River Description

This section of the North Fork Lewis is a beautiful and short scenic run with fairly continuous class II and a couple of rapids that push class III particularly at the higher flows. You can put-in at the FR 9039 bridge where a short scramble on the downstream river right side of the bridge gets you down to the water. You are immediately swept into a beautiful gorge with fun rapids along the weigh and as you round one of the first corners you will be greeted by the spray from Curly Creek Falls. This waterfall is one of the most impressive sites along any river in the region with a double step cascade that flows under a natural rock arch. You can play around in the spray at the base of the falls.

Continuing on downstream there are a couple more falls, seeps, and springs that enter the gorge and maintain a lush native plant community that thrives in the spray zone along the rock walls. About halfway into the run the walls peel back and the river opens up into a broader alluvial valley. There is still plenty of graident and some fun rapids but beware of a few log jams that form along the edges of the river. As you pass Pine Creek which comes in from the right the river descends through one last stretch of nice whitewater as you pass beneath the Eagle Cliffs and the take-out bridge comes into view.

This is a short run but a great option if you are in the area and passing through. With good camping and hiking options in the area it's a great option if you are enjoying a multisports weekend on the Gifford Pinchot National Forest. Some guides describe an alternate put-in at Rush Creek but this road was closed a few years ago. For a longer run you can add on the upstream run and some groups even do this as an overnight trip.

The best access is on the downstream river right side of the bridge. You can also hike up the trail on river right (a good option for packrafts) and add some more river miles by doing the run that ends here.

The Eagle Cliffs access is a day-use area administered by PacifiCorp as a recreation site associated with their hydropower project. The access is on river left just above the bridge and before you hit the slackwater of the reservoir.


We got the kids out for a short evening float over spring break from the FR 9030 Bridge down to the Reservoir. It's a good beginner-friendly trip at these flows with a scenic view of Curly Creek Falls as the highlight.

Tom O'Keefe, Greg Lee, and Bryan Stewart met up for a North Fork Lewis trip with a bike shuttle.
