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.
