Fall might be the most misunderstood season in fishing. Anglers who quit after Labor Day miss the single biggest feeding event of the year. As water cools, bass, walleye, and crappie all sense winter coming and gorge on baitfish for six to ten straight weeks. The catch is that fall also brings turnover, the one event that can shut a lake off completely for a week or two. This guide covers both: how to fish through turnover, and how to cash in on the binge that follows.
All summer, most lakes are stratified into layers. Warm, oxygen-rich water sits on top, a narrow thermocline sits in the middle, and cold, oxygen-poor water sits on the bottom. Fish live above the thermocline because that is where the oxygen is.
When fall air temperatures drop, the surface water cools until it matches the temperature of the water below it. Once the whole column is roughly the same temperature and density, wind mixes the entire lake from top to bottom. That mixing is turnover. It stirs up decaying matter off the bottom, temporarily drops oxygen levels everywhere, and often turns the water murky with a distinct musty smell. Fish that spent all summer pinned to the thermocline suddenly have the entire lake available, and they scatter.
You have three good options when your lake is turning over:
The good news: turnover lasts one to two weeks, and the lake that comes out the other side is fully mixed, evenly oxygenated, and primed for the best bite of the year.
Falling water temperature is the trigger. A cheap digital thermometer, or the surface temp readout on a good fish finder, tells you exactly where each species is in its fall program.
When surface temps drop into the low 60s, shad migrate into creek arms and pockets, and bass follow them like wolves. The 55-65°F window is the best shallow bass fishing of the entire year. Bass herd bait against banks and bust it on the surface. Look for flickering shad, diving birds, and nervous water. When temps slide below 55, bass drift back toward channel swings and steeper structure, but they keep eating.
Fall walleye slide shallow after dark to ambush baitfish on rocky points, riprap, and shallow flats next to deep water. The colder it gets, the bigger the average fish. Trophy hunters circle late October and November on the calendar for a reason: the biggest females of the year come from casting stickbaits over shallow rock at night in 45-50 degree water. Slow, steady retrieves with long pauses outproduce everything else.
Fall crappie behave almost like they do in spring, minus the spawn. As water cools through the 60s, they group into big schools around brush piles, standing timber, and bridge pilings in 10-20 feet. The schools are tight and stacked, so one good waypoint can produce a limit. Side imaging and down imaging shine here; graph the brush, then hover on it with a jig or minnow.
Early September still fishes like summer, but the first cool nights start the shift. Surface temps fall out of the high 70s and bait begins edging toward creek mouths.
October is to fall what May is to spring: the month everything peaks. Once a lake finishes turning over, expect two to six weeks of aggressive, shallow, catchable fish.
Fewer bites, bigger fish. Water temps fall through the 40s in most of the country, and the feeding windows compress into a few prime hours, usually midday when the water is warmest and around major feeding periods.
Two rules drive fall lure selection. First, match the shad: threadfin and gizzard shad have grown all summer, so bump up your bait size. Second, until the water drops below about 55°F, fish faster than feels comfortable. Fall fish are chasing, and a fleeing bait triggers strikes a crawling bait does not.
Fall location boils down to one sentence: find the bait, and stay near the migration routes.
Fall fish follow bait that moves daily, so electronics earn their keep more now than any other season. A budget unit like the Garmin Striker Vivid 5cv will show bait balls and mark brush. Side imaging on a Humminbird Helix 7 CHIRP MEGA DI or mapping on a Garmin ECHOMAP UHD 74cv lets you scan whole creek arms in minutes instead of hours, and a big-screen unit like the Lowrance HDS Live 9 pairs mapping and imaging side by side. Idle the creek arm first, find the bait, then fish. A quiet electric motor such as the Minn Kota Endura Max 55 helps you slip along shallow banks without spooking the school, and a GPS anchor model like the Minn Kota Terrova 55 (i-Pilot) will hold you on a crappie brush pile in the wind.
Fall Pro Tip: Wind is your friend in fall. A steady wind piles plankton, then bait, then gamefish onto the windblown bank within hours. If it is blowing on a flat near a channel, fish it before you fish anything else.
Check solunar periods, weather, and conditions at your favorite fishing spot.
Check fishing conditions near you →The 55-65°F window is the overall sweet spot. Bass chase shad shallow, crappie school on mid-depth brush, and walleye begin their night bite. Below 55, action slows but average size climbs, especially for walleye.
The active mixing usually lasts a few days to two weeks per lake. Fishing is toughest during and immediately after mixing, then improves rapidly once the water clears and oxygen levels even out. Rivers and very shallow lakes skip turnover entirely.
Unlike summer, fall often fishes best from late morning through mid-afternoon, when the sun has warmed the shallows a degree or two. The exception is the walleye night bite, which starts at dusk. See our feeding times by species guide for details.
No, the opposite. The first frosts kick off the heaviest feeding of the year because fish sense winter coming. Many anglers catch their biggest bass and walleye of the season between the first frost and ice-up.
