Designates about 126,554 acres of Federal land in the Olympic National Forest as new wilderness and adds many river segments in Washington to the National Wild and Scenic Rivers system. The measure withdraws the newly designated federal lands from most forms of mining and leasing (while protecting valid existing rights), requires the Forest Service to update management plans to reflect the new designations, allows limited active management for fire, insect and disease control, and preserves tribal treaty rights and existing private rights.

The bill also identifies about 5,346 acres as potential wilderness that will convert when nonconforming uses end, allows certain river‑restoration and species‑recovery projects, and directs which federal official will administer each new Wild and Scenic river segment.
