SWAMP Data Dashboard

• __SWAMP Stations__ – Geospatial and descriptive information about SWAMP monitoring sites.
• __Water Quality Results__ – Field and lab analysis results for chemical and physical parameters measured in water samples.
• __Toxicity

Summary

Results__ – Summarized results from aquatic toxicity tests. Summary records are entries in the database that summarize the results from multiple replicate toxicity tests of the same sample water.

• __Habitat Results__ – Data on physical habitat conditions typically collected alongside biological monitoring to provide context for interpreting water quality conditions. Includes scores for the California Stream Condition Index (CSCI) and Algal Stream Condition Index (ASCI).
• __Tissue

Summary

Results__ – Annual summary statistics of contaminant concentrations in aquatic organism tissue samples. The data are derived from raw individual and composite tissue sample results. These data are collected by SWAMP and its partners to support water quality assessments, identify trends, and inform water resource management.

The SWAMP Data Dashboard provides interactive visualizations and filtering tools to explore this data by region, parameter, and more. The SWAMP dataset is sourced from the California Environmental Data Exchange Network (CEDEN), which serves as the central repository for water quality data collected by various monitoring programs throughout the state. As such, there is some overlap between this dataset and the broader CEDEN datasets also published on the California Open Data Portal (see Related Resources).

This SWAMP dataset represents a curated subset of CEDEN data, specifically tailored for use in the SWAMP Data Dashboard. Access the SWAMP Data Dashboard: gispublic.waterboards.ca.gov/swamp-data/ _*This dataset is provisional and subject to revision. It should not be used for regulatory purposes._
