General Info:

One of the most remote regions in Oregon, the Imnaha river runs 73 miles from high up in the Eagle Cap Wilderness until it joins with the Snake River a little down stream of Doug bar.  Amazingly, nearly all of this rugged river is accessible by trail and roads of varying condition.  The Imnaha canyon is spectacularly scenic in its entirety; from gin clear deep pools high up stream surrounded by mountains, to craggy canyon country surrounding the quaint community of Imnaha and continuing downstream.  Home to native Steelhead, Rainbow Trout, Bull-trout, summer Chinook, and plenty of rattle-snakes, elk, deer, big horn sheep, birds of prey, and black bear; a trip down the Imnaha river corridor might be the closest thing there is today to being part of the Lewis and Clark Expedition.  What ever fishing adventure you are after, the Imnaha is sure to offer an unforgettable experience .

The lower river is a wonderful little steel head fishery. The mid river can be a fair to good trout fishery.  The upper river near the FS campgrounds off Hwy 39 is a poor trout fishery because: native trout are not protected; the river is not stocked with trout; the river is glacial fed and does not have many nutrients; and campers tend to “fish-out“ this section of river.

Thanks to the Nature Conservancy and Forest Service, the lower river (the bottom 12 miles from Horse Creek to the Snake) has good public access.  There is also a good easement upstream (south) from town for the first three miles.  However, the mid river above and below town is mostly private and should not be trespassed.  Oregon laws are tough.  It is ILLEGAL to hunt or fish on private property without permission – it does not have to be fenced or posted.  However, recent information from the Oregon Attorney's Office suggests that if you can float a river in a boat, you can wade and fish it below the high water mark - if you don't trespass when accessing the river.

Imnaha River Reports:

7/12/18:  According to Dave at the Imnaha Store and Tavern, trout fishing has been a bit slow.  Water levels and temps are still pretty good, so that should change as the hoppers arrive in full force.  Some fishers are heading to Cow Creek looking for bass and trout, or the upper river looking for bull trout.

7/4/18.  The river has dropped sharply the past few days and it is easier to wade into the river.  Hoppers are starting to come out - a particularly easy way to fish for trout (cast across stream then lift and dip the rod to simulate a hopper struggling then giving up then struggling again).  There is good access on a fishing easement that starts a half mile above town and extends upstream for approx. 2.5 miles above town.

6/29/18:  Still high, but some flyfishers had good bulltrout fishing on the upper river, good fishing on Big Sheep Creek, and fair trout fishing on the Imnaha near town.  Still a few stone flies, but hoppers should be out soon.  Expect the river to drop soon.

6/6/18:  Still pretty high.  Should be better in a couple weeks.  Salmon flies and golden stone have moved upstream to town, but trout may not feeding on them yet.  if nothing is surface feeding, try a bh hare's ear along the bank.  Or look for a nice bull trout with a large bh black woolly bugger.
