In southern Minnesota, the ice goes off the lakes sometime in late March or early April. As everywhere else, the first shallow movement of crappies is largely determined by weather, and the “window” is expanded to a period that spans almost a month to accommodate the wild vagaries in weather at this time of year. At any point after the ice leaves, hot fishing can occur in depths of 2 to 5 feet in northern natural lakes. Sometimes we catch fair numbers of them in 5-foot depths through the ice in March, back in those black-bottom bays they invade every spring. But if the weather stays blustery and cold, fishing will be poor. The first “shirtsleeve days” after the ice recedes are the prime indicator. Stable weather during a warming trend—that’s the key to early-season crappie success everywhere.

The day after the ice recedes from a lake, the temperature out in the main lake typically registers right around 40°F, unless the weather really turns sour, in which case crappies turn off and suspend beyond the first major drop-offs. Stable, warming weather is a different story. A shallow, dark-bottom bay on the north side of a lake, where the sun hits the water for the longest period during the day, can warm quickly into the high 40°F range. If so, the crappies will arrive before you do. When a cold front hits, crappies back out of these bays and revert to staging practices. It’s typical to find them suspended 10 to 20 feet down over depths of 20 to 30 feet, just off points, bars, or channels leading into the bay.

Another pattern involves canals and marinas, where shallow water leads into protected areas. Canals can be natural or artificial, where paths have been dredged into a condo complex or group of homes to create boat slips. If the construction has only one way in and one way out, wind and convection currents can’t blow the warm water out. These spots can produce some of the most sustained and consistent bites right after ice-out in the North Country, which also serves to prove a point: Crappies seldom spawn in marinas and boat-slip canals, suggesting that the first movement to shallow water is a foraging movement, not a true prespawn activity.

The earliest bite can be slow, so it requires slow, subtle presentations. Light 7-foot rods, 2- to 4-pound line, tiny jigs, and tiny minnows or maggots tend to produce best. Things can warm up quickly, in which case the window opens in early April. If cold weather persists, the window may not really open wide until early May. The time to be there is when the water hits 50°F, which can be hard to plan for. At that point, crappies reach their highest saturation point in those early foraging zones, and the hot ticket becomes a 1/32-ounce jig with a plastic tail on 4-pound line. Casting and slowly retrieving a jig with a 2-inch action tail can put 50 or 60 crappies in the boat in short order in Mississippi River backwaters between Red Wing, Minnesota, and La Crosse, Wisconsin.

Farther north, the window opens even later. Perhaps the hottest crappie bite in the North in recent times has taken place on Red Lake in Minnesota. Big black crappies roam this vast northern lake in huge schools these days. It’s a shallow lake, with gradually tapering shorelines. Once crappies commit to the shallows, they have a long way to go to retreat back to deep water, and usually only back off into the 10- to 12-foot zone.
