Montana fishing rules start with your district—not just your fish
Montana uses Western, Central and Eastern Fishing Districts, then adds water-specific exceptions, emergency closures, species permits and special tribal or federal rules. Use this guide to find the rule that actually applies before you cast or keep a fish.
Five Montana rules to know before anything else

Western, Central or Eastern.
Season, daily limit, possession and method.
An exception can replace the district baseline.
Hoot-owl or emergency closures can override the annual guide.
Bull trout and paddlefish need additional attention.
Hoot-owl restrictions can make an otherwise open river illegal after 2 p.m.
2 PM → MIDNIGHT
Montana FWP uses emergency hoot-owl restrictions during hot-water and low-flow conditions. When active, fishing is prohibited every day from 2 p.m. until midnight on the listed reach.

Not every current Montana closure is caused by hot water
Sun River bridge closure
A section beginning 500 feet upstream and ending 500 feet downstream of the Sun River Bridge / Pishkun Road Bridge is closed to all forms of use because of bridge construction.
Current FWP notice lists the emergency closure through November 15, 2026.
Missouri River access closure
FWP currently lists a public-use/access closure downstream of Broadwater Bay Boat Ramp to Black Eagle Dam, including the kayak launch and dock at West Bank Park, because of construction.

Why this page does not pretend one fish table works statewide
District standard
Each Fishing District has its own standard species limits. These are the default rules only when the exact water is not listed as an exception.
Water exception
The regulation book lists individual lakes, reservoirs, rivers and streams that replace the district standard with another season, bag limit, possession limit, size rule or tackle restriction.
Emergency layer
Drought, high temperatures, construction or fish-conservation needs can create temporary restrictions on top of the annual regulation book.
Important 2026 standard-limit patterns worth recognizing
| Species / district example | 2026 standard framework | Why you still check the water |
|---|---|---|
| Western northern pike | Current regulation framework uses liberal harvest; the 2026 Western standard is 15 daily/in possession. | Individual drainages can use even more liberal or different suppression-oriented rules. |
| Central / Eastern crappie | Montana’s statewide fisheries plan identifies a standard 15 daily / 30 possession framework in these districts. | Reservoir-specific exceptions can alter harvest. |
| Sauger / walleye | Current Montana regulation material includes fisheries using a five-fish daily combined framework with sauger sublimits. | Missouri River and major reservoirs frequently have their own management exceptions. |
| Pallid sturgeon | NO TARGETING / NO HARVEST | Endangered species; fish must be released promptly with little or no delay. |
Western Montana and eastern Montana do not use the same live-bait rules
Western District
NO LIVE FISH BAITMontana’s 2026 regulation states that no fish species may be used as live bait in the Western Fishing District.
Central District
RESTRICTED SPECIES / WATERSTen species of fish may be used as bait under the applicable district rules, but collection, possession and transport are regulated.
Eastern District
RESTRICTED SPECIES / WATERSLive-bait use is more available than in western Montana, but it is not permission to move arbitrary live fish between waters.
Do not intentionally target bull trout unless you are in an authorized fishery
Hungry Horse Reservoir / authorized South Fork Flathead reach or Lake Koocanusa?
You need the valid catch card for the specific bull-trout water.
Catch-and-release or limited harvest windows differ by water.
Bull Trout Catch Card facts
The application says the catch card cannot be sent digitally.
Montana paddlefish is a tag-area fishery—not an ordinary bag-limit fishery
FWP divides paddlefish opportunity into four tag areas/fisheries. An angler must choose the applicable area and follow that area’s tag, season, harvest and reporting rules.
Upper Missouri
Fort Peck Dam upstream to Fort Benton.
Season: May 1–June 15.
Harvest tags issued through a lottery. Unsuccessful drawing applicants receive catch-and-release-only privilege under the current system.
Yellowstone River
Designated Yellowstone reaches.
Season: May 15–June 15.
Shared harvest target with the lower Missouri fishery; early closure can be announced.
Lower Missouri
Fort Peck Dam downstream to North Dakota.
Season: May 15–June 15.
One paddlefish per angler under this tag fishery; no catch-and-release for anglers holding this harvest tag.
Fort Peck Dredge Cuts
Archery only.
Season: July 1–August 31.
This is the paddlefish opportunity still inside its scheduled 2026 season on August 12.
Mandatory reporting
- Any paddlefish harvested in Montana must be reported to FWP.
- Reporting rules and deadlines depend on tag color/area.
- Yellowstone and Lower Missouri harvest generally must be reported by 9 p.m. on the day of harvest or before transport from the harvest area.
- If there is no cell service, FWP allows transport of an unreported paddlefish; once communication service is available the angler has 48 hours to report.
- Harvest reporting line: 877-FWP-WILD or 406-444-0356.
Pallid sturgeon is not a “check the size” fish
Pallid sturgeon
Montana’s current regulation framework identifies pallid sturgeon as endangered. All waters are closed to intentional fishing for pallid sturgeon and any fish encountered must be released promptly.
Identification matters
Montana supports several sturgeon fisheries and conservation programs. Do not assume that “sturgeon” automatically means the fish is legal to retain.
Bringing a boat into Montana adds another legal checklist
Stop at every open Montana watercraft inspection station you encounter.
All watercraft entering Montana must be inspected before launching.
Remove water from livewell, bilge and other compartments.
Remove plants, mud, animals and aquatic material.
Boats with ballast/bladders can require decontamination before launch.
Nonresident Vessel AIS Prevention Pass
Includes fuel- or electric-powered watercraft.
Includes kayaks, canoes, drift boats, rafts, paddle boards and similar vessels.
A Montana state fishing license does not erase Tribal fishing rules
Flathead Indian Reservation
Non-Tribal members must be licensed in accordance with the 2026 Flathead Indian Reservation regulations. Montana FWP and the Confederated Salish and Kootenai Tribes manage these fisheries under a cooperative agreement.
Before entering reservation water
Confirm whether the water is inside a reservation boundary and whether a Tribal fishing license, prevention pass or special waterbody license is required.
Charging entry fees or awarding prizes can turn fishing into a regulated contest
A contest with fewer than 30 people and prizes/cash worth $500 or less does not require the ordinary contest permit, but contest rules still apply.
Other qualifying contests must apply for FWP approval.
FWP prohibits contests involving wild trout in streams and rivers.
“Catch-and-release” does not make a closed afternoon legal
Hoot-owl rules apply to fishing itself, not only to fish harvest. You cannot avoid a 2 p.m.–midnight restriction by promising to release every trout.
Twelve Montana regulation errors that can ruin a fishing trip
Montana starts with district standards and then water exceptions.
Active restrictions prohibit fishing 2 p.m.–midnight.
Emergency closures change faster than the annual booklet.
Intentional bull-trout fishing is restricted to authorized Western fisheries.
The card is water-specific and physical.
Tag area, season, method and mandatory reporting control.
The July 1–August 31 Fort Peck Dredge Cuts fishery is archery only.
Montana’s 2026 regulations prohibit fish species as live bait there.
Out-of-state live baitfish import is heavily restricted.
Montana requires inspection before launch.
Flathead Reservation has a separate 2026 license/regulation system.
Release immediately; intentional fishing is closed.
Montana pre-trip regulation checklist
- Exact water: save the river reach, lake, reservoir or tributary name.
- Fishing District: Western, Central or Eastern.
- District standard: save the standard species limit and season.
- Named-water exception: screenshot it if your water is listed separately.
- Today’s restriction status: check hoot-owl and emergency closures the morning you fish.
- License package: Conservation License + Fishing License + applicable AISPP.
- Special permit: bull-trout catch card or paddlefish tag if applicable.
- Bait legality: confirm district rules before carrying or transporting live bait.
- Boat inspection: if entering Montana with watercraft, stop at all open inspection stations.
- Reservation boundary: verify separate Tribal licensing before fishing reservation waters.

