galena lake has them but i think its catch and release or you can keep 4 over 10" or something like that . you generally won't find them in there by themselves. expect to catch gills and crappie out of the cribs. i've heard that fitzgerald lake near hanover may have some. Lake summerset in davis has them.
there are a few in iowa....i can't put my finger on the name...it deer path or goose lake....can't remember.
but like i said, the big lake at the bottom of pool 13 is the closest.
