them as fall arrives. Lake of the Ozarks, Table Rock Lake, Truman Reservoir and Bull Shoals Lake are all loaded with shad and have terrific school bass fishing in fall from top to bottom.
PRAIRIE STATE POWERHOUSES Illinois’ Kinkaid Lake, known for its muskie population, also has good school bass action in fall. Shad stockings have benefited the largemouths here with about 25 percent of the population more than 16 inches long per the Illinois Department of Natural Resources (IDNR). Newton Lake, which is warmed by a powerplant outflow, has populations of both gizzard and threadfin shad, and is a fall schooling bass hot spot, too. In 6,965-acre Crab Orchard Lake, gizzard shad are the primary forage, and bass frequently home in on them.
