I’d recommend looking at Madison Lake. There are campers north side but I never looked at seasonal prices. It’s busy weekends and summer, but less stink and better structure. I’d fish it year around…nearly always a bite going on. Good bass and pike size structure. Lots of panfish for eating or feeding pike and bass.
Other than that go north for clean water.
Actually I’d check out Pepin, Wisc. Mississippi River. Giant pike and Smallies….you’ll have a blast. Panniers just ask Tom…he knows it better than the back of his hand.
