Delavan and Geneva are great fisheries. Geneva has a ton of pleasure traffic all of the time, and even with little wind I’ve been rocked in my 19 footer. Delavan isn’t as bad, especially during the week, but both lakes can get rough quick with 15+ mph south/southwest winds, so unless you’re canoeing early I wouldn’t recommend either. I haven’t fished Lake Como as much but if you’re looking for less traffic and waves, this lake may be a better fit for you. All 3 have good fishing, Geneva is a bass factory with monster gills, and Delavan has trophy bass & pike, with good sized panfish. Como has decent sizes of all 3, but not nearly the quality or quantity.
Good luck & tight lines
