Re: lake tawakoni Blackbass??????
I would try a rage tail shad on a 5 ought wide gap hook. Run that puppy at different depths starting shallow and going to about 5' deep and as parrallel to the bank as you can get. Vary your retrieve and even stop in once in awhile. Do this toward evening around any stumps you can see.
Maybe, if you catch her in the right timeframe, you will put the first fish from that lake into the share a lunker program...
I caught a 4 last night off the bank using this technique in Lake Houston and it it is fairly similar to your lake; stumpy, no grass, fairly shallow etc...
