Johnson Lake is a small lake in Marquette County with one public launch and the kind of low-key, locals-know-it feel that keeps it off most radar. Reviews suggest solid warm-water fishing — crappie, largemouth and smallmouth bass, northern pike, and bluegill all show up regularly, with multiple anglers noting good-sized crappie and pike. The water is reportedly clear enough for swimming, though at least one visitor has noted leeches near the beach area.
The shoreline has a mix of private homes and cottages, and regulars describe a tight-knit community with spectacular sunsets. Nearby state forest campgrounds at Little Lake and Anderson Lake West give options for overnighting if you're not staying lakeside. Don't expect a developed recreation scene — this is a quiet Upper Peninsula lake where you bring your own entertainment and the fishing does the talking.
