From the mighty Colorado River to the Pacific Northwest’s vast Columbia River Basin, to the waters that converge in places like Alaska’s Bristol Bay and British Columbia’s Nootka Sound, rivers in the West flow with power and purpose. They’ve sustained human life for millennia, providing drinking water, food, thoroughfares and meaning to millions. These are living systems that shape landscapes and ways of life across generations.
Yet even the mightiest rivers need our commitment to their future. So we’re taking action alongside communities to do all we can for the rivers that need our help. Wherever we work, we find new ways to build bridges and come together. In Indigenous communities in Arizona, Alaska and British Columbia and beyond, TNC honors the authority of people with deep and lasting traditions tied to rivers. Where the return of the salmon brings a surge of life every summer, TNC is a trusted partner in protecting sustainable economies.

Ripples, Comebacks and Opportunities
What happens upstream ripples downstream. Stewards of rivers listen, learn and act together. As rivers come back, the water remembers: how to nourish, how to thrive, how to welcome back a chorus of life. By supporting thoughtful stewardship and honoring diverse ways of knowing, we provide opportunities for rivers to remain places of connection.
Season by season, living with the run
Tribal and local fishers in Bristol Bay read the salmon run like an unfolding story—watching the water, tracking returns and protecting a way of life shaped by the fish. Their deep knowledge and care help sustain one of the world’s last great wild salmon fisheries, season after season.

Where water slows and life returns
At Granite Creek, the Yavapai-Prescott Tribe partnered with TNC to heal a scarred stretch of river, clearing out industrial debris, planting cottonwoods and willows, and slowing the flow of water with natural structures to create renewed wetland habitat and a gift to future generations who will walk its banks.

Tending waters that carry salmon home
In the Columbia River Basin and waters across the Pacific Northwest, salmon nourish the land and the people who call it home. Meet some of the Indigenous and local stewards who are working in reciprocity with salmon to support their journey and sustain the cultural traditions rooted in their return.

Beauty of the Bay
As the easternmost arm of the Bering Sea, Bristol Bay is the meeting point for five major rivers, where wildlife thrives. Immerse yourself in breathtaking scenes of salmon, bears and seals in the Bay’s pristine headwaters.

Mimicking beavers restores riverscapes across the
Taking a page from beavers, TNC is leading river restoration across the Sagebrush Sea and Colorado River Basin, drawing on simple, nature-friendly engineering to slow the flow of water and revive habitat for songbirds, sage grouse, mule deer, and trout.

Healthy communities depend on healthy rivers
In Idaho's Upper Salmon Basin, over half of salmon and steelhead habitat is located on private lands. To continue TNC's longtime effort to restore these critical waters, our teams are working with private landowners to balance community needs with healthy natural systems.

Indigenous ways can bring rivers back to health
Vast tracts of Canada’s Pacific coast rainforest have been deeply impacted by historic industrial logging practices. So have many of the streams bringing wild salmon in from the sea. To bring back healthy salmon runs and preserve a way of life, Indigenous-led Salmon Parks are restoring what’s been lost.

People are working together for the Colorado River
The Colorado River is the lifeblood of the Southwest, bringing life to dry places. But that doesn’t mean there’s enough water to go around. So TNC is helping to find new opportunities to give the river a rest while still bringing water where it’s needed.

In Idaho, a salmon stream gets a second chance
Chinook salmon return to Idaho’s Lee Creek in a wondrous cycle of life that brings them 850 miles from the Pacific Ocean. By protecting places like this, TNC is showing how we can help their chances in a struggle for the survival of a species.


When we trace the path rivers have carved across Western U.S. and Canada, we learn how nature shapes us. Our river restoration work drives toward a common purpose: to safeguard these vital ecosystems for generations to come and renew our reverence for water.
