Most, if not all experienced anglers consider water temperature as the
single most critical factor governing crappie location and behavior.
This guide will help you pinpoint crappie year-round, so you can spend
more time fishing and less time searching."

Water Temperature: 35 Degrees
Crappie will be holding tight to bottom cover in 30-50 feet deep and tight-
lipped, but they still need to eat and is catchable with the right
presentation. Look for humps or other bottom-hugging cover in or near
main-lake river channels. Fish straight down with a vertical presentation
using small live minnows on a Kentucky rig, or very slowly "bounce" small
spoons jigged just above the fish. Kentucky Rig consist of two hooks about
a foot or two apart with a bell sinker attached to bottom.
Water Temperature: 40 Degrees
Schools of crappie often suspend in open water in 20-30 feet deep as they
begin migrating from deep river channels toward major tributaries, where
they will eventually spawn. Most females will remain on river channel
structure in considerably deeper water. Slow troll as slow as possible
with hook/minnow and a Road Runner with minnow tied on bottom just above
the schools.
Water Temperature: 45 Degrees
Many crappies have started migrating toward their eventual spawning areas.
Target crappie hanging tight to submerged wood on deep channel banks, about
a quarter of the way into the creek arm, 10 to 20 feet deep. Cast soft
plastic grubs or other lures with a vibrating tails to channel bends with
wood. Cast, let the lure sink until it contacts the cover, then immediately
begin swimming it slowly and steadily back to the boat.
Water Temperature: 50 Degrees
The prespawn migration is in full swing, with large numbers of crappies
moving into reservoir tributary arms. The males will make their move
shallower following a few days of mild, sunny weather. Continue targeting
the creek channel migration route, keying on isolated wood cover along
channel bends with deep water nearby, since crappie will insulate
themselves from the impact of frontal passages. Fish with minnow or
jig/wax worm in wood cover as males are preparing the cover for the spawn.
Sometimes it wouldn't hurt to turn around and fish off other side of the
boat with a Kentucky rig baited with minnows or a minnow/tube bait
combination along the channel drop. The females will be hanging there
waiting for the prime time to move in to spawn.
Water Temperature: 55 Degrees
Expect the bite to get more aggressive as crappies begin feeling “the urge
to merge” and feed heavily before spawning. Schools of baitfish continue
to be a primary location factor as crappies fatten up before spawning.
Shallow ditches veering off the creek channel and running toward shallow
spawning coves can hold huge fish. Work the creek channel with curly-tail
grubs or minnows, keying on brushy cover in the 6 to 12 foot zone. Crappie
may be as shallow as 1-3 feet deep along these structures.
Water Temperature: 60 Degrees
Male crappies fan out the nest while the females hang around outside the
cover witing for the water temperature to get a degree or two warmer before
moving in on the beds, and now is a good time to load the boat with oversize
fish. Some crappie may have already started the spawn if shallower water is
warmer. Tightlining minnows and jigging tube baits around sunken cover
will score heavy crappie catches in murky water. In clear water, back off
your target, make a long cast and swim a curlytail grub.
Water Temperature: 65 Degrees
Spawning should be in full swing now, but some will still be in a prespawn
mode. If you aren’t catching quality fish on likely spawning cover, back
off and target prespawn crappies instead. Spawning takes place on woody
cover such as: brush piles, stake beds, etc... in the upper ends of brushy
coves and creek arms, in 2 to 8 feet deep, and some as shallow as 6 inches
deep depending on the lake's water clarity. Prespawn fish will be in
three to six feet of water, but will chase minnows shallower. Tight-lining
minnows on long rods is the standard method now, but target-casting grubs
and tubes to submerged wood works, too.
Water Temperature: 70 Degrees
Some crappies will be done spawning, while others are finally moving onto
their beds. Keep fishing as the spawn is still going strong. Cast tubes
and grubs or tight-line minnows close to cover. If you’re catching small
fish, back off and hit deeper isolated stake beds and stumps for the
bigger females.
Water Temperature: 75 Degrees
While a few lingering crappie may still be spawning, postspawn fish will
hang around bedding areas for several days until the water temperature
rises. Some postspawn fish will be on isolated pieces of cover adjacent
to spawning sites as the males move back in to protect the nests.
Determine the crappies’ spawning mode. If tube baits or minnows don’t
produce strikes in thick brush and stake beds, cast grubs to scattered
wood.
