The Imnaha River is a tributary of the Snake River located in northeastern Oregon, stretching approximately 73 miles in length. The river has played a significant role in the history of the region, serving as a vital resource for Native American tribes, explorers, and early settlers.

History of the River
The Imnaha River is a 73.3-mile-long (118.0 km) tributary of the Snake River in the U.S. state of Oregon. Flowing generally east near the headwaters and then north through Wallowa County, the entire river is designated Wild and Scenic. It follows a geologic fault to the Snake River, and in addition to land in the Wallowa–Whitman National Forest and private land, its corridor includes parts of three special management areas: the Eagle Cap Wilderness, Hells Canyon National Recreation Area, and Hells Canyon Scenic Byway. The Imnaha flows by the unincorporated community of Imnaha, the only settlement along its course, and enters the Snake River roughly 4 miles (6 km) from the larger river's confluence with the Salmon River of Idaho and 192 miles (309 km) from its confluence with the Columbia River.
