Big Hole River reopens as Montana's fall spawning closures take hold
Montana Fish, Wildlife & Parks reports that the angling closure on Section 5 of the Big Hole River has been lifted after rain over the weekend improved flows, per MT FWP Fishing News. Section 5 runs from the Tony Schoonen Fishing Access Site (Notch) downstream to the confluence with the Beaverhead River — water that feeds into the Missouri's headwaters system by way of the Jefferson. Section 1, farther upstream, stays closed. The same MT FWP release flagged that spawning closures on several Montana rivers took effect October 1, a seasonal marker worth knowing for anyone working the Missouri drainage right now. Separately, MT FWP notes six of the state's seventeen aquatic invasive species inspection stations remain open through October in high-risk travel corridors, so boat and trailer checks are still part of the routine this month for anglers moving between waters.
Big Hole River reopens as rain lifts Montana flows
Rain over the weekend eased river levels enough for Montana Fish, Wildlife & Parks to lift the angling closure on Section 5 of the Big Hole River, from the Tony Schoonen access site down to the Beaverhead confluence, per MT FWP Fishing News. Section 1 stays closed. Regional USGS gauges show water temperatures spanning 45°F to 58°F and flows between 224 and 1160 cfs this morning, a wide spread that reflects the mix of smaller feeder streams and larger stems typical of the Yellowstone and Missouri headwaters country this time of year. MT FWP also flagged that spawning closures on some rivers begin October 1, so anglers should confirm water-specific rules before fishing moving water this week. Separately, Outdoor Hub reports Montana is considering removing daily limits on northern pike, rainbow trout, and smallmouth bass at Flathead Lake under the proposed 2027-2028 regulations, not yet in effect.
Flathead system eases into fall as Montana floats bigger limits
The Flathead River near Columbia Falls (USGS gauge 12372000) read 60°F with flow holding at 7,210 cfs in this morning's pre-dawn check, a steady fall-transition signature for the Flathead Lake and Bitterroot drainages. The bigger regional story this week isn't a bite report, it's regulatory: Montana Fish, Wildlife & Parks has proposed removing the daily limits on northern pike, rainbow trout, and smallmouth bass in Flathead Lake for the 2027-28 season, Outdoor Hub reports, reflecting how thick those populations have grown in the lake.
Big Hole River Reopens as Fall Spawning Closures Take Hold
Montana Fish, Wildlife & Parks lifted the angling closure on Section 5 of the Big Hole River, from the Tony Schoonen Fishing Access Site down to its confluence with the Beaverhead River, after weekend rain pushed flows back up, per MT FWP Fishing News. The Section 1 closure, covering water from the Saginaw Bridge on Skinner Meadows Road downstream, stays in effect. FWP also notes that spawning closures on some rivers begin October 1, a routine fall measure across the upper Missouri drainage that anglers in the Yellowstone and Missouri systems should expect to see rolled out stretch by stretch this month.
Flathead Lake Limits Could Loosen as Fall Fishing Settles In
Montana Fish, Wildlife & Parks is considering removing daily catch limits on northern pike, rainbow trout and smallmouth bass at Flathead Lake, according to Outdoor Hub's rundown of the agency's proposed 2027-28 regulations. If adopted, anglers could keep unlimited numbers of all three species there, a notable loosening from current catch limits on those species. The proposal is still working through the regulatory process and is not in effect this season, so standard limits still apply on the water right now. Beyond that, early October in the Flathead and Bitterroot drainages is squarely fall-transition territory, with fish shifting off summer haunts as days shorten and water cools.
Big Hole Section 5 reopens as FWP lifts angling closure
FWP lifted the angling closure on Section 5 of the Big Hole River, which runs from Tony Schoonen Fishing Access Site (Notch) to the Beaverhead River confluence, after weekend rain improved flows, according to MT FWP Fishing News. Section 1 stays closed, so check the section boundaries before you go. The same release says spawning closures on some rivers begin October 1. Montana waters remain invasive mussel free, but six of seventeen AIS inspection stations are still running through October in high-risk corridors, and anglers with watercraft must stop at every station they pass.
Brown and brook trout staging as western Montana cools into fall
Early October is the cool-water turn across western Montana, and it is the shift that matters most for trout right now. Brown and brook trout typically start moving off summer holding water toward gravel and cold tributary inflows as the fall spawn approaches, so fish that were spread out through August become easier to find in predictable places. Plan around those staging areas rather than open water, and expect the strongest bite in the warmest part of the day, when surface water has had a chance to rise a little.
