This summer I have a trip planned to visit Castle Rock lake in Central Wisconsin. Mostly crappie and walleye will be targeted, but I was wondering if anyone knew any good places for Smallmouth? I have caught small smallmouth near what is called the "Ditch". It is quite shallow but with a rockier bottom, contrary to the lakes mostly sand bottom. Mostly of time I only catch whitefish, catching the smallmouth on accident. Should I try to fish the ditch, or look in other areas?
