The Missouri is the undisputed winner in the Bozeman area — completely runoff-proof at 3,250 CFS with gin-clear water and temps at 49°F. Heavy BWO activity and a serious caddis emergence in the canyon section are producing outstanding dry fly opportunities daily — the surface game is unbeatable right now but highly technical. Afternoon cloud cover is your best friend for the caddis hatch. Low, clear flows mean eagle-eyed, skittish trout that will pick apart a bad drift. Drop to 5X-6X tippet, long leaders (12+ feet), keep your profile low, and make your first cast count. Subsurface: sowbugs, scuds, and small pheasant tails are doing the heavy lifting on shallow flats and scum lines. Trail an unweighted Pheasant Tail #18-22 or small soft hackle behind a dry. Streamers currently taking a back seat to the incredible dry fly action. As every freestone in the region blows out, the Missouri is getting significantly more crowded — expect heavy company, especially weekends between Holter Dam and Craig. Still the most consistent fishing in southwest Montana by a wide margin and will stay that way through the entire runoff period. The river could use more precipitation to fill out the banks, but current conditions are prime for anyone willing to put in the technical work.Flow10,800 CFS

The Yellowstone has surged past 10,800 CFS at Livingston — nearly 3x the ideal 2,000-4,000 CFS float window and still climbing as temps in the 80s drive aggressive snowmelt. River is dangerously high and completely blown out. Not recommended for fishing or floating under any circumstances. Yellowstone Angler reported the Mother's Day caddis ran for nearly 3 weeks this year — 'one of the better caddis hatches we've seen in years' — but that legendary window is now completely over. Flows forecast to continue rising through the week with no relief. Grey Bear access closed for parking lot construction; 89 Bridge open but requires alternate routing — drive past on I-90, exit at Mission Creek, U-turn and drive west, exit at 89 North. Paradise Valley spring creeks (DePuy's, Armstrong's, Nelson's) are the premium fallback — crystal clear water, daily baetis and caddis hatches, demand very high with the main river blown out. Book rod fees well in advance. Don't expect fishable conditions on the Yellowstone until mid-to-late June at the earliest. Contact Yellowstone Angler (406-222-7130) for real-time flow and clarity updates.Flow2,200 CFS

Gallatin at ~2,200 CFS near Gallatin Gateway — over 5x the ideal 200-400 CFS wading range and still climbing as temps in the 80s drive aggressive snowmelt. The river is cold, chalky, and in full runoff mode. Wading is dangerous in the main channel — not recommended. Fish are turning almost exclusively on small caddis nymphs and rubberlegs in the few soft-water pockets that exist. If you must fish, target above Taylor Fork where clarity is marginally better and work slower side channels with heavy nymphs (Pat's Rubberlegs #8-10 with extra split shot). Dry fly fishing is completely off the table. The Gallatin will be in runoff mode for several more weeks — once flows start dropping, nymphing picks up quickly even with just a foot of visibility. Mid-to-late June is the earliest realistic clearing date when salmonfly season begins. Most anglers should shift to the Missouri or Paradise Valley spring creeks for fishable water right now.Flow1,450 CFS

Madison at ~1,450 CFS near Cameron — well above the ideal 800-1,200 CFS window and rising as snowmelt runoff accelerates with temps in the 70s-80s. The seasonal closure that was in effect through May 16 is lifting — verify current open/closed status with Montana FWP before heading out. The Upper Madison near Hebgen and Quake Lake remains the most reliable freestone water in the region with the best clarity and is fishable right now. Mother's Day caddis still producing on the Lower Madison — caddis pupae and emerging adults driving splashy rises in seams and along banks; Jake's Caddis #14-16, Corn Fed Caddis #14-16, and Loop Wing Caddis #14-16 are the top patterns for rising fish. Best surface action 11am-3pm as air temps climb; evening brings another window when sun gets off the water. Morning strategy: swing sculpins and streamers through deeper pools before the hatch fires. Nymphing remains the primary game with Pat's Rubberlegs #6-10 and Zurdle #8-12 in deeper runs. Salmonfly hatch building and will fire in the coming weeks as water temps push into the low 50s consistently. The lower river is transitioning into full runoff mode — fish the upper sections for the most reliable experience.