Hey fishingsheep,
I've fished Shabonna lake only once -- used small minnows off shore fishing for Crappie -- we caught a bunch. That's about all the info that I can give ya. There are definitely some good fish in there, I remember watching I think it was called "Outdoor Notebook" an outdoors fishing show that had an episode about Shabonna, and this guy who pulled out the new Illinois State record (I don't know if it's still the record though). Good luck, and yeah i hope someone can give you more help than me, lol
