River Description

SEASON: The annual flip-flop typically occurs on our around the weekend after Labor Day. At that time, flows from the Yakima are reduced and flows on the Tieton are increased to serve irrigation interests downstream providing good boating through much of September.

FUN FACT: The last "summer" run

DESCRIPTION: Be warned that you want to take out before you reach the confluence with the Naches River as just downstream of this point there is a dangerous low head dam.

August 22nd 2018. 725 CFS. We ran about 3 miles of the Tieton River, from the access point at River Mile 5 (good place to leave a car), down to River Mile 2 where there’s an easy left takeout just before the foot bridge that spans the river and across from the Oak Creek Wildlife Recreation Area Headquarters. The water is low at 725 CFS. In a one-seat Outlaw IK, the good maneuverability is an asset. Several sets of boulders sticking part way out of the water, close together is some stretches and needing paddle work to wend through. About 3/4 mile before the end is the most challenging boulder segment. The fellow I ran with was in a one seat Sun Dolphin sit-on kayak; he overturned in this segment. The Sun Dophin had less maneuverability, in part due to having somehow absorbed a fair amount of water/weight inside the shell. The bottom of my IK has more rub marks than before, but nothing serious. I only hung up a few times in low spots, which could have been avoided by paying less attention to the camera and more to the river. Total weight load in the IK, including equipment, was about 175 pounds. Air quality was low today (about 55 ug/m3 of PM2.5 = “Unhealthy” per WA DOE) due to the forest fire up on White Pass. But for up here, for this week, it was a relatively good few hours of air quality. In summary, a relatively easy run in an IK, lots of maneuvering to do, no hidden dangers or concerning challenges, you’re moving right along. It was good to get some water time, but I’m really looking forward to running it when there’s more like 1,500 cfs. 46.71662 -120.85975: put in 46.71779 -120.81693: Sun Dolphin kayak overturned in boulders 46.72585 -120.81190: take out WGS84

This lower section was a ton of fun when we did it twice at 1500 in 2006. The book seems to imply that there is much more wood that we saw. The river moves so fast, with so few eddies, that it is extra important to watch for sweepers and strainers, but we didn't see very many. Several of the rafting companies go a fair ways down the lower stretch, and Wildwater River Tours goes the whole way to Tim's Pond river access area. All of the commercial guides on this river are very friendly and helpful in my experience, so you could ask one of them about new obstacles.

You can also put in at Waffle Wall to extend the trip, but skip the weir and some of the longer hairy Class III channels.
Waffle Wall is the first dirt turnoff on the right going downriver from Rimrock Retreat, at about Mile Marker 173.5. If you get to the "town" (cluster of buildings) at Marker 172.9, then head East, that is the easiest way to find it.

You can take out at Tim's Pond, mile marker 184.5 (+/-). This point is a little over one half mile upstream from the confluence with the Naches. The most signficant rapid is called Surprise because it sneaks up on you. After miles of continuous Class II, with intermittent bigger rapids, we dud not realize we were in the middle of it until we started running out of ways to easily dodge the holes.
It's a very pretty stretch, with some time for checking out the unusually tall columnar basalt, and to look for rock climbers and mountain goats.

A couple more notes: The water is warm. You will need a river access pass to park at Tim's Pond. The take-out at Tim's Pond is a little hidden, it is at the down stream end of the pond, and you can see where rafts have been dragging up the banks. If you run from lake clear to Tim's Pond, as we did, it is 17 miles. It is fast miles, but you have to pay attention the whole way.

This stretch doesn't see nearly as many boaters as the upper stretch, but if you're coming from the Seattle area, it's worth extending the upper run with the lower. Or, if you're like me and you prefer not having to wait in line to run rapids, this run can be a nice alternative to the crowded upper section.

The best rapid on this section comes at the end of the recently-burned section, about 3 miles from the confluence with the Naches. The rapid is a long (1/2-mile?) continuous boulder garden that at over 2000cfs is full of big holes and waves. In a kayak, this section is a blast.

Gage Descriptions

The gauge is maintained by the U.S. Bureau of Reclamation's Yakima Project (flow information also available through from the Army Corps gauge). The source of water for this section is Rimrock Reservoir. A level between 1000 and 3000 cfs is ideal. You can contact the flow information line at 509-575-5854 which will provide you with a daily conditions and the plan for the next couple days. The same information is also updated daily on the Yakima Project System Status page.

Tieton River (WA) releases 2007

Thomas O'Keefe

Fall releases on the Tieton River begin this week. Recreational boaters and commercial outfitters benefit from the dependable fall releases that come at a time when other regional rivers are at a seasonal low. We expect flows to last through the month of September.
