Experience the Clearwater Basin
Idaho’s Clearwater Basin includes a 6 million-acre landscape that rises from Idaho’s Palouse prairie into a craggy, moss-draped wilderness. The area known as Clearwater Basin is the native land of the Nez Perce Native American tribe and is one of the wildlands that Lewis and Clark explored.
The Basin gets its name from the Clearwater River, which drains the majestic 1.3 million acre Selway-Bitterroot Wilderness. Selway-Bitterroot is the third largest wilderness area in the continental United States.
What the one best thing about the Clearwater Basin?
It’s a rare inland oasis.
Located in the heart of Idaho, Clearwater Basin’s 2,000 miles of wilderness trails weave along emerald rivers and streams.
What’s one activity the Clearwater Basin is known for?
Fishing.
Steelhead and Chinook salmon migrate inland from the Pacific Ocean to spawn in pristine streams, like Meadow Creek and Kelly Creek.
For the threatened cutthroat trout, Kelly Creek is an important habitat. It was an original “catch-and-release” test stream. Kelly Creek is still catch-and-release, which has allowed the native trout population to thrive.

What’s one way The Wilderness Society is working to protect the Clearwater Basin?
The Wilderness Society continues to help secure important funding for forest stewardship. This work includes:
- Decommissioning old roads to improve habitat and water quality
- Prescribed burns to reduce the chance of catastrophic wildfires
The Wilderness Society also hopes to win new wilderness protection in Idaho — specifically to link the Selway-Bitterroot Wilderness with the Frank Church-River of No Return Wilderness.
