General Wetlands Information

The California Resources Evaluation System (CERES) and the California Wetlands Information System (CWIS) are programs of the California Resources Agency. These resources are intended to provide comprehensive wetlands information to the general public, the educational community, and government agencies. Here you can find a compilation of public and private sector information including maps, environmental documents, agency roles in wetlands management, restoration and mitigation activities, regulatory permitting, and wetland policies.
