The Tomales Bay Watershed Council Foundation was incorporated in 2004 as a 501(c)(3) nonprofit corporation to fund activities of the Tomales Bay Watershed Council, a related entity that primarily does water quality testing at tributary streams of Tomales Bay, and provides a forum for agencies and other organizations active in the watershed. Under a 2021 Fiscal Sponsorship Agreement between the two entities, the Foundation will support the Council and will also continue to implement projects of habitat restoration, education, scholarships, community development, research and improvements around the Bay.

The Tomales Bay Watershed Council (TBWC) was formed in 1999 by the region’s stakeholders with an interest in improving the watershed’s vital natural resources.  The TBWC includes representatives from local, state and federal agencies, environmental organizations, citizen and residential groups, agricultural and shellfish industries, recreational interests and individual residents. Learn more about who we are.

Operating as a consensus based organization, the TBWC provides a forum to advance watershed restoration and implement strategies to improve quality of life. Learn more about our Stewardship.
