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.
