The Wallowa Valley was home to Chief Joseph's band of the Nez Perce Tribe. Chief Joseph asked the first white settlers to leave when they arrived in 1871.[6] The U.S. government expelled the tribe and seized their property and livestock in 1877,[6] when non-Indian farmers and ranchers wanted to settle the fertile Wallowa valley. The tribe was barred from returning to their homeland by the government after repeated petitions. The tribal members were shipped in unheated box cars to Indian Territory (now Oklahoma) to be placed in a prisoner-of-war camp never to see their home again.
It then flows past the communities of Joseph, Enterprise, and Wallowa. Further upstream it receives the Minam River from the left at the hamlet of Minam. Continuing north another 10 miles (16 km), it joins the Grande Ronde along the Wallowa–Union county line about 10 miles (16 km) north-northeast of Elgin and about 81 miles (130 km) from the larger river's confluence with the Snake River.[4]
Fish
The Wallowa River supports populations of steelhead, spring Chinook salmon, and 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.
