NO Very low at 716 CFS — boney and likely unrunnable. · Conditions as of Oct 18, 2026, 11:45 PM. Printed snapshot generated Oct 19, 2026, 12:31 AM— conditions change, wood moves, levels swing. Verify the gauge and scout anything you can't read from upstream.

The run

Long scenic float, not whitewater. Glacier NP boundary on river-left. Best as part of a multi-day. Wood hazards are the main concern.

⚠ Wood & hazard reports

  • May 26, 2026 — New wood buildup around Home Bottoms Ranch. It looks river-wide from upstream, but there's a gap on the inside corner to navigate through. (Trevor)
  • May 25, 2026 — Watch for strainers near Coal Creek. (Same report: everything ran clean at 6,000-7,000 cfs before the early-June rise.) (James)
