The Summit Run is a novelty; easily seen from Interstate 80, this run contains some fun rapids, some not so fun rapids, and a little bit of flatwater. This run winds its way through granite boulders, which produces interesting drops and the occasional slide.
There seems to be an ever changing wood situation, so please be on the lookout. A few rapids are worth a look, as the horizon lines can be a little bit confusing at times. Shuttle is extremely easy, all of the run is roadside.
The recommended flow is anywhere from 800 to 1500 cfs.
Access Logistics
Take Out: Two takeouts exist. The first is just off the Cisco Road exit. The shorter takeout is just up the road. Both involve taking out on river right.
Put In: https://maps.app.goo.gl/gPa9zT4NVHkpWkEo6 is likely the best put in, as it adds several fun rapids beneath the Interstate 80 bridge. There may be a put in higher upstream that is not commonly used.

At 800 cfs, this was a portage for most of the group. Lots of wood, and a lot of tight channels to just barely squeeze down.

Evening after work run for these paddlers. They said it was a little boney at this flow, 'A bit more water would cover up a lot of the rocks.' As shuttle driver and cameraman, I had no complaints!
