Local Knowledge: Montana Trout Fishing

Based on state fishery reports · always verify before traveling

A regional note specific to this state: the trout water here is dominated by a single high-quality tailwater that runs through a desert canyon, and the state agency manages that tailwater as a trophy fishery, which is why the average fish size is large and the regulations are strict. Montana trout fishing is the most famous in the country, and the only state where an angler can plan a year around the diversity of its freestone rivers and tailwaters. The state has more than 20,000 miles of fishable trout water, including the legendary Madison, the Big Hole, the Bighorn, the Yellowstone, the Missouri, and dozens more. The most famous freestone river is the Madison, a tailwater-like freestone that runs through the high-country plateau of southwestern Montana and produces wild browns and rainbows averaging 16 inches. The state's trout program is administered through the Montana Department of Fish, Wildlife and Parks, and the agency stocks the put-and-take lakes while managing the wild trout water through a combination of slot limits and special regulations. A regular Montana fishing license is required, and the cost is $31 for residents and $106 for non-residents, and the daily limit is 5 trout combined in most waters with special regulations on the wild trout water. The unique regional quirk is that Montana requires a special aquatic invasive species prevention pass for all out-of-state anglers, and the daily limit is 3 trout in the special regulation water of the Big Hole.

About Montana Trout Fishing

Montana's "Big Sky Country" contains thousands of miles of trout streams flowing from the Rocky Mountains. From glacier-fed rivers to spring creeks, the state offers unparalleled variety in pristine settings.

Best Times to Fish in Montana

Spring (March-May)

Spring brings the famous Skwala stonefly hatch starting in March. Runoff affects many rivers in May-June. Focus on the Missouri and other dam-controlled rivers during high water.

Summer (June-August)

Summer is prime season with prolific hatches including PMDs, Caddis, and Golden Stones. Dry fly fishing is at its best. Evening spinner falls can be magical.

Fall (September-November)

Fall offers incredible fishing with spawning brown trout and pre-winter feeding. Streamers become highly effective. The crowds thin after Labor Day.

Winter (December-February)

Winter fishing is productive on tailwaters and spring creeks. The Missouri fishes year-round. Midge and BWO hatches provide surface action on warm days.
