The Wenaha River flows west to east for 20 miles from the Wenaha Forks where the North and South forks join to form the main Wenaha, to Troy, where it empties into the Grande Ronde River.
For the fishermen, wild resident populations of rainbow trout are abundant, and offer an excellent opportunity for fly fishing. Access to the river is by trail only, so this is a perfect secluded fishing river. There are also many places along the river for camping.
