Middle Fork Flathead · Flathead Valley / Glacier National Park

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).

No. 04 · The run

Mile by mile

↘
Continuous read-and-run whitewater. The most popular day-trip whitewater run on any of the three forks. Railroad along river-left, Glacier National Park on river-right. American Whitewater ↗

Read-and-run at most flows — but rivers change. Scout anything you can't read from upstream, and treat a flaggedportage / scout note below as the minimum, not the whole story.

mi 3.5Tunnel

TunnelIII

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.
mi 4Bonecrusher

BonecrusherIII

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.
mi 5Washboard

WashboardII

Long series of continuous wave trains. Bouncy, splashy fun — read-and-run with few technical moves.
mi 5.5Big Squeeze

Big SqueezeIII

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.
mi 5.8Screaming Right

Screaming RightIII

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.
mi 6Jaws

JawsIII-IV

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. AW ↗
mi 6.5Pinball

PinballIII-IV

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.
mi 7Repeater

RepeaterII

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.
mi 7.3CBT Rapids

CBT RapidsII-III

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.
mi 7.5The Notch

The NotchII-III

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.
mi 8.5Pumphouse

PumphouseII

Boisterous finish with big waves and swift current — straightforward but splashy. Many groups stop near this rapid for lunch in summer.

Put-in

Moccasin Creek

48.4525, -113.8290Directions ↗
Notes
Well-signed access along Highway 2. Most popular launch on the Middle Fork (~73 crafts and 449 people per day average in 2018). Closest launch to the major whitewater. Heavy outfitter use. PUT-IN ONLY — the access site sits on a side channel upstream of the main river and is very difficult to find from the river. If you miss it from upstream you continue into the biggest whitewater.
Take-out

West Glacier

Notes
Large cobble-bar take-out off River Bend Drive on river left. Higher-clearance vehicle recommended — passenger cars can bottom out on river cobbles. Heavy outfitter use; parking lot for trailers. Do not park on the beach. Private property adjoins — respect neighbors. Hand-carry craft can also exit upstream at the historic Belton Bridge via a short steep trail.

Safety

LeeRecent report

Mid-May 2026: lots of trees/wood reported in the river and it's running muddy and off-color. Be on your game.

Barbara / AJRecent report

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.

CajunAlways true

Paddleboarding the Moccasin section — wear a helmet and a vest.

The run

Jimmy11,000 cfsFlow-dependent

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.

JonAlways true

Moccasin is read-and-run, but boily and swirly — expect continuous, pushy water rather than clean discrete drops.

Conditions

RobertRecent report

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.

JonFlow-dependent

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

Andy11,000 cfsFlow-dependent

At high water on the Bear Creek run you want real experience on it and dry suits.

LehiFlow-dependent

Bear Creek runs better at higher flows — high water covers a lot of the rocks so it's less bony.

The original conversations

Natasha asked

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.

CassidyI like middle fork golf course to Blankenship.
CajunYou need to start at West Glacier! Take out at House of Mystery. Best stretch imo.
NatashaHow long? Rapids? Do it with someone knowledgeable first?
CajunYou don't need a guide to do anything below Moccasin.
CajunYes rapids, but nothing crazy.
CajunWest Glacier to Blankenship is a little rougher than Blankenship down, in terms of whitewater.
RoyWhen are you coming? The water level makes a big difference. As Cajun said, consider West Glacier to Blankenship. There is one rapid, Devil's Elbow, worth mentioning. The river makes a big turn to the right. At medium and higher flows the current pushes you into the big rock outcrop. You can totally avoid it by portaging over the gravel bar on the right.
CarmenJust not on a remotely windy day! That last part will blow you backwards up the river!
CajunOh, I should've mentioned that. Always check the wind forecast before getting on the river.
CajunI've paddleboarded Moccasin, but I recommend a helmet and vest for that.
NatashaWe usually come mid-to-late July.
RoyA good time of year for SUP. Unless we just got a bunch of rain, the flow should be on the lower side of moderate. Definitely West Glacier to Blankenship. It'll probably be a good level to play around in Devil's Elbow — carry back up and run it multiple times trying different lines, and practice ferries, eddy turns, and peel-outs at the bottom. Have fun!

Hannah asked

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?

LeeRan it last year at 11,000 — it's a bunch in places. Depends on your experience. A friend who lives on the river said this morning there are a bunch of trees in the river now and it's muddy.
AndyAt this water level, you should have some experience on that stretch and dry suits if you plan on running it.
JimmyStart left and move right as you enter Browns. It'll be HUGE. You really want to avoid the wall on the left. Definitely worth an eddy-out and scout.
AndrewDrove through the area today coming from the east side. It's pumping and off-color, as expected. Should be fun, but definitely be on your game.
JessicaI wanna run this section, but not right now. Way too much wood in the water.
SamuelDefinitely scout Browns. Last year we ran it at 11k and the wave was about as tall as my 14' boat is long.
LehiBrowns Hole should be a fun wave. I prefer Bear Creek at around those levels — it clears up a lot of the rocks and it's not so bony.
Ed asked

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.

JonJust did it. Boily and swirly.
JonThe best is mid-summer, when it brings out the best of the rapids. Late summer is too low. For a raft, likely between 3 and 4 feet on the gauge; for a kayak, between 2 and 3 feet. It's still fun lower, but it's not as good a high-water river as others.
JaronRead and run.

Robert asked

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.

BarbaraVery splashy through the whitewater section. Jaws is gnarly — chewed up my little mini-raft and spat us out swimming. We were fine, but it's high, fast, and punchy right now. The only thing I lost in Jaws was my flip line, tucked behind the clamshell pocket of my PFD — and a locking carabiner. Hopefully it doesn't become an entrapment hazard for someone else.
AJWe floated Moccasin to Blankenship yesterday. Water was fast, but the wind was horrible — had to fight just to get into Tunnel Rapids, and it was basically just rollers. Bonecrusher was small and not much action.