🎣 TACTICS RIGHT NOWDry FlyJake's Caddis #14-16Corn Fed Caddis #14-16Loop Wing Caddis #14-16X Caddis #14-16Elk Hair Caddis #14-16Super Pupa Caddis #12Parachute Adams #12-22CDC Emerger #18-22Para BWO #16-20RS2 Emerger #18-22Juju Baetis #18-22Griffith's Gnat #16-20

11am-3pm across all fishable rivers. The Missouri River is the undisputed standout — gin-clear at 3,250 CFS and 49°F with heavy BWOs, caddis emergence, and outstanding dry fly opportunities daily (especially under cloud cover). The Upper Madison near Hebgen/Quake is the only viable freestone option — the seasonal closure that was in effect through May 16 is lifting; verify with FWP before heading out. Mother's Day caddis still producing on the Lower Madison with Jake's Caddis and Corn Fed Caddis the top patterns. The Yellowstone is dangerously blown out at ~10,800 CFS — do not fish or float. The Gallatin is blown out at ~2,200 CFS — skip it entirely. Paradise Valley spring creeks (DePuy's, Armstrong's, Nelson's) are the premium alternative for crystal-clear technical dry fly fishing with daily baetis and caddis hatches. Nymphing is the primary technique on freestones. Wind remains the biggest daily variable. FORECASTPeak runoff is hammering all freestones. The Yellowstone at ~10,800 CFS is nearly 3x its ideal float window and still climbing — don't expect fishable conditions until mid-to-late June at the earliest. The Gallatin at ~2,200 CFS is deep in runoff with no relief for weeks. The Madison at ~1,450 CFS is above its ideal window with the lower sections in full runoff; the Upper near Hebgen/Quake is the last freestone holdout with fishable clarity. The seasonal closure through May 16 is lifting — salmonfly hatch will fire when water temps sustain in the low 50s, likely late May to early June. The Missouri River at 3,250 CFS is the undisputed champion — completely runoff-proof, gin-clear, 49°F, and fishing at its best with heavy BWO and caddis hatches. Paradise Valley spring creeks are fishing lights-out with daily baetis and caddis — the premium fallback for clear water technical fishing while freestones are off. Spring runoff timeline: Firehole may clear by May 20-25; main rivers mid-to-late June; Lamar system and small mountain streams June 20-25.Temps in the 80s are driving aggressive snowmelt across all mountain ranges — the hardest push of the season. The Yellowstone and Gallatin are surging with flows forecast to continue rising through the week. No relief in sight until sustained warm weather melts out the remaining snowpack, likely mid-June at the earliest. Cold snaps can briefly stall runoff and open short fishing windows on freestones — watch the forecast closely but don't count on it this week. The Missouri will fish strong through the entire runoff period and into summer — it's the safe bet for the next 4-6 weeks. Afternoon thunderstorms becoming more frequent — plan to be off exposed water by early afternoon. Wind remains the biggest daily variable on all waters.
Overview
Bozeman sits at the center of some of the best trout fishing in the American West. Within a day's drive you can access over 500 miles of floatable water and countless miles of wadeable streams. The Gallatin, Madison, and Yellowstone Rivers all flow within 30 minutes of town, while the Missouri River tailwater is about two hours away.
The diversity of water is the real draw: you can fish the technical tailwater of the Missouri one day, the pocket water of Gallatin Canyon the next, and finish the week floating the Yellowstone through Paradise Valley. Rainbow, brown, and native Yellowstone cutthroat trout inhabit these waters in healthy populations.
