The Wenaha River is a 22-mile (35 km) river in the Wenaha–Tucannon Wilderness in the U.S. state of Oregon. The river begins at the Wenaha Forks, where the North and South Fork Wenaha Rivers join. It then flows east for about 22 miles (35 km) to the small settlement of Troy where it meets the Grande Ronde River.[1][2] Most of the Wenaha watershed is rugged and steep, with mostly unpopulated mountain peaks and gorges.
