The Wallowa Valley was home to Chief Joseph's band of the Nez Perce Tribe, from which they were expelled in 1877. They were expelled when non-Indian farmers and ranchers wanted to settle the fertile Wallowa valley.
Fish
The Wallowa River supports populations of steelhead, spring chinook salmon, mountain whitefish among other species. Sockeye salmon were extirpated from the Wallowa River when a small dam was constructed at the outlet of Wallowa Lake in the headwaters of the river. The dam was constructed to raise the level of the lake to store water for irrigation.
