Can't think of the names right off, but there are a couple near Fremont, central WI. We live near there and have been by them on our boat. A couple are on Partridge lake, another right on the wolf river.
There's also a great county park on the east side of lake Petenwell, part of the Wisconsin river, north of the Dells.
Near Madison look into Lake Farm county park or Bradley county park just south of Madison in McFarland.
Start looking around the Eagle River area and you'll find a number of them.
