The Matilija Dam Ecosystem Restoration Project is a unique public-private partnership to remove the obsolete Matilija Dam from California’s Ventura River watershed.
Since 1999, Ventura County Public Works Agency – Watershed Protection (Watershed Protection) has engaged in a multi-stakeholder effort to remove the obsolete Matilija Dam (muh-TIL-i-hah) from Matilija Creek, the Ventura River’s largest tributary. The Matilija Dam Ecosystem Restoration Project (MDERP or Project) is a watershed-scale endeavor with multiple components that will enhance the Ventura River watershed to benefit native wildlife, restore ecosystem function, and enhance local water resilience.
The benefits of Project investments over the next 10+ years will include:
- Modernizing downstream infrastructure to enhance flood protection, water supply reliability and community climate resilience while addressing potential liabilities related to the obsolete dam and associated facilities;
- Catalyzing job creation and economic stimulus at the local, regional and statewide levels;
- Restoring natural sediment transport and ecosystem function to enhance floodplain, riparian and near-shore coastal habitats;
- Enhancing outdoor recreation opportunities and equitable access to the watershed’s natural amenities for present and future generations;
- Conserving water and protecting habitat through sustained treatment of Giant Reed and other invasive plant species; and
- Renewing access to prime spawning and rearing habitat in the Matilija Creek headwaters for the federally-endangered southern California steelhead.
The essential components of the Project can be found on the Overview page, with more detailed information provided elsewhere throughout the site.
Please see Notices and Highlights below for a summary of recent and forthcoming events and other updates.
We appreciate your interest in this comprehensive effort to re-wild the Ventura River headwaters while helping to prepare downstream communities for a more resilient water future. We look forward to your comments and suggestions to help ensure that MatilijaDam.org serves as a reliable source of information about the Matilija Dam Ecosystem Restoration Project. Please visit the Project landing page at Ventura County Public Works Agency for additional information.
