Imnaha, Oregon, US
|Usual Difficulty||III-IV (for normal flows)|
The 7 miles below the town of Imnaha is pretty flat flowing through ranch land (mainly class I and II with an ocasional class III move). The scenery picks up at Fence Creek where the road turns to dirt and this is probably your best put-in option. Below this point the scenery is stunning! The whitewater is mainly class II and III. After Cow Creek the river pick up a bit. Class II and III with a few class IV moves thrown in. No big rapids, mainly one move type scenarios. Lots of fun eddy catching moves in this strecth. Not too hard, but really fun. The hike back up to Cow Creek is not bad. Mostly flat with a few small uphill sections. Bring long pants for the hike due to poison ivy. The alternative is to continue on the Snake down to Heller Bar. If your are in the area, this run is well worth it for the stunning scenery alone. The fun somewhat technical whitewater is a bonus.

The old gauge for this section that read in cfs is no longer available. The gauge that is now associated with this river section only has data in the feet stage metric. So, as a workaround, you can check the cfs listing on the Idaho Power site. The previously listed low to high range for a similar cfs reading gauge for this section was 900 - 2000 cfs.
