Public lands of the Grande Ronde are managed in part by the Bureau of Land Management, U.S. Forest Service, and the States of Oregon and Washington. The river canyons in Oregon have been designated as both National Wild and Scenic Rivers and State Scenic Waterways, in recognition of their unique natural character and outstanding resource values.
