Clearwater Basin

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.

Stretching from the jagged peaks of the Bitterroot Mountains in the east to river canyons in the west, Idaho’s Clearwater Basin is home to the North Fork of the Clearwater and the Lochsa rivers.

Since Lewis and Clark passed through the area two centuries ago, the Clearwater has been threatened by logging and road construction. We are helping to restore key wildlife and fish habitat.

Why the Clearwater

The Clearwater Basin encompasses a million acres of forests, rivers and mountains, providing world-class habitat for Canada lynx and wolverines.

Work we’re doing
