River currents prevent these waters from freezing when flatwater impoundments are ice-covered. With careful presentations, river largemouth can be caught. First, look for areas with minimal current where bass move for the winter. The upper ends of backwaters or dug-out ponds and harbors off the main river are prime locations. Fish a finesse jig with a bulky trailer that slows its fall while providing action when you deadstick the bait. Target deeper pockets where some grass remains, or where stumps provide cover.
