Triangle Lake Fishing in Madison County, Montana

• Overview

  Triangle Lake stands in Madison County, Montana. It sits at 9,088 feet above sea level. You can fish the entire water from one spot if you pick it well. On size it sits at the modest end of our Madison County list. Start from Whitehall, 24 miles down the road. Three Forks lies 34 miles off, Big Sky another 36 miles. No boundary runs near, so the county rules hold throughout.

• Where to Fish on Triangle Lake

  We hold no depth figure for this one. A natural lake fishes on cover, and cover here means weed and timber. Weed, then depth: that is the order to fish a water of this kind. Public occurrence data for Madison County names rainbow trout, brown trout and mountain whitefish. Species recorded across the county may be limited to a few waters. On Triangle Lake the obvious spot is not always the productive one.

• Seasonal Patterns

  Typical July readings run about 51°F; by January the average is down near 17°F. Fishing here follows the temperature more than the calendar. Hard water holds through the cold months, breaking up near late May. The season between ice runs from about late May to early November. The open run goes from the thaw to the freeze, and April through October covers most of it. Keep it in mind when planning a trip to Triangle Lake.

• Tackle & Baits

  The access position is unclear from public sources. Formal access is not mapped, so the last stretch is likely on foot. For the trout, small spinners and a box of nymphs cover both approaches. Where the road in crosses private land, ask first. Keep proof of licence with you rather than in the car. Oval Lake at 0.2 miles is the sensible second choice. Nothing here settles the position at Triangle Lake for certain.
