Description: About Owyhee River

Beginning in northern Nevada, the Owyhee River flows northward toward southeastern Oregon and southwestern Idaho before it joins, as a major tributary, the Snake River. The Owyhee and its tributaries gather watershed from the Owyhee Plateau. The river travels through steep canyon area, valley communities and the Duck Valley Indian Reservation. Once it crosses the Idaho border, it eventually meets up with the South Fork Owyhee River. As it passes through the lower southeast corner of Oregon, it combines with the West Little Owhyee River (from the south), the Middle Fork Owyhee River and the North Fork Owyhee River (both from the east). Other tributaries such as Jordan Creek, Rattlesnake Creek and Crooked Creek merge into the Owyhee as it makes its way toward the Snake River near the Idaho-Oregon border. Before the river officially meets up with the Snake, it’s stopped by the Owyhee Dam, which creates man-made Lake Owyhee. Below the dam the river then merges with the Snake River.
