Stillaguamish Tribe Reclaims Marsh for Salmon Survival

The Stillaguamish Tribe is spearheading a significant multimillion-dollar restoration of the Stillaguamish River's marshy wetlands. This ambitious project, costing approximately $12 million, seeks to reverse decades of habitat degradation that led to the severe decline of Chinook salmon populations.

Historically, vast marshes covered the area before extensive conversion to farmland from the 1880s through 1920. Levees and a sea dike were built, constricting the river into a faster, narrower channel. The Tribe is now purchasing farmland to recreate the estuary's original flow.

By excavating trenches and easing water pressure, the restoration aims to re-establish the river delta as it existed nearly 150 years ago. These calmer marsh environments are crucial for juvenile Chinook salmon, providing essential feeding grounds and aiding their transition to the ocean.

The project is already showing ecological promise, with plant life returning and juvenile salmon observed in recently restored sections. Furthermore, the reconstructed wetlands successfully reduced flood impacts during recent record-breaking December flooding, benefiting downstream farms.

This restoration holds profound cultural and economic significance for the Stillaguamish people, whose traditions are deeply intertwined with salmon fishing. The return of healthy salmon populations is seen as an indicator of overall ecosystem health for the entire valley.
