The sandgrass persists through winter and provides cover for postpawn walleyes on sand or gravel flats. Submerged weeds develop as the water warms. Weedy flats hold baitfish that attracts walleyes at night. In fall, weeds decline and small fish are flushed from cover. Walleyes feed aggressively throughout this period.
Walleyes can feed in dim light.
They have a feeding advantage over most prey species after dark. Walleyes often feed voraciously at night. The first-time night fisherman finds a new and unfamiliar world, which at first can be threatening and unproductive. But with proper equipment and background knowledge, night fishing adds a fascinating new dimension to fishing. Although walleyes don't necessarily follow narrow pathways as they enter a flat, a good bet for locating them is to find a stretch of rocky rubble that is adjacent to a steep drop-off.
