In the heart of winter, bass behavior in the Tennessee River system is influenced by several factors, including water temperature, current, and the seasonal drawdown of water levels. Based on the video context provided, here's a summary of winter bass behavior in this region:
Drawdown Conditions: During the winter, the Tennessee River experiences a significant drawdown, where water levels are reduced by about six to seven feet. This drawdown concentrates the fish by reducing the available habitat, making them easier to locate. They tend to congregate around structure that's still submerged, such as the mouths of ditches, main lake points, island tops, humps, and any irregularities in the bottom contour.
Current-Driven Behavior: Bass in the Tennessee River are current-driven, meaning they respond to the flow of water. Even with lower water levels, they still relate to areas with some current, such as the first break line or current seam.
Shallow Water Preference: Despite the cold, bass in the Tennessee River system can still be found in surprisingly shallow water. They are river fish that prefer shallow areas year-round. After a warm rain, feeder creeks can introduce warmer water into the system, attracting bass to the mouths of these creeks where the warmer water mixes with the main river.
Temperature and Cover: In winter, bass will seek out areas that can provide a slight temperature advantage. Mud flats, for example, can hold heat, which might make them attractive to bass. Additionally, remaining grass lines, rock, and wood can also hold heat and provide cover for bass.
Finesse vs. Reaction: When bass are found on flats or in deeper areas, they are often targeted with finesse techniques due to their slower metabolism and reduced activity levels. However, if they are located on the lip of a drop-off or in shallower water, they might still respond to reaction baits.
When fishing for bass in the Tennessee River during winter, it's crucial to monitor water levels and temperature changes, focus on areas with remaining cover and structure, and be prepared to use both finesse and reaction tactics depending on the location and activity level of the fish.
