We develop a number of state-of-the-art models and analytical tools that describe how water flows, flood risk, and water quality in California’s rivers groundwater basins and the Sacramento-San Joaquin Delta.

DWR maintains several additional web portals containing data and maps. These portals remain unchanged.

Our web-based photo library, Pixel, features a vast collection of images of California’s natural landscapes, waterways, and other features of interest, available for free download.

We provide an access point to DWR Public forms. The Directory contains links to electronic versions of relevant and current public forms, providing citizens and employees with another resource to conduct business with the State of California.
