Marsh Lake Fishing Guide, Park County, Montana

• Overview

  Marsh Lake falls in Park County, part of Montana. The bank is 9,029 feet above sea level. At 3 acres it is the sort of place you fish for an evening rather than a day. Our Park County list holds plenty of bigger water. Red Lodge is the closest place, 32 miles off. It is 83 miles to Billings, the nearest city. The nearest boundary is well away, so one set of rules covers the water.

• Where to Fish on Marsh Lake

  Nothing in our records gives a depth for this one. On a natural lake the weed line and the shelf beyond it do the work. This is a lake, so the margins and the first drop matter most. Open biodiversity records for Park County list rainbow trout, brook trout, california golden trout and brown trout. County records show what lives in the area; the local agency holds the water-by-water list. Marsh Lake gives up its fish to patience rather than distance.

• Seasonal Patterns

  Temperature averages peak at 53°F in July and bottom out at 15°F in January. Spring and autumn carry the fishing; summer and winter test it. The lid arrives early and lasts until roughly mid May. Break-up sits around mid May on average, with the water closing again about early November. May into June fishes hardest, and September gives a second good stretch before the lid returns. It sets the rhythm of the year at Marsh Lake.

• Tackle & Baits

  Public sources are silent on who controls the bank. Nothing is listed nearby for parking or launching a boat. For the trout, small spinners and a box of nymphs cover both approaches. A phone call first saves an afternoon. Close seasons apply to some species and not others. Failing this one, try Wiedy Lake, 0.2 miles away. Treat Marsh Lake as unsettled until someone local tells you otherwise.
