The Stillaguamish Tribe is buying riverfront land and removing levees to rebuild tidal wetlands, aiming to revive threatened Chinook salmon while reshaping flood risk tradeoffs.
A levee breach is rewriting the landscape at the mouth of the Stillaguamish River, turning protected farmland into a tidal marsh built for salmon recovery.
At the river’s edge north of Seattle. the Stillaguamish Tribe removed about two miles of earthen levee. allowing tides to move into newly restored wetlands for the first time in more than a century.. The result is a 230-acre habitat area now being managed as part of a wider push that includes buying additional riverfront property. with tidal marsh described as a key setting for young Chinook salmon.
This kind of restoration is more than an ecological makeover. It changes how water moves through a landscape, shifting long-standing flood protections and forcing communities to renegotiate what “safe” land use looks like.

Work on the new habitat. locally known as zis a ba 2. is also designed to help nature speed up the rebuilding process.. Restoration crews dug channels into farmland before the levee was breached. creating pathways that tides could use to spread and refresh the area.. In the process. workers uncovered older cultural materials. including shell deposits that point to long human presence near the river mouth.
The ecological signals emerging from the site are already visible.. Shorebirds have returned to forage in the wet mud. and the restored tidal environment is being framed as a “floodplain connection” project. restoring the relationship between the river and the wider tidal landscape that was restricted for generations.

Meanwhile. the restored marsh is also being tested by the kinds of extreme events that are becoming all too familiar in the region.. Floodwaters later tore through portions of the area. reshaping parts of the land and delivering sediment and uprooted trees that can function as raw material for early wetland development.. The same storms that strained the landscape elsewhere underscored a central question for the region: how do you reduce damage from future flooding while also protecting livelihoods?
Alongside the tribe’s habitat work, farmers and local officials face the practical realities of living in a flood-prone floodplain.. For residents near the Tom Moore Slough area. levees are what make farming and day-to-day life possible. particularly when high tides and storms threaten older infrastructure.. Some landowners are seeking repairs after damage and weather-related wear, and they argue that solutions should also keep farmland viable.

The negotiations are not simple, and tradeoffs are unavoidable.. The tribe’s approach aims to give salmon more space by converting some land to tidal habitat. while farmers emphasize that there are limits to how much land can shift away from crops.. Even so. some residents say they can support certain levee removals if it comes with tangible benefits for the people who farm nearby.
For the Stillaguamish Tribe, the goal extends beyond acres and engineering. Restored habitat is being positioned as a route toward a future in which salmon once again support the culture and economy of the river, including for younger generations. Misryoum
In the long run. projects like this could offer a model for coastal and river restoration: not just adding habitat. but redesigning the rules of flood management so ecosystems and communities can both adapt.. That is the promise the tribe is betting on with every breach, purchase, and newly formed wetland.
