I have the same problem. Located near WI border, as well. McHenry County. Fishing the Fox, and nada. I was using carolina rigs, texas rigs, cranks, soft plastics, spoons, jigs. Anything I had was on the line, and maybe a bite. But I am pretty sure it was snags.
If anyone figures this out, please keep me posted. I did not try live worms. I am unsure of how to fish them without a bobber
