By far the best is Lake Barrett for pure bassing fun. If you can get a
ticket. It's a whole day thing though. 20-30 bass days are not
uncommon, they are generally up to 4 pounds.
See the SDfish.com Lake Barrett board.
I've fished the other lakes in SD extensively as well, and they can be
decent or tough. Calico fishing in the kelp always seems to be my
option instead