Drive Times from Bozeman:
| Destination | Distance | Time |
|---|
| Gallatin Canyon (Big Sky area) | 45 miles | 1 hour |
| Livingston (Yellowstone River) | 26 miles | 25 min |
| Ennis (Madison River) | 65 miles | 1 hr 15 min |
| Craig (Missouri River) | 115 miles | 2 hours |
| West Yellowstone | 90 miles | 1 hr 30 min |
Seasons and Runoff
Montana rivers follow snowmelt patterns from the Absaroka, Gallatin, and Madison mountain ranges:
| Season | Timing | Conditions | Best Bet |
|---|
| Winter | Dec-Mar | Cold but fishable, midges hatch daily, light crowds | Lower Madison, Gallatin Canyon, Missouri |
| Spring | Apr-May | Pre-runoff fishing can be excellent, BWOs hatch | Tailwaters, lower sections |
| Runoff | May-Jun | Peak flows, freestones go off-color | Missouri River (tailwater stays clear) |
| Summer | Jul-Aug | Prime time - prolific hatches, rivers clear | Everything fishable, best variety |
| Fall | Sep-Oct | Brown trout aggressive pre-spawn, fewer crowds | Yellowstone, Madison, streamers effective |
Key timing notes:
- June and July are prime fishing months with prolific hatches on all major rivers
- Freestone rivers (Gallatin, Yellowstone) typically clear and fish well starting mid-June
- The Missouri River fishes year-round due to dam-controlled tailwater flows
- Salmonfly hatches on the Madison and Yellowstone begin mid-June and migrate upstream through July
- Fall brown trout become aggressive in October during pre-spawn
Water Temperature Considerations:
Summer water temps can reach the mid-70s°F on freestone rivers during hot spells. Montana FWP issues "Hoot Owl" restrictions (no fishing 2pm-midnight) when temps exceed 73°F for three consecutive days. This typically affects the Madison and Yellowstone in late July/August. Check current restrictions before fishing during hot weather.
Major Rivers
Gallatin River
Drive time from Bozeman: 45 minutes to 1 hour to prime water in Gallatin Canyon along Highway 191.
The Gallatin is the local favorite - a blue ribbon river offering quality fishing from its headwaters in Yellowstone National Park to the Missouri River headwaters near Three Forks. The river changes character dramatically over its 120-mile course, offering everything from meadow water to rocky canyon pocket water to open prairie runs.
Flow Windows (Gallatin Gateway):
| CFS | Conditions |
|---|
| 200-400 | Ideal wading - good clarity, accessible fishing |
| 400-800 | Higher but fishable, some wading limitations |
| 800-1,500 | Float access for wade fishing only (no boat fishing allowed above East Gallatin confluence) |
| 1,500+ | High water, whitewater rafting season |
Water Temperature: Summer temps typically reach 55-65°F. The Gallatin rarely hits Hoot Owl restrictions due to its higher elevation and canyon shade.
Character: The Gallatin is smaller and more technical than neighboring rivers. It's primarily wade-fishing water with shallow riffles leading to long runs and deep pools. Large brown and rainbow trout hold in undercut banks and behind boulders.
Whitewater: The Gallatin Canyon offers some of the best whitewater in the Yellowstone-Teton area. In June when snowmelt is released, the "Mad Mile" section runs Class IV with continuous challenging rapids. Later in summer the river mellows to Class II-III.
Specific Access Points (Highway 191, south to north):
| Access Point | Mile Marker | Notes |
|---|
| Yellowstone Park Boundary | MM 0 | Park permit required upstream |
| Bacon Rind Creek Trail | MM 22 | Short dirt road, good backcountry access |
| Taylor Fork | MM 30-32 | Multiple pullouts, surprisingly light pressure |
| Portal Creek | MM 40 | Popular float put-in for rafters |
| Moose Creek Flat | MM 43 | Good parking, easy river access |
| Greek Creek | MM 48 | USFS campground, river access |
| Storm Castle | MM 52 | Pullout access |
| Gallatin Gateway | - | Lower river access, gauge location |
Lower Gallatin FWP Access Sites (by River Mile):
- Kirk Wildlife Refuge (RM 46)
- Axtell Bridge (RM 37)
- Shed's Bridge (RM 33)
- Cameron Bridge (RM 27)
- Gallatin Forks (RM 13) - Float fishing from boat begins here
Important: Fishing from a boat is NOT allowed from the headwaters to the East Gallatin confluence. You can use a boat for access to wade-fish, but must step out to cast. Float fishing from a boat is allowed only below Gallatin Forks Access Site, 12 miles upstream from Three Forks.
Key flies: Stonefly nymphs (Pat's Rubber Legs in olive and brown, sizes 6-10), Pheasant Tails (14-18), Prince Nymphs (12-16), Elk Hair Caddis (14-18), Parachute Adams (14-18)
Madison River
Often called the "50-Mile Riffle," the Madison offers 130 miles of trout-bearing water from Yellowstone Park to Three Forks. Known for its salmonfly hatch and outstanding hopper fishing, the Madison provides the most consistent fishing of any river in the Bozeman area.
Drive time from Bozeman: 1 hour 15 minutes to Ennis; 1.5 hours to West Yellowstone.
