About Tomales Bay Watershed Council Foundation (Tomales Bay Foundation)

Research confirms EIN 56-2464115 corresponds to the Tomales Bay Watershed Council Foundation (operating as Tomales Bay Foundation), a California 501(c)(3) incorporated in 2004 that now consolidates the former Watershed Council and Foundation activities. The Foundation is an all-volunteer, donor-facing nonprofit focused on watershed stewardship through water-quality monitoring, targeted scientific research grants, habitat restoration (notably Chicken Ranch Beach wetland planning), education, and partnerships with agencies such as the National Park Service and Marin County. Recent activity (2023–2026) includes multi-year water-quality sampling and an active student research grants program (annual RFPs and awards).

Notable achievements

Chicken Ranch Beach restoration design

Completed an advanced (60%) design and environmental planning for wetland enhancement and ditch realignment at Chicken Ranch Beach to reduce bacterial contamination; design planning and permitting work continued with secured planning grants in 2022 and 2024.

Ongoing, multi-site water-quality monitoring

Operates regular water-quality monitoring across the Tomales Bay watershed (sampling numerous sites multiple times per year) to track fecal coliform, turbidity, pH, temperature, salinity and other indicators and produce geomean reports for 2023–2025.

Student research grant program

Maintains an annual research grants program (Science Fund) supporting student and early-career projects addressing local priorities—sea-level rise, habitat use, water quality, land-use impacts—with awards and presentations required at local conferences.
