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.

“If you had to pick one week to spend here,” suggests Don Hudek, owner of Hudek’s resort on Red Lake, “it should be about the first week of May. The fishing is consistently good at that time of year. During a cold spring, May 1st represents the first really hot shallow bite. In warm years, it will be the middle of the spawning run. Either way, the weather’s usually getting nice by then.”

From ice-out through the spawn, slipbobbers, light jigs, and minnows are most popular on Red Lake, but Hudek fishes on bottom. “I like a floating jig and a minnow on a Lindy Rig.” This is basically a sliding sinker ahead of a 1- to 3-foot leader. “It’s more versatile,” Hudek says. “You can cast or drift to cover more water, and the fish are shallow (generally 4 to 8 feet), so they won’t be too far from bottom most days. Most of the areas the crappies use are pretty featureless, and weeds are rarely a problem early. A sudden 1- to 2-foot drop in the bottom is significant and can collect hundreds of crappies.” A minnow can be tail-hooked on a small floating jighead. When the rig is left to rest on bottom, the floating head holds the minnow up, struggling against the jig to reach bottom—a powerful trigger early on.

Just across the Canadian border, the window finally closes once and for all, but not until mid-June. People from down South are always shocked to find 2-pound crappies this far north, and Rainy Lake has a ton that size. Rainy Lake sprawls across the international border between Minnesota and Ontario. “It’s a pretty big window up here,” according to Barry Woods of Woody’s Fairly Reliable Guide Service. “It can happen in the first week of May or the first week of June. It all has to do with water temperature and weather. Water temperature is pretty warm when the crappies move in really shallow, right around 50°F. On Rainy, the first hot shallow bite can take place in pencil reeds or on shallow rockpiles. I look for them first along the north shore of shallow, weedy bays. If you can find steep, marshy banks with overhanging brush along those northern shorelines, that’s good. If you’ve got a proven rockpile, sit right on it. You might not see anything for several hours and suddenly, there they are. They seem to move in and move off several times over the course of the day.

“You have to have several warm days in a row to trigger them,” Woody says. “Another method for locating them is to work along reed lines and dap with 20-foot poles and 6-pound line, because sometimes they move right into areas 1 foot deep that you can’t cast to. I prefer to use 2- to 4-pound line out on the rockpiles. Makes it sporty. You don’t need a slipbobber. They’re not that sensitive. When they’re ready, they start eating, and they’ll pull a beach ball under. A tail-hooked minnow on a light jig is the standby, but a tube or puddle jumper works really well, too. Sometimes isolated reedbeds, out in the middle of nowhere, produce the hottest bites. Where reeds are sparse, a Beetle Spin or Mepps spinner works really well, too.

“Crappies run a pound to 11⁄2 pounds, and it’s common to catch a few 2-pounders. Occasionally we catch one over 17 inches. They start to spawn in water temperatures in the low 60°F range, here. The water doesn’t even reach 70°F until July most years. In the river sloughs and backwaters leading into Rainy, the timing is the same. Be here early May to early June, find a beaverhouse in black, marshy water, and fish the groove that beavers create in the bottom leading into the house. The water is cloudy and crappies feel rather safe. Occasionally you can really pound them in there. On Rainy Lake, you have to find the right bay. You’ll know when you find it,” he says, “because crappies literally take over the shallows once the weather stabilizes.”

Somewhere north of Rainy, the natural range of the crappie comes to an end. Dotted throughout this near-wilderness are little lakes and rivers that represent the final frontier. Long lifespans allow crappies to grow huge up there, many living out their lives without ever seeing a hook. Most of the locals could care less about crappies up there, what with giant walleyes, pike, muskies, and smallmouths surrounding them in every direction. Pinpointing the time when crappie fishing first heats up early in the far North requires a little more research before you go.
