I live in Granbury. I got hooked on catching blue cats last winter, with several large fish from Waco, Whitney, Tawakoni, and BB. I do pretty decent locating and catching on those lakes. I spent MANY hours on Granbury, with very limited success. I caught numerous large channels in the 5-15 lb range, and several small 2-5 blues. Probably averaged 10-1 channel to blue. Largest blue was a 16. Standing offer to pay for gas food beer for one of the "experts" (you know who you are) to come down and see if you can find these things on Granbury. Here is the Granbury stocking from TPWD- Catfish, Blue 1991 86,343 Fingerling Catfish, Channel 1993 300 Fingerling Catfish, Channel 1969 374,675. 86k worth of Blues in 91 should mean there are some hogs swimming around. It is difficult to cast net up gizzards, fairly easy to get threadfin and carp. Or we can go in my boat and all you have to do is drive down.