Water Temperature: 80 Degrees
Most crappie fishermen hang up their rods after the spawn, but a shift in
tactics can yield fast action on postspawn fish. Before moving to their
deep summer haunts, many crappies gravitate to the edges of flats, hanging
tight to scattered wood or suspending above the breakline closest to the
structure. Troll small diving crankbaits like the 200 series Bandit
around the edges of flats in the 6 to 18 foot zone, occasionally banging
the plugs off stumps and bottom.
Water Temperature: 85 Degrees
Crappies will be moving out of tributaries via the same creek channel
migration routes they traveled before spawning. Slabs gang up on secondary
and primary points that drop quickly into deep water. Look for them
suspending 18 to 30 feet deep around baitfish schools. Target channel
points using a Kentucky rig bumped slowly along bottom.
Water Temperature: 90 Degrees
Crappies suspend for long periods, and may be sluggish now to conserve
metabolic energy. River-run reservoirs with a flowing channel usually have
better fishing now than calmer lakes. Channel ledges lined with standing
timber or brushy cover offer your best bet now. Crappies are probably
suspending 18 to 30 feet deep in 50 feet of water. You can still catch
crappie in shallow water if you can find shady areas such as lily pads
and over-hanging trees where water may be cooler.
Water Temperature: 85 Degrees
While the lake’s surface temperature cools quickly as the days grow
shorter in early fall, deeper water cools more gradually, so expect to
find crappies deep. Deep channel cover continues to be your best bet for
finding concentrations of fish. Kentucky rigs bumped along cover and
minnows or spoons jigged over wood.
Water Temperature: 80 Degrees
Crappies are following channels, or moving shallow to prey on baitfish
schools, so expect a pickup in activity. Primary tributary points, where
the creek and river channel intersect, can hold a ton of baitfish and
crappies. Target the 12 to 25 foot zone with minnows on a Kentucky rig.
If crappies are suspended, slow-troll jigs, Road Runners, or crankbaits.
Water Temperature: 75 Degrees
Shad move into shallow coves and tributaries to spawn, and crappies follow.
The first half of reservoir tributary arms will hold large schools of
crappies. Target scattered wood along the creek channel 10 to 20 feet
deep, sometimes shallower depending on water clarity. Kentucky rigs with
minnow works well for me.
Water Temperature: 70 Degrees
Crappies follow baitfish back into the tributaries to feed and fatten up
for the winter. Check channels, secondary points and flats in the back
half of reservoir tributary arms. Crappies hold anywhere from two to 10
feet deep, depending on water clarity. Cover water quickly, casting a
curly-tail grub or small shad colored crankbait to every piece of wood
you can find.
Water Temperature: 65 Degrees
Reservoir drawdown usually starts about this time, thus dropping water
levels push baitfish and crappies out of tributary arms into deeper water.
Crappies use the same migratory routes they took in spring to move back
to the main lake. Find them on creek channel cover in the 10-18 feet deep.
Cast grubs or bump Kentucky rigs around creek channel cover.
Water Temperature: 60 Degrees
Colder nights spell a rapid cool-down. As drawdown continues, many crappies
leave reservoir tributaries. Deep points and steep banks at or near the
mouths of tributaries hold large schools of crappies in the 15- to 25-foot
zone. Try slow trolling live minnows on long rods rigged with heavy
sinkers. Lower the sinker to bottom, then reel up to the level of
suspended crappie. The sinkers will help locate cover and prevent hooks
from snagging.
Water Temperature: 55 Degrees
The 60-degree pattern should remain about the same until the lake turns
over. Deep points and steep rock bluffs near tributary mouths hold
concentrations of fish. Slow troll jigs or pull crankbaits through
schools of fish in the open water between the points.
Water Temperature: 50 Degrees
Turnover usually occurs during the fall-winter transition, triggering a
wholesale movement of crappies. Crappies are often tight to bottom
around intersection of channels in 25 to 40 feet deep, and they’re going
to stay that way through the cold weather months, so slow trolling with
vibrating lures could be your best bet along the channels.
Water Temperature: 45 Degrees
Crappies have settled into a winter pattern now, setting up on deep
channel structure. Channels with brush, 18 to 40 feet deep. Fish the
bottom along bends, drop-offs, and humps..
Water Temperature: 40 Degrees
Crappies are deep and feed only sporadically. Look for crappies 30 to 50
feet deep. Fishing spoons along the channel, or hug bottom with your
Kentucky rig.
