Hi crew! Interested in doing Bear Creek to Cascadilla tomorrow. We have run this stretch many times but never at these flows. Looks to be running around 11k. Any advice, intel, words of wisdom?
Moccasin Creek to West Glacier
The classic Middle Fork whitewater run. Approximately 3 miles of mellower water below Moccasin before rapids begin in earnest. American Whitewater lists eleven named rapids in downstream order: Tunnel, Bonecrusher, Washboard, Big Squeeze, Screaming Right, Jaws, Pinball, Repeater, CBT Rapids, The Notch, Pumphouse. Some features (Jaws, Pinball) only form at higher flows and wash out below ~2,500 CFS. Paddleable as low as ~730 CFS (Jaws/Pinball washed out, mostly II–III).
What the river is doing today

Zones are a community estimate — no agency publishes a flow window for this run. Today's flow sits in the band of the same color. Dashed forward lines: the NOAA NWPS short-range forecast ↗ on 7-day & 30-day, and the NWRFC ensemble outlook ↗ on Season.
ON THE WATER
Is today the day?
↘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.
Gut check“Confident intermediate” is a question, not a label: would you be comfortable swimming a rapid this size, in water this cold? If not, that's your answer for today.
- ✦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.
Mile by mile
↘Read-and-run at most flows — but rivers change. Scoutanything you can't read from upstream, and treat a flaggedportage / scout note below as the minimum, not the whole story.

West Glacier
11.2 mi self-shuttle
- 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.
What to watch for
↘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. — Barbara / AJ
No standout hazards are flagged for this run — which is not the same as none. Woodmoves and channels shift; scout anything you can't read from upstream.
- 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. 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.
Today's gear call

What the last few boats said
↘From the group
↘Safety
Mid-May 2026: lots of trees/wood reported in the river and it's running muddy and off-color. Be on your game.

Paddleboarding the Moccasin section — wear a helmet and a vest.
The run
Browns Hole at high water (~11k): start left and move right as you enter, avoid the wall on the left, and eddy out to scout — the wave can be as tall as a 14' boat is long.
Moccasin is read-and-run, but boily and swirly — expect continuous, pushy water rather than clean discrete drops.
Conditions
Late May 2026, ~6 ft: Cascadilla → West Glacier is tan-green with about 4 ft of visibility. Two non-threatening strainers ~2 miles above where Moccasin/Deerlick Creek enter; obstacles are visible well ahead. Tunnel → West Glacier is fast and semi-smooth, not washed out.
Moccasin is best mid-summer, when flows bring out the rapids; late summer gets too low. One paddler's gauge-stage read (note: gauge height in feet, not CFS): good around 3–4 ft for a raft, 2–3 ft for a kayak.
Is it for you
Bear Creek runs better at higher flows — high water covers a lot of the rocks so it's less bony.
At high water on the Bear Creek run you want real experience on it and dry suits.
The original conversations
Will be over near the Middle Fork. Looking for someone to show me the way down from Moccasin Creek to West Glacier, Saturday 5/9/26.
Did a shakedown run today, Cascadilla to West Glacier. Tan-green water at I'd guess 6 feet. Two non-threatening strainers about 2 miles above where Moccasin/Deerlick Creek enter. Stayed in the main channel, mostly — can spot the obstacles well ahead of time, so in my opinion a novice can do it, depending on boat size. The water from Tunnel to West is fast, semi-smooth but not washed out. Visibility about 4 feet deep.
Looking for some insight. My friend and I come up every year and float on SUP's from HH to Teakettle or Kokanee. We've done Blankenship to Teakettle and HH to Old Steel Bridge before. Those are the only routes we know. Are there any other stretches of the river that you'd recommend? I've done white water rafting a few times and have been paddling the river on my SUP for around 4-5 years. Nothing crazy though, and no training.
Hoping to sneak an overnight float in over Father's Day weekend — ideally a short float you could normally do in a day, camping somewhere along the way. Introducing our small human to river camping; we have technical whitewater experience but want nothing crazy with our passenger.
