The articles for this series of books, Keys to Catching Georgia Bass, were written over a span of 18 years. Conditions change but bass tend to follow patterns year after year.
For example, Lake Lanier has gone through a series of years with low water then full again. Landmarks you can see when the water is very low cannot be spotted when the lake is full. But humps, points and rock piles are still there, in the same place, just underwater.
Some years the water is clear and some years stained to muddy during the same months in some creeks, but the main lake is almost always clear. The patterns and places in these articles will still work in the creeks, but you may need to adjust the color of the bait to the conditions.
New baits and tackle companies come along every year but you can always find old favorite baits or similar baits from a new company that were produced by a defunct company, or use the new ones that are similar in action.
The GPS Coordinates given for each spot will get you very close to what you want to fish. An old brush pile on the coordinates may be gone, but you can bet another one will be in the same place or very nearby.
Some spots are on more than one map for more than one month. That guarantees it is a good spot, if more than one good fisherman chose it! Some spots are good year round, over many month.
Some of the expert fishermen providing information for the articles in this book are not named for a variety of reasons.
