CJ (criminal justice) -- you probably are right on the warmouth and the abundant bass. A lot of the black and white crappie state records come from ponds, too. Often, the records come from ponds where the owner didn't even know they had that species (Don Gabelhouse found that out while working on a lmb-crappie study for the Central States Small Impoundment Work Group quite a few years ago). Anyway, low density, plenty of bass, and an occasional catch of a large sunfish or crappie is probably right.
Thanks everyone.
