Fall will officially begin in three weeks. Fall fishing is not always predictable because it's a transitional time for bass. It's like a mystery you have to solve. Solving a mystery takes time.
The weather plays a big part in where and how you fish. With unseasonably warm weather the bass can still be anywhere from shallow to deep.
Every lake, big and small, has its own unique features. If I were fishing Lake Fork in early fall I probably would target the mouth of a big creek. Bass will be following the shad, so I would begin looking for a creek that comes close to a timber line in the mouth of a major cove. It's a place to start.
Almost everyone knows that when the surface temperatures begin to drop more and more the shad tend to migrate up the creek. To find the bass I would simply begin at the mouth of a creek and work my way towards the back. I would keep my eyes on my electronics and scan the surface looking for signs of shad.
When you locate big schools of shad — be it midways or in the very back of the creek — you will find bass near by.
It you're fishing a much smaller lake you will probably have to do a lot of searching. It's always a process of elimination. You may have to fish points, ridges, humps, etc. And any cover you find, be it grass, lay-downs or rock piles.
Remember that bass are in transition, and you have to keep moving around a lot until you either locate the bait fish or develop a pattern. One day the bass may be deep, and the next day you may discover that bass are holding in about five feet around boat houses or other cover.
