A host of reports and other public documents developed by the Matilija Dam Ecosystem Restoration Project since 2000 are organized into five main categories below, plus an Archive that serves as a repository for materials that are no longer directly relevant but may have historical and/or long-term public interest value. We will continue to update these folders as additional documents become available (i.e., both older reference documents and new Project reports).
Please note: when you click on an older link, the corresponding document will open in the same window, making it look like you’ve exited the site. If you click on the back arrow when you’re done, however, you’ll be returned directly to this page. (We are working to address this and a few other issues, thanks in advance for your patience.)
Finally, if you can’t find something you’re looking for please contact VCPWA-WP for assistance.
