To find winter crappie, use your depth finder to look for submerged creek and river channels in 15 to 40 feet of water. What you're looking for is brush or submerged trees along these channels. Crappie will be holding somewhere in or around that cover. Crappie, like bass and most other species, almost always stage close to some type of cover, and they seem to prefer brush-piles or submerged trees as their cover of choice. Underwater ledges next to deeper channels may also be holding a few crappie, if there is some type of cover nearby. If a warm front comes through and the temperatures rise for a few days, crappie may begin to move up to flats along the creek channels. If that happens, you may want to go back to slow-trolling, as the fish will be more spread out.
Often during the winter, wind can be a problem for fishermen. If you have a good trolling motor, you can keep your boat positioned over the cover and drop jigs into and around it. I hate fighting the wind, so I usually use an anchor to keep my boat where I want it. When I find the cover on my depth finder, I'll drop a marker buoy over it, then determine the wind direction. I circle the boat around, and when I'm upwind and off to the side of the buoy, quietly drop my anchor. When it hits bottom, I let the boat drift alongside the marker buoy, and then tie off the anchor rope. I will then be able to concentrate more on fishing than constantly repositioning the boat.
Marabou and feather-type jigs can be very effective for winter crappie, as well as "umbrella" type jigs. The slower rate-of-fall seems to be the trick with these. Whatever type of jig you choose, just remember to fish it very slow.
On a clear, sunny day use light colored jigs, and on cloudy days you can go with a darker color, but I prefer a white, yellow, light green or chartreuse color. The same rule applies to water clarity, in clear water use very light colors or even clear with some sparkle. In stained water, use a darker green or chartreuse. There are so many different color variations nowadays it can be overwhelming trying to pick the "perfect" color. with colors like "bayou booger", "firecracker", "woodpecker" and "electric chicken", everyone today seems to have a different favorite. The way I do it is try a few different color combinations at first, fishing with 3 or 4 separate rods, and when I seem to be catching more crappie on a particular color, stick with that color.
When ice fishing for crappie, fish over the deeper brush piles you found in the spring, summer or fall. The crappie will be holding tight to this cover, Their lower metabolism in the cold water means they won't venture far from it when foraging for food. This also means that they will often readily inhale a jig when they see it, not passing up an opportunity for a morsel of nutrition. The trick here is, if you catch a few crappie and then the bite stops, move and drill another hole over another brush pile.
If you are using any of these methods and are catching a lot of crappie, but all of them are small and not keeper size, go to a bigger jig. Sometimes the larger fish will only strike at larger baits, letting the little guys eat up the small stuff. If I'm catching nothing but little ones, I'll switch to 2 inch jigs. Often that will get the "bigguns" to react.
I hope that by using these winter crappie tips you can go out and catch yourself a nice "mess" of crappie, just remember to adhere to the game and fish laws, slot limits, daily limits, etc. Another thing to remember is to bring adequate clothing for the temperature, keeping the wind chill factor in mind. You don't want to be miserable while out on the water, and you can always take off a layer of clothing if you get too warm. Check the weather forecast before you go, pay attention to the wind speed, and dress accordingly.
Good luck, and have a "happy crappie day!"
