Flathead rivers are still on the rise with large woody debris moving in river channels. Current river conditions at flatheadrivers.org. Photo: below the confluence of the South and Middle Forks before Badrock Canyon.
Flathead River (mainstem) · Flathead Valley
Blankenship Bridge to Teakettle (Columbia Falls)
Starts at Blankenship Bridge where the North and Middle Forks meet to form the mainstem Flathead, then runs ~10 miles through the upper mainstem to the Teakettle FAS at Columbia Falls. Wide channel; Class I scenic float. The South Fork joins from the east about 5 miles below Blankenship at the eastern end of Bad Rock Canyon. House of Mystery (roughly mile 7, river-right near US-2) is an informal mid-section take-out option; pairs naturally with the next-downstream run (Teakettle → Old Steel Bridge) for a full mainstem day. Float traffic is light most weekdays, busier on warm summer weekends.

Very high at 42,000 CFS — flood-stage; do not launch.

No. 02 · Honest read
Is today the day?
↘A read for what's actually running — not a generic class description. Updated with every gauge tick.
Not today
Far over the best-at range — flood-stage water moving wood and pushing hard into every wall.
Don't launch today. Come back when this drops below 25,000 CFS. The river will still be here next week.
- ✦Wait it out. Flood flows move wood and strainers — the hazard is invisible from shore.
No. 04 · The run
Mile by mile
↘The upper mainstem — confluence-to-Columbia Falls. Wide, scenic, mostly Class I with strong steady current. Bad Rock Canyon scenery and the House of Mystery as a midway landmark; the South Fork joins about 5 miles below the put-in.
No named rapids are recorded for this run.
No. 05 · Getting there & back
How to get there. How to get back.
↘Put-in, take-out, and the shuttle between them. Confirm road conditions before a remote launch.
Put-in
Blankenship Bridge
48.4740, -114.1150Directions ↗
Notes
Just upstream of the bridge on river-left is the formal river access. County non-fee campground on opposite bank. WATCH the bridge pylons — wrap potential. Reachable from Highway 2 above Coram.
Take-out
Teakettle (Columbia Falls)
48.3670, -114.1810Directions ↗
Notes
FWP access below the Highway 2 bridge on river-right. Nice boat launch.

Route
Spot a vehicle at the take-out, drive boats to the put-in, retrieve at the end of the day.

Driving distance via the Mapbox Directions API; matches a standard road shuttle, not a back-road shortcut.

Season
May–October. Long, forgiving season on the mainstem.
Rules & regulationsvia Flathead Rivers Alliance ↗
- Personal flotation device. A USCG-approved PFD must be carried on board for every person. Anyone 12 or under must wear a PFD while the vessel is underway.
- Bear-resistant food storage. IGBC-approved bear-resistant food storage is required in the river corridor — this is grizzly country.
- Human-waste containment. Self-contained or solid human-waste containment is required on the Middle and North Forks (recommended on the South Fork).
- Fire management. Fire pans or fire blankets are required or strongly recommended; camp stoves are preferred over campfires.
- Aquatic-invasive-species inspection. An AIS inspection (NPS and Montana FWP) is required before launching anywhere in the basin.
No. 06 · Hazards on this run
What to watch for
↘Hazards we have on record for this run specifically. Universal river-safety practice — gear, group, emergencies — is on the disclaimer & safety page.
No standout hazards are flagged for this run — which is not the same as none. Wood moves and channels shift; scout anything you can't read from upstream.
Corridor contactsvia Flathead Rivers Alliance ↗
- Emergencies. Dial 911. Cell coverage is limited throughout the corridor — plan to be self-reliant between accesses.
- Primary rescue. North Valley Search & Rescue covers all three forks of the Flathead.
- FWP warden. Tyler Melville (North Fork) · Ben Chappelow (Middle and South Forks)
- Nearest hospitals. Logan Health Whitefish and Logan Health Medical Center (Kalispell) are the primary regional facilities; serious trauma is flown to Kalispell or Missoula.
- Life-jacket loaner stations. Free loaner PFDs are available at the West Glacier and Glacier Rim access points, Memorial Day through Labor Day.