Flow Windows (Madison near Cameron):
| CFS | Conditions |
|---|
| 800-1,200 | Ideal - excellent wading and float fishing |
| 1,200-1,800 | Good fishing, faster current |
| 1,800-2,500 | High but manageable for experienced anglers |
| 2,500+ | Runoff conditions, fishing difficult |
Water Temperature: Summer temps can reach 73-80°F, especially on the lower river. Hoot Owl restrictions are common in late July/August. The Upper Madison below Quake Lake stays cooler.
Sections:
Upper Madison (Inside Yellowstone Park to Quake Lake)
- Meadow sections with undercut banks
- Excellent PMD and hopper fishing
- Yellowstone Park permit required for sections inside the park
Upper Madison (Quake Lake to Ennis Lake) - The "50-Mile Riffle"
- Continuous pocket water and riffles
- Home to the legendary PMD hatches in late June through July
- Fish counts roughly 4,500 catchable trout per mile above Varney Bridge
- Best dry fly fishing on the river
Lower Madison (Below Ennis Lake)
- Dam-controlled tailwater
- Mother's Day caddis hatch begins late April
- Excellent winter fishing with midges and BWOs
- Fish counts drop to roughly 3,000 per mile below Varney Bridge
Bear Trap Canyon
- Rugged, remote stretch flowing out of Ennis Lake
- Steep, jagged canyon walls
- Technical wading, outstanding fishing - experts only
Float Sections and Distances:
| Section | Distance | Float Time | Notes |
|---|
| Lyons Bridge to Windy Point | 6.2 miles | 3-4 hours | Upper, fast water |
| Lyons Bridge to McAtee Bridge | 15.3 miles | Full day | Long float, bring lunch |
| McAtee Bridge to Varney Bridge | ~9 miles | Full day | Most popular section |
| Varney Bridge to Ennis | ~10 miles | Full day | Spring Creek Channel splits off 1 mile below Varney - portage required at low flows |
Access Points:
- Lyons Bridge FAS: Upper river put-in
- McAtee Bridge FAS: 19 miles south of Ennis
- Storey Ditch: 2 miles below McAtee, alternative put-in
- Varney Bridge FAS: 10 miles south of Ennis, primary mid-river access
- Eight Mile FAS: Between Varney and Ennis, west bank
- Burnt Tree FAS: Between Varney and Ennis, west bank
- Ennis FAS: Town take-out
Hazard: Below Varney Bridge, the Spring Creek Channel splits from the main river. This channel has a diversion dam that requires portage at lower flows. Better suited for rafts, kayaks, or canoes. Avoid the left channel above Ennis - diversion dam requires portage.
Major Hatches:
| Hatch | Timing | Flies |
|---|
| Mother's Day Caddis | Late Apr-May | Sizes 14-16, Lower Madison |
| March Browns | Late Apr-mid May | Sizes 10-14 |
| Salmonflies | Mid-Jun, migrating upstream | Sizes 4-8 |
| Golden Stoneflies | Late Jun-Jul | Sizes 6-10 |
| PMDs | Late Jun-Jul | Sizes 14-16, Upper Madison |
| Flying Ants | Late Jul-Aug | Sizes 12-14, golden-cinnamon color |
| Hoppers | Jul-Sep | Sizes 8-12 |
| Fall BWOs | Sep-Oct | Sizes 16-22 |
Key flies:
- Dry: Parachute Adams, Purple Haze, Missing Link Caddis, Rio's Juicy Hopper, CFO Ant Black, Yellow Thunder Thighs
- Nymph: Pat's Rubber Legs, Pheasant Tail, Prince Nymph, Zebra Midge, Rainbow Warrior, Perdigon
- Streamer: Black Dungeon, Olive Screamer, Olive Peanut Envy, Sparkle Minnow
Tip: Streamers are effective for big trout on the Madison. Swing them through deeper runs for trophy browns and rainbows.
Yellowstone River
The Yellowstone is the longest undammed river in the contiguous 48 states and one of the finest freestone trout rivers in the world. From its headwaters in Yellowstone National Park, through the roaring rapids of Yankee Jim Canyon, and into Paradise Valley, the Yellowstone offers a lifetime of fly fishing.
Drive time from Bozeman: 25 minutes to Livingston; 1 hour 20 minutes to Gardiner.
