Washington Tribe Converts Farmland to Wetlands to Restore Chinook Salmon

Water returns to its old channels. The soil, saturated again, begins to support life.
The Stillaguamish Tribe removes levees to restore wetlands that salmon depend on for survival.

Along the river valleys of western Washington, the Stillaguamish Tribe is quietly dismantling a century of imposed geography — buying back ancestral farmland, tearing down levees, and coaxing wetlands back into existence. Their aim is the return of the Chinook salmon, a fish so central to their identity that its absence is not merely ecological loss but a kind of cultural silencing. In choosing to restore the land themselves, on their own terms, the tribe is offering a different answer to the question of who holds the knowledge and authority to heal a wounded landscape.

  • Chinook salmon populations in the Pacific Northwest have collapsed to a fraction of their historical abundance, threatening both the ecosystem and the cultural survival of tribes whose identity is inseparable from the fish.
  • Decades of agricultural levee-building drained the wetlands that salmon depend on for spawning and juvenile development, turning living nurseries into dry fields — and the Stillaguamish have watched this unravel in real time.
  • Rather than waiting for federal or state intervention, the tribe is systematically purchasing parcels of its ancestral territory and physically removing the levees, letting water reclaim the land it once shaped.
  • As water returns to old channels and marsh vegetation re-establishes itself, the restored wetlands are beginning to rebuild the chemical and biological conditions that Chinook salmon require to survive and reproduce.
  • Other Indigenous nations and conservation scientists are watching closely — if this tribal-led model succeeds, it could redefine how environmental recovery is organized and governed across the region.

In the river valleys of western Washington, the Stillaguamish Tribe is executing a deliberate reversal of more than a century of land transformation. Acre by acre, they are purchasing farmland within their ancestral territory and tearing down the levees that have kept water at bay for generations. What rises in place of drained fields is wetland — shallow water, marsh grass, and the kind of living landscape that once defined this region before settlers arrived with plows and drainage systems.

The urgency behind this work is real. Chinook salmon, once so abundant they darkened the rivers on their return, now arrive in fragments of their historical numbers. For the Stillaguamish, the fish are not a resource among many — they are central to culture, food security, and identity. Fishing rights that the tribe has held for generations have grown increasingly hollow as the salmon themselves have disappeared. The levees that made farming possible were never neutral infrastructure; they were a reordering of the landscape that displaced the ecological systems sustaining human communities here for thousands of years.

Once the tribe acquires a parcel, the transformation begins. Levees are breached or removed entirely. Water finds its old channels. Saturated soil begins supporting willows, sedges, and the dense plant life that provides salmon with food, shelter, and the precise conditions they need to thrive. This is not abstract conservation theory — it is hands-on reconstruction of a functioning ecosystem.

What distinguishes the effort is its authorship. The Stillaguamish are not waiting for outside conservation groups or government agencies to act. They are directing their own restoration, drawing on both ecological science and deep traditional knowledge of how this land actually works. Other Indigenous nations facing similar crises are watching closely. If Chinook runs return to these valleys, the implications for how environmental recovery is led — and by whom — could extend far beyond the Pacific Northwest.

In the river valleys of western Washington, the Stillaguamish Tribe is undertaking a deliberate reversal of a century of land use. They are buying farmland—acre by acre—in the territory their ancestors inhabited, and they are tearing down the levees that have held back water for generations. What emerges in the place of drained fields is wetland: shallow water, marsh grass, the kind of landscape that once dominated this region before settlers arrived with plows and drainage systems.

The purpose is specific and urgent. Chinook salmon populations in the Pacific Northwest have collapsed. The fish that once returned to these rivers in numbers so vast they darkened the water now arrive in fragments of their historical abundance. The tribe believes that restoring the wetlands—the nurseries and spawning grounds that salmon need—offers a path toward bringing those runs back. It is an act of ecological restoration, yes, but also an assertion of sovereignty and knowledge. The Stillaguamish are not waiting for federal agencies or state governments to solve a problem they have watched develop for decades. They are solving it themselves, on their own land, using methods rooted in understanding how this landscape actually works.

The project represents a significant financial and logistical commitment. The tribe has been systematically acquiring parcels within its traditional territory, land that had been converted to agriculture in the late 1800s and early 1900s. Once they own it, the work of transformation begins. Levees—the earthen barriers built to keep rivers confined and fields dry—are removed or breached. Water returns to its old channels. The soil, saturated again, begins to support the vegetation that salmon depend on: willows, sedges, the dense plant life that provides food, shelter, and the chemical conditions salmon need to thrive.

This is not theoretical restoration. The Stillaguamish have watched their salmon decline in real time. The fish are central to their culture, their food security, and their identity. For generations, they have held fishing rights in these waters, but those rights have become increasingly hollow as the fish themselves have vanished. The levees that drain the wetlands are not neutral infrastructure—they are monuments to a particular vision of land use, one that prioritized agricultural production over the ecological systems that sustained human communities for thousands of years before farming arrived.

The tribe's approach reflects a growing recognition among Indigenous nations and conservation scientists that large-scale ecosystem restoration requires returning land to something closer to its pre-industrial state. Wetlands are not wastelands to be drained and developed. They are among the most productive ecosystems on Earth, nurseries for fish and birds and countless other species. They also filter water, store carbon, and buffer communities against flooding. By converting farmland back to wetlands, the Stillaguamish are not simply trying to save salmon. They are rebuilding the foundational infrastructure of a living landscape.

What makes this effort distinctive is that it is being led by the tribe itself, not imposed by outside conservation groups or government agencies. The Stillaguamish have the knowledge, the motivation, and increasingly, the resources to direct their own restoration. They are making decisions about their territory based on their own understanding of what that territory needs and what their people need from it. This model—tribal-led, land-based, rooted in both ecological science and traditional knowledge—is being watched closely by other Indigenous nations facing similar challenges. If the Stillaguamish succeed in restoring Chinook runs, the implications could reshape how environmental recovery happens across the Pacific Northwest and beyond.

La Conversación del Hearth Otra perspectiva de la historia
Inventor

Why is the Stillaguamish Tribe buying farmland specifically? Why not just work with existing wetlands?

Model

Because the wetlands are gone. They were drained a century ago to make room for farms. If you want salmon back, you have to give them the habitat they evolved in. That means undoing the drainage.

Inventor

But farmers are using that land now. What happens to them?

Model

The tribe is buying the land—they're not seizing it. Farmers can sell or not. But the economic logic is shifting. A farm produces income for a few decades. A restored wetland produces salmon, filters water, and supports an entire ecosystem indefinitely. The tribe is betting on the longer timeline.

Inventor

How do you know removing levees will actually bring salmon back?

Model

Because salmon were here before the levees. The fish didn't evolve in drained fields. They evolved in wetlands—shallow water, vegetation, the whole system. You restore the habitat, the fish return. It's not guaranteed, but it's the only strategy that makes biological sense.

Inventor

Is this just environmental nostalgia? Trying to recreate the past?

Model

No. It's recognizing that the past worked. Salmon were abundant. The ecosystem was stable. We broke it by draining it. Restoration isn't nostalgia—it's acknowledging that we made a mistake and fixing it.

Inventor

What's at stake if this fails?

Model

The Chinook disappear entirely from these rivers. The tribe loses a core part of their identity and food security. And the region loses a keystone species that holds the whole ecosystem together. The stakes are existential.

Inventor

Could other tribes do this?

Model

Yes. And some are. But it requires land, money, and political will. The Stillaguamish have all three right now. If they succeed, it becomes a blueprint. If they fail, it becomes a cautionary tale. Either way, they're showing what's possible.
