Clearwater Basin

Logging, road construction and reckless off-road vehicle use threaten Idaho’s Clearwater Basin, one of the wildest natural landscapes in the lower 48 states.

The Clearwater Basin encompasses millions of acres of forests, rivers and mountains just south of Idaho’s northern panhandle, providing habitat for wildlife such as wolves, elk, mountain lions, mountain goats and fish including Chinook salmon and steelhead trout. The Clearwater Basin's 1.2 million acres of Roadless Areas also provide world class recreation for backcountry skiers, hunters, backpackers and hikers.

Little of the Clearwater Basin is permanently protected, and we need to remedy that. The Wilderness Society is working in the Clearwater Basin to gain permanent protection for wilderness and rivers, and preserve landscape connections that would allow species to safely travel between Central Idaho and Western Montana, and to help secure important federal funding for stewardship of the land.

Wildlands designation

The Wilderness Society has long been focused on permanently protecting landscapes in the Clearwater Basin that support robust wildlife populations and great recreational values. We have helped develop a proposal that would permanently protect over 500,000 acres of the Clearwater Basin and 170 miles of its rivers.

The Wilderness Society is a leader in the Clearwater Basin Collaborative (CBC), which represents conservation, recreation and business interests, among others. The coalition seeks to develop a long term vision for the future of the Clearwater Basin.


The Wilderness Society has identified the most important fish and wildlife habitat in the Clearwater Basin for permanent protection from logging, road-building and off-road vehicle abuse. Specifically, we hope to do this by designating 500,000 acres here as federal wilderness or under other special status to protect the landscape’s wild character.  

Wild and Scenic Rivers

The Clearwater Basin’s 2,200 miles of wild rivers provide crucial spawning habitat for Chinook salmon and bull and steelhead trout, and great recreation opportunities for anglers and whitewater enthusiasts. We are working to protect over 170 miles of these waterways as “wild and scenic rivers.”

Conservation funding

We are working with lawmakers to ensure that the Clearwater Basin receives appropriate federal funding through land management agencies to implement habitat restoration projects. We are advocating for the funding of projects including decommissioning old roads to improve habitat and water quality, performing prescribed burns to reduce the chance of future catastrophic wildfires and reducing infestation of invasive weeds.

Preparing for the effects of climate change

With climate change, temperature and precipitation patterns are likely to shift in the Crown of the Continent region, stressing wildlife populations. The Clearwater Basin plays a vital role in connecting several areas to the Crown of the Continent ecosystem in northwest Montana to wild lands in Central Idaho. Maintaining and restoring connectivity between landscapes like these is one of the most important steps that can be taken to ensure the success of ecosystems and wildlife facing challenges from a changing climate.

One of the most dynamic, healthy and natural landscapes in the lower 48 states, Idaho’s Clearwater Basin includes millions of acres of rugged forests, rivers and mountains.

    On Monday, September 26, the Colorado Bureau of Land Management state office announced that it will be pursuing a master leasing plan in Southwest Colorado. The statement comes after the agency engaged in an unprecedented public outreach campaign that consisted of a series of public meetings and the formation of a public working group that resulted in the submission of hundreds of comments to the local Tres Rios field office.

    Today the House of Representatives approved H.R. 845, the National Forest System Trails Stewardship Act by Representatives Cynthia Lummis (R-WY) and Tim Walz (D-MN). The legislation would keep more trails across the nation open and accessible by expanding the use of volunteer and partner organizations and providing increased focus on a handful of priority areas around the country.

    With very few legislative days left in the 114th Congress, this bill has no chance of being adopted and would do too little to protect wild, cultural and historic lands, including the critically important Bears Ears area.