Flow Windows (Yellowstone near Livingston):
| CFS | Conditions |
|---|
| 2,000-4,000 | Ideal float fishing - good current, manageable rapids |
| 4,000-6,000 | Higher but floatable, faster action |
| 6,000-10,000 | High water, more technical floating |
| 10,000+ | Runoff - dangerous, unfishable |
Water Temperature: Summer temps can reach 68-75°F in Paradise Valley. Hoot Owl restrictions possible in late July/August during heat waves.
Trout Species:
- Yellowstone Cutthroat: High numbers in the upper section near Yankee Jim Canyon. Average 8-16 inches with occasional fish to 20 inches. Cutthroats comprise 1/3 to 1/2 the population upstream from Carbella Access but fade downstream.
- Brown Trout: Paradise Valley floats can produce very large browns - 10-pounders still exist. The stretch from Livingston downstream to Columbus holds larger than average browns, typically 16-20 inches with fish to 24 inches possible.
- Rainbow Trout: Good numbers throughout, especially in the Livingston "town stretch" which has some of the highest rainbow counts on the entire river.
Float Sections and Access (Paradise Valley, upstream to downstream):
| Section | Distance | Notes |
|---|
| Gardiner to Yankee Jim Canyon | Variable | Technical Class III, cutthroat water |
| Grey Owl to Mallard's Rest | ~8 miles | "The Bird Float" - most scenic, mellow, great fishing |
| Mallard's Rest to Pine Creek | ~5 miles | Good mix of water types |
| Pine Creek to Carter's Bridge | ~6 miles | Best at lower flows |
| Carter's to Mayor's Landing | ~7 miles | Good browns and rainbows |
Key Access Points:
| Access Site | Location | Notes |
|---|
| Grey Owl FAS | South of Emigrant | Upper Paradise Valley put-in |
| Mallard's Rest FAS | MM 42, 12 miles south of Livingston | Boat ramp, 13 campsites. Note: Entrance relocated a few hundred yards north after 2022 flood damage |
| Pine Creek FAS | Below Mallard's | Good ramp, plenty of parking |
| Carter's Bridge FAS | North of Pine Creek | Rocky beach launch, good wade access |
| Mayor's Landing | Near Livingston | Town stretch access |
Livingston "Town Stretch":
- Highest rainbow trout counts on the entire Yellowstone
- Varied habitat with spring creek influences
- Has produced several 15-pound browns in recent years
- Excellent fall streamer fishing
- Walk from downtown to fish
Major Hatches:
- Salmonfly (mid-late June): The signature hatch. Occurs shortly after runoff when trout are hungry post-spawn.
- Caddis, Mayflies, Stoneflies (June-September): Dense hatches throughout summer
- Hoppers (July-September): Some of the largest brown trout come to the surface for hoppers along the banks
- Streamers (October): Fall streamer fishing through Livingston brings some seriously large fish. Browns become aggressive pre-spawn.
Access: Good public access at numerous FWP fishing access sites throughout Paradise Valley and around Livingston.
Missouri River
The Missouri River tailwater below Holter Dam near Craig, Montana is one of the most productive wild trout fisheries in the Northern Rockies. Often called "the world's largest spring creek," this 35-mile section holds 7,000-8,000 trout per mile averaging 15-17 inches, with many fish reaching 20+ inches.
Drive time from Bozeman: 2 hours via I-90 west to Three Forks, then Highway 287 north through Helena to I-15, exit 234 for Craig.
Alternative airports: Helena (HLN) is 45 minutes from Craig; Great Falls is 45 minutes north.
Flow Windows (Missouri below Holter Dam):
| CFS | Conditions |
|---|
| 3,500-5,000 | Ideal - excellent clarity, consistent hatches |
| 5,000-7,000 | Higher but fishable |
| 7,000+ | Faster current, more technical |
Water Temperature: Tailwater temps stay consistent year-round, typically 45-55°F. No Hoot Owl restrictions. Fishable in winter when other rivers are frozen.
