Fishing:
Grass Lake has an abundance of angling opportunities. Largemouth bass, northern pike and tiger musky can be found in the shallow weedy area along the North shore and in the southern arm of the lake. The northeastern basin is deep and harbors nice smallmouth bass and occasional walleye. Panfish tend to be numerous and stunted but are great forage for the other sportfish.
