State Water Resources Control Board - Data and Databases

Data and Databases

The Water Boards’ have a number of databases that include Summary Reports and Geographic Information System (GIS) map interfaces. Many also store or link to more detailed documents and technical reports.



The Water Boards will host a series of events in spring 2016 to enhance the availability and integration of the Water Boards’ key datasets:

  • Data Fair (March 18, 2016) - A combination of thought-provoking presentations and access to dataset stewards. Presentations will highlight projects and concepts to synthesize water resource related data, and lay out elements of the Water Boards' strategy to increase the availability and usefulness of our vast water resource related data and information.
  • Data Innovation Challenge - (March 18 - April 22) - A competition of brainstorming and computer programming that will draw together the talent and creativity of software developers and designers to create apps, visualizations, and other tools that can help better harness the Water Boards' data.
  • Water Quality Science Symposium - (June 29) - the 1st Annual Water Quality Science Symposium follows the Water Boards' Data Fair and Data Innovation Challenge, with the focus being on the use of data by other programs and Departments.
