Use Cases

• Combine station/project location data with other CEDEN datasets for geospatial analysis of water quality trends.
• Map sampling station locations to analyze spatial coverage of California's environmental monitoring network.
• Use station identifiers as join keys to integrate field, sediment, and water column data from CEDEN.

Strengths

• Data originates from CEDEN, the California State Water Board's authoritative data system for surface water quality.
• Includes data from statewide sources, including research and volunteer organizations, for broad coverage.
• Last updated in March 2026, indicating recent maintenance.