Common Montana fishing regulation questions
When is the Montana 2026 fishing season?
Montana’s 2026 fishing regulations are valid March 1, 2026 through February 28, 2027. Western District rivers and streams are generally open from the third Saturday in May, which was May 16 in 2026, through November 30. Western lakes and reservoirs are generally open year-round. Central and Eastern District rivers, streams, lakes and reservoirs are generally open year-round unless an exception or closure applies.
What is a Montana hoot-owl fishing restriction?
A hoot-owl restriction prohibits fishing from 2 p.m. until midnight each day on the listed water or river reach. These restrictions are commonly used during hot-water and drought conditions and can change during the summer.
Does Montana have one statewide fish-limit table?
No. Montana first divides fishing regulations into Western, Central and Eastern Fishing Districts. Each district has standard regulations. If the exact waterbody is listed as an exception, that exception replaces the district standard for the rule it addresses.
How much is a Montana fishing license in 2026?
The base full-season fishing license costs $21 for a resident adult and $100 for a nonresident. Most anglers also need the applicable Conservation License and AIS Prevention Pass. A resident adult season setup commonly totals $31, while a nonresident age 16 or older season setup totals $117.50.
Do children need a Montana fishing license?
Montana FWP says anyone age 11 or younger does not need a fishing license, Conservation License or AIS Prevention Pass. Children must still follow all fish limits, seasons and regulations.
Can I use live fish as bait in western Montana?
No. Montana’s 2026 fishing regulations state that no fish species may be used as live bait in the Western Fishing District. Central and Eastern District live-bait rules differ and allow specified species under applicable restrictions.
Can I fish intentionally for bull trout anywhere in Montana?
No. Intentional bull-trout fishing is limited to specifically authorized Western District fisheries, including Hungry Horse Reservoir and an authorized portion of the South Fork Flathead system and Lake Koocanusa. A valid Catch Card for the specific water is required. All other Montana waters are closed to intentional bull-trout fishing.
What is Montana’s 2026 paddlefish season?
Paddlefish dates depend on the tag area. Upper Missouri runs May 1 through June 15, Yellowstone and Lower Missouri fisheries run May 15 through June 15, and the Fort Peck Dredge Cuts archery-only season runs July 1 through August 31. Mandatory harvest reporting applies.
Do I need an AIS pass to fish in Montana?
Montana requires an Angler Aquatic Invasive Species Prevention Pass with fishing-license purchases. It costs $2 for residents and $7.50 for nonresidents, with no fee for youth age 15 and younger. Nonresident boats can also require a separate Vessel AIS Prevention Pass.
Does a Montana fishing license cover the Flathead Indian Reservation?
Non-Tribal members fishing on the Flathead Indian Reservation must be licensed according to the separate Flathead Indian Reservation regulations established under the cooperative management system between the Confederated Salish and Kootenai Tribes and Montana Fish, Wildlife & Parks.
District → waterbody → today’s closure → species
That four-step order is safer than memorizing a statewide fish table. Montana’s annual regulations provide the foundation, but waterbody exceptions and summer emergency restrictions can change the legal answer.
Regulation research reviewed . Current hoot-owl and emergency closure information should be rechecked immediately before fishing because restrictions can change during the day or week.
