The Marin Municipal Water District (MMWD) is taking significant steps to protect the endangered coho salmon by advancing the Lagunitas Creek Watershed Enhancement Project.
After the successful completion of the initial restoration phase in Samuel P. Taylor State Park, the district is gearing up for Phase 1B, focusing on adding vital spawning habitats to benefit the creek’s delicate ecosystem.

Restoring Lagunitas Creek: A Win for Marin County Ecology
Lagunitas Creek flows through the heart of West Marin, traversing towns like Lagunitas-Forest Knolls, San Geronimo, and Olema.
It’s not just a picturesque feature of our community—it’s a lifeline for many wildlife species, particularly the endangered coho salmon. These fish depend on the creek’s gravel beds for spawning, but decades of erosion and environmental shifts have severely degraded their habitat.
To address this urgent need, the Marin Municipal Water District embarked on a multi-phase restoration project last year.
Phase 1A introduced natural materials like logs, boulders, and gravel across 4,450 feet of the creek in Samuel P. Taylor State Park.
The structures performed remarkably well, even withstanding the intense storm surges during February, which brought the highest water flows since 2005.
Phase 1B: Scaling Up Salmon-Friendly Habitats
This summer, Phase 1B will take restoration efforts to the next level.
With a $2.9 million budget backed by $2.8 million in state and federal grants, MMWD plans to enhance five additional sites along the stream.
Thousands of tons of gravel will be added to create new spawning beds, while gravel bars, tagged with special markers, will also help track gravel movement during future storms.
This makes the work not only restorative but also a key part of ongoing scientific monitoring.
The project timeline is already underway, with officials planning to solicit bids in April, finalize the contract in May, and complete construction by November.
For a project of this scale, efficiency is essential to meet the seasonal needs of Marin County’s aquatic ecosystems.
Why This Matters to Marin County and Beyond
Coho salmon play an integral role in the larger ecosystem, with their lifecycle directly benefiting other wildlife, including birds and bears.
But these fish are not just a critical environmental asset; they’re tied closely to Marin’s cultural identity.
The Lagunitas Creek Watershed is recognized as one of California’s premier habitats for coho salmon, making it a vital resource not just at a local scale but on a state and even national level.
Moreover, the project underscores Marin County’s leadership in ecological restoration.
Communities from Fairfax to Point Reyes Station have a direct stake in the health of Lagunitas Creek, including its value to tourism, recreation, and environmental education.
Learning From Past Success
Reflecting on the accomplishments of Phase 1A, the success of MMWD’s design in withstanding record-high flows serves as a testament to the effectiveness of well-planned, sustainable habitat restoration techniques.
As one of California’s most dynamic ecosystems, Lagunitas Creek is a perfect proving ground for innovative conservation strategies. These lessons provide a valuable template that can be applied to similar watershed projects across the Golden State.
The Long-Term Vision: Phase 1C and Beyond
Phase 1B is a crucial piece of the puzzle, but the work doesn’t stop there.
The final phase of restoration, Phase 1C, is still in the design and permitting stage.
Similar to the expansions seen in Phase 1B, Phase 1C will add enhancements to an additional five sites within Samuel P. Taylor State Park.
The goal is to maximize the creek’s spawning potential while maintaining its natural beauty and functionality.
For locals in San Anselmo, Mill Valley, and Novato, the broader success of this initiative is a point of pride, showcasing Marin County’s enduring commitment to the environment for future generations.
How You Can Get Involved
Residents and visitors alike can support restoration efforts in several ways:
- Volunteer: Many restoration projects in Marin County welcome volunteers. Keep an eye out for opportunities to engage with MMWD’s efforts.
- Donate: While much of the funding comes from grants, private donations help sustain complementary programs like environmental education and outreach.
- Stay informed: Visit the Lagunitas Creek Watershed Enhancement Project website to follow updates and milestones.
A Commitment to Marin’s Vibrant Future
As Marin County advances Phase 1B of the Lagunitas Creek Watershed Enhancement Project this summer, the area sets a shining example of how local action can have a ripple effect on biodiversity and beyond.
From the redwoods of Samuel P. Taylor State Park to the quiet hamlets of Woodacre and Inverness, this habitat restoration effort is more than a win for salmon—it’s a triumph for all who cherish Marin’s pristine natural heritage.
