A good topographic map can be a pivotal tool for locating bass on flooded waterways. "It helps you see the major pathways and areas of the lake that have big bass populations whenever the lake is at normal level," suggests Jones, who avoids fishing areas that lack habitat at normal levels. Turbidity poses a problem during flooding conditions, so Jones searches for areas with the clearest water. He avoids fishing a reservoir's main tributary or major creeks because muddy runoff flows into these watersheds after heavy rains. The upper end of a main tributary usually features flat terrain and, during flood stage, the waters spread over too vast an area. So Jones concentrates on the lower section of a lake, where the water becomes more contained by the steeper shoreline.
