Just outside St. Helena, the Sulphur Creek Fish Passage Restoration Project has quietly reopened a vital pathway in the Napa River watershed—restoring more than 3 miles of habitat for native fish like steelhead trout.
At its core, the project removed a failed fish ladder (installed in the early 2000s), replaced a problematic bridge, and rebuilt the creek into a more natural, passable channel. What sounds simple took nearly a decade of planning and coordination, followed by about a year of construction, and an investment of roughly $6–7 million.
Who Made It Happen
This was a true multi-stakeholder effort, led by:

Engineering and technical contributors included firms such as Mark Thomas, Crawford & Associates, and other specialists supporting bridge design, hydrology, and environmental compliance.
A Moment of Recognition
On September 5, 2025, the project’s success was recognized in a gathering of stakeholders and donors. Mike Thompson presented commemorative sculptures—crafted by Blue Trout Studio—to major private donors.
The sculptures, inspired by the movement of fish and water, served as a fitting symbol of what this project achieved:
restoring motion, reconnecting habitat, and aligning a community around stewardship.
Congressman Thompson was notably generous in acknowledging the wide range of contributors—public agencies, nonprofits, engineers, and private donors—who made the project possible.
Why It Matters
The Sulphur Creek project is a reminder that even relatively small waterways play an outsized role in ecological health. It also shows what’s required to fix them:
time, funding, technical expertise—and sustained collaboration.
At Blue Trout Studio, it was an honor to contribute in a small way to a project that reflects the same natural forces that inspire our work.
