Where can I find and catch some around the dfw?
Sunfish are plentiful in the DFW lakes, but none of them hold really big bluegill. Exactly why this is true I am not sure. An 8 inch fish is large for this area. I suspect both fishing pressure and water pollution are factors.
Good eating-sized fish are found in Lake Arlington, Joe Pool, And Lake Ray Hubbard. In general the farther East you go the bigger the bluegill. If you are a serious bluegill fisherman Lake Athens, Bluegill Lakes and Toledo Bend are all good bets.
