• Where to Fish on Hidden Lake

  There is no recorded depth, so work from what you can see. A natural lake fishes on cover, and cover here means weed and timber. The productive water is a rod length or two out, not a hundred. Records held for Custer County cover rainbow trout, cutthroat trout and Chinook salmon. Several of these carry legal protection or closed seasons; the rulebook comes before the rod. Take Hidden Lake a stretch at a time.

• Seasonal Patterns

  Temperature averages peak at 51°F in July and bottom out at 16°F in December. Four clear seasons, with a proper winter at one end. The freeze runs deep into the year, with break-up near late May. Break-up sits around late May on average, with the water closing again about early November. From the thaw to midsummer the fishing improves week by week. On Hidden Lake the same rules apply, with local timing.

• Tackle & Baits

  Nothing in our records says who may fish here. Records list it as a natural water body rather than an impoundment. No made access appears within a short radius, so plan to park on a verge and walk. Light line and small metal for the trout; a fly rod earns its place on calm evenings. A landowner's word beats anything printed elsewhere. Fishing rules and camping rules are set separately here. Should this one be busy, Profile Lake is 1.6 miles off. Treat Hidden Lake as unsettled until someone local tells you otherwise.
