This is my home lake and the fishing is beginning to pick up. Hopefully with cooler weather moving in next week and the tail end of Katrina coming up this way presenting some good possibilties for fresh water. Bass have been difficult and crappie also tough. Have been catching numerous crappie that are fat but short. The white bass have moved up on some of the wind blown banks and are hitting the double-rigged twister tails, Little Georges and in-line spinners.
If you decide to come to Shelbyville let me know & I'll try to put you on some good spots...not said try...LOL
