Tieton, S. Fork

We had a nice day checking out the SF Tieton from below Butcher Block to the Rimrock Resevoir. The forest road 1200 bridge across the SF Tieton is out until ~2027, so we had to access forest road 1000 from the west side of the lake. There were a few logs spanning the channel that we found pretty easy to walk over / around.

Ariel, Brett, and I paddled the SF of the Tieton 5/3/26 on a nice sunny day. Flows were low but passable at 800cfs on the inflow to Rimrock Reservoir. If I were to go back, I think I'd like to see it at 1200cfs. There were some boulder gardens that would be a bit more exciting with more water. But there was also wood throughout the river, so I'd want to be cautious before going too high.

We actually did two laps, the first lap we put in below the easier version of butcher block.

We parked the car on the shoulder above and followed a fairly well trodden, surprisingly gradual, trail down to the river. The only steep part was dropping the first 15 feet from the car.

Most of the river below this point felt to me like class II+ or III- boulder garden style rapids. Maybe it would bump up half a level with more water. The road is generally a couple hundred feet above the river, so the river has more of an untouched feel. There is a bridge a mile and change above the take out that can be used as an alternate access point. Most of the better boulder gardens are below this point anyways.

We used a takeout about a quarter mile upstream of the SF 1200 bridge. The bridge was kinda a construction area and the takeout spot had a nice sandy beach to chill at after the run. It was a few hundred yards walk to the car from there.

The next lap we put in a bit higher, below the class V butcher block.

We parked at a shoulder, walked up the road a bit, and dropped down. We never did find much of a trail, just a bunch of cow poop, but the trail down was pretty gradual and not too bushwacky.

This section of river was more class III-. Little butcher block, which can be scouted from the road high above on the way in, felt class III+ at low flow, I could see it pushing IV- with more water. The entrance right hand turn pushes you left into a picket fence of boulders clogged with wood. After driving right to avoid that, we changed gears and immediately drove left to avoid a couple tight boulders. Then it's just a ho diddle diddle, right down the middle, couple of fun drops / waves. Fun rapid once you get past the wood!

We continued down the section we had previously run, the second lap clocking in at a quick 3.3 mile run. Ran back to get the car, not a single car passed by late Sunday evening
