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.
Flathead system browns turn aggressive as fall cooldown sets in
The Flathead system gauge (USGS 12372000) logged 7,160 cfs and 62°F Friday evening, a reading that lines up with the fall temperature slide pushing trout out of their summer holding patterns. Field & Stream's fall live-bait roundup, timed to this exact window, recommends a bottom-bouncing minnow rig on a barrel swivel to keep bait in the strike zone as big browns turn more aggressive with the cooldown — a technique worth carrying into Flathead and Bitterroot water right now.
Big Hole River reopens as Montana rivers head into fall closures
Montana FWP lifted the angling closure on Big Hole River Section 5 this week, citing improved flows after weekend rain — good news for anglers on the stretch between the Tony Schoonen (Notch) fishing access site and the Beaverhead River confluence. Section 1, running from the Saginaw Bridge on Skinner Meadows Road to that same confluence, stays closed for now. MT FWP Fishing News also flags October 1 as the start of seasonal spawning closures on some Montana rivers, a date worth building trips around this week. Farther north, FWP lifted hoot-owl afternoon fishing restrictions on the Smith and Sun Rivers in late August as water temperatures cooled below the threshold that triggers them, an early marker of the fall transition now working its way across the state's trout water.
Big Hole River reopens as Montana rivers cool and restrictions lift
Montana Fish, Wildlife & Parks lifted the angling closure on Section 5 of the Big Hole River this week, from the Tony Schoonen Fishing Access Site down to the Beaverhead River confluence, after weekend rain improved flows enough to meet the agency's threshold, per MT FWP Fishing News. Section 1 of the Big Hole, upstream near Saginaw Bridge, stays closed. The same rain and cooling trend eased hoot-owl restrictions elsewhere in the state: FWP lifted the afternoon closures on the Smith and Sun Rivers on Aug. 28 as water temperatures moderated, and this week cleared restrictions on stretches of the upper Clark Fork (from the Warm Springs/Silver Bow Creek confluence to the Blackfoot River) and the lower Bitterroot (Veteran's Bridge in Hamilton to the Clark Fork confluence). FWP also flagged an unusual sighting on the Missouri system this week: an angler found freshwater jellyfish near Canyon Ferry Reservoir, a rare but harmless species that occasionally turns up in warm, still water late in the season.
Flathead and Bitterroot waters shift toward fall's low-light bite
Water across the Flathead Lake and Bitterroot system is entering the early-fall transition, the point in the season when cooling surface temperatures start pushing feeding activity toward the margins of the day. Field & Stream's latest gear roundup notes that brown trout shift into peak activity right around dusk and dawn as the season turns, a timing pattern worth building a trip around on this stretch of water. This week's waxing gibbous moon keeps a good amount of light in the sky overnight, which tends to spread that low-light window a little wider rather than concentrating it right at sunset.
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.