Float Sections and Distances:
| Section | Distance | Notes |
|---|
| Holter Dam to Wolf Creek Bridge | 2.3 miles | Short float, highest fish density |
| Wolf Creek Bridge to Craig | 5.5 miles | Classic upper section |
| Craig to Stickney Creek | 3.7 miles | Entering the canyon |
| Stickney Creek to Spite Hill | 0.7 miles | Short connector |
| Spite Hill to Dearborn | 1.5 miles | Canyon water |
| Dearborn to Cascade | ~20 miles | Lower section, Tower Rock, Lone Pine rapids (Class II) |
Sections:
Upper Section (Holter Dam to Craig, ~8 miles)
- Highest fish concentrations
- Nearly 100 yards wide in places
- Most accessible, most popular
Canyon Section (Below Craig)
- Huge limestone cliffs
- Dearborn River confluence
- More defined structure with sharper banks and mid-river boulders
- Ends at Tower Rock near Lone Pine rapids
Lower Section (Tower Rock to Cascade)
- Broadens onto Great Plains
- Big sky views, abundant wildlife
- Exceptional dry fly water
"Land of Giants" (Below Hauser Dam)
- 20 minutes north of Helena
- Mostly rainbow fishery averaging 18-22 inches
- Less pressure than Craig section
Major Hatches:
| Hatch | Timing | Notes |
|---|
| Midges | Year-round | The winter staple |
| BWOs | Spring & Fall | Sizes 16-22 |
| PMDs | June-July | Prime time |
| Caddis | June-August | Good dry fly action |
| Tricos | Late Jul-early Sep | Incredible hatches, technical fishing |
Key flies: Trico patterns (18-22), PMD emergers (14-18), Baetis comparaduns (18-22), Zebra Midges (18-24), CDC dries, small Sparkle Duns, Sparkle Pupa
Best Timing: April through November are the best months. May, June, and early July are prime time. The Missouri fishes well year-round - you can fish in winter with good success when other rivers are frozen.
Practical Notes:
- Most anglers fish from drift boats with guides
- Shuttle services available in Craig (book ahead for summer weekends)
- Craig has lodging, food, fly shops, and the famous Craig Bar
- Summer weekends are crowded between Holter Dam and Cascade - keep well back from other boats

Beginner-Friendly Options
If you're new to Montana fly fishing:
For wade fishing:
- Gallatin River along Highway 191: Easy pullout access, smaller water, clear wading paths. The pocket water is forgiving for beginning casters. Start near Greek Creek or Moose Creek Flat.
- Madison River near Varney Bridge: Consistent fishing, good roadside access, classic dry fly water
- Yellowstone River town stretch (Livingston): Good access points, varied water types to learn on
For float fishing:
- Yellowstone River Paradise Valley: Wide river, Class I-II water, forgiving for drifting. Many outfitters run beginner-friendly trips. The "Bird Float" (Grey Owl to Mallard's Rest) is mellow and scenic.
- Missouri River guided trips: Guides position you over feeding fish. Technical fishing but guides do the hard work of rowing and spotting fish.
Guided Trips:
For first-time visitors, a guided trip is worth the investment. Local guides know current hatch activity, optimal flows, and productive water.

Safety and Hazards
Cold Water
All Montana rivers run cold, even in summer. Tailwaters like the Missouri stay in the 45-55°F range year-round. Freestones warm to 55-70°F in summer but can be dangerously cold during runoff. Hypothermia is possible with extended immersion. Bring waders and layers.
Spring Runoff
Late May through mid-June brings peak flows. Freestone rivers can be dangerous - cold, fast, debris-laden. The Missouri remains clear due to dam control. Check gauges before any trip during runoff season.
Whitewater
- Gallatin Canyon Mad Mile: Class IV during peak flows. Experienced paddlers only.
- Yankee Jim Canyon (Yellowstone): Class III rapids, technical rowing required.
- Bear Trap Canyon (Madison): Remote, rugged, experts only.
- Missouri Lone Pine Rapids: Class II near Cascade, manageable for intermediate floaters.
Weather
Afternoon thunderstorms are common in summer. Lightning poses a real danger on open water. Plan to be off the river by early afternoon during storm season. Weather can change quickly in mountain valleys.
Wildlife
Grizzly bears inhabit the Greater Yellowstone Ecosystem. Carry bear spray, especially when fishing backcountry or in Yellowstone Park. Make noise, store food properly. Black bears, moose, and mountain lions also present.
Heat and Hoot Owl Restrictions
During hot spells (late July-August), water temps can exceed 73°F, stressing trout. Montana FWP issues Hoot Owl restrictions closing fishing from 2pm-midnight. Check current restrictions at Montana FWP website before fishing during hot weather.
