Geographic Information System (GIS)

The Sacramento-San Joaquin Delta region often presents challenges to individuals with its combination of sheer size and diverse issue complexities. To better assist policymakers, engineers, stakeholders, and the many other parties interested in Delta water resources in understanding the region, the Specialized Areas Branch utilizes GIS to leverage a wide variety of geographic data specific to the Delta. The data are used to support Department-sponsored activities and to serve Delta-specific geographic data to other agencies, parties working in the Delta, and to the public at large.
