That's what we were thinking as well. It HAS to have smallies and skis. H moved up there last summer, so he's put some time in there. He has caught one smaller musky and bunch of pike.
Regarding the DNR site, I don't put much stock into that. Pewaukee Lake is a popular smallie lake here in south/SE WI. Yet their site only lists musky, panfish, largemouth, pike and walleye.
