Flathead River (mainstem) · Flathead Valley

Teakettle (Columbia Falls) to Old Steel Bridge (Kalispell)

One of the nicest floats on the mainstem Flathead. Wide channel with multiple braids and island scenery. Popular for float-fishing (westslope cutthroat, bull trout) and easy family floats. Easy access at both ends via established FWP sites. No whitewater.

Two Medicine North Shore Trailhead RerouteIn 2026, Two Medicine's North Shore Trailhead is not accessible due to construction in the Two Medicine Campground. A reroute has been established to access the North Shore Trail but does require a ford (unbridged water crossing). Directional signage is in place marking the reroute. Hikers may also access Twin Falls, Upper Two Medicine Lake, No Name Lake, and Dawson Pass without a ford, by using the South Shore Trail. Note: this adds approximately 1 mile of distance, one-way.NPS · Information ↗Going-to-the-Sun Road is Open for 2026 SeasonThe Going-to-the-Sun Road is fully open for the 2026 summer season. The road may now be accessed by motorized vehicles over Logan Pass from both the West Glacier and St. Mary Entrances.NPS · Information ↗

  • 2,000–25,000 prime band is a forum default

    The mainstem's prime range is a reasonable default from paddler-forum chatter — no American Whitewater page covers these flat-water reaches to calibrate against, so the badge is only as good as this guess. Paddler-forum chatter (v1 seed)

    At what Columbia Falls flows does this float get unpleasant — too pushy up high, or gravel-bar dragging down low?

  • No length or time on record

    FRA's access list stops upstream at House of Mystery and AW has no page for this reach, so the page publishes no mileage or time on the water at all. Flathead Rivers Alliance access list ↗

Is today the day?

↘
A read for what's actually running — not a generic class description. Updated with every gauge tick.

Good day to go

Flow is sitting in the meaty middle of the best-at range — the band we call fat enough to float, lean enough to read.

At 9,410 CFS this is a friendly run for boaters with a few days of experience, or anyone going guided. Family-friendly for strong-swimmer kids. Bring throw bags, helmets, and dry bags.
  • ✦Scout the crux. Eddy out above the marked rapid and look before you commit.
  • ✦Two boats, minimum. Long runs with no road. You are your own rescue.
  • ✦Helmet, throw bag, whistle on every paddler. Pin kit split between boats.
  • ✦Dress for the swim, not the float — dry layers waiting at the take-out.
  • ✦Tell someone your plan and the time you expect to be off the water.

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.

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.

Late May 2026 (Flathead Rivers Alliance): the forks are still rising with large woody debris moving in the channels. Check current conditions at flatheadrivers.org before launching.

Camping

Teakettle down to Presentine has lots of good overnight spots for small kids and a quick float out the next morning - the best bars show up at lower water, late summer.

The original conversations

North Valley Search and Rescue asked

North Valley responded to two flipped boats this month at the same problem area — just downriver from CFAC, river-right. The large rock has logs on it this season and there is a hole just upstream at current water levels. Thankfully, all rafters from both incidents were wearing PFDs and are safe and healthy. Please be safe out there and prepared for the unexpected.

TianaWe were one of the families that flipped — cannot thank North Valley Search and Rescue enough. Our family was split up and they worked fast to bring us back together, and the community stopped to help and found our belongings along the way.
DavidWe ran this yesterday — the logs were gone. Even so, this section has plenty of space to navigate around any obstacles.
