The Breitenbush is one of the classic intermediate runs in the Cascades and a great introductory creeking run! But it is not recommended as an introduction to class IV. Even at moderate flows, this run as handed out some bad days for class IV paddlers who let their guard down.
At lower flows (below 700 cfs) most of the rapids are class III+ but come consistently throughout the first half of the run. At these levels the second half of the run can drag on as the river spreads out and the gradient drops. Because of this at low flows some boaters take out at the upstream end of the guard rail at Humbug Creek to get the action packed upper half of the run, while cutting out the gravel cruising and open class II of the second half of the run (at the cost of missing Barbell, Woo Man Chew, and a couple other class IIIs). Just be sure to note the take out area so you don't miss it from river-level. Because this portion is 4 miles long, you can take your time catching eddies, or grab a second lap.
At higher flows (1200+) you can expect a continuous class IV experience. For the most part the rapids can be boat scouted by experienced paddlers but keep a sharp eye out for wood which can be in play anywhere along this run. At medium levels and up the second half of the run moves along fast and is good fun, doing the full run at these levels (800 and up) and taking out at the gauging station is the way to go.
Beginning from the bridge upstream of Cleator Bend Campround, the river flows past the campground in an alluvial reach that has a tendency to collect large channel-spanning logs. Most people put in at the bottom end of the campground to avoid the potential for an early wood portage. As you come back along the road, you have an easy warm-up rapid before you soon arrive at a horizon line above The Slot.
The Slot is one of the more significant drops on the run and it's a good idea to scout and set safety from the bedrock shelf on river right--even if y
...
Starts off with a 4' ledge and then continues down a narrow bedrock chute.

Sometimes called S-Turn, Cyclops has a large hole dead center of the top drop. The trick is to move either left or right at the top to clip either side of the hole. At higher flows this becomes very difficult to do. The hole tends to flush to the left where there is a good eddy before the bottom half of the rapid which makes a sharp turn to the right through a narrow slot and then turns back to the left. There is usually a hole to avoid on each turn.

Ledge drop to river right requires a good boof or charge down the boulder garden on river left.

Potential access point when the reservoir is low.

Paddled the Breightenbush on 01/10 and there is a logjam roughly 15 minutes below The Notch; you can do an over/under on the right but, be careful, we had a pin. There's a huge logjam on Barbell, reducing the left channel to a boatwidth with root wad to negotiate: it's a class 5 move, given the meaty hole on the downside. Take the right channel into the eddy, then ferry between the hole and the rock wall. Video here:

Scouted for wood yesterday again in the hopes that I will get to raft it someday....(I need to get a kayak)
The log jam I previously posted about at Scorpio Creek is gone. There were a couple logs that looked duckable at mile 0.8 between the Slot and the Notch (viewable from the road at 44.780101, -122.011030).
I started making a map of the Breitenbush major rapids, scouts, logs, etc if anyone wants to use it:

The river was very turbulent at this flow. It felt higher than I would've thought based on the gauge reading with almost all rocks covered. Will be interesting to see if the gauge gets re-calibrated in the future or whether it currently matches readings from the past.
We put in below The Slot down a steep trail to a good launch spot. Portaging The Slot without running the narrow bottom section probably involves going up to the road and then down the steep trail we used. There was one fairly easy log limbo about 3 rapids or so below The Slot. Only stressful because of swirly current so would be very straightforward at lower flows. There was an easily seen logjam in one of the slower sections a couple miles into the run. Ample eddies on the left above it and a fairly straightforward portage to the gravel bar below the jam. Barbell currently has a large logjam effectively blocking both the right and left standard lines. At our flow there was a tricky line far right or an easy portage far right. Barbell can be easily scouted from the road on the way to the put in.
The river is still quite pretty despite the effects of the 2020 fire and subsequent hazard tree logging.

*EDIT: The log jam at Scorpio Creek is gone*
I recently scouted most of the run looking for new wood.
I saw a log jam forming where Scorpion Creek joins the Breitenbush (approx river mile 1.75). As of 12/1/2025 it was comprised of four logs, one of which had a large root wad hanging down almost touching the water. This has potential to get much worse if a few logs are added to the pile. At 330 cfs it looked duck-able by kayaks but probably not rafts. At higher water levels it may require portage. It is scoutable from Scorpion Creek Campground by hiking down the trail on the south bank of Scorpion Creek.
There is a rotary screw fish trap in the center of the river just below the bridge. It is passable on both river right and left for all craft. It is scoutable from the road.
There is also a log jam on river left around mile 7 just after the island. It is passable on the right. It is scoutable from the road.

HAZARD: Notch update 01/12/2019: The old scouting eddy on river right was not there. At 600 cfs, if you were to take the main line you would run out of surface water and end up in a sieve focalized in a root wad. Run the drop far left against the wall, this line ends in a straight forward 3' ledge............................Read the previous comment from cepaulo for more information.

The Notch has changed as of 12/31/18. I paddled it a week prior to this date and it was as normal. Typically, you run it river right, just left of a tree stump/root ball and slide down a small flake (as in the picture in the description). Now, much less water is running to the right side for some reason at 1000 cfs. If you attempt river right, you will essentially beach yourself on rock and need to push yourself along until you can scrape over the other side (at 1000 cfs or lower). For a cleaner line, it looks as if you'll need to go river left.
