Description for the Grande Ronde River (Oregon)This section covers the portion of the river in the state of Oregon.
The Grande Ronde River is roughly 182 miles and begins in Oregon's Elkhorn Mountain Range and eventually flows into the Snake River in Washington. The river is one of the finest fly fishing steelhead rivers in the Pacific Northwest. The Ronde offers fisherman a unique opportunity to take a steelhead on a dry fly. Due to its warmer climate, temperatures remain moderate all the way through October. A portion of this river leaves the road and consequently sees minimal pressure during the season. Steelhead typically range from 5 to 10 pounds.
