General Information

Tule Red Tidal Restoration Project restored 420 acres of marsh habitat on the eastern edge of Grizzly Bay in the Suisun Marsh. The project creates self-sustaining tidal marsh to benefit listed fish and wildlife species, including delta smelt, longfin smelt, and salmonids. The project has been a collaboration between Westervelt Ecological Services, State and Federal Contractors Water Association, the California Department of Fish and Wildlife (CDFW), and many other resource agency partners.

The restoration of Tule Red will contribute to the 8,000-acre tidal marsh restoration requirements for the Central Valley Project and State Water Project Long-term Operational Criteria and Plan (OCAP) Biological Opinion. The restored site will also help meet the objectives of the Suisun Marsh Habitat Management, Preservation and Restoration Plan (SMP), and support the U.S. Fish and Wildlife Service Tidal Marsh Recovery Plan.

With construction on the site now complete, WES is the interim site manager. WES will turn the property over to the CDFW, who will manage and maintain it in the future. DWR will supply SWP funding to support the site in perpetuity.

More Information

The property was selected for tidal marsh restoration based on several key factors:
• Potential ecological value for fish
• Proximity to open water habitats frequented by Delta and Longfin smelt, as well as Chinook salmon
• Sediment supply and accretion rates are adequate to keep up with sea-level rise
• Contiguous with, and includes areas within the CDFW Grizzly Island Wildlife Area
