Conservation, Protection and Restoration


Millerton creek

NBTU is currently raising funds to support the restoration of Millerton Creek in western Marin County. Millerton Creek is a coastal stream that flows through Millerton Ranch into Tomales Bay in Marin County California. It historically supported a healthy population of steelhead, prior to the construction of a migration barrier created as part of a quarry operation operated by a former owner. The Ranch is now owned by the Marin Agricultural Land Trust and will be subject to a permanent conservation easement following its transfer to the current lessees in 2018. It is a working agricultural operation, and is now the focus of an integrated effort that includes restoration of the creek, riparian fencing and water quality improvement, and a carbon sequestration plan. The creek restoration effort involves a multiphase plan which will facilitate the recovery of the steelhead. In Phase I (currently underway), it will identify those factors limiting steelhead recovery, which will include partial design for the removal of the migration barrier. We are seeking funding for this project. Subsequent phases including implementation would build on Phase I.

Devils Gulch

Devil's Gulch 2015

North Bay Trout Unlimited has completed a significant project enhancing habitat in Devil’s Gulch, a key tributary to Lagunitas Creek in Marin County, California. Devil’s Gulch is critical habitat for endangered coho salmon and threatened steelhead populations along the Central California Coast. NBTU, together with the California Department of Fish and Wildlife and Dragonfly Consulting, restored woody structure in eight locations along this creek, reversing some of the adverse effects attributable to a history of logging in the area. This project is the latest effort by NBTU in their over 30 years of restoration work in the Lagunitas Creek watershed.

What will this project accomplish? By slowing down flows during periods of rainfall in winter, it provides shelter for fish during peak run-off periods and helps maintain spawning areas. This shelter will also allow juvenile fish to grow larger before they migrate out to sea in the spring. During summer, the woody habitat will result in the creation of pools and cover, keeping the creek cool and allowing fish to hide from predators. Please go to to learn why large woody debris is so important.

The North Bay Chapter of Trout Unlimited, and the coho and steelhead of Devil’s Gulch, are grateful to the California Department of Fish and Wildlife, the Marin Municipal Water District, California State Parks, Dragonfly Consultants, and Doug Gore for their assistance and collaboration in connection with this project; and to the California Department of Fish and Game and Patagonia for their financial support.
