The inaugural version of the report is based solely on the surface water datasets available via the Surface Water Ambient Monitoring Program (SWAMP) and in future years we hope to expand this to include the groundwater, drinking water and water resource datasets available in our state.  Our goal is to use data to inform both data storytelling (as in this inaugural report) and water quality indicators, including watershed report cards.

The 2017 Water Quality Status Report is organized around seven major themes that our team thought both individually and collectively tell important stories about the overall health of our state's surface waters.  Each theme-specific story includes a brief background, a data analysis summary, an overview of management actions, and access to the raw data.  All of the data in the stories is available at the State of California's Open Data Portal, https://data.ca.gov/dataset/2017-california-water-quality-status-report.
