The Matilija Dam Ecosystem Restoration Project is a unique public-private partnership initiative to remove the obsolete Matilija Dam from the Ventura River watershed while addressing a host of related issues.
Since 1999, Ventura County Public Works Agency – Watershed Protection (Watershed Protection) has engaged in a multi-stakeholder effort to remove the Matilija Dam 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 and restore ecosystem function.
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 publications.
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 also look forward to your comments and suggestions to help ensure that this new version of MatilijaDam.org serves as a reliable and up-to-date source of information about the Matilija Dam Ecosystem Restoration Project.
Notices & Highlights
The comment period for Public Scoping for the preparation of a Subsequent Environmental Impact Report for the MDERP closed on October 14, 2020. A Draft SEIR is currently under development, with public release and community meetings anticipated in late Spring 2021. Please see the Environmental Compliance page for additional information.
On March 25, 2021 the California State Coastal Conservancy awarded $734,730 to Watershed Protection to advance design planning and update environmental documentation for the Camino Cielo Bridge Replacement Project.
A six-month Community Update on the MDERP was presented by Watershed Protection and Project partners c/o the Ventura River Watershed Council on the evening of Thursday, April 1, 2021. More in-depth Technical Updates were also provided by Watershed Protection and the Project’s lead technical consultants that same afternoon. Both meetings were held virtually due to Covid-19 precautions. Presentations and recordings from the Spring 2021 Community Update (with Technical Update highlights) are available at the Watershed Council’s Past Meetings archive, along with similar materials from the Project’s Spring 2020 (February) and Fall 2020 (October) updates.
