Contaminant Data Display and Download Tool or CD3 is an innovative visualization tool for accessing water quality data for the San Francisco Bay-Delta and northern montane regions. It is the primary tool for accessing and downloading the San Francisco Bay Regional Monitoring Program’s (RMP) long-term dataset and other project data stored in SFEI's Regional Data Center (RDC). Data stored in SFEI’s RDC are comparable with the state’s data management business rules and are regularly exchanged with the California Environmental Data Exchange Network (CEDEN).
CD3 was recently redesigned to leverage SFEI’s other interactive mapping efforts. It debuts impressive new functionality, including enhanced spatial querying and dynamic statistical summaries. Other key benefits of the redesigned tool include:
- aggregating data from different projects and sampling events for an analyte
- accessing all data collected across multiple years for a project
- spatial querying by county, Water Board, hydrologic region, or user-defined area of interest
- generating surface model maps for RMP data
- selecting among several chart types for data analysis (e.g., mean and error; box and whiskers, histogram)
- downloading data as a tabular or spatially displayed dataset
- customizing and downloading charts for use in reports and presentations.
The tool is updated regularly with new datasets and has the flexibility to display all public data stored in SFEI’s Regional Data Center database.

California's EcoAtlas provides access to information for effective wetland management. The maps and tools can be used to create a complete picture of aquatic resources in the landscape by integrating stream and wetland maps, restoration information, and monitoring results with land use, transportation, and other information important to the state’s wetlands.
The California Environmental Data Exchange Network (CEDEN) is a central location to find and share information about California’s surface waters, including streams, lakes, rivers, and the coastal ocean.
