In-Fisherman has long maintained that some of the best and least pressured crappie fishing on the continent can be found in rivers, backwaters, and “river run” impoundments (flowages). Many of our Top 10 crappie selections over the years have been river sections, including the Rideau River in Ontario, the Mississippi River along the Minnesota-Wisconsin border, and oxbows in Mississippi.

River specs are an overlooked commodity, perhaps because river fish behave somewhat differently from their still-water cousins. Movements are more dramatic. Migrations of many miles are common among populations of river crappies, but uncommon among most populations in natural lakes. And river crappies are quicker to adapt to adversity, since water-level and water-quality fluctuations are far more dynamic in rivers than in lakes. River crappies also tend to be more active after cold fronts, tend to fight harder, and often move more than lake dwellers.

If asked to describe the ideal shape for a river fish, no one would consider the crappie. A short, flat-sided creature that can be swept 30 feet downstream before it can twitch a fin should not make a good river resident. But crappies do quite well in rivers, thank you, because they’re master adapters. They feed on what’s most abundant, from crustaceans to insects to minnows. If it fits into that big paper basket of a mouth, it’s lunch. Location is often determined by finding the easiest forage crappies can utilize, and that tends to be the forage of greatest abundance in the right size during the season at hand.

While not perfectly suited to current, crappies adapt by avoiding the main flow most of the time, especially during cool- and cold-water periods. But current is where the food is, especially during summer, when water levels and current speeds drop. So from the late Prespawn Period or early Postspawn Period until fall, crappies typically favor current off the main channel. Where they have fewer choices or where current is relatively weak, they may hold near the main flow. The current breaks crappies choose vary in size and type from one river to the next, due to variations in current speed. In brawling waters like the Mississippi River, they don’t fare well in the main river but flourish in backwaters and oxbow lakes. In the slow, ambling creeks of the flatlands, the fish thrive in the main stream behind minimal current breaks.

But, come winter, crappies in flowing water everywhere tend to seek backwaters, oxbows, pools, marinas, reservoirs, connected lakes, and other areas completely out of the main flow. In fact, the farther they can get from the main flow the better. So, current presents problems for crappies. Yet some populations shun the option to stay in reservoirs and lakes during the warmer months, preferring instead the feel of water sweeping across their broad sides and becoming true river fish.

Crappies maintain a unique relationship with current. Flowing water places more restrictions upon them than it does trout, smallmouths, walleyes, or catfish. Finding them in a river system involves understanding those restrictions. Though crappies may move more in rivers, summer habitat tends to be within 3 miles of spawning habitat. Understand the habitat they require during winter, the habitat they require for spawning, and the amount of flow they can tolerate at any given temperature, and finding them becomes much easier.

Small Rivers and Streams

Joe Monteleone is among the more highly regarded anglers in our In-Fisherman databanks under the classification Riverine rodentia (river rat). He lives in Tennessee, near rivers large and small. One of his favorites, the Stones River, is relatively small and slow. In such environs and at that latitude, crappies live mostly in or near the main river channel all year.

Stones River feeds Percy Priest Reservoir, yet crappies inhabit it year ’round.

“These are true river crappies that rarely drop down into Percy Priest,” Monteleone claims. “In some places, the river can be waded across, while other spots are 35 feet deep. Most years, heavy current occurs only in spring during the rainy season, which is when crappies burrow deep into cover near the bank to avoid current. Otherwise, current is rarely strong enough, or the temperature low enough, to sweep fish out of the downed trees in the main flow.”

In spring, crappies move off ledges bordering the deep pools where they’ve spent the winter. In high water, they probe deep into shoreline cover. As the water warms above 60°F, they move to small backwaters to stage. “They won’t spawn in current,” Monteleone explains. “They use little backwaters. Stones River has no big embayments or sloughs or oxbows, just little cuts about the size of an average driveway. Crappies use these to avoid the increased current of spring and to get more sun, then stay to spawn.” As in most river environments, peak spawning activity takes place in water temperatures of about 66°F to 70°F. Crappies find whatever cover they can to spawn within, which typically means woodcover, in river environments.

After the spawn, when water levels fall, crappies move directly to summer habitat. By August, the Stones River might reach the mid-80°F range. “Depending on current, wood becomes critical for crappies in these small flatland rivers,” Monteleone says. “Stones is full of downed trees, stumps, and logs. Crappies prefer to have deep water nearby, but their main objective is to get out of the current and out of the sun. They favor the down-current side of woodcover—spots where weeds adjoin woodcover are perfect. Riverbends become key spots, too; they group on the inside of the bend where the current is reduced. Find woodcover on an inside bend, and you’ll find slabs in summer.

“Crappies tend to hold at different depths according to water level, but generally hold in areas 5 to 8 feet deep on the down-current side of fallen trees. By midsummer, as the river drops and current slows, they move out to 10- and 12-foot depths in large pools. Yet when they seem to be suspended in open water, wood is usually nearby. In the Stones River, crappie location is almost always associated with wood. If bait is abundant in an area, a simple stump or two can hold a lot of crappies. But the cover generally has to be able to provide a current break for pretty good numbers, because crappies have a social side and tend to school.”
