⚠ Wood & hazards
- May 25, 2026 — Late May 2026: Jaws is 'gnarly' right now — high, fast, and punchy; it flipped a mini-raft (swimmers OK). A paddler lost a flip line and a locking carabiner in it — a possible entrapment hazard for others. Bonecrusher, by contrast, was reported small. Expect brutal wind in the corridor too.

Emergency
- 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.
- Nearest hospitals. Logan Health Whitefish and Logan Health Medical Center (Kalispell) are the primary regional facilities; serious trauma is flown to Kalispell or Missoula.

Mile by mile
- 1 TunnelIII · RM 19.8 — Named for the railroad tunnel on river-left. Current accelerates into a series of waves and small holes that set the tone for the run. Good warm-up — clear lines, fun wave action.
- 2 BonecrusherIII · RM 19.4 — Begins where the river bends back to the left. Formed by boulders with a hole at the bottom. At higher flows: large waves and a few strong holes. Main current pushes hard into the center; straightforward lines with attentive boat placement. Packs more punch at high water.
- 3 WashboardII · RM 18.4 — Long series of continuous wave trains. Bouncy, splashy fun — read-and-run with few technical moves.
- 4 Big SqueezeIII · RM 18 — River passes between bedrock outcrops that narrow the channel, creating pushy water and large diagonal waves. Demands precise boat control to stay clear of surging laterals. Short but powerful — especially challenging at higher flows.
- 5 Screaming RightIII · RM 17.7 — Current flows over a ledge down the left, then accelerates to the right into a strong wave train and lateral features that live up to the name. Energetic and fast — stay centered and ready to punch through waves.
- 6 JawsIII-IV · RM 17.5 — Standout rapid with large breaking waves and a dynamic main hole. Lines vary with flow; strong surf potential at the right level. American Whitewater rates this Class IV at high water; at lower flows it washes out to easy Class II.
- 7 PinballIII-IV · RM 17.1 — True to its name — scattered boulders and bedrock walls create pushy currents. At most flows it's playful but requires attentive maneuvering; at lower flows it washes out to easy Class II. AW rates Pinball Class IV at high water.
- 8 RepeaterII · RM 16.6 — Gravel bar on the left, rock wall on the right. A string of similar-sized waves and holes one after another — consistent action over its length.
- 9 CBT RapidsII-III · RM 16.4 — Named for the Coal Bank Turnout on Highway 2. Mix of waves and diagonals that feel bigger than they look from shore. Surprisingly pushy at medium to high flows — quick reactions and momentum are key.
- 10 The NotchII-III · RM 16.2 — Funnels through a narrow slot, creating a strong constriction in the current. At higher flows: pushy, with powerful waves and turbulent eddies. One of the more technical features on the run.
- 11 PumphouseII · RM 15.3 — Boisterous finish with big waves and swift current — straightforward but splashy. Many groups stop near this rapid for lunch in summer.
