If you don't mind paying a guide fee, I can put you on a TARP bluegill and it would probably take all of an hour or less. Although you would also be at risk for catching an 11" or 12". There are also shellcracker in these ponds, and if you catch one it will probably be a TARP.
The three biggest caught by clients of mine last spring went 1.6, 1.91, and 1.99 lbs. I had one party that I lost count at ten of bluegill over twenty ounces. I'm attaching a few photos.
By the way, this is just outside Columbia...