Fall Closures Arrive on Montana Rivers as Flows Rebound
Montana Fish, Wildlife & Parks lifted the angling closure on Section 5 of the Big Hole River this week, citing improved flows after weekend rain, per MT FWP Fishing News. The timing lines up with a broader shift: spawning closures on several Montana rivers begin today, October 1, so anglers should confirm current regulations before fishing water they haven't checked recently. Aquatic invasive species inspection stations remain active at six of the state's seventeen sites through the high-risk fall corridor, per MT FWP Fishing News, so boaters should plan for a stop. Elsewhere, Field & Stream flagged a Montana angler's catch of a smallmouth bass measuring nearly 23 inches on a homemade glide bait. The fish would have challenged the IGFA all-tackle length record had it been measured on a certified board, a reminder that fall smallmouth are already feeding aggressively around the state.
Big Hole reopens as Montana's fall closures take hold
Montana Fish, Wildlife & Parks lifted the angling closure on Big Hole River Section 5 this week, covering the water from the Tony Schoonen Fishing Access Site downstream to the Beaverhead River confluence, after weekend rain pushed flows back up, according to MT FWP Fishing News. Section 1, from Saginaw Bridge on Skinner Meadows Road to the same confluence, stays closed. The reopening lands right before Montana's shift into fall regulations: spawning closures on select rivers begin October 1, per the same release, so anglers working tributaries that feed the Missouri headwaters should check current closure maps before launching this week. Aquatic invasive species inspection stations remain active too, with six of seventeen still staffed through October in high-risk corridors, and any boater trailering into Missouri or Yellowstone drainage waters is required to stop.
Fall Cooldown Settles Over Flathead Lake and the Bitterroot
Late September marks Montana's turn into fall fishing conditions on Flathead Lake and the Bitterroot River, as the summer thermocline breaks down and water cools steadily through October. That shift typically pulls baitfish tight to structure and edges, and resident trout tend to respond with steadier feeding through the day rather than clustering around the narrow low-light windows that dominate peak summer heat.
Big Hole River reopens as Montana's fall closures approach
Montana Fish, Wildlife & Parks lifted the angling closure on Section 5 of the Big Hole River this week after weekend rain improved flows, per MT FWP Fishing News, welcome news as several state rivers head into the spawning-closure season that begins October 1. The Big Hole's Section 1 closure, from Saginaw Bridge to the confluence, remains in place. In Livingston, FWP has scheduled an October 1 public meeting to discuss removing illegally introduced bass from Sacajawea Lagoon, part of the agency's ongoing push to protect native fisheries in southwest Montana waters.
Big Hole River reopens as Yellowstone country shifts toward fall
Montana FWP lifted the closure on the Big Hole River's Section 5, from the Tony Schoonen (Notch) fishing access to the confluence with the Beaverhead, after weekend rain improved flows; the upstream Section 1 closure stays in place. In Yellowstone country, FWP has scheduled an Oct. 1 public meeting in Livingston to discuss removing illegally introduced bass from Sacajawea Lagoon. Farther north on the Missouri drainage, FWP also flagged a freshwater jellyfish sighting near Canyon Ferry Reservoir, a seasonal oddity anglers working that water should expect to see but not worry about.
Fishing in Montana
Montana is the trout state, full stop. The Madison, Missouri, Bighorn, and Yellowstone are blue-ribbon rivers that anglers travel across the world to fish, and the hatches, the scenery, and the wild fish live up to the reputation. It is not all fly water either: the big reservoirs in the eastern half of the state hold serious walleye, pike, and smallmouth fishing that gets a fraction of the attention.
When to fish Montana
Early spring brings pre-runoff fishing with baetis and skwala hatches before the snowmelt blows the freestone rivers out. Tailwaters like the Missouri and Bighorn stay fishable through runoff, and walleye move shallow on Fort Peck as the water warms.
The rivers clear and drop into shape, and the big hatches roll through: salmonflies, caddis, PMDs, then hoppers along the banks by late summer. On hot stretches, fish early and late, and watch for Montana FWP restrictions on rivers when water temperatures spike.
Brown trout get aggressive ahead of the spawn and streamer fishing comes into its own on the Madison and Yellowstone. The crowds thin out, the cottonwoods turn, and some of the best fishing of the year happens in October.
The Missouri and Bighorn fish all winter with midges and nymphs for anglers willing to bundle up. Ice fishing takes over on the lakes and reservoirs, with perch, walleye, and trout coming through the ice at places like Fort Peck and Canyon Ferry.

Common questions
Do I need a license to fish in Montana?
Yes, most anglers need a Montana fishing license. Montana FWP sells them online, and residents and nonresidents have different options. Check the current FWP regulations before you go, since rules vary by water and season.
What fish can I catch in Montana?
Wild brown and rainbow trout headline the famous rivers, with cutthroat and brook trout in the mountain water. The reservoirs and prairie lakes add walleye, northern pike, smallmouth bass, perch, and lake trout, so there is far more here than fly fishing.
When is the best time to fish Montana?
Summer after runoff clears is prime time on the rivers, with big hatches and stable flows. Fall is the sleeper season: aggressive pre-spawn browns, streamer fishing, and far fewer people on the water.
