To prepare for colder weather, bass like to stock up on nutrients in the body by following shads to shallow waters. They can be found where bait creatures are in abundance.
Know the body of water that you're fishing in to determine the more shallow areas. It would also be best to prepare crankbait that resembles shad or minnow. The right techniques make fall bass fishing a breeze.
Bass like to go to deeper waters in the winter, preferably deep enough to escape fishers and predatory fish. If the water body isn't deep enough, they'll hide under rocks or plants.
The key is to make the baitfish look injured so the bass believes it won't need to use much energy. A jigging spoon lure should do the trick.
One of the most important things to understand is the water body that the bass live in. This will determine your success in fall and winter.
