    The Water Boards' Surface Water Ambient Monitoring Program (SWAMP) is hosting the 2nd Annual Water Quality Health Indicator and Data Science Symposium, with the focus being on the use of data by other programs and Departments. For more information, go to the event homepage.





Users can also search the site map, which catalogues the datasets referenced in all of the categories above on a single page.

In addition, a subset of the datasets maintained by the Water Boards can be found on the State of California's Open Data Portal under the 'Water' category. That platform provides web services that enhance data accessibility, and we plan to continue adding datasets to that platform in the future. Note that the datasets found on that site mirror some of the datasets provided through this Water Boards portal.
